Is the Gee Bee you are talking about a R1 or R2 ? because I was looking for the GB that GP used to sell and I cant find it anywhere. If memory serves it was a 60. size model made of fiberglass fuse and built up wings. The one your you are refering to here someone posted that it has a 66in. WS and you are talking about gas engines for power. This must be something new and I am Interested.please let me know and in the meantime I will search GP again. Thank you. Eric
