Another B400 Problem
 

After replacing all my servos on my b400 to hi tecs i have now found another problem

I centered my tail servo no problem.

When the gyro has initialised my rudder control does not act how it should, i give rudder one way and tail servo returns to center, i give opposite rudder and upon releasing the stick it creeps back to near center but never gets there.

When i spool up the head i get yaw, if i counteract this the heli spins wildly out of control. If i reduce throttle the same thing happens, tail spins and spins

I am wondering if its not actually the servos but the gyro ?

You may have to reverse your Gyro?

From inside the transmitter program you mean ?

Mine did the same thing, I switched my Servos to Spekturm, you have to reverse the Rudder control IN THE TRANSMITTER, and reverse the GYRO ON THE HELI. Once I did that mine flew no issues.

Go to the "REVERSE" menu on you TX, and select RUDD then reverse the thro of the servo. On the Heli the Switch on the the top of the Gyro I beleve, Simply thro the switch to the other position. Do this powered down. Power back up and all should be good.
