Yeah i notice that as well but when i switched to the zeal frame it flies fine. The next frame is going to be the rakon just waitingon frank to get it inI fly my Q500 alot with out GPS. I have no problem even in winds (5-10 mph) I spent many hours on none GPS quads before buying the Typhoon 500 so this is a cake walk to me. I do find it wants to goes backwards a lot more without GPS so I have learnt to compensate for that on take off.
Hope you guys get this taken care of.
