I am trying to install control horns on my ailerons with difficulty.
Everything is lined up on the ailerons with the last hole protrouding out of the aileron hinge line.
The problem is when I marked and drill the holes I cannot seem to get the hole to come out in the right place on the top of the aileron.
It looks like I'm lined up when drilling.
Is there some sort of trick to doing what should normally be an easy task?
Included is a pic of the control horns.
