I think a WiP would be a nice idea. Personally, I don't think these large aircraft type specific GB's do as well as the smaller types, Me 109's, P-51's etc. There is a 1/48th B-17 GB that's open ended, the host hasn't been around for a long time and it is a bit quiet, but there still some stuff going on in there.

Would be nice to see your being built up though Ken, would defiantly follow a WiP.
