2.2. Coaxial helicopters with two to four channels

This category includes such helicopters as the Hirobo XRB, the E-flight Blade CX, the Bladerunner II and the GPL Wild Wheels.

This type of helicopter has electronic stabilization circuitry, so you will not develop proper hovering skills. They also do not perform banked turns, so you will not develop forward flight turning skills. You can develop orientation skill with this type of helicopter, though.
