RE: Pattern TX
Also, the "9C" is a PCM 1024 TX. The receiver you choose is what determines the 9CA"F" or 9CA"P" part, the TX will do both it just depends if you wanna pay a little more for the PCM RX like 149DP as opposed to the cheaper 127 if you get a combo.
I got my combo from Chief Aircraft a couple years ago and they had great deals and options!
I have used the JR 8103, and the JR 10X and I just assume use my 9C anyway---
Cheers!
