Generally speaking, what percentage depreciation do you usually apply to a quad once it becomes used? I know somebody is going to say something is worth what somebody will pay for it, but be real. I don't care how new, or hardly used something is...used is used and possibly abused.
Sorry to say but there is no real metric. Camera wuadcopters tend to retain value better simply because they go through lighter usage. Batteries loose value fast because you are ALWAYS taking a risk on them, racers more so than camera platforms again.
Depends on how used, how bad the buyer needs it, and how fast the seller wants to get rid of it for. A lot of variables come into play to produce the final result of it is only worth selling for the price you either stand to make money, or stand to loose an amount you are conformable with. For the buyer a lot more factors come into play, including how bad they need it, how available the same thing is new or used, and even their impulse buys.
Wish I could give a more reproducible metric, perhaps people who do a lot of sells could provide you with one, but I'm unable without a case by case basis.
... Agreed, there's no accurate way to gauge something like a "depreciation rate" when it comes to this hobby.
