Changing the Throttle Hold Percentage Value - Throttle Hold Function Active
WARNING Keep in mind that it's possible to set the Throttle Hold lower than the throttle End Point Adjustment. For example,
with the throttle End Point Adjustment set to -100% and the Throttle Hold set to -150% the servo will move -150% when the
Throttle Hold is Activated. We strongly recommend that you set your Throttle Hold no lower than your throttle End Point Adjustment
unless specifically necessary for your particular setup. This will prevent any chance of overdriving your control linkage.
1) Press the Navigation Pad 6 to highlight >-100%.
2) Press the YES/+ or NO/- keys to set the position you would like the
throttle servo to Hold at.
TH-HOLD setting range is -150% to 0%. The default setting is -100%.
Increasing the TH-HOLD percentage value will increase the position at
which the throttle servo will Hold at and decreasing the TH-HOLD percentage
value will decrease the position at which the throttle servo will Hold at.
When the Throttle Hold function is Activated, the Throttle Hover trim switch will be disabled and you will not be able to
control the Hovering Throttle function. This is normal.
Turning ON the Throttle Trim Function - Throttle Hold Function Active
The Throttle Trim function allows you to have throttle trim control even with the Throttle Hold function Active. This allows you
make minor adjustments to your throttle speed as required.
1) Press the Navigation Pad 6 to highlight TH-TRIM>OFF.
2) Press the YES/+ or NO/- keys to change the OFF/ON setting.
TH-TRIM setting range is OFF/ON. The default setting is OFF. When set
to ON, you will control of the full range of throttle trim from the position
that the Throttle Hold percentage value is set at. When the Throttle Trim
function is set to OFF, the Throttle trim switch will be disabled.

The Pitch Curve function allows you to vary the amount of pitch travel in relation to the movement of the throttle control stick at
different points throughout the entire range of deflection. Nine custom-programmable Points ensure an extremely precise Pitch
Curve to suit any type of situation. For example, if you are doing 3D flying, you may want a Linear Pitch Curve with maximum
negative pitch when the throttle control stick is at low, maximum positive pitch when the throttle control stick is at high, and
0 degrees of pitch when the throttle control stick is centered. Alternatively, for a more docile flying helicopter, you may want
minimum negative pitch when the throttle control stick is all the way back and gradually increase pitch in small increments as
the throttle control stick moves from low to high, to produce a smooth transition from low to high throttle.
The Pitch Curve function can be programmed separately for each of the five Flight Modes. An Input and Output display, along
with a graph, help with programming visualization.
