On Edge; I too had one of these for two years, before recently selling it. It is a fantastic flying airplane with the Saito 180 on it. I needed to add 6oz of weight to the nose to balance it. I am allergic to most glues, so I fly 95% ARF's. As with all ARF's, I tri-stock all formers up front, (or anywhere that looks suspect), added 1/4 ply to the landing gear area, and fiberglassed the motor mount area. With this plane, I even took the covering off the under side of the wing to inspect the inside. This only adds a couple oh hours to the build time, but is well worth it for the enjoyment you will get out of it. Many think this extra effort is against all that ARF's represent. To me, it prevents wings folding, tails falling off etc. If it looks like it should be beefed; beef it. The only other thing to remember, is that as great as it is, the Saito 180 uses 2oz+ of fuel per minute. 20oz = 10 min flight. Set your timer. See ya........
