I agree about that part but at the same time it doesn't really make it plug and play anymore. I'm going to try my hand at some channel mixing to get the cannon to fire on one of the toggles on the RX9 to fire the cannon. Of course for the amount of work that i did end up doing I wonder if it would ave been smarter to go with a system that takes all the functions and gets rid of the RX-18 al togeher. It's not that i don't like it but I think in the end I probably should have gotten a system that just replaces everything. Ohh well gues we either keep plugging away with the BARC4 or get another system.
