This is a very informative crash analysis of the Mini 3 Pro by Ian in London. This individual always posts very informative information related to DJI drones in general. He talks with facts, no speculations at all, must watch video.
Yep exactly... now he's on the right track. And he got a DJI goodwill, this shouldn't actually be a warranty case, the drone worked as designed & described.He posted an updated video.
Just for clarity, what lesson is going in your memory bank?I own a mini 3 and this is going in my memory bank. I live in Colorado and all these scenerios are in my play ground.
...I am trying to get into the mechanics of the unit and not just fly the drone. I am trying to absorb any information related to the internal components, functions, malfunctions causes, etc ...using my Mini 3 to get the experience flying in tight quarters.
Thanks for your input. This is another example that Murphy's law can happen to the best, another reason to stay humble and grateful!Here below you have 4 general lessons that should be made from Ian's YT posting...
1. The full downloadable user manual... read it, understand it, try all out in a open location & re-read it until the info there is second nature and totally clear & logical.
2. Understand what makes these crafts fly stable, hold position, & brake when sticks are released... & when they no longer can manage it.
3. Learn to pay attention to what's shown on screen & understand what everything means, what's good, what's bad & what is in between... flying & making stills/video isn't one or the other, it's always multi tasking.
4. Until all 3 above is full done deal... keep it near, low, & slow and in open environments without obstacles.
It's actually surprising that Ian with his drone experience fail in all 4...
And here one extra...
These thing's flies nearly by them selves... most of the time, even without knowledge... but suddenly it happens due to the pilot's ignorance.
I am not being awkward but I think the specific lesson to be taken from Ian's accident and others of a simillar nature is the following.The drifting aspect because according to the video the UAS drifted a considerate distance. I am trying to get into the mechanics of the unit and not just fly the drone. I am trying to absorb any information related to the internal components, functions, malfunctions causes, etc. Which intern, will make me a safest pilot, the places where I fly are quite like that particular scenario. I own a Mavic 3 and an Air 2s, but I have been using my Mini 3 to get the experience flying in tight quarters. I am a nature guy and love to fly and venture in our gorgeous Colorado Habitats.
Nope, GPS is the primary means for holding position whenever the control sticks are centred.Where VPS is functional it can, and possibly normally does, override GPS in terms of holding position.
[...] be wary when low (within VPS range) over flowing water especially if the water generates foam etc. or waves or contains debris.
If it is suspected that the drone is following something in the water then I'd be inclined to send the drone up, out of VPS range, if that is possible.
Sorry but we will have to agree to disagree on which has precedence.Nope, GPS is the primary means for holding position whenever the control sticks are centred.
The vision sensor of the VPS only becomes the active means for holding position when GPS coverage is insufficient ....... etc
You're claiming the VPS takes priority over GPS? That should be simple enough to test for yourself.Sorry but we will have to agree to disagree on which has precedence. {...]
It's actually not that one or the other takes over. Remember that GNSS itself is not a primary data source for the fusion calculation in any situation - that's always the inertial data from the IMU. The GNSS, compass, barometer and VPS data are then folded in with varying gains (weightings) depending on estimated error margins, via a Kalman-type algorithm.Sorry but we will have to agree to disagree on which has precedence.
I am going by my observations. For me positon holding, at a given location, was better is daylight, when VPS would have been working, than it was at night when VPS could not work.
Relying on VPS alone, indoors, my Mavic Minis and Mini 2 s are cm perfect in hovers in both the short and long term. I have actually left one of them hovering for 10 minutes whilst I was in another room and when I came back the drone was within single digit cm of where I had left it.
Out of doors, in daylight, with 18 - 23 satellites I would say that they hover within 1ft of their 'assigned' position. it is rarely windless where I have flown such flights so they do get buffeted a bit even on a 'calm' day. At night, reliant on only GPS, the oscilations were significantly larger, maybe greater than 2ft.
It is my recollection of threads discussing drift downstream there was no concern about satellite numbers.
I am saying that is the impression I get.You're claiming the VPS takes priority over GPS? That should be simple enough to test for yourself.
