The effective use of UAVs in agriculture, especially crop-spraying drones, requires a more extended flight range. Batteries currently limit a drone’s flight time since purely electric drones tend to consume more electrical energy with their higher payload capacity. For this reason, the present project proposes the improvement of an Agras MG-1P octocopter drone batteries’ load supply through a load system consisting of a double-cylinder VVRC RCGF 70cc combustion engine and a KDE10218XF-105 brushless motor as a generator. The brushless motor operates as a generator since it weighs less than an alternator or generator. The weight is significant, and the octocopter can stay longer in the air. This project aims to increase the Agra MG-1P Octocopter UAVs flight time by more than two hours, as well as its payload, having a 9 l variable load of fumigant and a 4.4 kg load of added components, which are enough for spraying operations or FAP (Farm Agroforestry Planning) in Peru.
