Once you’ve setup the SYSTEM settings, use the
FUNCTION LIST to complete your set up and adjust
how the helicopter flies and is controlled. The functions
are presented below in the order that they appear in the
Function List .
The descriptions are general in nature and are intended to
provide enough information to decide whether or not to
use a function, and what types of selections and settings
to make.
Press the LIST button after the transmitter is powered up
to obtain the FUNCTION LIST.
Dual Rates and Exponential curves allow you to set up
your helicopter with a particular “feel” in maneuvers.
Just changing D/R and EXPO values can change the
helicopter’s personality, causing it to take on traits that
make certain maneuvers easier for you. At times you
might want the helicopter to feel very crisp, such as
when performing aerobatics, and then feel softer for other
maneuvers such as Hovering. And other times you want
the helicopter to be very crisp but without the tendency
to be over-controlled, like in performing 3D maneuvers.
Dual Rates and Exponential curves can be combined to
produce these traits. When programming a Dual Rate and
Exponential curve, think about what kind of response is
desired from the helicopter.
1. Highlight and select D/R & EXP in the FUNC.LIST
to obtain the D/R & EXP display. There will be 3 sets of
values displayed for each channel – Aileron, Elevator
and Rudder.
2. Use the Selector to change between Aileron,
Elevator and Rudder. Then use it to set dual rate and
exponential values. If you’ve never used exponential
before, try a low positive value like +20. After a while,
increase it gradually until the desired feel is obtained.
Use only positive (+) percentages unless there is a
distinct need to increase control sensitivity.
After plugging all servos into their proper channels
in the receiver, you should first check each servo’s
direction of travel. Move all sticks and switches/levers
while observing each servo to determine if the servos
are moving in the correct directions. Make note of those
servos not traveling in the correct direction and use the
REV.SW function to reverse the direction of travel for
those servos.
1. Highlight and select
REV.SW
in the
FUNC.LIST
to
obtain the servo reversing display.
2. Using the Selector, highlight and select those
channels you need to reverse. Pressing the Selector
toggles the channel between Normal and Reverse.
Note : If any of the versions of CCPM have been
selected, the 3 CCPM channels will be re-named to
CH2, CH3, and CH6, etc. on the display.
The Automatic Dual Rate function allows you to change
the dual rate and expo values of the elevator, aileron, and
rudder by changing the flight mode or throttle hold switch
positions.
This feature simplifies the operation of multiple switches
during flight.
To access the Auto D/R feature, roll the selector to the
right until the D/R Expo graph is replaced by the Auto D/R
Flight Mode list.
Highlight the Flight Mode to be set for Auto D/R, then
press the selector to pick the desired D/R setting for this
flight mode. Repeat as necessary to assign D/R positions
for each flight mode.
