Notes:
If the ailerons deflect in the wrong direction after you have selected spoilerons,
swap over servos 1 and 5 at the receiver.
!!
The spoiler signal is still present at channel 6.
Deploying the spoilerons may produce a change in pitch trim. You can correct this
automatically with the SPL-CO mixer (see 8.5.7. Elevator compensation).
8.5.7. Elevator compensation for throttle, flaps and spoilers
The COCKPIT
MM
offers three automatic elevator correction mixers which automatically
compensate for pitch trim changes caused by power systems, landing aids etc.
These mixers make it much easier to control the model, as you no longer need to
use the elevator stick to correct the pitch trim changes when they occur.
Elevator compensation Input signal Signal source
Power compensation PWR-CO Throttle control
in mode 1 - 4: stick B or D
in mode 5 - 8: control F
Flap compensation FLP-CO Flap control always control E
Spoiler compensation SPL-CO Spoiler control
in mode 1 - 4: control F
in mode 5 - 8: stick B or D
This is how you activate the elevator compensation mixers (Example: PWR-CO):
Procedure Display
1.
Select the PWR-CO setting in the MIX menu and
switch to the second line
2.
Set the required elevator compensation, e.g. -10%
3.
Return to the first line
Continue as shown in the flow chart
The FLP-CO and SPL-CO mixers are set up in the same way.
If you set elevator trim compensation and the result is an elevator movement in the
opposite direction to the one you require, set the value to a negative figure (e.g. -
10% produces deflection in unwanted direction > +10% = correct deflection).
Note:
If the operating instructions for your model do not state figures for elevator pitch
trim compensation, we recommend that you ask an experienced pilot to test-fly
your new model. He will be able to tell you the amount and direction of compensa-
tion required.
