CH - do a search - there was quite a long thread on this very subject. I think the final outcome was either lube the parts well or a bad jittering servo.
Looks to me that all three servos are mixed in to perform collective pitch. Seems the only way to see which one is screwd up is to see if it jitters with no power? Or what, disconnect the engine from the board and move things around? I can see through this crap and this could be a sweet flyer if it did not have a few issues here.
I found this but seems a bit extreme for a low end helicopter but makes a bit of sense. Logic says just to keep fooling with this thing and it'll all straighten out on the next bird!
gave up on the NiHM and brushed motor after the second crash or so, just junk. With the Park 370 motor, ESC, LiPo 1320 battery and a HH gyro, my AXE hovers rock solid. I literally went from not even being able to contain it in my parking garage to landing on the top of an upside down 5 gallon bucket in one flight. ALL THE DIFFERENCE IN THE WORLD. The problem with the AXE and Blade CP, is the low inertia, low speed rotor system. If you get that rotor moving 80% faster as I did the AXE is quite the stable flying machine.
