RC Helicopter Glossary

3D (flying)

This is  high performance flying combining varying maneuvers at the same time. If you need to understand 3D Flying simply go to YouTube and search "Helicopter 3D Flying".


The Ailerons are what tilts the helicopter left or right. This term is more aimed at planes than helicopter and is called a cyclic roll.


This is the shape of the blade which is what creates the aerodynamic forces necessary to keep the helicopter in the air as air passes the rotor blades. This is the main component that creates the helicopter flight ability.


 This is a term used in the radio controlled shop trade which stands for Almost Ready to Fly.


This is the name given to a maneuver where you can land a helicopter with no engine / motor when failure occurs. The momentum of the rotor blades spinning as the helicopter is dropping out of the sky is enough to slow the heli down just before landing and prevent damage. This is something that only advanced fliers will be able to do.

Ball Linkage

The connections that link the control mechanics such as the servers to swash plate. This allow adjustment using the threaded bar and ball setup. The one end link will snaps onto the ball securing the mechanics of the link.


When two gears come in contact and mesh the distance between the teeth is important as if there is too much of a gap between the teeth (too little backlash) then the teeth on the gears will break. If the gap between the teeth is not enough then excessive wear will take place. You can use sheets of paper to measure and set the amount of backlash.


This is shorten from Cyclic-Collective-Pitch-Mixing, CCPM mounts the swash plate at 120 degree increments like an equilateral triangle. Using three servo's the swash plate has the ability to move in any direction.

Collective Pitch

This describes the control movement that adjusts the pitch of the rotor blades. Adjusting the pitch of the blades causes the helicopter to ascend or descend without the changing the rotor speed.


This describes the controls which make the adjustment to the horizontal attitude of the helicopter.

Dual Rates

This is a feature of some Transmitters models where the ability to flip a switch and make the controls more or less sensitive.


This term is shortened from Electronic Speed Controller. The ESC is the device that takes the controls the battery power to the motor providing a certain amount of power to the motor depending on the transmitter movement.

Servo Binding

This is the condition where the control ajustments do not match the maximum servo travel and when the servo is at its maximum movement themovement is restricted and this puts torque on the servo constantly and will reduce the life of the servo.
