HEY ZIMBO! Some guys have fun converting those cheap styrofoam " drug store" gliders to RC with either electric, or .061 pwer. Foam compatible CA glue or EPOXY works on this stuff, as well as any wood glue. You can create your own control surfaces by slicing the foam with a razor knife and putting a bevel on the flap with a sanding sponge.Use EZ hinges cut in half lengthwise. Control horns can be made out of circuit board material,or 1/16" plywood, or even plastic if you roughen it up before gluing. Make the push rods out of 1/16" welding rod with a V shaped kink in the wire to make adjustments with. Push the servos into undersized holes cut in the foam with a dab of CA glue. The foam has to be fuel proofed with water based poly urethane paint. Believe it or not the SR71 "drug store" glider makes a pretty good one to fool around with! Have fun!
