16.4 PPM Mode
16.4.1 Introduction
The »Xtreme provides the option to allow users to install a PPM RECEIVER in order to
control the »Xtreme with a standard RC transmitter instead of the default stock transmitter.
Do not confuse PPM (Pulse-position modulation) and PWM
(Pulse-width modulation).
The PPM receiver uses PPM technology. However, you may
operate the »Xtreme via an RC transmitter using PWM
technology.
The»XtremedetectstheinstalledPPMreceiverautomatically.Auto-detectionrequiresthat
thePPMreceiverhas been successfullypaired(binding)withthe respective, matching
standard RC transmitter.
If a PPM receiver is detected, inputs given from the default
stock transmitter are ignored.

16.4.2.1 Removing
Carefullypullthecanopy(3) off the »Xtreme with one hand. All four sides have to detach
simultaneouslytoavoiddamagingthecanopy.
After removing the canopy, the flight controller (main
board) is exposed. Do not touch any electronic components.
Electrostatic discharge causes damage.
16.4.2.2 Mounting
> The canopy must only be mounted in one direction. The reason for it is the
ATMOSPHERIC PRESSURE METER, which has to be covered by the FOAM
CUSHION situated inside the canopy. The foam cushion minimizes interferences
causedbyairow.
