OK, progress of sorts, I think. 1) Tx 22 in program mode, that is fine. 2) Rx 41d-22-v5 in program mode, seems to be Ok but...( I'll come back to that in a sec) 3) Tried to set it to 3,2,1,1, but not sure that it has actually accepted it. 4) Connect everything up, and motor runs fine and sound is on...
