By controller: holding the throttle down, and rudder right for 5 seconds. Do not hold the rudder
right for too long (>15 seconds) or you will begin the AutoTrim feature
By GCS: Connect the flight controller to GCS. There should be a "Action" tab under the HUD. Click
the button Arm / Disarm to arm the vehicle.
Tips For New Pilots
Note: UAV is not a toy and it may cause injuries. Make sure there is no people or obstacles 50m
around.
It is recommended to use Stabilize mode in your first flight. The throttle in Stabilize mode is linear so that
the sensitivity is relatively low.
After flying in Stabilize mode for a while, keep altitude above 1m. Assuming that all is fine so far, you’re
ready for more advanced modes. Switch to AltHold, Loiter, and other modes to practise them. The control
logic of AltHold, Loiter are different from Stabilize. Releasing the throttle stick will keep the vehicle at the
current altitude. Climb when pushing up and descend when pushing down.
Note: Please read and understand the characteristic of flight modes before actually using it.
Optional Hardware
IMU Temperature Control
IMUs in The Cube are temperature-controlled by onboard heating resistors. Target temperature can be set
by changing BRD_IMU_TARGTEMP in Full Parameter List. Optimal temperature of IMU is 60 degrees Celsius but
it may takes a while (around 10 minutes, variate to actual environment) to reach target temperature.
Therefore default temperature in ArduPilot is set as 60 degrees Celsius to shorten the heating time.
It is recommended to set BRD_IMU_TARGTEMP to 60 and wait for a while for pre-heating, if you need to
maximize the accuracy. After pre-heating, reboot The Cube. Flight controller will re-log the IMU data and the
IMU measurement will be at best performance.
GPS Blending (aka Dual GPS)
Only GPSs that report position and speed accuracy can be used for blending. All UBlox GPSs provide this
extra information while GPSs using the NMEA protocol generally do not.
Normally blending should be done with two GPSs from the same manufacturer because the scaling of the
accuracy numbers varies and will lead to favouring one GPS over the other.
Note: Two GPSs should not be used on Copter-3.4.5 (and older) firmwares because of the risk of
sudden vehicle movements when the primary GPS changes. Copter 3.5 (and higher), Plane 3.8.0 (and
higher) and recent versions of Rover all support GPS Blending.
