The Throttle Hold function holds 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 activates (ACT) or inhibits
(INH) the Throttle Hold function.
4. Once the Throttle Hold function is activated, the screen
displays the current Throttle Hold value.
5. Move the Selector to highlight HOLD Pos, then
press. Roll the Selector to increase or decrease the
Throttle Hold value.
6. To exit the Throttle Hold function, move the Selector
to highlight LIST, then press.
Note: When the Throttle Hold is activated and
the switch is on, the ‘’HLD“ indication on the LCD
displays just under the battery voltage bar.
The Stick Auto Setting acts as an automatic Throttle cutoff
point.
This feature allows you to select the throttle stick position
in which the throttle hold function can be activated in the
Throttle Hold mode. Although the throttle hold switch is
active, when using this feature the throttle continues to
function until the throttle stick is moved below the cutoff
position you select.
To activate the Stick Auto function, highlight the Stick
Auto function with the selector, and press to access. Next,
roll the selector to increase/decrease the position of the
cutoff point.
The Hold Delay function allows the throttle servos’
movement to be slowed when switching from Throttle
Hold back to a previous Flight Mode. This feature is
helpful when practicing Autos. If the autorotation attempt
is not going well, when the Throttle hold switch is
released, the throttle increases more slowly, eliminating
any sudden bursts of throttle which could damage the
mechanics of the model.
The adjustable range is from 1/10 of a second, up to a full
2 seconds of delay.
To activate the Hold Delay, highlight the Hold Delay
function with the selector, and press to access.
Next, roll the selector to the desired delay position, and
press the selector to store. A good starting value is
.75 (3/4) of a second.
