I would vote for the P-47. As Dannost said, the Corsair wing is much more difficult to build, and other factors are:

1) The Thunderbolt, even without using flaps, will fly in almost at a glide, unless you build it way too heavy.

2) The Thunderbolt, "Jug", will allow a much larger engine to fit inside the generous cowl, with minimal alteration, if scale appearance is important to you.

For the TF Gold Edition model, I think you will be happiest with a 4-stroke engine of the .90 size for thrilling ,scale-like sound and performance.

Just my opinions.
