no im full aware of the afects of a tail rotor type helicopter in the tendency to hover right side low its the actual swashplate thats not level i can make is level using the links fron servos to swash and when every thing is ready to go looks good and when the batt is done ill see the swash un level once again
im using trim to keep it level ill give you my controler settings if its any help to my problem but if its normal well then thats what its is but just wana know if it is
but i do apreciate any help from you pro's thanx

My Belt-CP and My Blade-400 both seem to do this. Basically I believe its a center of gravity issue. When I change batteries on either of them (1800 vs 2200) the weight changes and I have to change elevator trim. End result is the swash is never truly level, both have a little tilt in elevator.

Only way to fix it would be to re-arrange the mass of the chopper so its balanced about the main shaft.

The swash plate leveling tool for the trex will work if you have one, and yes I've tried it and it works perfect.

Maybe this will help. Its from the trex forum but if you watch the video on pitch and throttle curves it will help give you a better understanding on how to set it up. As for a swash leveling tool I have the trueblood swash leveling tool for a trex 450.
Oh, and I love my blade 400 too!
