In my father's collection I found one of the rarest rubber powered kits ever produced. It is a Sikorsky XR-5 heli new in the box. The kit is complete and in perfect condition. The box has a couple of tape marks and a piece of tape or two. It has a rotor span of 26". The rubber strand has dried up but the rest is still wrapped in the brown paper. Does anyone have an idea of what it is worth? I will probably put it on fleabay unless I get an offer I can't resist. I have chatted with the "Stick and Tissue" bunch and there is some interest there. It is rare enough to keep but I need some new R/C stuff(don't we all?)so I will sell it. Let me know if anyone knows anything about it. Thanks.
