Precautions before flight
1.
If this is your first time flying a drone, please read this manual thoroughly and watch the
instructional videos on our YouTube, Wechat channels and on our official website
swellpro.com.
2.
We recommend taking professional training and guidance. When flying, select an
environment appropriate to your skills. Check all calibrations and choose a large open area
to practice.
3.
It is advisable for all drone pilots to become familiar with flying in ATTI mode in case of
GPS or magnetic interference, which can interfere with drone controls.
4.
Although the SD4 is waterproof, do not fly in fog or if the wind is very strong or gusting
above Beufort Force 8.
5.
Select an open place or water surface as an ideal flying site.
6.
Flying between or near large steel buildings could adversely affect the workings of the
compass and can adversely affect or block GPS and control signals.
7.
During flight, try to maintain line of sight with the drone, keep away from obstacles and
people.
8.
Avoid flying near areas of high electromagnetic interference such as power lines or
communication towers to minimize the risk of interfere with the remote control of the
drone.
9.
Fly below 4000 meters above sea level as environmental factors including air density and
wind shear reduce the performance of aircraft and therefore also propulsion batteries.
10.
Before flying in low temperatures, warm the battery to ~25c to maximize flight time.
