WebbBy changing the angle of blade pitch (angle of attack) of each rotor blade as it makes one revolution or cycle, we can vary the amount of lift (or thrust if you prefer to think of it that way), anywhere withing the rotor disc and thereby move the helicopter in any direction. WebbMicro RC Helicopters have a main rotor diameter of under about 15" (but probably over 7"). Collective pitch micro helis are typically flybarless to save on weight. Most FP and coaxial helis are categorized in this micro section, but a few make it into small.

WebbA helicopter has three types of pitch control: collective pitch, cyclic pitch, and differential pitch control. Blades on a helicopter are pitched, or angled, in different ways to control … WebbThe manufacturer specifies a minimum and maximum RRPM for each helicopter type. The normal RRPM range is marked on the RPM gauge as a green arc, with permitted cautionary ranges marked in yellow or amber and enclosed by a red mark indicating the minimum and maximum permitted.

WebbThis is greatly dependent on the imbalance of the helicopter tail rotor which is predominantly caused by the uneven distribution of weight of the blades. Generally, imbalance is adjusted by weight, pitch control rod and trim tab. Furthermore, the rotor blade defects can also cause the rotor to go out of track.
