Well, if it were me (and it's only my personal opinion - everyone has to satisfy themselves and do what works for them) - I would get the old props and maybe another pack of prop locks while you can get them.
I personally prefer the redundancy a threaded self tightening prop AND a prop lock give you...... but that's me.
FYI - I have today called 5 dealers and only two had stock of the old props..... I have now cleaned both those dealers out. Assuming I do not go cutting grass or trees or shrubs etc I would hope I have sufficient 'old' props for the life of the machine
I'll argue with you on this
. In my opinion, the odds of this system failing are about the same odds that an esc or motor will fail, 200 flights is a lot of flights (in the real world, as you mentioned you reside) and to put this in perspective numbers wise, if the average inspire user had 6 batteries and flew every day, the cam system would last over a month, odds are you would be replacing your props before that.The prop locks are considered consumable as well (DJI just didn't inform you like they did with the cam system) as you squeeze them to install they are getting used, the stress of them being installed with props (and in use) will cause them stress to the point that they could fail if you aren't paying attention to your install and very well fail mid flight, just like the cam system, if you aren't paying attention to how the prop is installed and checking that, yes it will fail on you. The cam system is inexpensive so there's no reason to not have a complete replacement set in your tool bag in the event you need to replace one or want to. To me this part is no different to replace than the wear and tear parts for your car, your computer, your bicycle, etc etc...I hope you see where I'm going here.
The picture you provided is definitely evident of crash results, to which we have no idea how the crash happened, you just posted the pic pinpointing the cam system to blame and implying to everyone here that it is faulty by design so now you got a bunch of people thinking that it sucks and will cause your inspire to crash at some point. This is also called propaganda (see what I did there) and you're building a situation that has no truth from the original poster of that pic to provide us with how it happened or even why they took a pic of the broken cam system. For all we know, it was 1 of 5 other pics of broken parts that the owner was looking to get replaced.
The funny thing is you bring up redundancy, yet there's a multitude of people on here and in the world in general (you and myself included) flying inspires and other quad based systems everyday for "professional" use. If you guys are so concerned with this as an issue, I would suggest selling your inspire and investing in a proper redundant system, y6, x8, octo, dual fc systems, batts in parallel...etc etc. Point is you can chalk this up to being "unsafe" yet your Inspire is an unsafe platform every time you take off. Every time. It doesn't matter whether you have the cam system installed or the older prop locks, it's still unsafe. All in all this boils down to the age old saying "don't fly what you can't afford to lose"
Anyway, just another point of view to look at
. I understand where you're coming from completely. While I won't be replacing my cam system until I see it necessary or until I hit 200 flights on my inspire, I totally get why others would. So don't hate on me too much.
