If it is the newer version with dual aileron servos... you can just build it stock. IMO the fuse is a little weak to lighten much... unlike the H9 CAP. Just don't add any unnecessary weight. Use a minimum amount of light ply to get your gear in and use light gear. CF wing tube from DA, 3.5" Sullivan Skylight wheels, lightened backplate on the spinner or better yet, a CF spinner from Pierre. Every little bit helps. This plane has more of a tendency to come out tail heavy that nose heavy... so pull/pull will work out fine. It also is more forgiving tail heavy than the CAP. Plan on about 27-lbs on an accurate scale with the BME-102.
