RE: Cor-Star 60 Version 2.0 plans and pics
Let's start on the fuse!
Take your 1/4 aircraft ply (not lite-ply) and make a firewall. If you already have an engine and motor mount picked out, you can drill the holes for it at this time. It's easier to do it now than when it is on the rest of the frame. Use the thrust line measurement. The cennter of the prop should be on the thrust line. A 1/8 inch or so off shouldn't effect anything, as long as it is centered in the firewall side to side.
