My radio (transmitter) is a Futaba Skyport Digital Proportional T4YBF and the reciever is a JR RS6UL 6-Channel Negative Shift. There is a note on the box in white letters stating "Negative Shift- for use with Futaba & Hitec transmitters" well I have a futaba transmitter so that leads me to believe they should work together ya? I hope some people have somethin to say about this because im bummed out right now!
