Aileron Hinge
Although it seems to work trouble free, I was not
happy with the flexibility in the MKIII aileron hinge. The whole
assembly could be made to move at the tip due to hinge bend. My
cure is to use some stainless L hinges identical to the ones that
secure the front edge of the horizontal stab, and attach them
to the outboard end of the aileron, and the rear spar. The hinge
pivot distance is identical to the piano hinges. Use an AN-3 bolt
with locknut for the pivot. After the aileron hinges are on, position
the stainless L hinges temporarily using hose clamps, pivot and
adjust until everything is smooth and aligned, then mark the holes,
use 3/16" stainless rivits. It's RIGID!
But you still need to install the aileron counterweights:
it is not unusual for Kolb's to have their ailerons buzz at speeds
over 85 mph.
