The result is a prototype Hoverbike that seats a single pilot on a Kevlar reinforced carbon fiber with foam core frame in between two horizontal spinning propellers constructed from Tasmanian Oak with a carbon fiber leading edge. Instead of the complicated swash plate setup found in single rotor helicopters, the Hoverbike employs the same basic flying principles as a tandem-rotor Chinook helicopter. As with the Chinook, the counter-rotating rotors cancel out each other's torque reaction, eliminating the need for an anti-torque vertical tail rotor and increasing the efficiency of the vehicle.
Quite interesting as a concept until an accident if the rider falls through the blades, although there are protective covers around the blades. Can try to make a model of this.
