Like I said, "the 4-1
receiver would be useless". The original question was if the stock Spektrum transmitter would work with the stock 4-1 receiver. Like you said, you have to cut out the receiver side of the 4-1, so it is not longer a "stock" 4-1.
That is good information, though. I like the idea of the Spektrum system, no glitches and no antenna coiled up around the skids.
Said all along you had to hack into the 4-in-1, but three outa four ain't useless.
wildjones--the O-rng I think you're talking about is the little piece of fuel tubing that holds the TR on. No o-rings on the motor. Just screw it in and resolder the wires and you should be good to go. You may have to reset the proportional on the 4-in-1. Try it and see if it tries to turn on you and then adjust accordingly if needed.
