I dont mean to bore you guys with this probably simplistic problem but I am confusing
myself with this board. The autopilots were a gift from a friend and I can program it fine.
My radio is the Fut. 18MZ. I just use some DJI Flame Wheels for the basic structure
but I use regular 22 mm motors and some 10 Amp Speed opto controllers with BEC.
So a regular quad. But I have built three of them and the last two exhibit the same
problem. Roll is fine and correct. I loaded the 3.01 firmware from the Planner.
I do the compass calibration and it always comes out some large number in
the first digits like 195,-49,-13. or 199, -52,-19. That first digit is always over 150.
the Accelerometers are always good. Radio cal is good and I go out and fly and
it just flips over either forward or backward. Roll seems to be fine. You can see the
quad lift to the right or left based on the stick input. But I can NOT get it to pop up
straight. I put the 3.01 firmware and one with the 2.5 load and both do the same.
If I reverse the channel it still flips over, And you can see it coming by raising the
throttle . It must be a simple thing.
I usually build DJI stuff but I have had a blast doing the ArduCopter stuff, but
I just have to get past this simple issue. It might have to do with the Compass
cal, but I cant get to get that number. The hard part is I still have cable connected
and it keeps me from doing a smooth motion when rotating the quad. I have this
same problem with the 2.5 or with the 3.01 load. Thanks so very much for this
forum. A really great place to come learn!!!
