RE: Spektrum 2.4 module in my 9CAP ?
The 9C is a pretty old radio buy today's standards. It's a decent radio but the electronics industry has evolved so quickly that today's transmitters are way better. I'll probably buy a new transmitter every couple years. I currently have the 10CAG. It's native 2.4G. No module, no antenna sticking out from the back. It's a nice radio but they are getting better every day. The 8FG with 14 channels and assignable servo channels is pretty amazing for the price. Futaba shocked me with that one. My buddy is about to get one.
For foamies my 9C with Spektrum module is awesome. I have never had a radio glitch in 2 years. For large gas planes it's FASST only.
