Here is a set of plans that I am making extensive use of to scratch build the engine and other parts. The last 3 are actually instructions to put together a Russian made plastic model kit that I found on the web. Useful insofar as it lays out the basic order of construction. The Bleriot model in those instructions appears to be a later version used in WWI although the differences are rather subtle. Mainly the auxiliary fuel tank in the boom (which I plan to omit).
I would like to come up with a way to do all that lovely rigging inside the boom. Getting the thread inside is going to be hell though!
