Operator action: LAND
The vehicle should takeoff in a straight line. If the vehicle starts drifting from its position more than a few
meters it should be commanded to LAND. Contact Vertical Technologies support to have your log files
analyzed.
Takeoff failure
Operator action: DISARM
If the vehicle fails to takeoff or only one half of the vehicle rises it is likely that the quadcopter propellers are
damaged, mounted incorrectly or upside down. The operator should disarm the vehicle and review the
propellers configuration as described in the .assembly section
Excessive current draw
Operator action: LAND
If the current draw indicated by CURRENT from the telemetry display exceeds 180 Amperes the flight
should be aborted. The vehicle could be over weight, flying outside of or has a
malfunction. In the case of a malfunction inspect the vehicle for visible damage to the propellers or a higher
resistance in any of the motors. If there was no evident damage then contact Vertical Technologies support
for analysis.
tolerable wind conditions
After reaching transition altitude the vehicle will commence the transition to fixed-wing flight. (switching from
quadcopter to fixed wing). It will transition into the direction that the vehicle was placed in, but wind can have
an effect on the direction, especially if the vehicle was not positioned with its nose directly into the wind. The
vehicle will engage full thrust for 15 seconds using its pusher motor. After this period it should navigate
towards the takeoff location or the first waypoint.
No forward motion
Operator action: LAND
If the vehicle is not moving forward or is drifting with the wind and does not seem to transition towards fixed
wing there is likely a problem with the pusher motor or propeller.
Flying backwards
Operator action: LAND
If the vehicle starts flying backwards with increasing speed it is likely to have the pusher propeller mounted
in the wrong direction. The transition should be aborted and the pusher motor should be inspected.
High current slow forward flight
Operator action: RTL
If the vehicle is moving horizontally in the direction of the first waypoint at low speed, with the quadcopter
motors still engaged after 15 seconds, and the current draw remains above 30 Amperes, it is likely that the
mission did not issue a VTOL TAKEOFF command but a TAKEOFF command. The vehicle will attempt to
complete the mission in quadcopter mode. If this was not intended, RTL should be initiated by the operator.
Note: The DeltaQuad can activate its pusher motor in quadcopter mode too. The spinning of the pusher
motor is no indication that the vehicle is attempting fixed wing flight.
