yeah I am going to try my sr3000 with two basic servos and see if the issue occurs, what sucks is the receiver is brand new I only used it for a few hours and saw the issue, and then I got out of r/c for a while so now its a discontinued receiver and horizonhobby wants money to possibly fix a new receiver.
The odd part is I have two SR3000 receivers one is like 5 years old and works great the other was like 3 years old and has the issue, it has to be a production defect.
