▋ Throttle hold【THRO HOLD】
▋ Function Explanation
This function is used for autorotation landings ‒it holds the Throttle Servo at a low position,
while the pitch stick continues to work normally. Using a selected switch, the engine can be cut, or fixed at an
optional slow position. Further, there is also a Stick Auto function that allows switching of the servo to the Hold
position when the stick is lowered to a preset position.
▋ Setting Method
This function is inhibited “INH” by default. Set the function to ACT. Then adjust the hold position as required. The
Hold switch is used by default, but this selection can be modified.
By default, the “HOLD SW” is allocated to POS1. It is possible to allocate this switch to any desired switch
location.
Stick Auto Function (STICK AUTO)
When “STICK AUTO” is set, the servo will change to the Hold position when the stick is lowered past a
predetermined position. To deactivate this function simply turn off the allocated switch. Initially this function
is inhibited. To activate this function, move the cursor to “INH”, and press the dial to “ACT”. Move the cursor to
the inversed display next to STICK AUTO, Move the throttle stick to the desired position and press the “STO” key
to set the position (a numerical value between 0-100 will be displayed on the inversed display). To “INH” this
function, press the dial for more than 3 seconds, to CLEAR.
Hold delay function (DELAY)
It is possible to set a “DELAY“ to prevent a sudden increase in engine rotations when the Hold switch is set to
OFF. The duration of the delay can be set between 0.1 to 2.0 seconds.
By setting throttle hold active, this function acts like an additional flight mode. It is possible to set dedicated Dual
rates, Pitch Curve, etc to this function.
▋ Caution Note
Operate the servos and carefully confirm the control surfaces move as expected before flying.
