I need help. I am building the H 9 P 51. 1-- The manual shows aileron servo in the star decal which would put the aileron control horn 3.5 in in on the aileron. mine is on the white part of decal so the mounting slot puts the servo and control horn about 2 in in. Also the retract servo is too low about 1/8 and the rods bind on the wheel wells. Do you add an extra servo mounting plate? Any Help Thanks so much joe
