RE: Black Magic VF3 E build thread!
A note on honey combing. I don't do it because I think you save as much weight vacuum bagging. It lets you get away with using less epoxy, and still get a good, if not better bond. The problem I have always seen with honycomb is that you have to use a thicker film of resin to insure good contact accross the joint. Added to that is the fact the you are gluing a sizeable amount of sheeting to air.
Something I have considered trying is sheeting the wing with vaccum, as I have done in the past, then using a dremel to cut out ''rib bays'' afterward. I don't know how much effect this would have on stiffness. It would definatly be lighter. I think that if I used 1/2'' thick ''ribs'' in a truss pattern (like they use in powered free flight) it should be all right. Has anyone tried this?
Pardon the sketch, it was a quickie.
