Hello kit guys and especially the Old Timers without whom we would all be left scratching our heads! I fell into this airplane a few months ago and couldn't pass it up even though I've never done a foam wing build. I have the fuselage and a set of foam wing cores. The original wing was destroyed in a hangar accident I'm told so I need to build a wing. I know this to be a Dave Bridi creation but I can't seem to find any instructions on how to build this particular wing. I don't intend to do any more than just enjoy seeing this plane fly so I think I would like to have flaps so I can land at our local club field. If anyone can steer me in the right direction I'd be grateful. Thanks, Steve

It's a Bridi 1/4 scale Cosmic Wind. If you have new wing cores already it should be a simple process to finish them off. You may want to do a search on how to sheet foam wings. In this case if it were mine, I would sheet them with 3/32 balsa using epoxy and a vacuum bag setup. I would add a 1/4"X12" ply jointer and glass the center with 3 layers of 4 oz cloth then cover the entire wing with 3/4 oz cloth, prime and paint.

There was at one time a racing class for these using 1.20 4 strokes. I would go with a YS 1.20 as this would be the right amount of power and enough weight for correct CG.

Hi speed, this fuselage measures 71.5 inches from the back of the spinner to the rudder hinge line. I have learned from another forum that this might not be the 1/4 scale but more along the lines of 1/2.35 Thanks for the build info, I can use all the help I can get.
