9 CHANNEL 2.4GHz AIRCRAFT COMPUTER RADIO SYSTEM
9 CHANNEL 2.4GHz AIRCRAFT COMPUTER RADIO SYSTEM
When flying very fast, small tiny movements of the control surface are required. We will call the small movements “low rates”.
Since we already have our high rates set-up, let’s set another rate, or servo arm travel distance that is smaller and will give us small
control surface movement. This “low rate” can be activated by selecting a switch when you are flying.
Here is how to set up your aileron and elevator travel using the dual rate functions.
a. The first control surface to change is the aileron;
AILE pops up as the active function when entering this screen.
b. Select “Rate” to highlight both R&L. This allows you to change both sides of the
servos travel rate at the same time.
c. Move the aileron stick to the left, hold it there and press the
–
icon until
you reach 75%.
d. Now select a switch that we can throw while flying that will cut the aileron
travel down to our 75% setting.
e. Press the
NULL
icon to select the switch for our dual rate function.
This screen holds two valuable functions, dual rates and exponetial rates. Both functions are controlled at this screen.
Using the dual rate function allows you to select a switch that can change the travel rates or distance the servo arm moves a control surface.
We will first demonstrate dual rates, then show you how to program exponential rates.
A good example is that; even a very fast plane must take off and land at a relatively slow speed compared to how fast it may fly at full
throttle. What is needed are two servo arm travel rates, dual rates, that we can program and then use a switch to select between these
rates. When flying slow, full control movement is necessary, we will call this “high rates”, and it is what you currently have set-up based
on the EPA values.
29. Select
D/R&EXP
from the model menu
a. Let’s select switch “
A
”.
b. Select the
Exit door
icon twice to back out.
31. This is a map of the Aurora switch layout.
You can put the aileron dual rate function
on any of the switches shown.
30. At the intermediary switch screen
press the
SEL
icon.
Now we can apply exponential rates to the aileron and elevator controls.
Using exponential rates allows you to shape the normally linier movement of a control surface. Our goal is to soften the middle of the
stick around the center point for the "high rates". You will see this curve shaped on the graph displayed on the screen. Using negative
expo values will help any pilot fly smoother on high rates, with greater control over their aircraft.
We will apply a -40% value to the expo setting for both the aileron and elevator high rates.
a. Apply expo to your aileron control by selecting the AILE controls using the control
select
arrow
.
b. With the switch “A” in the position that gives us our high rate setting of 100% travel
in dual rates, touch the
EXP 0%
icon to activate it.
c. Now press
–
to apply a -40% value. See how the curve of the aileron servos
movement changes to “soften” the center of the aileron control sticks travel.
d. Change to the elevator again by pressing the
arrow
to the right of the AILE.
e. Repeat steps to program our -40% EXPO value for the elevator high rates.
Your plane should now be ready to fly. Do a range check and pre-flight, then go have fun!
Now by throwing one switch, you can select to use dual rates and have expo on your elevator and ailerons.
34. Using Exponential Rates
For more advanced users, different expo and D/R values can be applied with individual switches and/or
under multiple flight conditions.
33. Follow steps 29 -31 to program a 75%
value for the elevator dual rate. Select the
elevator dual rate to be active by assigning
it on the same switch, “A” for the purpose
of our demonstration. Be sure to put the
75% elevator value on the same switch
“position” as our 75% aileron value.
8
a. Run through the same steps to select a dual rate for your elevator.
We change to the elevator function by pressing the
arrow
icon to the right of AILE.
Now it should read ELEV.
32. Now we are back to the D/R&EXP screen.
