Hi, it's Alishanmao, and welcome to my channel! My Old Bi Copter Tilt Rotor Dual copter is still flying very well. Though I do not use its GPS features anymore because it's always glitching. I always fly my Z1 Bi rotor in manual or altitude hold mode. This is absolutely a fun VTOL Tilt rotor RC Bi Rotor aircraft. Enjoy the flight and don’t forget to comment.
