Just a quick tip to extend the life of the wings. Consider sealing the leading edge with packaging tape. After flying into a brach for the first time with this swing and mashing up the leading edge, I did this. I rubbed the leading edge with high proof rubbing alcohol to clean them first. Surely there was a change in COG, however minimal.. but I did not notice it when flying, so my guess is the CPU manages the extra weight. I then proceeded to hit branches and crash twice, and could find no damage.
