I was wondering aloud what to do next. Right people overheard me and some time later i was handed 3D-scan of MIG21F13 as a payback about my services.
To make things harder i decide to built it in 2/7 scale and still make it weight under 20kg.

I will machine molds as fast as possible and try to make prototype flying asap. This is no commercial project and i don't care if only few parts can be produced. This is very much "having fun" project.

I tried to add picture of the scan from my computer, but i receive message, that i'm not allowed to add url? maybe later.
