If i was going to start a company my first plane would be a F4U Corsair in 1:48 or 1:32 and then 1:48 or 1:32 Fw190A...
Don't worry i would still make a P-61 Black Widow as the 3rd release...

I like this era the best....
I would stay within the WWII range for a few years then move up to the modern aircrafts of the world.
May even try some WWI fighters in 1:32 range as well.I know am dreaming again it aint ever going to happened.
