If memory serves thereâs a parameter you can change that stops the inverted shutoff, itâd be interesting if that also allowed inverted startup as well for when the aircraft is freefalling.
The risk there is the drone then thinks up is down and powers itself at high speed into the dirt.

Pretty sure, at least in the video I posted, itâs more efficient to invert and thrust at high altitude, to make the most of the battery. That way youâre not wasting energy in prop wash

Wow! That videoâs six years old! n I didnât know it was a âthingâ! Thanks, @milkmanchris, @OzoneVibe, @notveryprettyboy, @Jellan. Iâm stunned!
Thatâs discussed in the video.
Here is explained and on a video at; Restarting the Mavic Mini 2 Mid-Air after CSC | DJI Mavic, Air & Mini Drone Community
The problem lies in whether or not the drone tumbles in the free fall.
If it tumbles then there is a chance it may exceed the angles of tilt within which the drone will permit the motors to restart. So, if you are going to try it, be sure to start HIGH up over somewhere empty of people, property and animals.
Switch the CSC response mode to âanytimeâ. Switch the flight mode cine (slowest flight speeds and lowest angles of tilt before the motors stop etc.) and put the sticks in the CSC position and hold them there. The motors will stop within either 0.7 or 1.7 seconds.
As soon and they stop release the sticks and let them centre.
Look at the screen to see if the drone is tumbling or apparently falling in a flat spin.
If it is tumbling then put the sticks into the CSC position and probably hold them there. If the screen shows the drone stop tumbling release the CSC position IMMEDIATELY and give the drone full throttle. If the drone continues to tumble then I do not know if it is better to try releasing the sticks and then put them back into the CSC position or just hold them in the CSC position and pray.
To some extent you can test what will happen by HOLDING the drone in your hand WITH A FIRM GRASP and wobble the drone to near 90 deg tilts WHILST holding the sticks in the CSC position. MAKE SURE you fingers, wrist and face will not be hit by the props. If the motors restart the drone will fight you, be prepared for this. You would do best to stop wobbling your hand, release the sticks and then hold the throttle closed, that should stop the motors after a second or so, if it doesnât then tilt the drone to 90deg or so. DO NOT release your grasp of the drone UNTIL the motors have stopped, there is no telling where it might go to if you release you grasp with the motors fighting you.
If the screen shows the drone to be falling level or in a flat spin then you are likely to be in a better position but restart the motors with the CSC position fairly quickly, the free fall speed is likely to be quite fast. If the drone was falling in a flat spin then a motor restart will stop the spin, release the sticks as soon as you see that happen and then give the drone full throttle.
The reason I suggest full throttle after a restart is because the motors may restart at idle and idle will not halt the fall. I had this happen with a Phantom 3 and it took me a second or so to realise what had happened. Incidentally the freefall speed of my phantom was, from memory, between 14m/s and 16m/s. I suspect the Mini 2 is more intelligent than the Phantom 3 and may automatically throttle up but if it doesnât you need to know what to do.
If the Mini 2 simply falls level I do not know how you will tell if and when the motors restart, you are on your own there.
Assuming you get a successful restart and regain control I would switch the CSC response back to âEmergency Onlyâ or âBreakdownâ ASAP, it is ALL TOO EASY to trigger and motor stop in âAnytimeâ.
If you try this PLEASE post the flight log irrespective of the out come.
STUNNING! ITâS A SCOOP!! the Daily Fail strikes again! Tell me, just how many consumer class drones can get up to 5000 feet? This kind of scaremongering knee-jerk (with the emphasis on âjerkâ) tabloid tat is one of the main reasons why drone users have a bad rep. If the pilot had been around in the 1970âs this rag would have reported a UFO close call.
Interesting thing, human perception.
Back in religious days, âUFOsâ were âangelsâ or some-such. These days they are âaliensâ (or drones etc).
Brain perceives something in the sky which is unfamiliar and tries to rationalise it. The way it is rationalised will depend on the cultural context.

Vision scientist, Pascal Wallisch, wrote about the âGold and White, or Blue or Black, Dressâ phenomenon and in one paragraph he states:
- âThe brain cannot be accused of epistemic modesty. It is well-known that in situations like thisâwhere it faces profound uncertaintyâit confidently fills in the gaps in knowledge by making assumptions. Usually, its assumptions are based on what it has most frequently encountered in the past. For instance, if the sensory information is more uncertain, observers will estimate object speeds to be slower than they actually are, presumably because slow objects are much more common in the environment than fast ones. (Indeed, most objects in any given field of view donât move at all.) Color and lighting are no exception.â*
Why are there so few reports of UFOâs from astronomers? These folk spend an awful lot of time staring up at the sky one would think they would be a prime source of UFO material. Itâs because when they see a light in the sky they can refer to previous experience and knowledge and dismis it as either a man made or known natural phenomenon. Those without the same knowledge and experience will quickly assert the unknown to be supernatural, usually based on bad media and pop culture influences.
Another instance that sticks in my mind was about a tree in LA that was said to be weeping the tears of God. Those that believed the story would stand under the tree and claim they received various supernatural benefits. In actuality it was the height of the cicadas season and the reality was the worshippers were being pissed on by the insects.
