There have been lots in the past, but I am not aware of any current jet kits on the market. I know of several jet engine home built airplanes that are flying today. The most famous one is the Bede 5J, that was used in a James Bond movie. You can find this airplane on the internet. This was built from a kit designed and sold by Jom Bede. There was also a propeller version of this grunge
tees kit that was sold in the 70′s. Sadly Jim was a brilliant designer but he was a poor businessman. He began delivering the kits but soon went bankrupt. Many of the people who had paid deposits lost their money and never got their kits. It was sad because the BD 5 was as really neat single seat airplane. Pretty and VERY FAST!
