The World’s Smallest Co-Axial Helicopter

 Just move along people. Nothing practical here.

GEN H-4 is the world’s smallest co-axial helicopter. It features four GEN125 engines that produce 40hp @ 6800-7500rpm and a shock absorbent aluminum frame. Weighing 155-pounds (empty), this vehicle has a maximum cruising speed of 55MPH. Unfortunately, it will set you back a hefty $35,000. Videos after the jump.
