The Spektrum radio operates on an entirely different frequency band, so the 4-1 reciever would be useless.
Couldn't stand it any more. had to do the research. Yes!! You can fly the blade with a positive shift radio. You can use the 4-in-1 but have to remove the Rx half and replace the Rx with a positive shift. This basicly makes it a 3-in-1 which will handle the esc, motors and gyro. The add-on RX will handle the servos. If you're not comfortable with a soldering iron, don't attempt it. It requires opening the 4-in-1, removing the stock RX, and soldering in the positive shift RX. I did a search for "4-in-1 to positive shift" and it came up in another forum. The post didn't have any details, just said you can do it. The post was from an E-flight rep.
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.
