So I was on flight 6 with a new inspire 1 everything was working fine.
Compass was calibrated pre checks done full battery antenas set flit well for about 4 minutes and then I was doing some 360 degrees turns while decending and I got a Facebook message on my iPhone 5s. but also I may have put both toggles down and in. In this momment all motors stopped and the thing plummeted into the river. .

Is it possible to shut the motors off mid flight with landing gears up???? If not what else could cause all motors to just shit offffff??????


Raahhhhhhhh.   Help please

wow, that sux, sorry.  it sounds like you might have shut the motors off with the csc command(kill switch) but I would think you would have to be going backwards and downwards corkscrewing to do this.  both sticks in and down will shut down the motors.  any chance of recovery?

Both sticks down & in is the CSC to start/kill the motors. If you did this and held it for a sec it will kill the motors whether in flight or not.

I do really steep spiral dives all the time, but it's left stick full back & a little in, (right) & right stick full forward, for a right turning spiral. You'd be flying backward & crabbing left while yawing right & descending with the sticks in the CSC position.

Sorry to hear about your loss, but it sounds like you may have cut off the motors. If the flight log recorded to your IPhone you can go to the user center in the pilot app & replay it, with the option to show stick position.

There have been some complaints that you should not be able to do this in flight, but I think it's there for safety purposes, in the event you need to drop the bird out of the sky in an emergency, shut the motors down in the event of a crash into a tree, etc.

One possible solution would be for DJI to program the firmware to require the sticks be held in the CSC position for a solid 3 seconds. Right now it doesn't quite do it instantaneously, but you don't have to hold them there very long to stop the motors. Lengthening the time to a full 3 seconds would keep it from happening accidentally if someone did it momentarily inflight. But 3 seconds would seem like a long time if your Inspire were caught in a tree or something else with the motors burning up or causing damage while you're trying to shut them down via the CSC.

There are no manuvers in normal flight where the sticks should be in the position, but I can see where you might flinch in the surprise of receiving a FaceTime call during flight. Putting the phone in Airplane mode will avoid that. Again, sorry to hear you lost your Inspire. Is the water to deep to dive for it? If you recovered it, let it dry & sent it back to DJI, maybe they could salvage some of it.

I agree with Woodie, Sounds like you accidentially shut the Inspire down. It happens. Were you able to retrieve the Inspire and get it to run again after drying it out?

Let's say you are at 400 feet and CSC to kill the engines. They shut off and it drops. If you do the same thing with the sticks will they restart in mid-flight?

Theoretically yes, but don't know if anyone has been game to confirm it!   


Hectic, very sorry to hear about your loss, it's our worst nightmare anytime we fly!    I was flying over the ocean yesterday and was freaking out every time I went out.

Yeah, they'll start back up, I've done it with my Phantom 2 but not willing to risk it with my Inspire.

I've disassembled the whole thing and there is electrolisis on some of the circuit boards :/ I'm hopping I can buy replacement parts or a wrecked inspire, but no luck as yet.  The camera components look fine throughout so it may be ok :/ time will tell basically going to be a full rebuild

Thanks for the input guys pretty costly pilot error, dam it why did I have to try and be tricky.  
I think I'll buy another and use this one for parts in case of future crashes. (Touch wood).

I dove for it and the thing was still flashing lights but most of the circuit boards are toast it won't fly again without a hell of a lot of work. Anyone got a smashed up inspire I can salvage parts off.?????  

Btw thank you guys for confirming my incompetence as a pilot hahahaha bastards FML. Hopefully this helps make others aware to not do the same thing cause it really sux a huge bag of dicks watching it go into the drink.

I thought I was in a matrix glitch for a minute after the splash.

Some guys have done some really nasty things to their copters and DJI has rebuilt them at surprisingly cheap prices! At least that's what some have posted. You may want to see about a repair? The frame and hardware are more than likely ok, electronics can be fairly cheap to fix unless you require extensive replacements?

I just spoke with a guy recently who accidentally CSC'd his craft midair with the sticks down and OUT.  I thought it was just down and inward, but I haven't tested this on the ground.  Maybe another position to watch out for while flying.

Yes, CSC is down and out as well as down and in. They have even modelled this in flight shutdown and restart in the simulator. I believe that the left hand full down will not shut down the engine in mid-flight however, just the two CSC positions. I suspect that DJI may really come through for you if you send it off to them. As we keep reading in the news airline captains also shutdown engines by mistake in flight with similar consequences.

I looked at my flight record and was confused because I also put the sticks down and out wow wow dji should fix this issue I think. Too many ways to turn it off.

Made test in SIM on this.
Yes, motors start again with another CSC.
But the bird drops +/- 50meters between 1st. CSC and 2th CSC followed with left stick full up
So no chance recovering if you fly lower than 50meter (150feet)
A 3sec delay on the SCS as woodie suggests would make it almost impossible to recover.

Dundee, I was thinking the 3 second requirement would only be to kill the motors. They should start instantly with the CSC when they're off. Seem like the software should be able to know if the motors are on or off. If on, you have to hold the CSC position 3 sec to shut them off. If off, the CSC starts them instantly.

Yes woodie, i now totaly agree with you.

There was even a discussion here to activate or deactivate CSC in the app settings.
A solution to keep everybody happy.

But the 3sec delay when motors on, and 1sec delay when motors off is better.
I will report this in the Beta-program.
Thanks

Or maybe the option to have the sticks down with a combination? (in-out-in OR out-in-out, within 1 second?)

Just an idea, there might be someone who needs the 'down in-out-in' for a very nice move I don't know yet ;-).


I haven't flown any 3D with the Inspire and I am thinking of keeping it that way.
I'll leave that up to Curtis Youngblood .

The CSC should require the autopilot to also cross check with the z-axis accelerometer before shutting off the motors to verify it is on the ground.  It's stupid to have this option while flying.

Yes, tested by me

What about just a flippin' button on the remote that you hold for 3 secs (like the "return home" button).

Yesterday was my first flight with the I1. When I landed, I did both sticks down and in to shut down the motors. By the time I was getting visual clues that the motors were shutting down, they were getting ready to spool back up, (cause I didn't release the sticks at the proper moment).

I REALLY don't like this at all!
The very first thing I have ALWAYS done after walking up to a powerful bird after landing was to disconnect the power, via switch or unplug.
I need to know that there is NO WAY that thing could start back up while I pick it up or carry it away.

Please DJI, we need a dedicated "kill switch" in the event of an emergency, (not create one).


(when your "accidental" kills quadruple the number of "intentional" kills, something NEEDS to be done, anyone agree?)

All you have to do to shut down the landed aircraft is hold the Throttle stick down for ~3 sec.
CSC is not required.
Then, you won't confuse the shutdown and startup CSC.
This shutdown feature has been in the DJI FC's firmware for some time...

CSC has been DJI's chosen method of start/stop motors from day one.
Thousands of pilots have flown thousands of aircraft with it and not had problems.
I don't suspect DJI will be changing it...

In flight, CSC = drop as fast as possible + rotate (CW or CCW) as fast as possible + fly back and to the right or left as fast as possible.
Just not something the average pilot would want/need to do...
Can you do it?
Sure
Going at highway speeds do you turn your steering wheel to the right or left as far as it will go?
Can you do it?
Sure

Results for both "Can you do?" questions are the same...

Yes that does work, I've done it but was not able to regain control of the bird.

Was it in really cold temperatures that day?

A small E-stop button, somewhat hard to depress and maintains, with a bright red LED light would solve all this.  It's the industry standard in all automation.  You would know when it's depressed, could see that clearly, and could reset and restart if done quickly since you can clearly see what happened.  Located correctly on the RC it would only be pressed deliberately.   

Sorry to hear about the crash! Gezzzz that truly sucks!

Sorry for your loss!

hope you can get this repaired by DJI at a reduced cost.

I do not like the CSC feature the way it works today. I hope this can be improved somehow while maintaining the safety of being able to shut the aircraft off.

@RichJ53 I m sending mine in to DJI today so we'll see how much it cost to repair the bird after the CSC command.  Honestly I understand the CSC but there should be an audible warning alerting you that you are activating it.

My bird did reactivate midflight about 100 ft up but it was titled to the right.  I had no idea that  i had activated the CSC.  So i was throttling upward which was causing the bird to go to the right instead of upward,

Its a tough 5k lesson.  I hope DJI implements an audible warning for this safety feature as this would alleviate accidental activation.  I hope you guys learn from my mistake.

Shouldn't be something you have to learn from..... just boggles my mind that this has not been "adjusted"
FYI I have seen CSC prevent plastic pieces you can install on your radio.... might be an option for the new people doing some reading.

Yes, we shouldn't be learning this way!! And I hope they treat you right. Keep us informed and best of luck to you

Why not just add another button you need to press to activate the CSC?
Like both C buttons. You need to press C1 and C2 with the sticks down in/out. This combination is nothing you do in flight - even unexpected.
