USER GUIDE

The propellers will spin when the multirotor is armed. Do not arm your multirotor with propellers

attached until you’ve verified that motor direction, propeller direction, motor order, idle throttle and

other settings are correct! Make sure you don’t inadvertently move the stick(s) to the arm corner!

The multirotor is disarmed by moving the throttle stick to the off position, and holding the rudder stick in the

leftmost position for 1 second. For Mode 2 radios, this is done by holding the left stick in the lower left-hand

corner (the DISARM corner) for approximately 1 second.

The figure below refers to the left stick of Mode 2 radios:

Don’t disarm your multirotor while flying unless there’s an emergency! If you do, the propellers will not

spin until you rearm it as described above.

5.11.4.2 Issues that will prevent arming

Here are some conditions that will prevent the multirotor from arming, for safety reasons. An error

message will appear in the OSD notification area if these conditions are detected (see section 7 on

notification messages).

 Arming in a GPS mode (including RTH Test mode), unless you have selected that option in the

Advanced Multirotor menu. See the table in 6.8.3 if you are uncertain about which modes require a

GPS.

 Arming in a leveling mode (2D, 2D with Hold, Cartesian, etc.) if the multirotor is not level. Note that the

multirotor can be armed in 3D mode if it is not level!

 Arming if the multirotor is not completely still.

 Throttling up if the low battery auto-land feature has been triggered (the multirotor will arm in this

condition).

 Arming if a controller error was detected during Vector boot-up.

 Arming if the Vector has not been fully configured.

 Arming if USB is connected.

5.11.5 Setting Idle Throttle (Multirotor only)

When the multirotor is armed and the multirotor is level, the motors are commanded to spin at the idle

throttle setting. You can change this setting by invoking menu mode, navigating to the “New Airframe

Checklist” menu, and changing the “Idle Throttle (microseconds)” menu item.

The idle throttle should be adjusted so that the motors spin when armed, but not fast enough to lift the

multirotor. In addition, the idle throttle should be set high enough so that the propellers will not stall in flight.

If the idle throttle is set too low, the motors won’t spin when armed, and the multirotor could stall during
