RE: Airtronics / Sanwa MX3 FM 3 CH Radio Swap Program
Mine installed just fine without any problems. I plugged in some of my Airtronics, Hitec, XTM, CEN, and Traxxas servos just to check and had no problems with the connectors.
If you had gone out and boughten an MX3 radio from you LHS it would have came with the same RX.
As far as needing a " Z adapter" the radio does have a servo reversing option.
My only problem with the MX3 is the poor quality manual, which isn't CEN's fault.
