When correctly powered the charger LED Screen will be display
•Insert the Lipo battery balance plug into the Charsoon DC-4S charger
•During charging the Led screen will display total battery voltage and single cell voltage cyclically.
When charging is completed, the total voltage should be 16.8v(±0.1v~0.2v) in the LED Screen.
IMPORTANT ISSUE YOU MUST PAY ATTENTION TO:
•The DC-4S Charger can ONLY used for 2s/3s/4s batteries.
NEVER EVER attempt to charge more than one battery at any time, the charger may get damaged or
catch fire.
•During charging, the DC-4S should be placed in a dry and ventilated place, far away from head sources
and far away from flammable or explosive substances.
•Always remove the battery from the aircraft before charging.
Never charge unsupervised, stay close and keep an eye on the charger for the entire duration of the
process.

Batter y installation
First put the battery anti-slip mat into the bottom carbon board.
Put the battery at the bottom and move it forward-backwards as required for perfect balance and No
interference with other equipment then firmly secure the battery with the velcro strap.
Attention:
(1)Place the aircraft in a wide open space, with the rear facing you.(This position is known as “TAIL IN”)
(2)Put SWB switch to the 2 position (Please set the flight model to stabilize if yours are not RTF Version)
put all trims and dials to the Middle position, move the throttle to the lowest position, then turn on the
Remote Controller.
(3)A video receiving equipment is needed(such as FPV monitor with 5.8G wireless video receiver ,
Goggles glasses ,etc.)to display an image and OSD information.
(4)The V-tail 210 mini-quad have a low-voltage alarm beeper. And the OSD give you a visual reference
for the remaining battery power、fight time, flight height, attitude line, flight speed, Coordinates,
direction. When voltage reach below 14.0 volts and the beeper will sound alarm. The V-tail210
mini-quad is designed for FPV racing there is no “automatic landing mode".

is SWA Switch, and for the ARF Version you need set up by yourself, you can also customize the
ARM/DISARM to any switch by CLEANFLIGHT CONFIGURATOR.
First check that all trims are neutral, the throttle stick is
ALL the way Down with the display indicating 0%throttle.
Push the SWA MIX switch to “2” position, you will see
all the LED light turn to blue color and the buzzer issues
a “B~B” sound, indicating that motors are armed.
Be very careful at this point, as pushing the throttle up
will start the motors.You can test by pushing the stick
up a little, the motors should start.
Push the SWA MIX switch to “1” position, you will see
the front LED light turn to green color and the buzzer
issues a“B~B” sound, indicating that motors are disarmed.
