The world's first model rotary engine for 1/3 scale model aircraft is now available from us
Only a rotary motor sounds like a rotary motor


* Smooth running that can only be compared with an electric drive.
* High torque
* Very easy to regulate via the carburettor
* Cylinder made of finest grey cast iron. (No flaking of the coating possible)
The ignition can be operated directly with two Lipo cells or 3 LiFe cells thanks to the integrated voltage converter and undervoltage protection
* Our motors are designed with the latest 3D-CAD and are equipped with a 4-axis
CNC milling machine, CNC lathe and conventional machine tools.
* Last but not least; over 20 years of experience in designing and building model four-stroke motors
