The OTC-X1 Examined: Testing a 1950s Flying-Saucer Design

October 26, 2026

Robotics researcher Dr. Kyaw Min Naing has spent three years recreating the OTC-X1, a 1950s flying saucer designed by American inventor Otis T. Carr. Using modern engineering, electromagnetic simulations, and custom-built prototypes, Naing’s “Project Vimana” is investigating Carr’s claims of propulsion through electromagnets, counter-rotating components, and an unusual energy accumulator called the Utron. Although his experiments haven’t demonstrated anti-gravity effects, his work is turning a historical mystery into a testable engineering project.

The Journey From Drones to Flying Saucers

Dr. Kyaw Min Naing’s interest in unconventional aerospace technology grew from a background in mechanical engineering, robotics, and autonomous unmanned aerial vehicles. Originally from Myanmar, he studied mechanical engineering at Victoria University College from 2012 to 2015 before earning a bachelor’s degree in Mechatronics, Robotics, and Automation Engineering at the University of Wolverhampton in the United Kingdom in 2017. He subsequently pursued doctoral research in engineering at Wolverhampton, investigating how electric drones could remain airborne for extended periods by receiving electrical power wirelessly. His doctoral thesis, dated 2022, was titled Design of Autonomous Sustainable Unmanned Aerial Vehicle: A Novel Approach to Its Dynamic Wireless Power Transfer. The research brought together autonomous navigation, power electronics, electromagnetic coupling, and energy management to address one of the fundamental limitations of battery-powered aircraft: their relatively short endurance.

His doctoral work examined reactive wireless power transfer, which uses electromagnetic coupling to transmit energy from a powered source to a separate receiver without a physical electrical connection. Unlike conventional battery charging, the long-term objective was to provide electricity to a drone while it remained airborne, potentially reducing its dependence on heavy onboard batteries. In a September 2020 paper published in the Journal of Multidisciplinary Engineering Science and Technology, Naing and his coauthors explored wireless power transfer for long-distance UAV operations. Their research described a development platform incorporating a Raspberry Pi 3B, a Navio 2 flight controller, and a 200-watt wireless power transfer module. The paper examined practical challenges involving transmission efficiency, sensor integration, flight stability, and the reliability of power delivery to moving aircraft. While this experimental work didn’t establish indefinitely sustained flight, it provided experience with electromagnetic systems that would later become relevant to the OTC-X1 reconstruction.

Naing also participated in research involving artificial intelligence and robotics. A paper presented at the 2018 Intelligent Systems Conference in London and published in 2019 examined the application of deep learning to UAV search-and-rescue operations. The work used convolutional neural networks, including techniques based on the LeNet architecture, to investigate image recognition for aerial applications. Beyond his research, Naing served as a visiting lecturer at the University of Wolverhampton from August 2018 to July 2019, teaching signal processing and supervising student assessments. He subsequently worked as a robotics engineer at the Academy of Robotics in Norwich during 2022. His professional profile also describes independent research into energy generation and efficiency improvements in Myanmar and Oman between January 2023 and February 2026, including investor-supported development associated with Moonrock Research and Development.

Following his doctoral studies, Naing says he declined opportunities in academic teaching and industrial research to pursue a considerably more unconventional ambition: building a flying saucer. His interest wasn’t primarily in extraterrestrial explanations for UFO sightings, but in whether an unconventional aircraft could be engineered using technology available to human inventors. Rather than beginning with an entirely original propulsion concept, he searched for historical designs with enough surviving documentation to support a reconstruction. Carr’s OTC-X1 stood out because its architecture combined recognizable electrical and mechanical components with claims about gravity modification and self-sustaining energy generation. Naing eventually organized his investigations under the name Project Vimana, documenting his research and experimental hardware on YouTube. On October 24, 2026, he presented his findings to the Alternative Propulsion Engineering Conference (APEC), explaining both the progress he’d made and the considerable limitations he’d encountered.

Otis T. Carr and the OTC-X1 Flying Saucer

American inventor Otis T. Carr emerged during the flying-saucer enthusiasm of the 1950s, a period when public fascination with unidentified aircraft intersected with the rapidly developing technologies of the early Space Age. In 1957, Carr and his company, OTC Enterprises, began publicly promoting an unconventional spacecraft that he claimed could travel through space using a combination of electromagnetism, rotational motion, and naturally occurring energy. His proposed OTC-X1 spacecraft was envisioned as a circular vehicle approximately 45 feet in diameter, containing multiple rotating sections and an unusual central power system. Carr claimed that his technology could overcome the limitations of rocket propulsion and potentially enable travel to the Moon and other planets. He also associated his work with the inventions of Nikola Tesla, claiming to have known Tesla during the 1920s, although Naing says he found no verifiable historical evidence supporting that relationship.

Carr’s proposed propulsion system differed dramatically from conventional aircraft or spacecraft. Instead of expelling high-velocity exhaust, the OTC-X1 supposedly relied on interactions among twelve electromagnets arranged around its perimeter, six metallic plates, several smaller electrical accumulators, and a larger central component called the Utron. Major structural sections were intended to rotate in opposite directions, while the passenger cabin remained stationary. Carr claimed that the rotating assemblies could recover energy, maintain electrical power within the machine, and produce an effect he sometimes associated with magnetism and gravity. He also described the possibility of manipulating electrical power to individual electromagnets to steer the spacecraft. Some accounts included a luminous blue-green glow surrounding the vehicle, supposedly associated with electrical activity during operation. Although these descriptions were unusually detailed for a flying-saucer proposal, they didn’t establish a complete physical explanation for how the craft would generate thrust.

The most widely publicized test of Carr’s technology was scheduled for April 19, 1959, at Frontier City near Oklahoma City. A six-foot-diameter prototype, reportedly weighing approximately 600 pounds, was supposed to demonstrate the operating principles of the larger spacecraft by rising several hundred feet into the air. Thousands of spectators gathered for the event, but the promised flight never occurred. Contemporary reporting and later historical investigations describe an incomplete machine, electrical or mechanical difficulties, and a demonstration repeatedly delayed before being canceled. Carr himself wasn’t present for the anticipated launch, reportedly because of illness. The failure was particularly damaging because Carr had made ambitious public promises about the capabilities of his invention, including proposals for a crewed lunar flight later that year. Without a successful demonstration or independent performance measurements, the OTC-X1 remained an unverified technological claim.

Carr did receive U.S. Patent 2,912,244 on November 10, 1959, but the document was titled Amusement Device, not a propulsion system or gravity-control apparatus. Filed on January 22 of that year, the patent described a stationary entertainment attraction in the shape of a spacecraft. Its counter-rotating assemblies, simulated machinery, hydraulic movement, and projected imagery were intended to create the impression of an interplanetary journey for passengers. The patent even described electromagnets and conical structures as visual elements of the attraction, rather than establishing a mechanism for spaceflight. Carr’s subsequent history included financial and legal problems. In 1961, an Oklahoma appellate court upheld his conviction for selling securities without registration, with a $5,000 fine imposed. Later accounts from former associate Ralph Ring claimed that functioning Carr spacecraft had actually flown, but those stories weren’t accompanied by independently verified flight records or instrument data. For Naing, the result was an intriguing historical puzzle: a famous flying-saucer design containing recognizable engineering components, but no demonstrated evidence that the complete machine could operate as claimed.

Reconstructing the OTC-X1 Component by Component

Naing began by separating Carr’s surviving documentation into distinct categories of historical evidence. These included promotional brochures, radio interviews recorded during 1957 and 1958, Carr’s published writings, thirteen sheets of model-construction plans dating from 1958, and the 1959 amusement-device patent. Although the material describes a recognizable spacecraft architecture, Naing found that no single document provides an operational blueprint. The construction plans identify component shapes, their relative positions, and certain materials, but omit electrical specifications essential to reproducing the machine. There are no definitive operating voltages, coil winding counts, current requirements, capacitor values, magnetic field measurements, or switching sequences. Carr’s interviews sometimes describe how the machine was supposed to behave, but rarely explain how that behavior would be achieved. Reconstructing the OTC-X1 would therefore require interpreting incomplete historical information and supplying missing engineering details through independent design work.

Naing organized the proposed spacecraft into seven principal systems: twelve perimeter electromagnets, a central Utron accumulator, six aluminum plates described as capacitors, opposing rotating structural assemblies, six smaller Utrons or energy coils, an electrical switching and control system, and a passenger cabin intended to remain stationary. This breakdown allowed each subsystem to be investigated separately, using conventional engineering methods before attempting to understand its role in the complete machine. His SolidWorks models reproduced the general arrangement while introducing practical construction materials, bearing assemblies, wiring paths, and mechanical supports. Crucially, Naing distinguishes features explicitly described by Carr from those he selected himself. The distinction matters because a modern reconstruction can demonstrate the behavior of the chosen implementation without necessarily proving what Carr originally intended. It also prevents engineering decisions made decades later from being mistaken for authentic details of the historical design.

The experimental program developed through five principal prototypes beginning in 2023. Naing’s first machine, Version 1, was an experimental motor-generator system. Subsequent Versions 1.1 and 1.3 investigated other unconventional generator and energy-recovery concepts, providing practical experience with rotating electrical machinery before he attempted a direct OTC-X1 reconstruction. Version 2, his first dedicated flying-saucer prototype, entered computer-aided design in October 2024. He fabricated structural components in November, assembled and wired the magnetic system during December, and completed a full rotation test on February 11, 2025. Further experimentation in June 2025 investigated an arrangement in which only the inner disc rotated. These early tests established that the assembly could be constructed and operated mechanically, but weren’t demonstrations of unconventional thrust or gravity modification.

Version 2.1 introduced a redesigned supporting frame and additional refinements to the mechanical arrangement. Naing produced 3D-printed structural joints during March 2025, weighed individual components in April, assembled the revised machine in May, and completed additional wiring during June. The experimental apparatus incorporated a plywood rotating disc, wooden support arms, tubing, twelve C-shaped electromagnets, six aluminum plates, six smaller Utrons, and a larger central Utron formed from cast bismuth. A copper central shaft ran through bearings and could also serve electrical functions associated with grounding or slip-ring connections. The external flying-saucer shell and passenger compartment weren’t included, leaving the mechanical and electrical systems exposed for observation and adjustment. Rather than building a visually complete spacecraft, Naing had created an open-frame laboratory apparatus capable of examining the physical behavior of Carr’s proposed components individually and in combination.

Twelve Electromagnets and the Challenge of Magnetic Control

The twelve perimeter electromagnets are among the most technically important features of the OTC-X1 architecture. In Naing’s reconstruction, each electromagnet uses a C-shaped ferromagnetic core wrapped with copper wire, concentrating magnetic flux through the metal and across an air gap. The arrangement resembles the magnetic circuits found in conventional motors, transformers, industrial lifting magnets, and electromagnetic actuators. The coil’s ability to generate magnetic flux depends on the product of its winding count and electrical current, while the geometry and magnetic permeability of the core determine how efficiently that flux is guided. Electrical steel can have a magnetic permeability hundreds or thousands of times greater than air under suitable conditions, making the air gap a major source of magnetic reluctance. Increasing the gap generally reduces the achievable magnetic field for a given excitation, while increasing current can eventually drive the core toward magnetic saturation, often around 1.5 to 2 tesla for common electrical steels.

Carr reportedly believed that eddy currents could enhance the magnetic performance of his apparatus, possibly allowing the iron cores to exceed their normal saturation limits. Naing’s investigation found the opposite behavior predicted by conventional electromagnetic theory. Eddy currents are circulating electrical currents induced within conductive materials by changing magnetic fields, and they generally create resistive heating and losses. In transformers and motors, these currents can consume substantial power without contributing useful output. Engineers typically reduce them by constructing magnetic cores from thin, electrically insulated laminations rather than solid metal blocks. Under simplified conditions, eddy-current losses increase approximately with the square of lamination thickness and operating frequency, making thin insulation-separated steel sheets particularly useful in systems with changing magnetic fields. Naing followed this established approach, cutting individual steel laminations, applying insulating varnish, and assembling them into C-shaped cores. His workshop documentation shows the lamination and varnishing process during October and November 2024.

The electromagnetic coils also required specialized manufacturing equipment. Naing initially experimented with smaller coils wound on 3D-printed bobbins before developing larger windings applied directly to the C-shaped magnetic cores. Because a closed magnetic core can’t simply be placed onto a conventional winding spindle, he designed a dedicated coil-winding apparatus. The machine used wooden discs to support the core, a rotating shaft, a hand-operated drive, and a wire guide to distribute the winding evenly. He completed the custom tool in approximately five days during November 2024. Subsequent fabrication involved cutting and insulating steel, preparing bobbins, winding copper wire, assembling magnetic cores, and testing the finished coils. By August 2025, his photographs documented extensive coil fabrication and testing, including numerous reels of copper wire and completed magnetic assemblies. The process illustrates how much engineering work can be hidden behind a historical drawing that simply identifies a component as an electromagnet.

Electrical switching presented another major obstacle because Carr described mechanically operated contacts without providing a complete timing sequence. Electromagnetic coils store energy in their magnetic fields and resist sudden changes in current, meaning that abruptly interrupting their electrical supply can produce high-voltage transients. Mechanical contacts exposed to repeated inductive switching can suffer arcing, erosion, and eventual failure. Naing instead implemented electronic control using a small computer to monitor rotor position and switch the electromagnets, with protective circuitry to manage inductive energy. Oscilloscope measurements recorded switching signals around 4 kilohertz during February 2025. In June, he also tested three-phase electrical operation, reporting approximately 236 volts, 6 amperes, and a power factor of 0.15. Those readings indicate a strongly reactive electrical load, with much of the apparent power associated with energy cycling through the magnetic fields. A simple single-phase interpretation gives approximately 210 watts of real power, although the correct three-phase calculation depends on how the voltage, current, and power factor were measured. These results provide useful electrical characterization, but don’t demonstrate lift, thrust, or excess energy production.

Capacitor Plates, Counter-Rotation, and the Propulsion Problem

Carr’s design also incorporated six metallic plates arranged around the perimeter of a rotating disc, which he described as capacitors capable of storing and releasing electrical energy. Naing reconstructed these components using six aluminum sheets folded around the edge of a plywood disc, positioning them so that they pass directly through the magnetic gaps of the twelve surrounding electromagnets. However, the historical documentation doesn’t establish the complete electrical geometry of the proposed capacitors. A conventional capacitor requires two conductive electrodes separated by a dielectric material, with its capacitance determined by electrode area, spacing, and the dielectric’s electrical properties. Although isolated conductors possess some capacitance relative to their surroundings, Carr’s drawings don’t identify the electrode pairs or electrical connections necessary to calculate useful energy storage. Naing’s reconstruction therefore reproduces the visible geometry while leaving the electrical function open to experimental investigation.

Moving aluminum through magnetic fields also introduces a well-understood physical effect that could interfere with the machine’s rotation. Aluminum isn’t ferromagnetic, but its high electrical conductivity allows changing magnetic flux to generate eddy currents inside the material. Those currents produce secondary magnetic fields that oppose the relative motion responsible for inducing them, creating electromagnetic drag and converting mechanical energy into heat. This is the operating principle behind eddy-current brakes used in trains, industrial machinery, and amusement rides. A rotating conductor can also produce a small electrical potential between its center and perimeter through the Faraday-disc effect, provided the magnetic field and electrical connections have the appropriate geometry. Such arrangements can operate as generators, but any useful electrical output must ultimately come from mechanical work supplied to the rotating system. Naing also examined Carr’s descriptions of blue-green illumination around the craft, noting that corona discharge could create visible light in sufficiently strong electric fields. At atmospheric pressure, air typically breaks down under fields on the order of 3,000 volts per millimeter, although actual discharge conditions depend strongly on electrode geometry and environmental conditions. A visible glow would therefore indicate electrical discharge, not necessarily propulsion.

Counter-rotation presented another distinctive feature of Carr’s proposed spacecraft. The OTC-X1 supposedly used major structural sections rotating in opposite directions, allowing the central passenger compartment to remain stationary while the surrounding machinery operated at high speed. Counter-rotating assemblies are entirely practical and appear in machinery ranging from turbines to coaxial-rotor helicopters. They can reduce net reaction torque and balance angular momentum, but they don’t automatically produce a net external force. In a closed system, accelerating one rotor in one direction produces a corresponding reaction on the rest of the assembly, while braking converts rotational energy into other forms, primarily heat. Carr’s descriptions reportedly included rotational speeds reaching 40,000 to 50,000 revolutions per minute, which would present extraordinary mechanical challenges at spacecraft scale. For comparison, a hypothetical rotor only 30 centimeters in diameter spinning at 40,000 RPM would have a peripheral velocity of approximately 630 meters per second and experience centripetal acceleration exceeding 250,000 times Earth’s gravity. Operating under those conditions would require exceptionally strong materials, precision balancing, reliable bearings, and substantial containment structures.

The most important unanswered question concerns how the machine would generate directional thrust. Carr described a control system containing twelve adjustable controls corresponding to the twelve perimeter electromagnets. Reducing power to one magnet while maintaining the others was supposedly sufficient to move the spacecraft in the selected direction. Naing finds the proposed control arrangement interesting because it describes a comparatively straightforward method of steering, but it doesn’t explain the physical mechanism responsible for acceleration. Magnetic attraction and repulsion between components inside a closed spacecraft cannot produce sustained net motion of the entire machine because the resulting internal forces balance. To accelerate, the vehicle must transfer momentum to something outside itself, whether that’s expelled propellant, surrounding air, an external electromagnetic field, or emitted radiation. Differential magnet control could redistribute forces and torques inside the OTC-X1, but without a demonstrated interaction with its surroundings, it cannot explain how the spacecraft would rise from the ground or travel through space.

The Utron: Bismuth, Electromagnetism, and Self-Charging Energy

At the heart of the OTC-X1 was Carr’s most unusual invention, a component he called the Utron Electrical Accumulator. The device consisted of two cones joined at their widest points, creating a symmetrical double-conical structure containing a hollow internal cavity. Carr described its geometry as both completely round and completely square, associating the shape with what he regarded as fundamental relationships between matter, energy, and space. The 1958 construction plans showed electrical windings extending from one conical tip across the central circumference toward the opposite tip, suggesting an arrangement intended to interact with the spacecraft’s magnetic fields. Carr claimed that the Utron could function as a source or accumulator of electrical energy and that smaller rotating Utrons would help recharge the central system. However, his documentation never established the winding configuration, electrical operating parameters, or energy-conversion mechanism with sufficient precision to support an unambiguous reconstruction.

Naing recreated the Utron geometry in two principal sizes, fabricating smaller units approximately 76 millimeters in diameter and a larger central component approximately 30 centimeters across. His decision to use bismuth for the larger Utron introduced an additional experimental variable. Carr had discussed bismuth in earlier writings, but Naing acknowledges that the surviving construction plans don’t explicitly require a bismuth Utron. Bismuth is particularly interesting because it’s among the most strongly diamagnetic metals, with a volume magnetic susceptibility of approximately negative 0.00017 under ordinary conditions. Diamagnetism causes a material to develop a weak magnetic response opposing an applied field, and sufficiently strong field gradients can even levitate small diamagnetic objects. However, the effect remains extremely weak in comparison with the forces produced by ferromagnetic materials and doesn’t constitute gravitational shielding. Bismuth also has practical manufacturing advantages, including a melting point near 271 degrees Celsius, a density of approximately 9.75 grams per cubic centimeter, and a tendency to expand slightly during solidification.

Fabricating the Utrons required substantial experimentation with casting techniques. Naing designed the conical geometry in SolidWorks, produced master forms using 3D printing, and created silicone molds capable of reproducing the hollow metal shapes. Molten bismuth was poured into prepared molds to produce individual cone sections, which could then be cleaned, assembled, and mounted around a central shaft. Photographs presented during his APEC lecture documented the manufacturing process from November 2024 onward, including larger castings produced using sand molds during March 2025. Smaller Utrons were wound with copper wire and mounted on metal shafts, with additional units completed during April and May. The finished components closely followed the general geometry described in Carr’s surviving plans, although Naing had to determine the dimensions, winding arrangements, construction materials, and electrical connections independently. The result was a collection of physical devices that could be examined experimentally rather than relying exclusively on Carr’s speculative descriptions.

The critical question is whether the rotating Utron can actually generate or recover useful electrical energy. In a conventional electrical generator, useful voltage can be produced when conductors move through magnetic fields or when the magnetic flux linked by a winding changes. A symmetrical coil rotating about its own axis in a similarly symmetrical magnetic field doesn’t necessarily experience such a change, meaning that rotation alone doesn’t guarantee electrical output. A solid conducting body may exhibit homopolar induction under suitable conditions, but extracting electrical power creates an opposing mechanical torque that must be supplied by an external energy source. Naing reported measuring only very small voltages from his Utron experiments, rather than the sustained energy production implied by Carr’s descriptions. The results don’t establish that every imaginable Utron configuration has been tested, but they demonstrate why the original claim requires more than a rotating magnetic assembly. Any proposed self-charging mechanism must account for the electrical energy delivered, mechanical energy consumed, resistive losses, and the source of any additional power.

Where the Physics Challenges the Flying-Saucer Claims

After examining the principal components, Naing’s investigation increasingly focused on the fundamental physical constraints that any successful OTC-X1 propulsion system would have to overcome. His October 24 presentation repeatedly distinguished Carr’s documented descriptions from established physics and his own hypotheses. The electromagnetic cores behaved according to conventional magnetic-circuit principles, the switching system exhibited normal inductive characteristics, and the metallic plates introduced predictable electrical and mechanical effects. The counter-rotating assemblies could exchange angular momentum without generating external thrust, while the Utron experiments provided no demonstrated mechanism for continuous energy production. Most importantly, Naing acknowledged that his prototypes hadn’t produced measured lift, thrust, or changes in weight. His findings don’t amount to an exhaustive test of every possible interpretation of Carr’s invention, but they identify specific problems that any proposed working version would need to solve.

To explore alternative possibilities for propulsion and steering, Naing examined the work of former NACA and NASA engineer Paul R. Hill, whose book Unconventional Flying Objects: A Scientific Analysis was published posthumously in 1995. Hill approached reported UFO behavior through engineering concepts involving force, acceleration, vehicle stability, and electromagnetic phenomena. One of the principles discussed in Naing’s presentation concerned the relationship between vehicle attitude and directional thrust. A spacecraft producing a force perpendicular to its body could accelerate horizontally by tilting, much like a helicopter. For a vehicle maintaining constant altitude, a 30-degree tilt would require approximately 15 percent more total thrust and could produce lateral acceleration of about 0.58 g. Increasing the tilt to 45 degrees could produce lateral acceleration of 1 g, but would require approximately 41 percent more thrust to maintain altitude. These relationships are straightforward consequences of vector mechanics, although they don’t explain how an unconventional spacecraft would generate the original propulsive force.

Naing also considered whether the OTC-X1’s electromagnetic architecture might have implications for gravitational engineering, particularly in relation to theoretical warp drives. In 1994, physicist Miguel Alcubierre published a mathematical solution to Einstein’s gravitational field equations describing a hypothetical region of spacetime that could travel relative to distant observers through expansion and contraction of the surrounding geometry. The spacecraft inside such a region wouldn’t need to accelerate locally beyond the speed of light, but the proposed spacetime configuration requires exotic stress-energy conditions, including negative energy densities that can’t be produced at useful scales by known technology. Naing explored whether an arrangement of twelve controlled electromagnets might provide directional control of a hypothetical warp field, using computer-generated animations to illustrate the idea. However, conventional magnetic energy and the stress-energy distributions associated with relativistic spacetime engineering are separated by enormous physical and technological challenges. His illustrations remain conceptual proposals rather than simulations demonstrating that an electromagnetic machine can create a warp bubble.

Some of Naing’s more speculative investigations explored possible relationships between unconventional propulsion and reported UFO phenomena, including crop circles and triangular aircraft. He considered whether a shaped bismuth element beneath a spacecraft could act as a magnetic mask, projecting a larger geometric pattern onto the ground. However, his own analysis found that localized magnetic field structures wouldn’t propagate like an optical image, with fine spatial patterns decaying too rapidly to produce the proposed effect at distances of tens of meters. He therefore acknowledged that this explanation failed its initial physical requirements. Naing also proposed that triangular UFO configurations might be interpreted as several circular propulsion systems integrated into a larger craft, potentially explaining reports of multiple lights. These ideas remain untested hypotheses without independent evidence connecting them to actual aircraft. Their inclusion nevertheless illustrates an important aspect of his approach: unusual ideas can be examined mathematically and experimentally, and an unsuccessful hypothesis can still reveal useful information about the constraints governing a proposed technology.

Turning a Historical Mystery Into a Measurable Experiment

The next phase of Project Vimana is focused less on constructing additional components and more on developing controlled experiments capable of measuring the machine’s actual performance. Naing proposes placing the operating assembly on a precision weighing system to determine whether energizing the electromagnets, changing switching patterns, or accelerating the rotors produces any repeatable change in apparent weight. He also plans to use force sensors to investigate whether the device interacts mechanically or electromagnetically with its surroundings. Such measurements will require careful experimental design because high-current electromagnetic equipment and rotating machinery can easily produce misleading force readings. Mechanical vibration, airflow, thermal expansion, magnetic attraction to nearby structures, and forces transmitted through electrical cables can all influence sensitive instruments. A reliable investigation would compare powered and unpowered conditions, use mechanically isolated and nonmagnetic test fixtures, characterize background interference, and determine whether any apparent force persists after ordinary explanations have been eliminated.

Other experiments will focus on the electrical and mechanical behavior of the individual subsystems. Naing wants to measure the actual capacitance between the aluminum plates, determining whether they provide useful energy storage or merely behave as isolated conductors. He also proposes comparing rotor spin-down times with the magnetic fields energized and de-energized, allowing electromagnetic braking effects to be distinguished from ordinary bearing friction and aerodynamic drag. Measuring the temperature rise of the plates could reveal how much energy is dissipated through induced currents, while oscilloscope recordings would characterize the timing and amplitude of switching pulses. Electrical power measurements must also distinguish real power from reactive power, especially given the low power factor observed during earlier testing. A comprehensive energy balance would measure power entering and leaving the apparatus while accounting for rotational kinetic energy, magnetic energy storage, electrical losses, mechanical friction, and heating. Without those measurements, neither excess-energy production nor unconventional propulsion can be established.

An important long-term opportunity is to transform the reconstruction into a reproducible engineering platform that other researchers can independently investigate. Carr’s original plans are historically valuable, but their missing technical specifications make faithful reconstruction difficult and leave considerable room for competing interpretations. Naing’s SolidWorks models, fabrication records, winding methods, electromagnetic simulations, and experimental measurements could eventually provide a far more complete technical description of the architecture. A documented replication package could include detailed mechanical drawings, bills of materials, coil winding counts, electrical schematics, magnetic core specifications, control software, operating procedures, and calibrated test data. Researchers could then compare alternative implementations, identify which results depend on specific engineering choices, and evaluate whether the system exhibits any behavior beyond conventional predictions. Even unsuccessful experiments would become more valuable because they would establish which arrangements were actually tested and what performance limits were observed.

The significance of Naing’s investigation ultimately extends beyond the question of whether Otis T. Carr invented a working flying saucer. The OTC-X1 occupies an unusual place in aerospace history, combining the extraordinary optimism of the early Space Age with technical claims that were never established through reproducible experimentation. More than sixty years later, Project Vimana is attempting to turn those claims into physical hardware whose operation can be measured rather than merely imagined. Naing hasn’t demonstrated anti-gravity propulsion, and several aspects of Carr’s proposed system appear inconsistent with established electromagnetic and mechanical principles. Nevertheless, reconstructing the device has historical and engineering value because it identifies what the original inventor actually described, exposes the missing information, and establishes a framework for controlled testing. Unconventional inventions don’t become scientifically meaningful simply because someone believes in them, but neither does skepticism substitute for careful analysis. Their value emerges when the hardware can be built, the claims can be defined, and the results can be independently measured. As Naing explained at the conclusion of his APEC presentation, the next step isn’t a bigger claim. It’s a measurement.
