Analysis of Preliminary Design Requirements of a Heavy Lift Multirotor Drone for Agricultural Use 	2017	6	.pdf	application/pdf	3101	91	38	A possible choice relies on using a Ready To Fly (RTF) UAV, but rapid changes in components and a fast evolution of the performance of engines and batteries allow possible updates of the existing UAV using aftermarket part to increase the flight envelope, a particularly interesting feature for heavy lift drone if a proper design method is adopted. Such performance can be considered satisfactory not only to fulfil imaging and crop diagnostic missions, but also to perform more challenging one like plantation or pesticide distribution. 4. Conclusions Integration of components is not a straightforward task due to a lack of an integrated theory, application is challenging since it requires expert knowledge in aerodynamics and control theory, and the commercial development of heavy lift drones it is still today limited to few companies, often with export limitations on aircraft and sensors (i.e. frequency of IR sensors) due to military implications.	cache/cet-1369.pdf	txt/cet-1369.txt
