I use a 9CAP. I also have two. Just in case I have a failure during flying season I can go to the other one. I have all 6 planes programmed into the radio exactly the same. If one radio goes down I'm ready with the other one.

Chief Aircraft will sell the 9CAP as transmitter only. If you catch one of their specials you can get it for $289. Then you can use your existing receiver and servos and purchase what servos you want.

Thanks
Barry
