Thanks for all the inputs. for the next build I'll go full deflection, but for now ( I should of have posted this earlier) what I did was go with the manufacturers specs and kept the tightest gap. The (really small). With the manufacturers spec I have free movement. Does this sound correct? ailerons (3/8"), elevator (1/2") and rudder (1") this would be for a Extra 300 .46 size 58" wingspan. Would these measurements give full flight ability for the plane?
Thanks,
Pat
