For my first build, I decided to get it into the air as soon as possible, so no paintings, no carbon reinforcements, and no dihedral adjustments to the wings and the stabilizer. I applied the stickers for the colors and as a cheap way to stiffen the surfaces.
The plane ends up very nose heavy. I had to add 20 grams of tail weight for balance. In hindsight, I should not place the battery so forward. Maybe I should have run it on a single-cell lipo.
Because of the incidence reduction, its GC is about 1 cm aft of the original position. The pitch is still stable with this new incidence-CG combination. Don't know how the flight compares with the original configuration.
All up weight, including the 20 grams of tail weight, is 133 gram. (The original 5 gram nose weight has been removed.)
It needs more than 10 mph of wind to fly. It penetrates ok, and gets small very fast, maybe due to the weight. It prefers to make wide, smooth turns, like a jet, again this maybe also due to its high wing loading. I think it should be lighten up.
It tends to wave its wings. I think removing the wing dihedral not only makes it look more scale, but will also improve the flight performance.
