Greebo, do you know which plans he used? At first glance it seems like a Ziroli plan, but I am not sure of Ziroli's wingspan. Has to be near 100". I would think that he would have scratch built considering he wants a scale master, this means using Hawker's plans scaled down.
It looks very good, especially considering he did not use fiberglass. 2 cylinder in line is an interesting choice which will give it a more authentic sound. What exhaust system is he using? For something such as this, I would hope Keleo (or some other exhaust co.) would build him a custom, accurate exhaust.
Flying warbirds has a stigma, but we warbird flyers cheat with airplanes like Typhoons, FW 190s, P-47s, F6Fs, etc. This is cheating because they are very stable at low speeds and have very wide landing gear. I have 4 different sizes and powered Bf 109's and I am telling you, the difference is shocking. A Spitfire has very similar tendencies to a Bf 109, so I know exactly what you mean. I am positive that a Typhoon would be joy to fly, especially a large one like this.
Would love to know more, thanks for sharing.
