RE: hover issues
Disconnect ur motor then turn the transmitter on and plug the battery in.
Wait for the tail servo to initialise then put the throttle at half way,
now the blades need to be at 0 pitch (flat) use a pitch guage to get it close as possible,
put the throttle back down, unplug the battery
plug the motor back in then the battery again and now you have to get the blade tracking right then your should be right.
use the adjustable knobs on the tranmitter to give it a little more pitch, i put it at about 3 o clock on both of them to give it a lilttle more pitch so the battery last longer.
hope this helps
