That's a neat biplane Villa.

Anyhow, i'll leave the wing alone, did some thinking about
moving the wing and it'll make more sense to plan on using standoffs.

I'm going with using standoffs for the engine, because
I was lucky to find some nylon round stock to make the standoffs with.
I'll get the measurement with some all thread and then drill the nylon stock
so the allthread will have something around it to strengthen it.
