Thanks all! I hope Art will post. I had heard of the control reversal - is it only apparent at slow speeds (someone actually suggested you should set them up reversed but that goes against the grain)? I always intended to use heaps (about 80%) rudder mixing and have made sure the full flying rudder gives me lots of deflection. I shall probably post a link to utube or some of the mechanism work (and link it to here). Anyway I'll keep you all informed!
