Idle-Up-
A switch on the controller actuates a special function, known as “idle-up.” Idle-up
offers an alternate throttle and pitch curve, different from the curves used for hovering.
Idle-up is usually used for aerobatics, when the pilot wants engine power added when
pitch is subtracted. For example, inverted hovering requires positive throttle and
negative pitch. As such, pulling the collective stick back provides positive throttle
AND increased pitch simultaneously.
Throttle Hold-
Another special function is known as the “throttle hold”. When activated, this switch
sets your throttle to idle but allows the collective to function normally. This allows you
to practice autorotations without shutting the engine off.
Gyro-
Any sudden change to the torque of the main rotor, such as a quick change in RPM or
a wind gust, can cause the helicopter to turn unintentionally to an unwanted direction.
An electronic device known as a gyroscope (gyro) is used to “monitor” and correct for
this by giving commands to the rudder control to help stabilize the machine.
Gyros come in a variety of types, each with different features. A normal gyro will not
return the helicopter to its former heading; it will simply dampen the unwanted sudden
movement. We recommend you start by using the heading hold gyro instead; it will
maintain course and keep the nose of the helicopter pointed in the desired direction
regardless of outside forces.
