Guys, I was thinking of building a 1/8th scale Hellcat in the (hopefully not too distant) future, too, and now I've received from Chad his homegrown canopy and gear doors.
Gotta say,
they look (and feel 
) terrific! Today I posted some pics of them in the CMP Hellcat thread:

And kudos to Chad for this spearheading this very attractive group build idea.
