Servo movements: If one or more of these parameters is checked, the recorder will log the positions of the
corresponding servos, assuming you have the optional ‘Y’ cables installed. Choose these options if you want to see
controller movements during your flight, etc. .

Servo Glitches (requires Y cable installation): If this option is selected, the recorder detects and logs three different
types of servo glitches: short servo pulses (less than 740uSec), long servo pulses (greater than 2.25 mSec) and missing
servo pulses (no pulse for 100mSec). The most common causes of glitches are low receiver or transmitter battery,
driving out of range of your transmitter, or defective receiver. Note that it is normal to see a series of glitch notifications
right after the recorder or the transmitter is powered up.

Receiver Battery Voltage: Selecting this parameter causes the recorder to log your receiver’s battery voltage (or
whatever battery is being used to power the recorder). Note that it is normal to see rapid spikes in the receiver battery
voltage on playback, but if you are seeing voltage drops below 4.5 volts on a regular basis, you should test your battery.
The Recorder constantly monitors battery voltage even if this option is not checked, and will shut itself down if the battery
voltage consistently is below around 4.5 volts to save power for the receiver. The recorder will log an error in this case.
The recorder will “reboot” if the voltage falls below 4.35 volts even for a short period, and logs an error in this case also.
Error logs are displayed in the “Notification Area” of the application during playback.

Speed: If this option is selected, the recorder logs the speed of your model via the air pitot tube.
