Is any marketing this item?  Or maybe having a selloff of unused bits?

             Paul, these are becoming more difficult to source.  I collaborated with the west coast guys a few years back and purchased through Yuvenko. However, there's Alberto at Hobby Club located in Cali. It might be worth asking. He currently or maybe I missed them, isn't showing 1/2A props. He was carrying the green with the carbon laid into the center. They were a bit pricier vs the standard glass props Yuvenko was selling by a little more than a dollar.

Thanks.
Thus far I haven't found a current access to Russian, Ukrainian or Czech products.
I have ordered an assortment of APC's to try & make do.

Mike Hazel of ZZ Props is making a couple of fiberglass props that are for the HP 1/2A's in combat.  His are $8 ea.  I bought a few of them but haven't had a chance to test fly yet.  They look good and should work similar to the green ones I like.

I think Yaro might still have some of the blue props left for sale.  Maybe 20 or 25 the last time I heard which was 2 or 3 months ago.  I don't like those but others feel they work great.  A lot of RPM but not much speed.

For low cost new purchases we are more or less limited to rubber ducky's.  Those are the Cox black plastic props now supplied by Cox International.  Cut them down and folks feel they work fine.  I haven't had the same luck using them.

Three months or more ago I tried to get APC to make another run of the 4.6x3's but they wouldn't even if I ordered 250.  I asked how many were needed to make another run and was told they would get back to me.  Haven't heard back from them.

Over time I figure one of the Ukraine/Russian folks will be making them again but it will likely be awhile.
