It's weird. Even if I don't know the specific type, there are usually features that are a dead giveaway. That vertical tail is classic Curtiss, or possibly Republic. And it's obviously pre-war. From there, it's pretty easy.
You see the weight and climb rate of this thing? It's a frigging butterfly.
Yeah, it kind of reminded me of the Model 299 at first glance (the tail, I mean)... I am not good with most of the really obscure stuff myself, but I still love trying... end up learning a lot in the process.
Just looked up the weight/climb rate... man you ain't kiddin... neat plane. Had no idea these were better climbers than even the Ki-43!
I wonder how different things would have been had they had them in numbers back then.
