RE: g2 head speed
Yes, the same linkage adjust blade tracking and pitch. If you're just into hovering and straight flying, I have my blade pitch at -2 no throttle, +3 at midstick, and +10 at full throttle. For 3D, obviously the pitch range must change drastically. One other thing, check to see if your feathering shaft is bent (you have to disassemble the head to get to it). Then, check your ESC if the helo is powering down like you said. You may need to reprogram it.
