This equated to a 3 degree increase on my Stabila digital level.
IN regards to being aligned with the wings. Not sure where to reference.
Should the top of the flaps when retracted (full up) be perfectly level with the top of the wing? (which has a bit of a dip in the last foot of airfoil)
when I lay a 4 ft level across the aileron and flap,, and I pull the aileron to match the bottom of the level, the leading edge of the aileron is high enough that the level does not touch the wing for about a foot, with the gap under it better than a 1/4 inch at the trailing edge of the wing.
I dont have the blueprints for this craft btw, the builder passed away before I got them..about two weeks after I bought it. I have the builders manual, the builders photo log, and the aircraft logs..still hoping the widow finds the prints.
the method I used was to measure with a scale from the aft edge of the flap to a rivet line on the wing. make both sides the same. crude but effective. a friend advised me of this method after several unsuccessful attempts to correct the heavy wing.
RV-9A, Tip-up, Superior O-320, roller lifters, 160HP, WW 200RV, dual impulse slick mags, oil pressure = 65 psi, EGT = 1300F, flight hours = 600+ for all
Simplicity is the art in design.
