Solved My elevator control jiggles

[Jo's squadron]

So I built a Bushwacker yesterday, when I plug in my battery everything works but sometimes when I plug it in the elevator dose not move.
And when it dose move the elevator jiggles (just dose a super fast little movement) randomly.
I tried turning my TX on after I plugged the battery but it dose not help. Running it on Spectrum.
I will try with my FlySky later today.

Any idea what is happening?

Thanks in advance for the replies.

Loose wire / socket in the elevator servo plug?

 

[Mr Man]

Yeah, check all of your servo wires, and if nothing there, test the same port with a different servo, if that servo works, then you’ve narrowed it down to a failed servo. If the new servo didn’t work, try plugging it in a different port and see from there.
