Food for thought.
People that buy a consumer drone that can only see a dollar sign ($$) flitting around the sky should take a step back. They aren't prepared to be participating in RC aircraft activities. Until you are very good at aircraft control, providing control inputs to maintain full control of the aircraft before the aircraft needs it, you will eventually crash. Those that react to what the aircraft does instead of establishing aircraft attitude and position before the aircraft does something are "behind the aircraft". For what they are and the advanced systems that control them, drones are extremely easy to fly but you still have to be competent and have confidence in your ability. Our systems are also very cheap in comparison to fixed or rotary wing RC which are at very high risk every time they are flown but those lacking experience spend lots of money over and over replacing them after making a single mistake in control input.
If you are not prepared to lose the value of an aircraft you are not ready to participate at that level in this activity. If your fear of losing the money spent is controlling your every thought and action the tension generated by such a mental state places you in a position where a crash is pretty much assured. Rare is the person that doesn't crash an RC model. Unheard of is the person that has never crashed, unless they have never flown. Everyone has their own comfort zone for different things but where RC aircraft is concerned that comfort zone is defined a few different ways. The first is what you can afford to lose. If you cannot afford to crash an aircraft and immediately replace it with another of like kind you are trying to do something you cannot afford to do. You need to be flying something cheaper where crashing it will not devastate you or your wallet. A second comfort zone is in your personal ability. Those with little or no experience should never, ever, be flying a machine costing more than a couple hundred $$. Someone new to this stuff is going to crash, and they will do so often as they learn how these things fly and develop their hand/eye coordination, depth perception, and become familiar with the transmitter controls. Crash something cheap, not the good stuff. When you crash don't instantly blame the aircraft. Odds are high it was you, not the aircraft, that caused it. Take a little time and review what you did, how and where you did what, the conditions surrounding the crash, and review how the system is supposed to work and how it was working at the time of the crash. Did it fall out of the sky? Be honest, was the battery really installed properly? Did you crash while landing? Think real hard about what your fingers were doing when it happened. Did it fly away? Hmm, did you have control but fly it the wrong direction because it was too far away, or experience a GPS interruption and elect to try using RTH after the GPS failed. Lots of problems are generated by the operator.
We do not "invest" in a multirotor. We buy them for our pleasure. They depreciate 50% the second they are shipped to us and depreciate further as we use them. We will never be able to sell them for more than we paid for them. Investments maintain value or appreciate, multirotors don't. Any "investments" are the ones of time and experience that increase your skills with flight control, system understanding, and in development of your photographic skills. If you can't have fun while flying a multirotor, try something else. Even something challenging and expensive can be enjoyable if the mindset is correct for the activity, but always be prepared for a crash.
Every RC aircraft has an expiration date, but that date was not provided when you made the purchase. I don't know that we ever fully own one but we get to have and enjoy them until the earth reclaims them.
