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.
