Sorry, I should have been a bit more specific.... I want to build one of these...
It's a Hillson bi mono built in the 1940's. Only one was ever built, and I cant find any plans so I would effectively be building a brand new aircraft. Steel tube construction, with a plywood cover.
Of course calling the LAA is the best place to start, but the person I need to talk to wasn't there yesterday, hence me asking here. I'll call them on Monday!
