During Takeoff

The following should be monitored directly after takeoff while the vehicle is ascending vertically to its transition altitude.

Landing Gear Not Retracting

Operator Action: LAND

During takeoff, the landing gear should retract at approximately 3 meters above the ground. If the landing gear fails to retract—either partially or fully—the operator must immediately initiate the LAND command. This will deploy the retracted landing gear, and the vehicle will autonomously land at the takeoff location.

If necessary, the operator can use the nudging function to reposition the vehicle. Use nudging with caution when the vehicle is close to the ground.

After landing, contact [email protected] for further assistance.

Toilet Bowling

Operator Action: LAND or ALTITUDE

The vehicle should take off in a straight line after the first few meters. If the vehicle starts "toilet bowling" (circling up), the mission should be aborted and a sensor calibration must be performed. If an autonomous landing does not stop the toilet bowling behavior, ALTITUDE mode should be engaged for a manual landing.

Not Holding Position

Operator Action: LAND or ALTITUDE

The vehicle should take off in a straight line. If the vehicle starts drifting from its position by more than a few meters, it should be commanded to LAND. Contact support to have your log files analyzed. If an autonomous landing cannot safely be performed, ALTITUDE mode should be engaged for a manual landing.

Takeoff Failure

Operator Action: DISARM (Emergency Action -> SHUTDOWN)

If the vehicle fails to take off or only one-half of the vehicle rises, the VTOL propellers are likely damaged, mounted incorrectly, or upside down. The operator should disarm the vehicle and review the propeller configuration as described in the manual.
