I found a potential issue with the mono mod w/ stir sticks. The wing loading that is achieved is trying to pull the wing off. Since there is a solid connection between the body and the middle of the wing, the wing is trying to get loose at the root. A small amount of tape may solve this, I don't know yet. The wing supports are cut at 3 1/4" which fits comfortably between the original spar slot and the lower wing slot. I'm not trying to give the wing a higher profile. Although I might do that later. Amusing flight feat of the day, I got the plane inverted, flying forward, and the wind hovered it and then deposited it in my truck bed. It dropped almost straight down, 5', with motors at full power. Tim
