Here's the Pegasus in large scale [1/3700] put out by Fantastic Plastic. It was patterned by Alfred Wong and he does outstanding work. It has over 100 pieces and is 20'' long and 7'' wide when assembled.

The kit is very nice to put together. It's detailed nicely and needs very little putty, it has the usual resin issues but easily fixed. It took me a week and a half of constant work, when I could to finish it. It's a little pricey but worth it at $230. I recommend buying this one if you can.
