GRU COPTER - A Study in RC Helicopter
Using the principles of RC Helicopter; built a GRU COPTER using various pre-built components. The remotely controlled helicopter that has two blades runs on the same axis in opposite direction. The "co-ax", as it's generally known, employs dual electric motors (one for each rotor) and a fairly sophisticated electronic control system. It's within the electronics that the helicopter's rotation is stabilized, and the main motors are synchronized in order to maintain the excellent stability these helicopters are known for.
