hurricane 425 need help!

[jc318]

OK so I am using airtronics rd8000 its a little older setup but it works. I took it out of my raptor 50 after drive belt broke. My issue is on throttle up only one rotor moves for pitch? This is my receiver setup..

CH 1-elevator
2-aileron
3-throttle
4-ruddet/gyro
5-gyro sens
6-cp

I have looking from rear left side front servo as aileron. Right side goes to CP. Rear top is to elevator. All links look good. I don't understand why only one rotor moves with throttle up? Also on throttle up only one servo moves witch is the CP servo? I have read and read on what I'm doing wrong with no luck..please help!

Unfortunately, I am not familiar with Airtronics radios, but there might be some things to try so we can see what might be wrong. What happens when you move the cyclic stick? Does only one servo still move or do they all move? If they all move then it must be something in the radio programming for the pitch. If only one servo moves with the cyclic stick, then it could be bad servos or receiver. If only one servo moves, try plugging the servos into different channels and see if the problem follows the servo or the receiver channel.
