In this chapter, we have explored the reasons to use turnkey systems. We also learned that there are pitfalls in choosing less expensive brands. Furthermore, we explored that some of these pitfalls are dire consequences indeed. It boils down to a choice: do you save a few bucks in the beginning with a fly-by-night manufacturer and risk getting sued by a crash victim (best case) or killing someone (worst case); or do you shell out more cash and get something reliable? Is there really a choice when choosing a turnkey system?

There is another option in saving some cash up front: building your own multicopter. In the next chapter, we'll discuss how to build your own multicopter. This will be a very in-depth process and will educate you significantly on the math involved and just how to tune a proper machine.
