Help with recoil mechanics

[Meter rat]

you only have this problem with this plate? are you sure that the servo is working properly? without forgetting the advice of Mr.Bix (shunt on CN 6) test the servo on another TX / RX set, a servo tester is very useful in this case, absolutely nothing happens when connecting? servo? for example with the turntable under power, should hear a slight noise or see a possible movement of the control arm, as Mr. Bix says, must be something simple, hence the need to do all kinds of tests, before deducting general failure? I hope I didn't confuse too much

Servo has been tested on a different TX and RX, and by plugging it into the gun lifting port,CN8?, and goes through its full range. So I know the servo works. The only thing I have not tried is a jumper lead in CN6, which will be a job for later.

Thank you everyone for all your help.
Now all working. All it needed was a jumper lead in CN6.
