Let me be one to tell you some items I know. I just built this plane per the manual. Flaps.. Nope None. But there is a nice thread on this site that showes them being added. It's in the Miss America thread. That's where you can find several things.

The stock landing gear was less than impressive. I installed the robart mechanicals. First flight I discovered that robart did not flat spot the gear and they pivioted. Just fixed this no big deal. The wing does need material removed with the robarts. The advantage of them is the thicker steel rod landing gear over the original.
