Yes. I followed the manual step-by-step. Remember the up-down thruster and airleron are on the same channel, hard wired together by a Y connector. I don't think that this is a question of a mix. They're physically connected. I can only assume that the Y connector is bad, or there's a problem with one or both of the servos. I also notice that only one leg of the Y connector seems to be a problem. That is, if I plug the thruster and airleron into the connector, one of them doesn't work. If I reverse the thruster and airleron in the Y connectors, the other doesn't work. I'm going into the shop now, and I'll reverse both Y connectors from left to right, to see if the problem goes to the opposite side of the plane. Very frustrating. Thanks
