. One of these two seems to have a problem every other week. I have gone through 6 or 7 hitec HD extensions in this way.
I am using 9CAP with 2.4ghz TM8 module and futaba s3010 servos everywhere except throttle.
Sat up late at night and get everything working. And now, this morning, the other servo is doing the same.
I am considering putting in Muldental extensions instead of Hitec now. Will need to replace only the aileron ones as the ones on elevator and rudder have leads soldered (instructor did that in initial setup). Any idea what my problem is and whether the Muldental ones are good enough?

It could be that you are getting corrosion on the connector terminals: Low cost extension leads most likely will be using tin flashed connections. These can suffer electrolytic corrosion through being in contact with dissimilar metals. If you are using 3 extensions per servo, I'd suggest making up your own leads with soldered connections at the servo with 22AWG minimum UL1007 wire to a high quality connector in the model. It doesn't need to be a Futaba standard servo connector, any 3 pin connector will do, but |'d recommend gold plated pins for the connector that is mated and un-mated a lot.
It could be the effect of cement dust if you store in a garage. "Death to Chrome" can get anywhere and start dissolving away.
It could be "black wire corrosion" if you left your battery connected in storage.
It could be congealed engine gunge in the switch?
