The old airtronics servos will not even work with a new airtronics rx. The old style had pos and neg reversed...or something like that. You can re-wire them to work with standard equipment of any brand. Just make sure the signal, positive and negative match-up and you will be fine.

People still fly on AM, but it's rare, at least in CA....I have an old AM tx and 2 AM rx's and I will likely never use them.


If those old servos work well and are already set-up and installed, just re-wire the connectors and shave-off any plastic that interferes with plugging them CORRECTLY into your Futaba rx and go fly.
