Please set your throws as to the instructions...too much throw and the airplane will be too sensitive....you can always change it later if you want...
you set the offset on your throws by having the servo arm at something other than 90 degress to the servo...if you have 1 aileron servo....use a star shaped servo horn...cut the arms off of the horn except for the 2 that would be the bottom of the star.... now you have 2 horns that can't be 90 degrees to the servo...mount the the horn so that the 2 arms are equal on the servo and point to the leading edge of the wing...hook up the pushrods
Good Luck
