Sorry Gunny taking so long to respond. The flaps leave about 1/8" at the T/Edge of the wing. This has not been an issue.

What will be an issue is all the !#@$#@ oil that blows on the left side of the fuse. I have the mufflers pointing straight down but the swirling air from the props really paste the oil on the left side of the fuse. from the leading edge of the wing back to the rear door. It takes quite a bit of paper towels to clean it all up. (I use Bounty). Any one else flying yet. I am rained in today. 100% chance of rain and 40 degrees. Eventhough I am ready to test fly there is no good weather forecast for the next week. UGH. [:'(]
