straffo,
I can sympathise with your problem. I like the P-47 and always wondered how such a successfull plane in RL is such a cr@p in every flight sim I played. and how "unknown" planes like the La7 and N1k turn out to be the real hot rods of WWII.
The reasons are based on real world conditions usually not factored in to the sims. The P-47 IS inferior to most WWII fighters if you fight it on the deck, but take it to 25k and it's another story. The La7 really was a hotrod, but it's use was EXTREMELY limited by it's range.
In the case of the typhoon, it was not meant to waste fuel on "grabbing alt". In the "seek and destroy" missions it's famed for, it didn't carry heavy payload, it carried mainly rockets/small bombs and the 4 cannons. And operated from fields close to the front. The RAF had the mossie for strikes, typhoon for close support.
HTC is trying to insert another factor into the simmulation and this one turns out to be the bane of the hotrods. the cost of having a plane that out-accelerates everything and reaches close to 400 mph in the weeds, is a ridiculously short flight time. So now you have to choose, preformance or endurance. Fly around at 400mph or slow down to conserve fuel.
The fuel porkage will be limited as pyro stated, so the only remaining issue is the exact fuel multiplier. too much, and some planes will be unplayable. too little and the hotrods will loose their only disadvantage. I agree that 2 is "on the edge" for some planes. 1.5-2 is the acceptable range IMO.
