I have been involved in the maintenance and design of Aircraft aiframes and Aero engines for all of my working career.  One tool that is in constant use is called Health and Usage Monitoring system HUMs.  This is where each aircraft and engine has each of it's flights, duration and fatigue recorded over it's entire life.  These figures are used to continuously compare the predicted life of the airframe and components with the actual life recorded in the real life usage, so that the two can be correlated and confidence in the systems for life monitoring can be improved and refined.  

DJI has provided us with the starting point for a similar study on our P3s,  i.e. Flights, Total flight duration, and distance flown all all recorded on the GO! App.
To this we could collectively add our own experiences of failures.  This list could contain the following:  
Body cracks ( lower body to upper).
Body Cracks ( lower body to motors).
Landing gear cracks.
Props broken or cracked, or replaced.
Failure of motors.
Failure of ESC.
Failure of Camera.
Failure of Gimbal.
Failure of SD card.
Failure of contoller.

Battery life.

Also conditions of flight could be recorded such as coastal, mountainous, desert, mixed.
Minor crashes.
And ultimately, and sadly, fatal crashes.

If all successful pilots with over 100 flights, this number will indicate that you have no tree magnetism, nor suffer from the did not RTFM affliction, would be willing to send me thier data to include the above, and then update their usage every 25 flights, we could collectively and over time build up a database of when, if ever, we could expect any failures, or if there is no pattern of say a motor burning out after 450 flights or 300 miles of flight, that would give us a collective warm feeling about the design and reliability of our craft.  If on the other hand most people who attain 600 flights have problems with ESC or battery down to 40% max, then this could be a good indication to the whole community of what to expect if you are approaching these milestones.

I can start the ball rolling with my own figures:
Flights 112
Time 14 hr 42 min
Distance 84 Km.

Faults.
Single crack to lower body to upper body screw hole after 74 flights.

If anyone thinks of any more failure modes or a different way we can record this then please comment.
Perhaps P3 Serial numbers, and date of purchase could also support a trend, if one exists.
I have posted a template for any users with 100+ flights to use if they are interested in this excersise.

Thanks for you time.

Arrived 4/2015

3 batteries used (50 flights on original and 25 each on the newer ones. All health at 100% still but I can note that 1 of the new batteries has minor voltage fluctuations and the other 2 don't)
9 hours total flight time
70 miles total distance
100 flights

No cracks. No damages that I can find. I have used several different sets of propellers with no problem. My VPS didn't like FW 1.2.6. All was corrected with 1.3.2. Overall I am very happy with this model and look forward to some of the new feature soon to be released.

285 Flights
55 hours 50mins.
360Miles
4 batteries, all at 100% life
mountainous area, flat lands, beach.
90 degree farenheit, %hell humidity, strongest wind 20mph
present P3P = no shell cracks, no screw well cracks, 100% solid.
1 drop from 30' due to inadvertently doing a CSC. busted gimbal, landing gear, shell screw cracks.
painted this one black, repaired and flies rock solid. now passed on to my 11 year old kid.
2nd p3= 1 crash at 20mph, low flying, ground came up and i didnt. no damage, but replaced props. 2nd crash at 3' into a tree @ less than 5mph. no damage, but replaced props.

routine daily checks:
motors
all screws
every inch of shell is checked
battery housing and clips are checked
props under a microscope and the threads
motor threads
all visible ribbon cables and wires
battery life, cell variations

chks b4 flights:
chk compass mod values, i do not calibrate compass. ive calibrated it once after fw update and have travelled 1000 miles to the beach and flew without compass calibration but i religiously double check p3 compass bearing using a manual compass.
battery and cells
10+ satellites b4 take off
home point b4 take off
wind speed and direction
tallest object in flight path
cell and radio towers around flight paths
electrical, telephone lines that are difficult to see
where to drop it if in an emergency
hover at 30' for  a few minutes while testing all stick movements at 100%

i am sure ive forgotten to write down a few more
it sounds like a lot preflight but it doesnt take but it takes less than 5 minutes.

Yeah most people do not do accounting and statistics like the few of us do, it's personal preference and the culprit is always an ESC as second place then first place is human error in crashes, and the ESC fused to the main board, so it's a loosing battle.

well give it time, sometimes it takes a while for the thread to become alive.
but i for one think  ...

It would be a terrific idea is this information was collected automatically (gathered and sent to the cloud). Otherwise there's no way you can alert every owner as to how valuable this information could be. Consequently, thousands of owners will/would never be aware of the data and how it could be used to identify problems, maintenance, etc.

Personally, I think data collection works far better if, instead of paying $1,000 for your gadget, you paid $30,000 - I'll be there'd be a higher participation rate!

No firmware issues that were noticeable (and I have run through them all)
Only tumbled her through the grass once trying to be crafty, only grass stains as a result.
3 batteries, all still in tip-top shape
she's been flown in Sweden & Ukraine, so far. (very varied environments in both- an amazing thunderstorm before the rain started, mountains, over water, heat, humidity. so on, so forth...)

hope the info is helpful to someone.

amstaff - you must have THE distance records of all time. If my calcs are correct, you are averaging 881+- kilometers per flight!!!

I'm thinking that must be the distance in meters!!?

I like this thread!  I have been looking at the phantom 3 Pro since it came out but have held off until the bugs get worked out.  It seems like DJI used its customers as beta testers!  It's good to see people who are really getting good service from their Phantoms.  Now with the new features added, it looks like the time is right.  Thanks to all who have posted, you are confidance builders.

I'm only at 36 flights, 45.6 km, 6 hr 35 mn, but I like the idea of being part of such a data base. So far no damage, cracks, ect. Original props, never did anything unexpected, always land on the same 2 sq ft section of my deck.

Hi Chaps.
I now have data for 10 users, so thanks to the first adopters.  If you have managed to get this far congratulations.
The PDF shows the fleet leaders, average time per flight, average distance per flight.  Which is the only thing I can extract from the data that I have.
The most important thing I can see is that there are no mechanical or electrical problems so far, apart from the 2 shell cracks reported.
Fingers crossed that it stays this way.  As the flight numbers rise, we may get a trend or hopefully have a real nice warm feeling that the P3 is utterly reliable.From the normal forum posts we read about lots of crashes and firmware issues, but if you can avoid these, then 200+ flights are achiveable.

Please see the following Spreadsheet in PDF format for the data so far.
If you notice that data is missing from your row, will you please let me have the figures, and I will enter them.  Also when you reach the next milestone, i.e.125, 150, 175, 200 etc will you please advise me with the new flights/hours/dist data, and of course if you have any failures before these milestones let me know too.
If anyone else has achieved the magic 100 flight milestone and wants to share share thier data, please reply to this thread.  The more data we collect, the more accurate will be the predictions and growth in confidence in our P3s.  

Please see a couple of posts down for a blank from which will allow you to copy and paste to your post to help with the data collection, thanks to Rocket for this idea.

Thanks.

Hi Ray,
I have put the result of the first 10 replies to my post on this thread.  In .pdf format.
From the stats that you supplied I can't determine how many hours/miles etc are applicable to your main P3P and how many are applicable to your BlackBird.  Can you please let me know, And if you see missing data from your row can you please let me know the data.
I'm (well the whole group really) is interested in the data per P3 model, not necessarily your personal totals.  Thanks.

Great thread but could you perhaps have a post that we can just copy and paste with a standardized method it would also help you collate the info much quicker.What do you think...something like this>

That way we could just copy and paste in a  new msg easily and fill the info out.

I would suggest creating a simple form on a web page that lists each of the metrics you are trying to gather.   If not, your responses will not be uniform, IMHO.

If you want to do this and need help with it please let me know.  I use the free website builder weebly.com, the results can be viewed and downloaded in excel format.

2 original Batteries and one is still at 100% and the other is at 99%  both batteries still maintain constant/consistent voltage between cells.
1 new Battery  

Faults: No problems found to date (no cracks etc found yet).
I had one instance where it seemed like the GPS was not functioning correctly as it was flying opposite of where I was heading when it took off and I switched to atti mode to save it and brought it right back to me.  Not sure what that was but it has never happened again.

Hi capbat.
Thanks for your figures.  Can you please split the figures between each P3 that you own, then I can add your data.
I am more interested in the reliability of the machines rather that the skill of the pilot.  Although without the skill of the pilot there is no need for reliability of the craft.
Thanks.

To all who have responded here is the latest data that I have.
Good news is that of the 10 people who have responded there have been no reliability issues with the machines or electronics.  Just 2 cracked bodies.
If you have recorded more flights (in multiples of 25 flights) since you reported last, can you please update me so I can keep this databoth up to date and relevant.
Thanks all.
