I need some opinions here. I have a dream 110 that I have installed 2 jr9011 servos for the elevators in the rear and I am having a problem with them. I am running one extension each to the receiver and have them mixed. I am using a Futaba 9Z with a r149dp pcm receiver. When I first turn the aircraft on with the Tx on the two servos have a lot of buzzing and there is no power output to either servo. I can push both servo's down away from neutral and soon as the get through about 30% travel they snap to life. No play no buzzing no nothing. They act perfectly. I have moved the elevator over a hundred times and no problems. If I turn the airplane off and then back on agian the whole thing starts over again. Any suggestions where I should start. Has anyone had this happen to them before.

Thanks,

Pete
