Finding out the simplest way, in a practical and technical sense, for me to build and fly my own, reasonable safe, flying machine has been a long term ongoing research type of project. Not always progressing in the front, but never seizing completely either. In the search for the answer I have built various structures to try out the actual capability of the concept at hand. Some of these concepts and my thoughts of the outcome of the tests I have conducted are covered in Part 1, “Early trials”.
In Part 2 various aspects of building large multirotors are dealt with such as the challenge of scaling up a R/C drone to man carrying size and what to consider if you are using 3D printed parts in your design.
Once I settled for the multirotor approach I started out with what I assessed would be the lowest cost setup. That is the main reason for the two first versions being powered by 2-stroke engines, which is covered in Part 3, “Multirotor V1-2”. After a year and a half, I was finally able to conduct a short series of manned test flights with the gas-powered version, but the craft lacked almost all flight characteristics and features I was looking for in such a vehicle.
Since I by now could afford to try an electric approach, which turned out to be a success, I went ahead and did just that which is covered in Part 4, “Multirotor V3” (the chAIR).
