I am new and have read a lot, just got mine on May 7th, and have already had some learned lessons (aka mistakes) However, I have a persistent pain, When I take off, it always pitches backward with the stick at center. I have tried the wiki self calibration of the controller and it never completes. Then I do the software calibration while the copter is connected to the computer and the screen is fine, and it still pitches instead of straight up at take off. Of course in GPS mode, Jump up, hover, and then go, GPS takes over, but still needs corrections to hold a real steady flight, letting go of the controls might let it wander. Mostly it goes aft like it wants to at take off, but sometimes it will wander left also or both at the same time, coming close to run away without stick input. In any IOC mode, it wanders way to much, take off requires pitch always. How can I get this into calibration?
