I am building a 108-2 kit made my Aeromodels. They went out of business about 20 years ago but you can still find the kits now and then on ebay. I just bought mine earlier this year on ebay. I am building a 108-3 and had to scratch build the tail. Here is a link to a thread where myself and someone else are building this kit.
