RE: Ryobi 31cc engine setup
The packs in my 7CAP is brand new and my SkySport 4 is about 4 years old. I bought all my recievers on channel 38, so Im sure all of them are on the same band. For my CAP I ordered two 1600mah batteries for the RC setup, so those shouldent be bad (I have not receved them yet though). Ill let you know more when I hear from Futaba.
