Avadi lists the MA-250 at 15.8 horsepower at 3,700 rpm (11.8 kW at the same speed). That is the manufacturer’s published specification, not an independently verified production-engine rating: an SEC-archived offering memorandum described the MA-250 as a prototype under development and unavailable for commercial use.
Avadi MA-250 horsepower and other published specifications
Avadi’s official overview lists these figures for the MA-250:
| Measure | Avadi-published figure | Rating point or context |
|---|---|---|
| Power | 15.8 hp (11.8 kW) | 3,700 rpm |
| Torque | 22.3 ft-lb (30.24 Nm) | 3,500 rpm |
| Engine weight | 23.6 lb (10.7 kg) | Manufacturer overview |
| Brake thermal efficiency | 42.12% | Manufacturer overview |
The power and torque figures are specified at different engine speeds, so they should not be treated as measurements taken at the same rpm. Avadi presents all four values as specifications; the sources cited here do not establish them through an independent test report. Avadi MA-250 overview
What kind of engine is the MA-250?
Avadi describes the MA-250 as a single-cylinder, four-stroke gas engine with a rotating-piston design. In the company’s description, the piston connects to two counter-rotating, self-balancing connecting rods. Their scissor-like motion converts the piston stroke into rotation without a traditional crankshaft-based powertrain. Avadi also says the arrangement reduces side pressure against the cylinder wall and uses rotational motion to eliminate a traditional camshaft-driven valve train. These are the manufacturer’s design claims, not independently validated comparative findings. Avadi MA-250 overview

Is the 15.8-hp rating independently verified?
The available sources do not provide a dated independent dyno report confirming the 15.8-hp figure. An SEC-archived offering memorandum described the MA-250 as a prototype under development and not available for commercial use at the time covered by that document. It includes company claims about testing and intended uses, but does not supply an independent test report for the rating. SEC-archived offering memorandum
Avadi’s overview also carries a testimonial attributed to Rick Paya, identified there as president of RPM Racing Engines, which refers to dyno testing and rounds the output to 16 hp. For the precise answer, the specification list is clearer: it states 15.8 hp at 3,700 rpm. The testimonial is not a substitute for a published, independently documented test report.

What applications does Avadi identify?
Avadi lists portable power generation, UAVs, agricultural and industrial equipment, motorcycles, and light-sport aircraft as potential applications. Those are proposed uses, not evidence that the engine is certified, deployed, or on sale for any of those markets. The offering memorandum’s prototype status description is the relevant qualification for commercial availability at the time it covers.
