Okay, I'm back. Been doing some thinking on the wing mounting. How does the single dowel in front hold up over time. Do you think it would be worth the effort to do a double dowel setup to help keep everything snug through the years.
Also I am thinking about replacing the back metal wing mount bolts with 1/4'' plastic. That would be less prone to loosen due to vibration wouldn't it. But I don't know if plastic bolts would be strong enough on this plane. What is everyones opinion on this.

The single dowel works just fine so no need to do any adjustments in that area. As for replacing the metal wing retaining bolts with nylon, that's a very good idea and one which I did several years ago, after having the metal bolts loosen up on during a flight. I used the regular 1/4x 20 nylon wing bolts which have worked fine, just added a small piece of 3/8" thick hardwood to each hole area to give a deeper threaded hole for the nylon bolts to have more bite.
