My first crash was an interesting one. Help needed.

[Jussaguy]

I like you. Too bad I can't help you with logs.

In a different direction, why do you use DJI Go for waypoint missions? With your experience and knowledge, I see you using Autopilot.

I never used Go for wp missions, but I can only imagine that having to fly the mission first to log the points, and the bird stopping at each point during the mission has its limitations for your use.

Is this not it? What am I supposed to do. I am actually trying to meet a crunch right now and as soon as I do I will go look at PhantomHelp and see if there is some other info that I am not doing in about 20 mins. I thought I posted it but here it is again. These are 35 pages of what was happening. It was the last 46 seconds where I realized FOR SURE I was off course and it was too late and I just barely hit the tree as seen on the video. I believe the bird would have been fine if they would have let me get it out of the tree before it fell but they were promptly kicking me off their property until I was able to discuss it with them further the next morning but by then it looks like it fell from the tree. In fact they said it did. I don't know how much damage was done by the "tree landing"

Honestly, if someone crashed their drone on to my property and then trespassed on my property there is a fairly good chance they would never see the drone again. If they politely knocked on the door and said I crashed my drone into your tree I'd try to help them get it out.

Yeah, but what if you were walking in a valley and up a mountain and you were looking at an iPad to see where it was and before you knew it you were on someones property that you didn't even know you were on? The only way to get to the property was to ring a buzzer at a half mile driveway that I only knew about later.

I was just following the GPS and I was on the edge of their rather large area, I was not very close to the house until I got to the bird. The people that live there and myself realized we were on the property at the same exact moment. Thanks for the advice though.

I'm glad the people that lived there were nicer than yourself. In fact, the lady that owns the house owns a VFX company and we have worked together in the past without having even realized it until later. They were quite nice once we knew who we were. To state more accurately, I worked for the company that she owned on a couple of occasions.

Can never understand why people even have to post something like this. I mean, what are you trying to say here? I shouldn't fly my UAS? I wasn't trying to fly near their house but would fly over it if I wanted to. It went off course and I am trying to figure out why. I would not have flown on their property. If you watch the video, you can see that the proper way points, DO not go over their property. It only did when it went off course for a reason that is the purpose of this thread.

Also, I would not care if anyone flew over my property. It's also a gray area as to when and where the property in the air is property of the land. I was still like 130 feet during the collision.

Since the tree was on their property, regardless of height, even though it was super high, it is probably their property but thats not the point and I am annoyed at myself for even writing all this.

This is the tree your drone crashed in to: https://www.google.com/maps/@34.1294854,-118.4213849,126m/data=!3m1!1e3



Again, if it were my property and trespassed you would not get the drone back. You'd also be escorted off of my property at gun point more than lightly. I'm just saying not everyone is happy about people trespassing.

Okay, thank for the input. Appreciate it. I will try not to accidentally trespass in the future. lol :face palm:

EDIT: Look at your own pic. I walked up from the valley watching foot by foot before the battery died to get to the bird. That area leading up to the tree is a VERY steep mountain hill of which was extremely wet and I was doing my best to carry the remote and the iPad pro to find it. The second I got to the tree where the bird was when we realized I was on someone's property.

I would be VERY careful about using your said gun because if you had used it on me, and we went to court (or the state did because you killed me) the story of how I ended up there by accident might make you in a bit of trouble. I was on their property for all of a minute and removed myself promptly once I realized I was.

Fortunately, again, they were normal people.

How do you "accidently" do that? Is any of that area public land other than the road? :facepalm" LOL

 

[Jussaguy]

OMG, where is your reading comprehension and what is the purpose of this?

Yes, the valley right below the house is completely public and much much larger than it looks on that pic and that is the area that I entered from. I walked into the valley and up the mountain and ended up in their yard. That's all, nothing more. If you're picture went down more you would see empty valley.

Can we end this discussion now? I understand and appreciate your position on it.

@AlecW

Here is a better view of how I didn't realize I was walking on someone's property until I did.

I was where the cars are. If you watch the video (you can't really tell from the pictures), the valley is 100s of feet deep. Now I don't even know if this was my actual path. I just sort of guessed from memory TBH, but I wouldn't lie as there is no reason to. I am not here trying to figure out property laws, I am here to try and figure out why my P4 went off course but to satisfy your desire to know why I ended up on someone's property without permission, I offer this.

I also offer this advice, I would be a little more judicious about what you would do with someone else's property that ends up on your land.

I called the police to ask them what I should do when they (the property owners) at first said I had to wait until Tuesday until their guests left and they said they would send out a car to ask the people that lived there if I could get my property. Even though my property ACCIDENTALLY ended up on their's, there are two forces of property law at work. Because I didn't want to cause anything with people that I might work with (and actually did), and because I wanted to eventually get my bird in good shape (as I thought it was in the tree and was), I didn't want to tick them off by having cops knock on their door knowing the whole issue was the guests. Otherwise, they had no problems with letting me get it. They were quite nice.

My brother who is a securities lawyer for one of the largest hedge funds in the world knows a lot of people and he called for me a world renowned Stanford law professor who specializes in property law and he said that I have as much right to my property as they do to theirs. So if I could prove that you took and did not return my property, you would be forced by law to return it or provide another one and if I could prove you destroyed it, you would be fully liable for it regardless of how it got there. The property invasion (trespassing) would be a whole other case in which I could easily prove (to a reasonable person to the preponderance of the evidence which is 50% for civil property part, the crime would be trespassing) which is the jurisdictional standard that I accidentally trespassed and got off the land as soon as I was asked. And if you happened to shoot me for trespassing on your land in broad daylight at about 11am on the VERY edge of your land, YOU would have to prove "beyond a reasonable doubt, again 99.9%) that you were threatened and I purposefully invaded your land to cause harm. So if you shot and killed me you would probably at a very minimum be in jail for manslaughter. (There were about 6 people there and we all saw each other at the same time and were very cordial and also create 5 eye witnesses that I don't think would all want to purger themselves but you never know I suppose.) Of course there is always the possibility that all the other witnesses could say I had a knife that I ditched and was threatening them. It's totally possible that 12 reasonable believe would believe that I was flying a drone that crashed into a tree and have the GPS markers to note the crash, and my walk over there. It could have been a rouse to make it seem like I was just trying to get to their property to mastermind a home invasion by crashing my P4 into their tree in broad daylight. I am not some anti-gun person by the way, so you can save that. It's just insane to me that I am just trying to figure out what happened and you have to post something as unrelated as this. Also, I have done my best to help people around here multiple times, including posting multiple reviews, tutorials and whatever. I just don't understand people that go out of their way to be un-nice.

So here is a better view of the actual how I ended up there. Of course I would rather have knocked first. I was just looking for my P4 and didn't even know for sure it was not retrievable in a bush somewhere at that point.

*By the way, I did walk around that house that you see there on purpose. I could see that my "feet away" was getting closer but slower as I walked around that house but I did so to STAY OFF THEIR property so that also sort of kills your theory that I ended up on their property. They also asked me how I ended up there and I told them it is perfectly accessible from the valley and they thanked me because now they will put up a fence. Both they and I were surprised I was able to climb up that VERY steep area from the valley to their property.

Now, can anyone tell me what I need to provide from PhantomHelp other than what I already have? Please.

You done it right.. it converts logs to readable data. I seen on the last page, RTH was initiated. Did you initiate or did it lose signal and initiate itself? Go won't finish a mission like litchi if signal is lost. I'll take a look at your healthy drone log in a bit to see other clues.

Oh, and no, I never lost signal. I think I didn't initiate RTH until I was already in the tree.

The spot where it is X on the HD logs is where it seems to have hit an then all the motor and gimbal obstruction warnings came in. How can I upload the path from the Go App? That would I think help.

When it didn't go through those two trees, I knew something was wrong but didn't know what. I should have switched to ATTI at that moment but just didn't and wasn't 100% it was off at that point. I just thought maybe there was a wind gust or something stupid like that and then by the time I realized I was heading for a tree, I had seconds and could not recover in time.

Although it was one flight, it was really 3 missions. One I recorded the WPs, the second I just was recording the waypoints, and then the third (Starting at R on HD) there was no problem until it crashed with the exception of the "entering altitude limit mode" which I don't understand. I am number 12 in the cue with DJI now. I have resorted to seeing what they say.

Thanks again.

You uploaded a picture of your healthydrone log.. we need the actual link to that flight log. Open that flight in healthydrones, and share the link.

This?

HealthyDrones.com - Innovative flight data analysis that matters

Please remember that R is where the "mission" that started the ill fated mission began.

In other words, where it says "switched to waypoint mission" before the RTH, the atti mode or sport mode, was just me getting it ready for the third round. At I believe R, that was where I was going back to waypoint mode but it wasn't following the WPs. It MUST have something to do with that "altitude limit mode" warning but I thought that was just because of the valley or something but considering I fly over the valley often, and have in WP mode on several occasions, I should have paid more attention.

I never used Go for wp missions, but I can only imagine that having to fly the mission first to log the points, and the bird stopping at each point during the mission has its limitations for your use.

It's certainly not my WP mission of choice but it works in a hurry which I was in. I prefer as you noted AP, and Litchi for WP missions but this was supposed to be a quick in and out and I don't mind setting the waypoints with a flight if its a signal flight.

So because I can't seem to figure out what people want me to do from PhantomHelp, I am just going to upload the three files that they sent me. I already send the logs via PDF which is 30 pages because as I said, this was essentially three missions, flown 3 times. As you can see, it flew the WPs just fine twice but the third resulted in the crash (barely).

It won't let me send the KML and CSV files, whatever they are.

 

[JohnnyB]

I'm sure the more experienced will chime in, but one thing is see is you switched to atti right before starting the mission. What I do know, you'll have drift in atti, no brakes, you start it in a direction and it will keep going until you stop it, so to speak. BUT, what I don't know is..., (because I've never tried it) is how a Go mission will carry out in atti. Still looking.....

Appreciate the help but you're looking at it wrong.

I am an experienced flier. First, you can't fly a WP in ATTI. The third mission for all intense and purposes began at R where it says "Starting Waypoint Mission" and entered NaviGo. Until the crash, and right before it, the only notice I got was right before the crash where it said "altitude limit mode".

Look from R. That was the third round and it says "Starting waypoint mission". No warning from there. Sometimes I switch to sport mode or atti mode to get it back to the area that is near the first WP mission. Again, 3 WP missions here, not one, for purposes of ease, I've just posted the part where it went from WP mode to the crash.

Thanks for looking into it!

@JohnnyB

EDIT: For reference, look at this. I just copy and pasted but it should show you what I mean. I was in atti and/or sport to return to the WP first point, and then switched to and began the WP mission which it flew correctly two times on this flight before it.

So as you can see, I was most certainly in GPS WP mode when it crashed. I would love to see what I was doing on the sticks at that time but don't know how. I was aware at that moment because it didn't go through the two trees that it did the last two times the something was up. It HAD to be the Altitude Limit Mode or just maybe interference or just a freak out on the board? I have no idea which is why I am so perplexed. If I knew why, I wouldn't post this. So frustrating now knowing why it acted this way.

P 07m 09s 128.6 ft 41 ft Mode Mode changed to GPS_Atti
Q 07m 36s 128.3 ft 41 ft Tip Waypoint Mission Started__Return-to-Home Altitude:492FT
R 07m 36s 128.3 ft 41 ft Mode Mode changed to Waypoint
S 07m 50s 75.8 ft 12 ft Tip Arrived at Start Point. Starting Waypoint Mission
T 09m 39s 132.5 ft 926 ft Warning Warning:Altitude Limited Mode Entered
U 09m 41s 136.2 ft 943 ft Warning Warning:Altitude Limited Mode Entered
V 09m 43s 139.1 ft 958 ft Warning Warning:Altitude Limited Mode Entered
W 10m 00s 169.6 ft 1,078 ft Warning Warning:Altitude Limited Mode Entered
X 10m 46s 134.2 ft 781 ft Warning Warning:Altitude Limited Mode Entered
Y 10m 49s 130.6 ft 761 ft Warning Warning:Motor Obstructed

It began the WP mission at 7m 36s

and first warning was "altitude limit mode entered" which frankly didn't scare me. Thought it was just some safety mode that I was unaware of.

A couple minutes later and less than a minute from the crash I got the first warning. The crash happened at about X and Y. I did' realize it was heading for that tree until W and that 46 seconds wasn't enough time to correct what was wrong although I was calm the whole time. I almost, as evidenced by the video escaped the tree but missed it by a nano inch.

Thanks again

OMG, where is your reading comprehension and what is the purpose of this?

Wall of text and I never said I'd shoot anyone but I would walk out my back door armed if someone was milling about on my property uninvited and looking for something. It's up to you what you do in life but like I said if someone came to my door and politely asked to retrieve their drone I'd help them.

 

[AlecW]

I wonder if the Altitude Limited Mode Entered warning had anything to do with the class B airspace warning? Maybe it was trying to keep it lower. Just an idea, I've never flow in class b airspace or seen either warning.

Well that is EXACTLY what happened but they didn't really help me until the next morning because of their guests which is unfortunate for me because I believe the damage wasn't done until it fell out of the tree. That said, I didn't even intentionally walk on their land.

Also, your "I would keep the drone and never return it" is a lot different than what you are saying here but maybe I misread your comment. Conversation concluded. I completely understand not wanting people on your property without permission or expected as I think anyone would understand.

 

[Jussaguy]

That class B warning is because of Burbank Airport which is several miles away which I get whenever I fly there and I am always cautious so unless it's something new, no idea. Also, as always, I call the tower at Burbank before I fly and had 2 hours of under 400 feet from 10am-12pm for a quadcopter at that location. Either way, I don't know what it was doing.

Your help is greatly appreciated though.
