RtS Lugnuts wings actually become the arms of the robot.

I'm also thinking about HftD Terradive, where the wings form the sides of his lower legs. Mould reused for DotM Space Case, TFCC 2013 Incentive Figure Depth Charge, and Botcon 2013 Machine Wars Starscream.
Terradive is also excellent but again the wings do just fold out of the way, rather than becoming a functional part of the robot mode. very good approximation to the Russion Su-47 I think.
