What do you think of this?
We are all familiar with the Polikarpov Rata (I-16). To get the CG where the designer wanted it, the radial engine was set somewhat back right against the leading edge of the wing. Suppose they had moved the engine back about a foot to a foot and a half (30 - 46 cm), and then mated the Pratt & Whitney R-1820. It might have been right against the wing leading edge. To counter the added weight, perhaps they could have a wing root leading edge kink, sort of like the kink in the P-51 wing that accommodated the undercarriage. In this case though, it would have been to add a bit of wing area.
Any takers? Do any of you think the P&W would have helped the Buffalo, had it been tried?

Brewster had originally proposed using the P&W the same as Grumman but the Navy said no and to use the Wright engine while Grumman was allowed to use the P&W.
