Howdy, netters; I thought I posted this a day or two ago but it never showed up (I think). If it did- sorry for the repeat. If not- here it is again: I have a 6" semi-pneumatic tailwheel on my M-19 "Flying Squirrel" (not yet flown). 'Semi-pneumatic' means that the tire is hollow but doesn't have a valve stem for filling. It relies on the tire compound stiffness for shock absorption. Pictures are the last two at http://www.flysquirrel.net/gear/gear.html and the tire is a standard catalogued item from W.W. Grainger. (I believe it's the $25 unit at http://www.grainger.com/Grainger/productdetail.jsp?xi=xi&ItemId=1611763914&ccitem= ). The tailspring is the Aircraft Spruce "homebuilder" single-leaf, modified to receive the pivot which is welded on.
I have the unit in my garage so if anyone is interested in the axle dimensions, weights, or other details- let me know and I'll get that. In the meantime, I stand ready to box this up and ship it to any KRNetter who is flying or taxi testing and is interested in trying it out. No charge. I will point out that going to a larger diameter tailwheel will have a slight effect on your landing configuration and speed if you have a taildragger, because you won't be able to get as much angle of attack on the wing while on the ground. Probably not a factor, but a consideration.
