I had the opposite problem with frame rate.I went lipo conversion in a nitro truck but use the TEKNO clutch so I need a servo for brakes. With the 9000T in steering & 9100s in throttle slots in reciever & frame rate set at 5.5ms everything is good.When I put the same 9100s in the aux slot in the reciever & made the aux the slave to throttle channel the servo would slam all the way full brake & then go limp & you could move the servo horn by hand. The guy that figured out the problem didnt know why but when frame rate is switched to 11ms the aux channel worked propperly. I couldnt find anything in manual or on line,maybe some kind of program bug?
