MDR 208 Engine

The MDR 208 engine is specially designed and developed for medium and large unmanned aerial vehicles. Compared with the traditional AR731/741 rotary engine, its combustion chamber is designed with ceramic plating, which not only prolongs the service life and reliability, but also greatly reduces the maintenance and repair costs.

Since there are few use cases of UAV rotary engines in China, we have a special person responsible for teaching how to use, maintain and repair. It enables users to get started as soon as possible and get rid of technical bottlenecks.
The MDR208 engine has highest power to weight ratio of any rotary engine in the world. It has been specifically designed and developed to be the ultimate engine for small target drones and short-life UAVs.
