5.3.4 THROTTLE HOLD

This function holds the engine in the idling position and disengages it from the THROTTLE STICK when
SWITCH AT9 is moved. It is commonly used to practice auto-rotation. Prior to setting up THR-HOLD, hook up
the throttle linkage so that the carburetor is opened fully at high throttle, then use the digital trim to adjust the
engine idle position. To have THR- HOLD maintain idle, move the THROTTLE STICK to the idle position,
then move the hold SWITCH on and off and keep changing the offset value until the servo does not move. To
lower the engine idle speed, or if you want to shut off, input a more negative number.
Adjustability:
• Idling position: Range of -50% to +50% centered about the throttle idle position to get the desired engine
RPM.
• Switch assignment: Assigned to SWITCH E(AT10) or G (AT10) down. Adjustable in the CONDITION
(THR-HOLD item), (2-position type switch only)
• Throttle curve: Since the throttle is moved to a single preset position, no curve is available for THR-HOLD.
