Thanks for the detailed answers. I think I will reinforce the firewall while I am at it and hit the landing gear area with some epoxy. Sounds like the 2 screws for the lower wing control horns are not a problem. I removed the screws and wicked in some thin CA per the instructions, so I will consider it good.

I should have it ready to go for this coming Sunday. I am going to get a few flights in before I add smoke.
