Sprucemoose,
You said that you are building a TF .60 Corsair, you might look at the TF giant scale P-47. The ones that I have seen fly look great. The kit and a G-62 which is what the ones I seen were powered with, and the retracts should come out around a thousand. Pica has a P-40 that is around 85" set up for a 1.8 cid (30cc). A Spitfire also makes a good flying plane. Just something about those eliptical wings that make them fly so good!
