In order to choose for your particular needs, there are many questions that have to be addressed. For example : • What are the different types of drones and their uses ? • Is it better to build your drone yourself or buy a ready to fly model ? • What are the elements of the drone that will enable you to make the right choice ? • Which batteries to choose ? • Which remote control to choose ? A drone has to be seen as an aircraft carrying a payload. The need to align the task with the aircraft raises questions such as : • How to design its payload ? • If you are making it yourself, which 3D printer to use ? • What are the impacts of the payload on the choice of the drone and the flight route ? • How to choose components and the technology of the payload ? Finally, operation also has its constraints : • What precautions should be taken to operate in the field ? • How should you organize your tasks ? • How to set up the radio link to avoid a communication break ? • Which launch and recovery systems to use ? This book will help you answer these questions and ensure you get the most from your UAV.
