Hey guys I just put together a flying wing. I have a couple question one is with my elevator is very sensitive and needs only about 1/2 " travel to work very well but I need more roll out of the plane. Should I move my cg forward a bit more? This plane is built for RC combat (not slope combat). It has a 64" span and 12.02 MAC. I have it balanced at 2.5".

Thanks:
