Well, this thread has pretty much run its course. Because of the way I tallied votes, giving a person's vote to the first plane they mentioned unless a clearly stated preference for another, and the way some aircraft, particularly the B-17s E and F and the P-38s F and H, it is likely the the effective lead would be the P-38H with 7 or 8 votes. The Ki-100 and Yak-3 barely qualify as variants, and in fact may not by HTC's estimations, both did well with 6 and 4 votes respectively. The Bf109G-14/AS and, probably, B-17F tied for third with 5 votes each. Obviously something like the Fw190F-8/U1 would be a lot cheaper in terms of work time for HTC than would a variant with significant differences such as the Ki-100.

Brownien, the TBD Devastator is not a variant of an existing airframe in AH. Also, you already gave a vote on the first page.
Scotty55OEFVet, I understand it to be the replacing of the two 12.7mm guns with two 20mm cannons and an engine change that would have slightly more power and perhaps a higher critical altitude.
