How to make Tumblewing (Urdu Video)
Tumblewing
A tumblewing is a paper airplane which rotates about a horizonal axis. Its mode of flight is more akin to confetti than traditional fixed wing aircraft; However, several model aircraft have been built with tumbling wings for lift (force). Because it has no need for ballast, the tumblewing design has a lower wing loading and makes a good walkalong glider which is easy to make and fly.
