The throttle hold function enables the throttle servo

to be held in a specific location, while allowing the

collective pitch servo to move independently with

the throttle stick. The purpose of this function is for

practicing autorotation landings with the helicopter’s

engine at idle. When the throttle hold switch is

changed from off to activated, there will be a third

adjustable pitch curve added to the pitch curve

function. The throttle hold switch is located on the

top right rear corner of the transmitter. The throttle

hold is on in the forward position. In the back

position, the throttle hold function is off.

1. Turn on the transmitter.

2. Press the SCROLL and INSREASE buttons

simultaneously to enter the Function mode.

3. Press the SCROLL button until “HLD” appears on

the screen.

4. The factory setting for the Throttle Hold function is off.

Note: When the Throttle Hold function is off, the

throttle hold pitch curve will not appear in the

pitch curve function.

Press the INCREASE or DECREASE button to

activate the Throttle Hold function. The throttle

hold pitch curve will now appear in the pitch

curve function. To inhibit the Throttle Hold

function, press the CHANNEL and INCREASE

buttons simultaneously.

5. Using the INCREASE or DECREASE button,

adjust the throttle hold value to deliver a reliable

engine idle speed. To do this, set the throttle

trim to your normal starting idle setting (1/2, 3/4,

etc.). Next, with the engine off, adjust your

throttle hold value so that, when you change the

throttle hold from on to off, there is no movement

of the servo arm. The normal range of throttle

hold is from -2 (1/2 trim)

to +15 (full high

trim).

6. Press the SCROLL button to access the pitch

curve function.

7. To exit, press the SCROLL and INCREASE

buttons simultaneously.
