If I'm reading correctly, the Tornado engine was about the same power and weight as a Sabre II - and a little longer and slimmer. A later version would have more power - just like with the Sabre.
If you go with contraprops, something prettier would please me more. Like on Seafire 47 and Seafang.
Radiators.... Yes it will need some. Clearly, the P-51 style works. Perhaps something like that could be done without making everybody say that it looks like a P-51 radiator?
(once you get a little outside these experts' circles (
) anything with a doghouse radiator looks like a P-51D, and any jet with intake below the fuselage looks like an F-16)
