Basic Theory
BABY SHARK 260 VTOL features a highly advanced aerodynamic design. It is made of high density
composite material, which features high strength and very light weight. BABY SHARK VTOL adopts quick-
detach design which makes the plane easy to set up and transport. The fuselage also has big inner space
to hold flight controller, batteries or other equipments.
BABY SHARK can take off and land vertically in a small area, and fly like a multicopter. Self weight(no
payload, no battery) is 5.5kg, and max take-off weight is 12kg, the stall speed of the BABY SHARK is
15m/s-16m/s, the highest speed is about 100km/h. In this Baby SHARK VTOL plane we suggest to use
two 6S 5000mah lipo batteries for lifting motors, and 30000-40000mah Li-ion battery for cruising motor
and propeller, so except the battery, motors, ESCs, propellers and other necessary equipments still has
1.5kg payload left for zoom or mapping cameras. BABY SHARK can perform most tasks like long range
inspection, survey and mapping etc. This plane is painted in grey color, and if you need other colors, we
also can customize the color for you.

5. Connection completed.
Although the accelerometer was calibrated already for the PNP version before shipping, please calibrate it
again since it might be affected in the transportation.
Under Initial Setup, select Accel Calibration from the left-side menu. Mission Planner will prompt you to
place the vehicle each calibration position. Press any key to indicate that the autopilot is in position and then
proceed to the next orientation.
The calibration positions are: level, on right side, left side, nose down, nose up and on its back.
1.Calibrate the Accelerometer
Click this button to begin accelerometer
calibration.
This accelerometer trim can be used
to level the HUD horizon.
1.It is important that the vehicle is kept still immediately after pressing the key for each step.
2.The level position is the most important to get right as this will be the attitude that your controller
considers level while flying.

Onboard calibration produces better results.
2. Compass Calibration
Baby Shark VTOL uses high sensitivity compass and it has to be re-calibrated when fly in a new place.
Enter the compass setting page and click”start” , hold the plane and rotate it in order to hit all directions on
a sphere to calibrate the compass, when it’s done, a new offset would be given to the flight controller, and a
reboot is necessary.
3. Radio Control Calibration
Calibrating each of the transmitter controls/channels is a straightforward process - simply move each of the
enabled sticks/switches through their full range and record the maximum and minimum positions.

5. Calibrate the Airspeed Sensor
It is critical that you calibrate airspeed meter to ensure that it is working correctly, and ensure that it is
correctly zeroed.
After you start up APM on your aircraft you should wait at least 1 minute for your electronics to warm up,
preferably longer, and then do a pre-flight calibration of your airspeed sensor. Your ground station software
should have a menu for doing this, usually called “Preflight Calibration”. You need to loosely cover your
airspeed sensor to stop wind from affecting the result, then press the button. The calibration will take a
couple of seconds.
Choosing that action will re-calibrate both your ground barometric pressure and your airspeed sensor.
Next you should check that your airspeed sensor is working correctly before takeoff. To do that you should
blow into the airspeed sensor and make sure that the "AS" airspeed sensor value in your HUD rises as you
blow into it.
6. Check the Two Batteries Voltages
If you find the voltages are not correct, Enter the voltages according to the hand-held volt meter in the
“Measured Battery Voltage” field, Press tab or click out of the field and the “Voltage Divider (Calced)” value
will update and the “Battery voltage (Calced)” should now equal the measured voltage.
7. Check Before Flight
(1) Connect the internet and
load the map.
(2) The plane direction should
be same with its direction in
mission planner, if not, please
calibrate again.
(3) Check plane status, altitude,
voltage airspeed meter working
fine.

Test Flight
Before the first flight, it’s suggest to check if every component is well connected, Servos working properly,
motors spinning to the correct direction and all control surfaces are moving to the desired directions.
It’s suggested to use 3 modes, Cruise, Qhover and Qloiter as the labled modes on a three position switch.
It’s suggested to do the first flight in a very open area with no buildings or big trees around, and a flat taking
off area is necessary.
Use the Qhover(or Qloiter) mode, start the motors by pushing the rudder all to the right with the throttle at
the lowest position, the motors should start to spin, gradually increase the throttle until the plane is ready
to lift from the ground, move aileron, elevator and rudder stick gently to check if the plane is moving as
desired.
Continue to push the throttle until the plane is lifted from ground, it may swing a bit since there should be big
airflow hitting the wing, lift the plane to around 3 meters and try to fly it as a multicopter, it should not be a
problem for anyone who can play a multicopter.
When you are familiar with all controls, lift the plane to at least 50m from the ground and make sure there is
not obstacle in front of the plane.
Switch it to Cruise mode, the Baby Shark VTOL rear motor should work, once the speed is reaching at least
16m/s, the multicopter motors will stop spinning, then the Baby Shark is now transferred to fixed wing.
It’s also suggested to active the short and long failsafe, the default action is respectively CIRCLE and RTH.
So in case the plane lose RC control, it will go back all by itself.
You can fly a while and see if the plane could go straight, if you find the plane is tilting left for example, don’t
try to trim the aileron with your radio, the trim to aileron(SERVO1) must be done in parameter setting. (If
the elevator trim is necessary, please trim the SERVO2 and SERVO4 at the same time with the same trim
amount.)
GCS FAILSAFE disabled as default setting for DA16(S) radio or the control range will be greatly
affected.

If everything goes well, you can try to land. First, reduce the altitude by pushing forward the elevator and
when the altitude is around 50m above the ground, switch to Qhover(or Qloiter) Mode. Then become a
multicopter again, then you can land it just as a normal multicopter.

Autopilot
After the first flight, you can try to do autopilot.
You can choose to take off and land either by manual control or automatically.
To use automatic taking off and landing, you can change the first waypoint to VTOL_TAKE OFF, and set an
altitude like 50m for this action, then set the next waypoint a bit far (like 100m ) from the first waypoint, the
Baby Shark will take off as a multicopter, when it reaches the wanted altitude, it will switch to fixed wing and
fly waypoints or missions like a fixed wing.
The VTOL landing is also the similar, you can set the last waypoint to VTOL_LAND, but it’s suggested to set
one waypoint which is around 100m from this one, since the plane will try to turn to multicopter before the
last waypoint, if the waypoint before VTOL_LAND is too far, the Baby Shark will finish the final distance all in
multicopter mode, the power consumption in mutlicopter mode is 5 times more than in fixed wing mode.
Q_RTL is enabled as default,if the VTOL land command is not added, then the VTOL will go back to
HOME position and home altitude(default 50m)and performs automatical VTOL land.
