Still flying my lil banchee. I didn't like the rearward CG, I don't think planes should climb when they're inverted. I removed some wood and covering forward of the battery tray and rebuilt the area with stick balsa. I then lengthened the battery tray using ply of the same thickness that was on the plane originally. I have been able to place my packs about an inch further forward than before and now the CG is just right.
