CoAX 2D

First Ultralight Helicopter with German Type Certificate

EDM AEROTEC uses the D -Motor Ultralight Engine 

Compared to the single rotor helicopter, the coaxial rotor variant with four rotor blades on two inversely rotating planes creates a more stable flight behaviour due to its inherent stability.

Since no loss is caused by an additional tail rotor, the entire power of the engine is used for lift.

They use aviation-approved materials in the UL area to ensure a higher reliability of material and technology.

CoAX 2D   

With the revision of the original prototype a new concept has been created in practically all essential points, which is also reflected in the change of our type designation.


Each, the frame, the landing gear, the rotormast, the cabin and the tail boom are milestones in the development and form the basis for our quality requirements with their optimised manufacturing and improved properties.
