THRO HOLD- THROTTLE HOLD
H-20
The Throttle Hold function is designed to hold the
throttle servo in a specific position during an autorotation.
This is very useful for practicing autorotation landings.
The Throttle Hold switch is located on the top right-rear
corner of the transmitter (unless a different switch has
been selected in the Device Sel section in the System
Mode. In the forward position, Throttle Hold is on; in the
rear position Throttle Hold is off.
The proper Throttle Hold value should deliver the proper
engine idle rpm for your helicopter. The adjustable
range is (-20% – +50%). Once you establish the proper
idle trim value for your engine, you can use this value
for Throttle Hold as well. To shut the engine off for
autorotation, a negative or zero value should be input.
Accessing the Throttle Hold Function
1. Place the transmitter switch in the ON position.
2. Press the List key, then move the Selector until THRO
HOLD is displayed. Press the Selector to access.
3. Pressing the Selector will activate (ACT) or inhibit
(INH) the Throttle Hold function.

Throttle Hold value to the desired position.
