There was a toy when I was young that I cannot find. It was dark blue, roughly 5" x 3", it was a vought F4u Corsair that transformed into a robot or something. It was heavy for its size and had some yellow on it. I looked at most of transformer brand and didn't find it. I'm thinking it came out in the mid eighties or slightly after that. The wings folded up and the propeller part swung to the other end of the toy. I really would love any help on this.

Could be from M.A.S.K. One of the Venom guys was a blue corvette
