Where can we get tube and tire for a Russia?

Check out the Russia Sailplanes Yahoo Group. (Albeit I havn't gone there in a while since Yahoo Groups has become a rather painful environment.) When I needed to replace the tire on my Russia I was told there to use the same tire that goes on a 1-26. The width of that tire at the hub hole seemed way too narrow for the (metal) hub on my (prototype) Russia AC4a, but after inflation it worked out. For a tube, after some misadventures with smaller ones, I went for a larger one (I'd have to look up the size code at home), since it gets stretched so far near the hub. Also, for my hub at least, I needed a tube with an angle stem, PLUS a stem extender. Warning: check your tire pressure (with a gauge) every couple of months, since it can get low but still look OK. With sub-optimal pressure, hard braking can result in enough rotation between the tire and hub to shear the stem of the tube.
