I finished up the right aileron this afternoon. The trailing edge of the left aileron turned out fine, but having learned a few things, the right aileron turned out very good in comparison. The last item for the ailerons is to attach the brackets on each end that then get bolted to the brackets on the wing. I am waiting on Amazon to deliver a single 3/16" bit so I can drill the bolt holes and finish though. I have normal length 3/16" bits, but they are too short and the chuck of the drill can't clear the end ribs.
