Need help PLUG-In wing spars
 

Hi, Anyone know how to set up plug-in wing spars? Dr. Charles sent them to me without instructions. Anyone willing to photograph their set of instructions for me?

Pretty straight forward, bolt the receivers to your formers and then glue the blades into the wings (hole ends go in the wing).

Looks much like the setup Byron used in the day. Assuming the spars are going into a foam wing, you want a ply box structure to capsulate the spars and spread the load through the foam wing. This box structure will be epoxied into the wing and the spars glued into the boxes. The spar receptacles will need to be bolted to corresponding internal plywood bulkheads that line up with the wing spars. The screws in the bag thread into the spar receptacles and tighten against the actual spar thereby trapping the spar.
