Love it! I just bought the Classic Airframes kit, now I have to decide what markings to do - you give me too many choices......!
I just finished a great book called Interceptor Fighters of the RAF 1935-45 by Michael Bowyer, which details the development of the Whirlwind. He says that Petter made a mistake in wanting the smallest possible airframe because then it was tied to the Peregrine. If he had made the airframe a bit bigger, and used the Merlin, there would have been greater potential for development - and perhaps the Mosquito would not have been needed!! There was a proposal in 1940 to use the Whirlwind as a PR aircraft instead of the Spitfire, but nothing came of it - that would be an interesting profile!
