RE: pos and neg shift???
An FM (or PCM) RX operates on a basic carier frequency. The frequency is then "shifted" from that frequency to encode the signal information. It doesn't say anywhere on the RX shich way it shifts. Some shift pos and some neg and some will go either way, either automatically or via jumper programming. A given manufacturer is usually consistant in having ALL of his products shift in the same direction or both.

maktec - Airtronics and JR radios use positive shift. Futaba and Hitec radios use negative shift.
So, which one you need depends solely on what brand of FM Transmitter you are using.

I found a JR ad where this had been available as EITHER positive OR negative shift depending upon what you ordered. They did not mention being able to convert it and I doubt that you can or they would have mentioned such a beneficial feature.
