In our club we are about 50/50 JR and Airtronics. There are two that fly Futaba. I am a long time Airtronics flier and dealer but am exploring the new Graupner radios. They seem to be a great value and have some great telemetry features built in and others by add on sensors. Want a vario? buy a $35.00 sensor and plug an ear phone into your TX and you are ready to go.
