Original helicopter "classes" were based on the engine size. For example, a helicopter with a 0.30 cu in (4.9 cm 3) engine was a 30 class and a helicopter with a 0.90 cu in (14.7 cm 3) engine was referred to as a 90 class helicopter. The bigger and more powerful the engine, the larger the main rotor blade that it can turn and hence the bigger ...
Weighing a mere 10 grams, the Picoo Z measures 170 mm long, and has a main rotor span of 130 mm. The helicopter is controlled by a 3-frequency a-b-c infrared controller, with two channels (one for the main rotor and one for the tail rotor) allowing independent user control of throttle (main rotor RPM) and tail rotor RPM.
Cyclic/collective pitch mixing (CCPM) is a control concept employed in collective pitch radio-controlled helicopters. [1] CCPM reduces mechanical complexity and increases precision of control of the helicopter rotor's swashplate. Unlike conventional systems in which a single actuator is responsible for a single axis, CCPM mechanisms allow ...
The Mattel VertiBird helicopter flies around a central base containing an electric motor, spring lift assist, pitch control, batteries, and a throttle.A 21-inch arm with pitch control rod and the spindle that transfers the power to helicopter via drive springs and drive rod, is connected from the central base to the helicopter.

Unmanned, remote control or optionally piloted variant An intermeshing-rotor helicopter (or synchropter ) is a helicopter with a set of two main rotors turning in opposite directions, with each rotor mast mounted with a slight angle to the other, in a transversely symmetrical manner, so that the blades intermesh without colliding.
