Ok I am looking at a Hangar 9 Ultra Stick as a second plane. I want to set it up with quad flaps. That way I have room to grow still within the plane. But, I need to have some suggestions about a radio. I have a JR Quatro with my Alpha Trainer and I know that it will work for the US for the time, but I am kinda wondering if I should go with a 4, 6, or 8 channel radio to take full advantage of the quad flaps. Let me know what you guys/gals thing. (Oh Im open to engine suggestions too)

Thanks
Cole
