Yes, the F8F is a beast and would be able to pwn just about anything else flying here now. That said, it is rather short legged as it was designed for the fleet interceptor role. Once you dump off all those external tanks and get into a fight, you'd better keep your eye on the fuel gauge. Frankly, introducing another perked plane into the game probably wouldn't do much - we don't see hordes of F4U-4s running around, and that is definitely the hottest thing you can take off a deck right now.
I'd rather hitech spend the time getting all the rides we have now up to spec - it is frankly embarrassing to have the spits and typhoons with a nice cockpit while the tempest looks like it does. Once that is done I'd like to see a couple more axis rides (maybe a J2M and Fiat G.55) so that the FSO's get a little more varied.
