21 RC Programming
Programming 120° CCPM Programming 120° CCPM
As the programming procedure varies with different types of R/C systems, it is necessary for you to
refer to the instruction manual of your R/C system. Here are only a few general guidelines which apply
to most systems.
Servo Centering with Sub-Trim Function
As indicated in the above sections on mounting the servos, it is important that the servo arms are
exactly centered. You should use the servo sub-trim function of your R/C system for this purpose.
Activating 120° CCPM
Likely, the 120° CCPM function is initially disabled in your R/C transmitter software and needs to be
separately activated. Please refer to your R/C system manual, where you will also find information on
which channels should be used for the elevator servo and the two roll servos. It is important that you
stick with the requirements stated in the manual. Otherwise the 120° CCPM will not function properly.
Your R/C may support various different CCPM mixings. For Logo 20 choose the 120° mixing with two
roll servos in the front and one elevator servo in the back.
Use the relevant menus for setting the mixing proportions for roll, elevator and pitch functions. Begin
by setting the mix values to 50% each. Higher mix values give higher servo travel for that function
This can have the unwanted result that the swashplate reaches its limits and causes damage to the
servos or rods or to the swash-plate itself.
If necessary, you may use the CCPM menu to reverse the direction of the function. This is necessary,
for example, if the swash-plate tilts to the wrong side or the pitch function is inverted. The menu for
reversing servo functions can be used for reversing the movements of individual servo arms, but not
for reversing the entire control function and of all the involved servos.
Aileron and Elevator Travel
The travel range of the aileron and elevator servos are limited by the swashplate’s mechanical limits.
Please take care that the swashplate does not hit the maximum of its travel. This can have the unwanted
result that the swashplte reachies its mechanical limits and causes damage to the servos or rods or to
the swashplate itself. e Gestänge und die Taumelscheibe.
If you desire more agility for your helicopter, use lighter flybar paddles.
