I disagree
No link.
Just something I read in another post here.
This is not saying that they won't last years. My P2-NV is going strong since May '14 but like all r/c toys they are not considered 'Durable Goods'.
I disagree. First, I strongly doubt DJI would even hint at such, mostly because it'd be a shot in their own feet considering that absolutely none of their competitors make no such claims. Not even makers of smaller, toy-like, semi-disposable drones. Certainly not 3DR, Yuneec or Autel.
As you said, there are lots of P2s still flying and - I'd guess - even more P3s with hundreds of hours of flawless service. The oldest P3P in my fleet (my favorite btw, even more than the I1) is 1-yr old already, flying professionally quite a lot, all the time, and is 100% fine. I feel t's safe to assume that if I don't crash too hard it'll last for many more yrs too, maybe requiring a new motor or something at some point (maybe, my P2s didn't and were sold almost as new).
They can be repaired, parts can be replaced, they can be rebuilt, improved, both Tx and AC. Even in light of issues (cracks, ESC or compass error, whatever, which other brands suffer too), they are as durable as the pilot make them, like most other durable goods. So, unless it can be proven somehow that DJI officially said something like this, or even implied, I consider a myth being spread through repetition, something totally lacking consistence.
