I recently bought a QR-1 to replace my dying v939 quadcopter. After flying to QR-1 for a few flights, I am noticing that it limits the angle that the quad can tilt at, even in advanced mode. It is very annoying because whenever I try to fly fast I have to slow down over a long period of time because I can't make quick maneuvers. Is this a problem with my quad or do they all limit the angle of the quad during normal flight, even in advanced mode? It didn't say anything about this in the description on the Traxxas site.
