I'm working on a few micro-goonies right now. I'm doing the Zoom Broom, Cloud Hopper, Micro-Broadsword, and a Galaxy Guppy. I also installed a micro engine mount in a Mosquito that I threw together. Semroc sells the laser cut fin set for the Mosquito. I know, I know, why not just cut them out myself. Well, I was buying some other stuff from Semroc and the laser cut set was about a buck, what the heck. I'm using decals from Excelsior and supplies from Fliskits, and Semroc. I bought some 1/32 and 1/64 birch plywood for the fins. The 1/32 was used on the Micro-Broadsword and the 1/64 is going on the goonies. The 1/64 stuff is surprisingly rigid when cut out small like that. It was expensive but will do a gazillion goonies.
