Correction of poor clearance between wing trailing edge and right hand aileron
After closing the right hand aileron leading edge it was noticed the clearance of this leading edge and the trailing edge of the wing dropped to a low value of 1-2mm when the aileron was deflected fully downwards. This is caused partly by the rev 0 aileron skin bulging forward more than the rev 1 left hand skin. Recall that I needed to shim the right hand aileron balance tube because of this slightly bulged outer shape.
The other contributor to the cause was that the trailing edge dipped down a little owing the manufacture tolerance of the support channel.
The fix was to create shims which lifted the trailing edge slightly, improving the clearance to a uniform 5mm over the full movement of the aileron. This clearance was now very similar to that of the left hand aileron

Shims made from 0.63mm 6061-T6, after priming. Note also I have inserted an extra rivet right at the end to positively tie the skin down to the flange of the aileron rib at this point, in imitation of the rivet that is present in the rev 1 left hand aileron skin
