Sayha - X FPV Race Frame

Quadcopter frame based on the Impulse RC Alien and Lumenier QAV-R with center X removable arms. Its available in various sizes supporting 4", 5" and 6" propellers. Its light and super stiff if printed in ABS 100% infill.

Included are all the .STL files for all the models. The frame is quite light and stiff. I threw the frame over and over against a wall and from a 5th floor balcony and it survived perfectly.

If you end up building one.. let me know your feedback!

Cheers!
