Thunderbolt P47 - Have you tried setting up ailevators? A 9C transmitter or equivalent will allow you to slave each elevator half to the same side aileron. I was sceptical until I tried it, thinking that the small span of the elevator would reduce it's effectiveness in roll. However, probably because of slipstream effect close in to the fuselage, I found that it makes a significant difference. It also results in much greater roll control availability when hovering. I am assuming that you have maxed out your aileron travel, all the way to the mechanical limit. have fun flying.
