John,
I have a Zenoah G-62 in my TF GS Corsair that I just love and I have a 3W70iUS for a YA P-40. They are both terrific engines, the G-62 was a lot cheaper though. For the $ I would say the G-62 was my favorite with the Moki 2.10 a close second. The Moki powered P-51 seems to be a bit faster too.

Thanks for the input! What about a DA 50 or the DL 50? Then I would be very tempted to use the constant speed prop setup from [link=http://www.warbirdpropdrives.com/]
