I just had my boat rigged with the ultrex, the last thing I need to do is the calibration. I also have the different hand set but as you explained it's the same as yours. You are the first one who has indicated that so glad to hear that information. Will follow your instructions because it's more simple than what I heard so far. Damn shame the information doesn't come with the trailing motor. If it weren't for youtube I don't see anyway one could set their equipment up correctly. Much appreciated. Pickwick here I come!!!
