This is a paper model for a concept WWII biplane for WWII. It had a contra-rotating propeller and large top wing.
Quite the Paper crafting skills there.
Truth be told, I recycled some parts: The vertical stabilizer and top wing are from a P-39 aircobra kit and the main body is from a Me-109. Wheel struts are sratch-built and contra-rotating propeller actually works... Use it to see if wind is blowing from the AC-duct.
