Ok, you Airtronics Guru's out there.. a little help please!

I have an Airtroncs Quasar 6 channel radio, on FM channel 15.

Is this system compatible with the current Airtronics servos (or any other for that matter)? I have 5 94102'a in the box but they have a white signal wire where the newer ones have a blue signal wire. I seem to recall reading that there was a change in the compatibility of these servos from the original Quasar to the more modern RD's or whatever.. servos.

Is this radio compatible for use today (narrow band or whatever..)?

CGr.
