I have some slightly used aircraft parts; i.e. Airmaster hub, rotary
engines, etc. I'm sure there's an opinion or two out there on where's
the best place to list these items for homebuilders to find them. Ebay
is obvious, but doesn't really cater to this audience. Other
suggestions?

Ebay is a Lousy choice!

I know of a classic aircraft, in beautiful shape, that barely got any
bids on ebay. This occurred within the last two months. Ebay is for
run-of-the-mill stuff.

EAA Aport Aviation, EAA Vintage, Trade-A-Plane are where you will find
the likely buyers.
