PRANDTL

This is our version of the famous PRANDTL wing project developed by NASA,  Armstrong Chief Scientist Al Bowers challenged the fundamental core assumptions of leaders in the field of aviation. He began his multiple-year trek to prove that not only could adverse yaw be overcome, but it could be turned into proverse yaw for aircraft, without relying on rudders or complicated computerized flight controls to accomplish it - just as birds achieve it (read more). You can chose between 3 differents canopies depending on the type of flight that you wanna make: Pure glider, motor glide or motor glider with FPV camera. We provide you the option of towing the plane by installing a simple an effective release system.
