I really like this video. It appears that this young man hands off the camera to his little brother and then demonstrates formidable flying skill. He reports that he made the front weight from scrap copper wire. I now advise people to start with the Jagwing because the Baby Bug is more complex; but this young person got it right--perhaps an aerospace engineer in the making!
