Pic looks good.

(I hope the inside repair job looks as good...

)
I have bolted a .049 on the nose of one of the foamies... had to chop the nse off flush, and epoxy on a 1/8 inch ply firewall. The .049 was a bit much... and had no throttle. That was a wild ride! .020 would be a bit light... I doubt the thing would climb at all. (I have one... should I try it?

I just bought 2 of the new "Virtually indestructable" {maybe

} foamies... new type of styro.)
