Not fixed

A propeller is said to have a fixed pitch when its blades are fixed (this is the most common case); in other words, they can not change inclination.


To raise or lower a helicopter whose rotor is fixed pitch, it is necessary to slow down or accelerate the motor that drives the rotor. This is often the case for the simplest radio-controlled helicopters.
