ADJUSTMENTS AND FLIGHT TECHNIQUES
IDLE UP 1.2
Idle-up 1 and 2
• Idle-Up or "High Idle" functions allow the collective pitch to be reduced while engine
speed is reduced to a lesser extent. This allows a more constant engine and main rotor
speed during hovering and certain aerobatics. Collective pitch response is improved.
• Two separate Idle-Up circuits are provided. Idle-Up 1 is usually used for normal hovering
and forward flight, while Idle-Up 2 is usually reserved for aerobatics where a high rotor
speed is needed at low (negative) pitch settings (while inverted during rolls, etc.).
• Each Idle-Up circuit has a "Point" and "Rate" adjustment. The "Point" is the T/C stick
position above which the Idle-Up has no effect. The "Rate" adjustment sets the throttle
servo response curve as the stick is moved below the Idle-Up "Point".
• The CURVE adjustment on the IDLE-UP screens can be used to refine the shape of the
response curve below the idle-Up "Point".
• The DELAY function slows the servo movement from the normal to idle-Up position
when the idle-Up Switch is turned ON. This makes the transition in engine speed less
abrupt.
Setting Method

ed above the Idle-Up Point, "OFF" is dis-
played in ( ). As the stick is moved below
the point, "ON" appears in ( ) to indicate
that the Idle-Up function is operating (if the
appropriate Idle-Up switch is ON). The Point
cannot be set above the 75% position or
below the 25% position.
