Normal Mode and Idle Up Mode are the two flight modes most frequently used by collective pitch helicopter pilots. Idle Up mode is what most RC helicopter collective pitch pilots fly. In Idle Up mode, the rotor spins at a high … Continue reading
Heli Setup
Lateral cyclic direction. Specifies the direction, Normal (—) or Inverse (INV).
Longitudinal Cyclic Direction. specifies the direction, Normal (—) or Inverse (INV)
Normal mode and Idle Up mode are the two flight modes generally used by Heli pilots. Most experienced RC helicopter pilots fly almost exclusively in Idle Up mode. Normal mode means low throttle stick with engine at idle or off.
Allows an RC helicopter’s main rotor to rotate even when the motor is stopped. Very much like a bicycle gear for a rear wheel. Allows a helicopter to autorotate (land without power).
Abbreviation for One Way Bearing
Difference in direction of tilt of the swash plate versus the direction of tilt that a helicopter will take when flying.
An RC helicopter move where collective is rapidly changed between full positive and full negative. Used to test the reaction of the tail and the drive system when the helicopter is under load.
An older style of gyroscope that limits the rate of change in direction. Opposes sudden shifts in direction but allows slower changes such as “weather vanning” , or pointing the helicopter into the wind. Momentary use of rate mode can realign a helicopter with … Continue reading
A circular plate that adjusts the pitch of helicopter blades on each rotation.
Specifies limits to swash ring travel.
A switch set up on a RC model Tx used to stop an internal combustion motor or an electric motor.
A switch in a RC helicopter Tx set up that sets a heli throttle to low value regardless of any other input. Often seen as another flight mode employing a separate pitch curve.
A type of RC helicopter having a tail rotor that is turned by the main drive gear using a rod that rotates inside the boom.
Abbreviation for Torque Tube
Tendency of a model to point into the wind due to unbalanced side forces on the front and rear of the craft by the wind. Occurs in both fixed wing and rotary wing aircraft.
