RE: Question on throws
I personally think that getting the airplane to fly strait is just as important if not moreso then the throws. Make sure both elevator halves are in track with one another. Do the ailerons have equal throw? You would be suprised how many set up equal values on the TX between the Ail and flap channels (JR) and think they are getting the same throw both sides. Do the ailerons travel up just a tad more then they do down ( differential ) is the CG correct? With the CG correct does the airplane pitch to the belly when in knife edge? With propper CG the airplane should fly strait anywhere from 1/4-full throttle if it does but pulls to the belly or canopy on verticals then you need an engine thrust adjustment.
An airplane that is trimmed correctly will need less throw because you are needing less corrections. Take the time to learn to trim the airplane, make one adjustment at a time and do several flights with each adjustment before making more changes. It sounds like a big pain but your scores will reflect your efforts. Usually takes me around 50 flights before I am happy with a new airplane and my setups change with the sequence most cases.
