I respectfully disagree.
Reputable manufacturers understand the value of support (life cycle) after the sale is a major incentive toward future sales. Growing one’s fleet is not always defined as “chuck the old and replace, plus add, new models.”
Personally, I hang on to stuff. If something can be upgraded, the better. But I realize it is necessary, and often desirable to add completely new units.
The personal computer environment is a great example. While I make use of the old stuff (repurpose), I relish building new systems, with the latest technology, and watching them fly. (Photo/video processing, for instance.)
It would increase my confidence in Yuneec (to name one sUAS player) if, by example, we continue to see parts availability for older craft, up to a reasonable obsolescence time period, of course. It is unreasonable to expect a never ending support life. Customers pay, one way or another for such support. At the same time, increasing capabilities by developing new and/or upgraded models is not a bad thing, for a manufacturer as well as consumers.
Imagine if automobile manufacturers did nothing but upgrade existing “shells”. No offense intended toward nostalgia lovers, but think about it. We could all be using satellite radio, 16 channel sound systems, state of the art navigation, maybe even fusion-o-matic propulsion systems, while the body style was still the old fishbowl AMC Pacer!
Yes, an extreme example, but still points made.
