Would you have pictures of lowering or raising the aileron with the help of washers..?
thank you

Igor: I don't have pictures showing the Aileron hinges but it is quite
easy and simple to do. You need to measure the discrepancy in height of
the Aileron with reference to the top of the wing by laying a long
straight edge along the top of the wing down over trailing edge of the
Aileron. You may need to hold the straight just outboard or inboard
along the outboard or inboard edge of the Aileron IF the Aileron is
higher than the straight edge You will see that the the top of the wing
is flat and not rounded as it comes down to the Aileron. Hold the
Aileron parallel to the straight edge and measure the difference in
height which could be above the straight edge or below the straight
edge. This will tell you how much to raise or lower each hinge of the
Aileron. Make note of this.
Remove the Aileron and Rivet a 3/16" STEEL fender washer (small hole
same diameter as the #10 bolts and a big outside diameter) to the OUT
SIDE of each hinge arm using 2 #3 rivets with the 3/16" washer center
hole moved either up or down from the original hinge holes the amount
each end of the Aileron was above or below the wing surface as noted above.
The hinge arms are made of STEEL not ALUMINUM. Don't use a piece of
ALUMINUM. Its hole will wear out with time.
Then using the washer hole as a guide drill through each hinge arm.
You will now have the Aileron moved up or down in the hinge arms to make
the Aileron top surface match the top surface of the wing. This is
proper Aileron alignment to assure minimal drag and avoid a "Heavy Wing"
Reinstall the Aileron using the original 3/16" bolts (hinge pins) and
check the other clearances and measurements I noted in my "Wing Mounting
and Rigging" and Vans instructions. You will have a nice flying FAST
airplane.
Note: You will have to clamp the washers to the hinge arms SECURELY
so they can't possible move when you drill the rivet holes to rivet the
washers on the hinge arms. I would recommend a couple of small Vise
Grip pliers and an extra hand or Vise to hold things. Good Luck Doc
