I have a Futaba TM 7 module in my 9C and I use it to fly my Boomerang out of 6 or 7
flights it has worked well. I may up grade to the TM 8 as that was what I had originaly
wanted but it took Futaba almost a year to get them to market.

On the all radios im aware of you have to be in the ppm mode for the 2.4 to work thus
I can only get eight channels out of my 9C at the most with a 2.4 module.

I already had the boomerang set up in the 9C with a Futaba PCM receiver so it was just
matter of popping in the 2.4 module and replaceing the reciver all my previous programs
stayed the same.
