Preflight Checks
1. Verify that all components are included, without damage and the airframe is with no
deformation.
2. Verify that propellers and motors are installed correctly and stably.
3. Ensure that propellers do not scratch against frame ducts and motors spin smoothly.
4. Verify batteries (of quadcopter, remote control radio transmitter, and FPV goggles)
are fully charged.
5. Be sure pilot is familiar with all flight controls. (Refer “Remote Control Radio
Transmitter”).
6. Always keep a safe distance in all directions around the quadcopter (1 meter or
more) when having a test-flight. Operate the quadcopter carefully in open space.
Quick Start Guide
Quick Start
Before flying, verify that the remote control radio transmitter is successfully connected with the
quadcopter, all basic controls are functional, and the quadcopter can be taken off normally.
l Step 1: On the remote control radio transmitter, set the throttle joystick and four
switches on the top to the lowest position. Long press the power button on the
remote control radio transmitter for 5 seconds until it beeps three times, then
release. The remote control radio transmitter power indicator will quickly flash red,
then remain blue, which means powered on.
l Step 2: Install the battery into the battery mounting slot under the quadcopter. Ensure
that the direction of the battery interface and that of the quadcopter power cord is
consistent. Connect the quadcopter with the battery, then place the quadcopter on
ahorizontal surface. Wait 3-5 seconds until its status LED lights to change from
flashing blue to solid blue. This indicates that the initialization of the quadcopter is
complete and the quadcopter is connected successfully with the remote control
radio transmitter.
l Step 3: Move switch SA up to arm the quadcopter. The throttle joystick must be at the
lowest position or the quadcopter will not arm. The motors will spin slowly. Move
switch SA down to disarm the quadcopter and the motors will stop spinning.
The completion of these steps verifies that the quadcopter and the remote control radio
transmitter can work normally, and the following flight operations can be continued.
Flight Operation
l Step 4: Re-arm quadcopter (step 3). Motors will spin at a low speed.
Throttle (left) Joystick:
l Up/down controls rate of ascent/ descent.
l Left/Right controls counterclockwise/ clockwise rotation.
Direction (right) Joystick:
l Up/down controls forward/ backward.
l Left/right controls left/ right.
Before flying with goggles, it is recommended to practice and become familiar with the controls
and sensitivity of the joysticks by following the above-mentioned operation steps.
Caution:
1. Find a suitable open place for the first flight.
2. Push the joysticks slowly, especially the throttle joystick.
3. If the quadcopter becomes out of control or collides with objects, disarm the quadcopter
quickly (push switch SA down) and motors will stop spinning.
l Step 5: Land quadcopter steadily and keep it disarmed (push switch SA down), as
shown below:
l Step 6: Disconnect and remove the battery from the quadcopter. A long press of the
power button on the remote control radio transmitter will turn it off after three
beeps.
First Person View (FPV)
First-person view (FPV) is the real-time transmission of the camera image to FPV goggles.
l Take out the goggles, install the headband;
l Slide the power switch to the right. The screen lights up and the VR02 goggles are
turned on;
l Long press the “S” button for 1 second to turn on the fast frequency search function.
After 3 seconds, a beep will sound and the corresponding FPV cross-machine
screen is displayed in the goggles, indicating that the frequency search is
complete.
On-Screen Display (OSD)
After the frequency search, flight information and FPV images will be shown on the display. This
information is called On-screen Display (OSD), as shown below:
About OSD information:
l The flight status of the quadcopter is displayed in the center. DISARM indicates locked
status. LOW VOL indicates that the battery voltage of the quadcopter is low. RX
LOSS indicates that the quadcopter has been disconnected with the remote control
radio transmitter;
l Status of the quadcopter is displayed in the bottom of the screen, including the
receiver protocol, quad battery voltage, flight time, flight mode, and speed
threshold. chg
Flight Modes
The flight mode is displayed in the lower right corner of the flight screen, corresponding to the
flight mode of quadcopter. Pilot can choose different flight modes according to different flight
environments and their flight control skills. chg
1. Normal Mode: When the quadcopter ascends, center the two joysticks at the same
time, and the quadcopter will maintain at a fixed point in a horizontal attitude. The position
of the direction joystick controls the tilt direction and tilt angle of the quadcopter. The
quadcopter has an auxiliary flight function that can assist in adjusting the altitude and
horizontal position, which makes it easier for pilot to control. N MODE is displayed in the
OSD. chg
2. Sport Mode: When the quadcopter ascends, pilot needs to operate the throttle
joystick to control and adjust the altitude of the quadcopter. The position of the direction
joystick controls the tilt direction and tilt angle of the quadcopter. When the direction joystick
is moved back to the center, the quadcopter will return to a horizontal attitude. The
quadcopter has no auxiliary flight function, which makes the operation relatively difficult for
pilot. S MODE is displayed in the OSD.
3. Manual Mode: When the quadcopter ascends, pilot needs to operate the throttle
joystick to control and adjust the flight altitude. Position of the direction joystick controls the
roll direction and the roll speed of the quadcopter. The quadcopter will maintain its current
attitude when the direction joystick is moved to the center. The quadcopter has no auxiliary
flight function, and the flight attitude and altitude are completely dependent on the pilot to
control the quadcopter by the remote controlradio transmitter, which makes the operation
very difficult for pilot. M MODE is displayed in the OSD.
The flight mode is selected by a switch on the remote control radio transmitter. For more details,
please refer to the chapter “Remote Control Radio Transmitter-Switch Functions”.
Caution: Please keep the flight altitude within 0.3-3m when it is in Normal Mode. This can keep
the quadcopter fly stably. The outdoor flying height of the quadcopter should not exceed 3m as
far as possible.
Battery Charging
Each battery provides 4-5 minutes of smooth flight. When LOW VOL is displayed in the OSD
flight interface and the status LED on the quadcopter changes to flashing red, which indicates
that the battery is too low and needs to be charged. Charging steps are as follows:
l Plug the charger into the Type-C port through USB cable;
l Connect one or two batteries to the port on the right of the charger and the charger’s
LED turns solid red when charging;
l When the charger’s LED turns solid green, charging is complete.
Two batteries can be charged at the same time. Charging a fully discharged battery takes
approximately 20 minutes. When the battery is inserted into the TEST port and the charger is
not plugged in via USB cable, the current battery level will be displayed. 4.30 indicates a fully
charged battery while 3.30 indicates the battery is low.
