I've replaced the elevator servo now with a HT65 also. If I did a hard inside loop it would remain wanting to go down, but if I gave it a hard blip up it would fly level. So thats 2 brand new 3114s and I think 1 aileron servo is going the same way. Not returning to center. Either I got a bad batch of servos, they don't like 2.4, the brand new 607 rx is faulty, or the 7c is going south, or 3114s are not enough for this plane.
