The Quasar is an old transmitter. Where did you get it? (just wondering). But it should still work ok, but may require that you send it to Airtronics to get it serviced. Who knows how long it's been since it was serviced.

I have a Quasar, used it in England a few years ago (somewhat illegal because it was 72 MHz but they looked the other way). And, I was using it every weekend while I was over there and had no problems with it at all. I still have it, but don't use it any longer because I bought a newer RD8000 and now have the Spektrum DX7, which is, in my opinion, the Mercedes Benz of the RC radio world.
