Those 3 1/2'' H-9 wheels that you mentioned: are they the ones for the NEW Mustang? The older H-9 warbird wheels ( the ones that come with Corsair, Hellcat, and others) are 3 1/4'', which are too small for any '60 size warbird.
Jock,
The 3 1/2" H9 wheels I have on my Hellcat are out of the 1.50 size P-51 ARF. The 1.50 size P-47 came with the same wheels as well. I know a lot of guys, myself included, modified the P-47 to take a much bigger wheel and threw the stock units in the "spares" box so an add in the classifieds section might find you a couple of sets. The Hangar 9 web site has a 3 1/2" warbird wheel listed but says it won't be in stock until late December.
I wonder if the 4" Dave Brown tire could be cut down and fitted to his 3 1/2" wheel?
