CURRENT and CONSUMED values will also help determine this. The DeltaQuad should draw between 9
and 15 Amperes of current on average during cruise flight. This value increases;
The vehicle is flying significantly above sea level
If the vehicle is flying with maximum payload.
As the battery percentage drops.
When the vehicle is climbing or banking.
When the cruise throttle is set higher.
When the LiPo gets older.
When a power consuming payload is active.
Ground speed
Operator action: Increase cruise throttle
The DeltaQuad will generally maintain a constant speed through air, but wind conditions will impact the
effective ground speed. If the ground speed drops below 6 m/s the cruise throttle should be increased.
Increasing the cruise throttle can be done by changing the parameter as described in the
. This parameter can be changed during flight.
Note: When changing the cruise throttle during flight special care must be taken to monitor the battery level.
Key parameters
section
When this happens the vehicle is likely flying in wind conditions that exceed the .specified tolerance
When the DeltaQuad is flying towards its last waypoint (the VTOL_LAND waypoint) it will determine the
appropriate distance from the waypoint to initiate its back transition. The distance depends on the current
ground speed and can vary between 5 and 100 meters from the land position. During the back transition the
DeltaQuad will activate its pusher motor in reverse direction to slow down.
Excessive overshoot
Operator action: None
If the vehicle overshoots its landing waypoint significantly and does not seem to slow down during back
transition, there could be a problem with the pusher reverse system. The vehicle should be thoroughly
inspected for loose connectors on the flight controller (specifically connectors 7 and 8 as indicated on the
). If no problem was found with the connectors the vehicle should be grounded and undergo
extended maintenance.

Unstable descent
Operator action: None
If the vehicle becomes unstable during landing the land speed as indicated in the is likely set
too high.
safety features
No auto disarm after touch down
Operator action: Disarm
The DeltaQuad should disarm automatically 5 to 10 seconds after touch down. If the vehicle does not disarm
automatically the disarm command (emergency stop) should be sent. This command can be sent by
pressing the "Armed" label.
The reason for this could be related to landing on a significantly uneven or surface or slope. It can also
