I am also planning to build one, but I can't start to build until one week later.
I have quickly created a cockpit for installation into the Becker model. Anyone interested can get it here:
pyro-cockpit.pdf (7,32 MB) - uploaded.net
I normally don't like to use photos as textures, but in this case I made an exception, because it fits in with the 3d-graphics style of the model.
sjsquirrel, could you make the medium lifter available in pdf-format?
