I built the Corsair and I love it. It will probably take more time than the P-47 due to the gull wing. It flies great, probably very similar to the P-47, so I say pick whichever one you like better. The Corsair has more of a reputation for being difficult to fly, but I have not had a problem and I have only been flying for 1 year.

I use a YS 91 because I wanted good power but I didn't want too much sticking out of the cowling. It is perfect for it.
