8. Operation Manual.
Basic Function Introduction :
● Inside the quadcopter :
■ A flight controller which is powered by a 32 bit MCU.
■ An integrated sensor module including accelerometer, gyro, compass &
barometer sensors.
■ A GPS module.
■ Four sets of speed controllers, motors, and foldable self-tighten CW & CCW
propellers.
■ Built-in telemetry system
● An 8 Channel radio control system has control range about 1000 meters, (depends
on circumstances).
● The 2 control sticks control the 4 Axis (Roll, Pitch, Yaw, Up/Down) flight control. A
mode switch near the middle of the bottom of the remote control can change the
stick mode between Mode 1 / Mode 2. (Mode 1: right-hand throttle , Mode 2: lefthand throttle)
● A 3-position switch, at the top right corner of the remote control, controls 3 flight
modes: GPS Hold (for outdoor), Altitude Hold (no GPS signal/indoor), and Return
to “Launch point”.
P.3
■ GPS hold - When GPS is located, this function will hold the Quadcopter where it
is. When “GPS hold” is turned on, the Quadcopter can’t takeoff if the GPS signal
is too weak. ( Suggest: the wind speed shall be under 4~5 level or lower than
15km/hr )
■ Attitude hold – The Quadcopter will hold the altitude & keep stabilized
automatically while not getting any control input from the pilot or fail safe action.
Note: the Quadcopter may slight shift in the air by wind or any un-notable
foreign force on it. “Attitude hold” is for flying indoor or without GPS located
situation. ( Suggest: the wind speed shall be under 5 level or lower than 25km/
hr )
■ Return to “Launch point” – When the GPS is located, when RTL is activated by
the pilot or failsafe, Quad-copter will fly back to the “Launch point” and land.
When RTL is activated, if the Quad-copter is lower than safe height 10m, it will
pull to 10m and process RTL. ( Suggest: the wind speed shall be under 4~5
level or lower than 15km/hr )
● A 3 position switch, at the top left of the remote control, controls 2 orientation
control modes: Normal and Intelligent altitude mode.
■ Normal - As the regular RC flight, the Quad-copter attitude & orientation control
is based on the orientation of the Quad-copter’s heading. The orange propellers
point to the front. (The picture below shows an example of mode2 )
Usually
■ Intelligent altitude mode – designed for flight beyond visual range. It uses the
vehicle’s position relative to home instead of the vehicle’s initial heading when
it was armed. This means no matter where the vehicle is, pulling the pitch back
will cause it to return towards home regardless of the vehicle’s actual heading.
(The picture below shows an example of mode2 )
In home lock

P.10
P.11
Un-fold the Quad-copter :
● Rotate two front arms forward till the end.
● Rotate the two rear arms backward till the end.
● Flip the two landing gear downward.
● Fix the landing gear by the support hook or the velcro strap.
● Unfold the propellers. (Note: if the propellers are not unfolded completely, it may
cause strong vibration and lead the take-off to failure.)
P.12
Fold the Quad-copter :
● Reverse the process of "unfold the Quad-copter".
● Use one hand to hold the main body, the other hand to “PUSH” the arm inward to
the main body. Never hold single arm while carrying the Quad-copter.
Charging the Battery :
The following descriptions vary according to different accessories.
● Connect the included balance charger to a power adapter.
● Insert the smaller connector into the charger. Check the connector pin is inserted
properly.
● Once the battery is fully charged, the LED red light will change to a green light.
● Never charge a battery when it has not had the time to cool down from the
previous use.
P.13
Battery Storage :
● Never store fully charged battery for over two days. Storing fully charged battery
overtime may cause damage to the cell and decrease the flight time.
● Make sure that the battery is kept in a cool and dry storage.
● Stabbing or disposing battery may cause fire.
Flight :
Install the Battery Pack
● Whatever the payload (Battery, Camera, … etc, anything except the Quad-copter
itself.) is assembled on the Quad-copter, the CG (center gravity) should be located
close to the center of all 4 motors for better flying performance.
● Battery should be the last payload to be installed on the Quad-copter. So the
battery installation is the final adjustment of the best CG balance.
● A single or two parallel batteries can be installed under the bottom side of the main
body. Adjust the location to get the best balance CG then secure the battery with
Velcro straps.
DOWN
● Before connect the battery, please make sure the RESET
UP
switch is in DOWN position. Then move the RESET
switch to UP position AFTER power ON and the LEDs
will light up and flash. Wait for the orange LED becoming
static ON, which means GPS signal is good and the
Flexify is ready to take off.
Arm & Disarm the Motors :
Motor arming
● The motor arming is only available in GPS and ALT-Hold flight mode.
● Make sure the propeller is fully unfolded. Pilot should keep a 5m safe distance
from the Quad-copter, and the wind speed should lower than 20km/hr.
● Pull the joysticks as the picture below and stay 2 seconds.
MODEL 1
MODEL 2
MOTOR ARM
● The blue LED on the right corner of the Quad-copter will flash once, and the
motors will start to spin in slow speed. Release the throttle stick. The motor
arming is completed.
P.14
Motor disarming :
● When the Quad-copter finish landing, move the throttle stick in low position. Make
sure the motors are spinning in slow speed; or the Quad-copter will rotate quickly.
MODEL 1
MODEL 2
MOTOR DISARM
● Pull the joysticks as the picture above and stay 2 seconds -the blue LED on the
right corner of the Quad-copter will flash once.
● Pull the joysticks till the motor is fully stopped. The motor disarming is completed.
GPS Hold :
● In GPS located situation, GPS-Hold (CH.5 at top position) flight mode will keep
the Quad-copter’s stabilization and locked at a fixed altitude, coordinate and
orientation. The Quad-copter won’t drift in the air due to the GPS lock to locate the
coordinate in this flight mode.
● If GPS is not well located, the motor will not be armed.
● If the GPS failed to locate in the air but the pilot activates GPS mode, the Quadcopter will response as altitude hold mode.
Altitude Hold :
● ALT-Hold (CH.5 at middle position) flight mode will keep the Quad-copter’s
stabilization and locked at a fixed altitude & orientation, but the Quad-copter may
drift in the air due to no GPS help to locate he The Quad-copter coordinate..
● In a no GPS condition (as indoor), it will be the only available flight mode; the
GPS-Hold and RTL will be unvalid.
P.15
Return to “Launch point”
● When the motors are armed in GPS located situation, the “launch point” coordinate
will be saved in The Quad-copter.
● Whatever how the RTL function is activated, by the flight mode switch (CH.5 at
low position)” or because the failsafe, the Quad-copter will keep at least a 15M or
higher altitude then fly back to the launch point and land.
● In failsafe RTL, the flight mode can be changed anytime when the CH.5 switch is
flipped to other flight mode. (Please beware in this kind of operation. )
P.16
Intelligent Attitude Mode :
● Usually, intelligent attitude mode is activated when the Quad-copter flies beyond
visual range.
● When the intelligent attitude mode is activated by CH.6, it uses the vehicle’s
position relative to home instead of the vehicle’s initial heading when it was
armed. This means no matter where the vehicle is, pulling the pitch back will
cause it to return towards home regardless of the vehicle’s actual heading.
Intelligent attitude mode:
Controls are applied based
on the Quad-copter’s GPS
position relative to home.
The orientation is not
updated when the vehicle
is within 10m of home.
When the pilot fly the
Quad-copter to the right,
wherever the Quad-copter
nose points, the Quadcopter will fly to the right
of the launch point; when
the pilot fly the Quadcopter to forward, the
Quad-copter will fly away
from the launch point.
Fail Safe:
Low Battery Fail Safe
● When the battery voltage reaches to failsafe voltage setting, all 4 arm LEDs will
blink to warn the pilot, and the Quad-copter will activate RTL mode automatically.
● Note: The Quad-copter will activate RTL mode automatically; but the voltage
is possibly too low to finish landing. Usually pilot has 1 minute or less to finish
landing.
P.17
● We suggest pilot to activate ALT-Hold (CH.5 at middle position) and land manually.
● Please reserve about 30% power for return and landing. Do not use the low battery
fail safe as a flight time alarm – it will decrease the battery using time; there is risk
that the Quad-copter couldn’t make it to launch point.
