Ive always run a Airtronics Sport blazer AM 27mhz [X(] in my cat and never have had a problem *knock on wood*. Even ran it in my gas mono and never once had the failsafe kick in.
Like said...i go for simplicity with fuction when getting a radio. Currently ive been running the Hitec Aggressor FM 75mhz with no problems what so ever. Going to switch to the Hitec CRX only because i want to be able to use the same radio for all 3 boats

All for under $150
