The Airtronics RD 6000 Super is an awesome radio! CCPM compatible 90, 120 and 180, 5 pt. throttle and pitch curves, 4 flight modes, remote gyro control, throttle cut off etc. etc. etc. Just a great quality radio with just about everything most people will ever need, I know I won't ever need another radio, and it's under $300. and has worked out flawlessly for me thus far.
