Function Details :
This function is used to maintain the
throttle channel
position as preset position. The default rate
is 10.0%. Throttle will be in preset position after this function is applied. It is commonly used to practice
auto-rotation landing.
Touch the
throttle hold
and move the wheel to modify the corresponding value. This function
can be assigned to a
switch
(from SwA to SwH, LSw).
For this example:
Throttle hold
value is set to 30% and push the SwA
upward
to enable this
function. The channel position is displayed at 30 in real time. Throttle value will not be changed while
moving the
throttle stick
.
Function Details :
This function is the pre-programmed mix for some special functions and it can mix
aileron
channel,
elevator
channel and
rudder
channel. The default is as shown in picture 23.2. This function can be set
up in 5
conditions
. For example, in order to not reduce the height and maintain speed, control the
elevator
and increase the throttle output automatically.
Select the desired
Down
or
Up
and move the wheel to modify the corresponding value.
As shown in the picture23.2: The value of the
aileron downside
is set as -15% and the value
of the
upside
is 15%.
Function Details :
This function
is used to adjust the pitch of the helicopter with the variable pitch to achieve the best flight effect.
It will be presented with curve distribution. This function can be set up in 5
conditions
respectively, and the 11
points (L, 2~10, H) of
throttle curve
can be adjusted from 0% to 100%. The horizontal dotted line displays in real
time the
throttle stick
position and the vertical dotted line displays in real time the position of
pitch curve
output
after this function. This function icon will not be shown if the structure is fix pitch.
Select the desired point and move the wheel to modify the corresponding value.
For this example: The
pitch curve
function is activated. Point 2 is set to -72%, point 3 to -43%,point
4 to -15%
and point 5 to 10%,point 6 to 38%,point 7 to 63%,point 8 to 85%,and point 9 to 97%. Other points are not adjusted.
In this situation, when the position of the
throttle
is below the neutral, that is (L, 2~5), the acceleration of the
pitch
curve
output is faster than its position above the neutral ( that is 6-10, H point).
