Mr Cox

I didn't want to alter the cowl before I had desided on the orientation of the engine. Turns out it works just fine inverted so now I'll start to make some went holes in the cowl.

I would really like to keep the spring starter though, they are so convenient to have, but the stock one will not fit inside the cowl.
I have a few ideas and might try to make something similar to the later springs from cox which are not grabbing the prop it self but rather the thrust plate.
