Currently, at least two people are needed to take off the drone. One
person controls the drone, while a second person connects it to the
ground with a conventional fishing line. The fishing line is
connected to the body of the drone and is wound over the fishing
line on a fishing reel. As the drone increases in altitude, it can
unwind the line on its own with little resistance when the reel is
"open". If the drone sinks, the person operating the fishing rod
must reel in the line so that it does not get caught in the rotor.
It is important to always point the tip at the body of the drone and
ensure that the line is guided outwards between the rotors,
especially during take-off and landing.
Regarding the flight
time and the power supply, it is assumed that the autonomy in flight
is about 30 minutes. The maximum autonomy of the remote control is
six hours, much less restrictive than that of the drone. Between
each flight, the drone must land and the battery must be charged or
replaced. The battery recharge time is about 1.5 hours.
