Thanks pigflyer ----
I've had on my mind for quite sometime a different Twin Sabre Dog, a turbo-prop powered one. It would follow along the lines of this project below. But because a swept-winged Twin Fuselage doesn't really look particularly good in my view, I would use a FJ-4 wing instead of the Sabre wing.
This project below though isn't for a turbo-prop (although it could quite well be), it's my idea for an ultimate 'piston-engine' powered aircraft.
The idea is it's powered by a Rolls Royce Crecy, not the V-12 that got built, but by a theoretical version of the engine that a Rolls Royce engine expert had theorized. It would have been a 24 cylinder 'X' configured engine of 39 litres and put out just over 8000 hp.
So a twinned fuselage version of below would make a pretty formidable attack plane in my opinion.
