A limiting factor in further development of the electrically driven mulicopter type UAVs is their low flight endurance - up to 1 hour with a real payload. It depends, on the limited specific energy of the batteries that multicopters carry on board. One of the solutions to the problem is the use of an energy source with higher specific energy - gasoline. Through it, electricity is generated on board, which feeds the drive motors and the payload. In theory and in practice, hybrid drives allow the flight endurance of multicopters to reach 4 hours.
