Landing Gear
The Dragon X750 is equipped with retractable landing gear, controllable
from the Walkera DEVO F12E Controller. Switch 3 is used to retract and
extend the landing gear as shown in figure 7. When using Return to Land
Mode the landing gear will automatically deploy, however, when landing
manually the landing gear needs to be deployed manually.
CAUTION
: Never attempt to land the Dragon X750 with the landing gear
retracted. Always deploy the landing gear before landing.
Calibration
It is a good idea to calibrate the compass and accelerometer whenever
flying the Dragon X750 in a new location or after having maintenance
done on the aircraft.
Compass Calibration
CAUTION: Do not calibrate the compass in parking garages, close to
buildings or near roads with a metal core. For optimum performance only
calibrate the Dragon X750 in open spaces far away from power lines and
other metal structures or concrete buildings.
