Rory,
You've received some good answers, but I'll reinforce the "get help" topic. I fly electrics too, but glow is a completely different animal. (Unless you're flying 10 to 15 pound electrics.) And many warbirds, which may include the Zirolli Corsair, are the nastiest "glow" or "gas" planes out there.

Be sure that the guy you find to help you has large warbird experience! The local club instructor may have flown nothing but sport planes, and may not be much better off than you when it comes to flying that thing.

Just my opinion.
