[Jas]

Have you tried the OS esc to see if it does the same thing?

As soon as I lifted off, I’d hit the switch we always used to use for retracts which put me in my “Flight Condition”. My flight condition was pretty much the same as my takeoff condition except the throttle trim was moved up to the point where it would just barely have the prop turning over. At that point, the brake is inactive and you’ll have instant throttle response with your stick. I also had a “Brake Condition” assigned to a switch so I could have the brake active for certain maneuvers like the stall with the 4-point down. For that condition, the trim is all the way back down to where it needs to be to initialize the controller.

I've used outrunners and Pletty Advances with both Castle and OS ESCs and never had this problem before.  Never had an inrunner before.  What am I missing?
