Burnt-out throttle channel in Optima-6 receiver
I have an Omega 1.8M electric sailplane. It has about about 65 flights on it with an Optima 6 receiver. No problems at all, but I put in a new motor - Hyperion 2213-14 - and it wouldn't run - just shake. The servos still moved. I replaced the speed control - same behavior.
Then the receiver stopped coming on. I then jiggled the wire from the ESC to Ch3 and the receiver would flash on and off. And yes, the connector was fully inserted into the slot.
I then tested the same ESC and motor with a new Optima 6 receiver - binding to the same model memory in my Aurora - and everything works fine.
My conclusion is that the throttle/BEC channel in the other receiver burned-out or for some other reason malfunctioned.
Does that sound right? Is this common? Is there something that could have caused this such as using a servo extension between the ESC and the receiver?

not all plugs on ESC have the same internal dimensions
