6. In addition, before take-off, listen to the sound of the motors and propellers. You should hear
a uniform sound from all motors and propellers and you should visually verify that STORMBEE
exhibits little to no vibrations, in other words, STORMBEE is not shaking.
7. Take-off by moving the throttle stick slowly upwards. Keep the direction and force of the
prevailing winds in mind and correct where necessary. Climb to around 2m (6ft) height above
the terrain.
NOTE Keep in mind that STORMBEE is a 2m long, 26kg heavy, multirotor and as such is less
nimble than a small drone. Although its response is quite crisp, its inertia will make it
feel like flying a jumbo jet instead of a small aircraft. The DJI A3 flight controller settings
are also set to respond less aggressive on purpose for this reason. Keep your pilot
inputs small and gentle.
CAUTION! Keep in mind that when the STORMBEE is moving forward and you set the control
sticks to neutral, thus requesting it to hover in P-GPS mode, it will have quite a long
braking distance before it comes to a hover. Both acceleration and deceleration are
set to be gentle!
WARNING!! Watch STORMBEE at all times during the flight! Keep your left-hand index finger on the
flight mode switch on top of the DJI Lightbridge 2 at all times so you can switch to ATTI
mode if something goes wrong without having to first search/feel for the button.
8. Verify on the GS Pro display that there are 10 or more GPS satellites available.
9. Keep hovering at 2m height above the terrain and check the response of STORMBEE to (small
and gentle) roll, pitch, yaw and throttle inputs to verify its responses are correct and no
position drift is present.
WARNING!! This is the point in flight at which you should and want to find out if you have
accidentally set the wrong pilot flight control mode (mode 1, 2, 3 or other) or if
something is wrong with the DJI A3 flight controller or its sensors. Therefore, keep your
pilot inputs small and gentle and be very careful during take-off and while checking the
response.
10. When using the GS Pro app, you should now see the RTH (virtual) button on the GS Pro app on
the left-hand side with the RTH altitude underneath. Tap on the altitude (text) to adjust the
RTH altitude if necessary. Be careful to not accidentally tap on the RTH button itself at it would
land the STORMBEE. You should have used the laser range finder binocular to measure the
