Accidental CSC is very rare and hardly ever gets reported.
Here's confirmation from a DJI person:
DJI Forum|Change CSC Procedure
Despite the hysteria, accidental CSC really isn't anything to worry about.
It just doesn't happen in normal flight.
If this thread goes they way they usually do, I'd expect lots of scared newbies (but very few experienced pilots) to weigh in with opinions on how crazy the CSC feature is.
I'm tired of responding to this every week or so.
Search the forum for CSC and see what's been said a hundred times already.
This isn't my thread - but it does give me the opportunity to speak my piece even if it has been said before. In my opinion though, it hasn't been said wel enough or often enough since the emergency motor stop sequence hasn't been changed.
I'll use this thread to add my voice and my points and hopefully, like you - DJI will get tired of responding (or at lease seeing) this every week of so and perhaps finally decide to take another look at it to see if maybe there is a better way.
Personally - I don't agree that if something is "good enough", it shouldn't be improved upon. If there is an opportunity to make something "better" then it should be seriously considered. At one time, Blackberry thought they had a product that was "good enough" and stopped improving/innovating it and we all know what ended up happening to them.
So, I don't care if there are only 2 people per year out of 100,000 that crash their Phantoms by accidentally triggering a CSC shutdown. The question should be asked: "Is there a way to prevent those 2 crashes from occurring while at the same time either maintaining or improving the ability to kill the motors quickly when necessary?"
And if the answer is "No. It's not possible" - then that's fine. But if it *is* possible to improve things, then they should improve them. It may mean 2 less drones sold per year - which is not a big deal one way or the other for DJI - but for those 2 owners, it may be a very big deal!
The only arguments I've heard for not doing this is "it's not necessary" and "during normal flight, an accidental CSC would never happen". And the existence of all the other threads you mention and all of comments similar to mine prove that there are a number of customers who are nervous about the way things work today. So even if you're right - and we wouldn't accidentally trigger the shutdown - there are a bunch of us who would be less nervous and happier customers if DJI showed that they listen to our concerns and that they care - by improving the CSC process.
I don't know about everyone else - but here's the scenario I'm worried about: I'm flying in the middle of nowhere one afternoon and my 10-year old son is with me. He sees how much fun I'm having flying around and asks if he can try. There are no people or buildings around - and I'm up around 400 feet so I decide to let him try. I'm standing right there with him - so if he gets into any trouble - like too close to the trees or too far away so that we almost lose sight of it - I can step in and take over the controls to recover from his mistakes - but let's say the drones orientation is backwards - it's pointing towards us and now left is right and right is left. The drones not responding to how my son thinks it should and he panics - pushing the sticks all over the place. Just as i try to step in - he accidentally hits on the CSC sequence and the bird drops from the sky. Now I'm on the hook for a repair or replace fee because DJI insists on using the sticks for that feature and are not willing to look for a safer combination.
So what should I do to avoid/protect myself from the above?
- purchase the CSC locks?
- not take my son out with me?
Why do the people who are not affected by this potential problem seem to be so dead set against DJI even looking into the possibility of something better? - - and possibly providing us all with a solution/improved mechanism. so that we can feel protected ALL the time instead of just most of the time? How does it affect you if they add a mode in which I can change my emergency stop process to use different buttons? You said you're getting tired of replying to these concerns every week. But why reply at all? We have a valid point. It's been proven that it can be triggered accidentally? Even if it is only a risk for new pilots during a panic attack - if an accidental triggering can be avoided - lets ask to have it be avoided....
