Ok i just installed all new servos on my 400. ds 285 and a ds290g and a g270 gyro.Now am i correct in saying that you have to reverse all of them with the exception of the throttle and rudder? And also my rudder won't center when you neutralize the stick is this normal when it is sitting still but then it will also do it when it is spun up.Thanks

You have to check the control direction, merely replacing them doesn't mean you have to reverse them.

With a heading hold gyro it wont recenter the tail servo like a normal channel while its sitting on the bench.

Thanks thats what I thought but being new to the sport u never know.I never read where somebody had to reverse a different servo that they had installed butI figured that was the case.</p>

I'm just saying check it first, if you were to say switch a futaba out with a hitec then yes you'd have to reverse the channel. It just depends on how the servo's are wired inside.

Thanks up here in northern montana there isn't to many heli drivers so I thank all of you on these forums for the advice and knowledge.Also are the set up degres for the main rotor the same when you are in 3D versus normal mode?

I do because I don't like the helicopter jumping around when changing flight modes, also in an emergency I don't have to think about any switch flipping

could somebody pm me with a phone number so I could talk to a person about reversing these servos insteads of tying up a forum thanks
