| I have both a DX7 and a 9C with Spektrum module.
I bought the DX7 when I switched to 2.4GHz and find it a totally adequate radio for all my uses. I like the fact that it has 20 model memories and the model match is handy. Battery life is great on the stock battery. My only complaints are the lack of a throttle stick activated timer and the funky throttle kill feature where you have to hold the throttle down trim button until it hits the end of travel.
I really missed the throttle stick timer so I bought a Spektrum module and installed it in my 9C. I HATE the way they did the antenna connector.... a real kludge. I eventually drilled through the back of the module and module pocket and ran the cable internally. After installing a CX2 antenna in place of the collapsible one, it looks totally factory installed. However, I found that I missed the much faster control response from the DX7 vs. the 9C more than I missed the lack of a stick timer so I am now back to using the DX7 exclusively. It is quite noticeable, especially on smaller helis.
If you do get the DX7, do NOT use the Futaba charger. The connector is the same on the DX7 but the polarity is reversed.

. Having looked at the module based system for the 9C I have found out that it has a slower response time than the DX7 technolgy. I didn't realise that although the module upgrade transmitts on 2.4GHz it is confined to the orginal PCM 1024 system, and doesn't transmitt the packets of data the same way as the DX7 DMS2 technology.
good luck with your new Radio.
