PIT CURVE/PIT TRIM
Pitch Curve
This function adjusts the pitch operation curve
for each flight condition to optmize the model's
performance in relationship to the throttle stick
position.
*A simple curve can be created by reducing the number of
input points to two or three, and then entering the specified
value at the corresponding points.
Normal curve adjustment
*For normal curve, create a basic pitch curve centered
about hovering. Use this function together with the THR
Curve (Normal) function and adjust the curve so that up/
down control is best at a constant engine speed.
Idle up curve adjustment
*For the high side pitch curve, set the maximum pitch
so that it does not overload the engine. For the low side
pitch curve, create curves matched to loop, roll, 3D, and
other purposes and use the idle up curves according to the
performance.
Throttle hold curve adjustment
*The throttle hold curve is used when executing auto
rotations.
Operation precautions
Warning
When actually starting the engine and flying,
always set the idle up condition switch to OFF
and start the engine at idle.
