I've got one coming with a spare 7 channel rx on the way. I'll let you guys know how it works in my Hitec pistol radio.
If you're tricky, you can hack it into any radio you want as long as you can find the power and PPM terminals. They even make a kit for it.

Reviews are amazing for this system as well. Tied with Hitec for the link it provides.
