Servo stutter

Hello everybody.

Me and my friend are trying to setup my T-Rex 600 with the APM 2.5 but we are having problems with the servos for roll and nick stuttering, but there is no issues when moving the Collective pitch. 

We have tried numerous things like, two BEC's, playing with reciever frame rate, different reciever/transmitter, older APM firmware, digital/analog servos ect. But it seem like the problem comes from the APM itself. 

What could be the problem? and what could fix this?

    I cannot imagine the heli flying well with this issue. 

  • Okay, so the stuttering is normal?

  • that's ok, just let it go
