Yesterday,  I planned and executed a perfect waypoint flight using the Litchi app.  Naturally,  having one successful attempt under my belt,  I now considered myself an expert.  Since I actually had a task I needed to get done,  namely mapping out the locations of various vehicles and other junk on the property,  I decided to do it with my P3Advanced using Litchi and the waypoints.  I carefully planned the flight track,  using Google Earth to verify ground height so I could program the desired height above ground level for each waypoint.  I wanted the entire flight at about 10 feet agl for the best perspective,  but I added a couple of extra feet for safety.  Did not want to autonomously fly into a rock pile,  car or bush.   There was only one point where I came near any power lines,  and I carefully adjusted those 2 waypoints to go under the power lines by a good 8 feet.  And I did , in fact,  clear the power lines by about 8 feet.  What I did not clear was the telephone line.  It hangs just about 8 feet below the power line on the same pole.  And of course,  the P3 and the telephone line did not get along well together.    To make a long,  humiliating emotionally painful story short,  it busted 3 props and snapped the camera gimbal off right at the weak point where it attaches to the swivel in the base.   The camera lens got scratched quite a bit,  but the ribbon cable, oddly enough,  looks okay.  Some bits of sand and rock in the motors,  I am pretty sure that will come out with some canned air pressure. No cracks in the body that I can see.

Now,  I also have a Standard.  I am wondering if the gimbal from the Standard can be used on the Advanced.  I know the camera is different,  but the gimbal?  Anyone know the answer to this?  Also,  does anyone know what the camera and gimbal assembly cost?

I am so mad at myself,  I may strap myself into an uncomfortable chair and prop my eyes open with toothpicks and force myself to watch endless reruns of the republican debate.

I am sorry to hear what happened. However I am torn between sadness and outright mirth at this:

"I am so mad at myself,  I may strap myself into an uncomfortable chair and prop my eyes open with toothpicks and force myself to watch endless reruns of the republican debate."

Please, there is no need for self-mutilation.

Unfortunately, to add to your pain, the gimbal is not cheap: http://store.dji.com/product/phantom-3-advanced-hd-camera

One thing that has nagged at me for some time is the issue of the gimbal mount breaking off. I figure the main gimbal electronics and camera may survive quite well, so there is a real need for DJI to provide the arm section as a spare. They might do so, but I cannot find it.

Sorry about the incident.  I do myself and I have a good friend who does even more than me, very carefully pre-plan flights.  Unfortunately not everything is on the maps we use or accurate enough to rely on in some cases.  I try, whenever possible, to visually see as much of the flight route as possible just for this reason.  Can't plan for something you didn't see.  But when I am not sure for whatever reason, it is either altitude is my friend and I don't get the shot or I just don't try that point and move on to the next.

Sorry I can't specifically answer your question.  I don't know enough about the standard.  Oh and scrap the toothpicks idea.  Not worth it and you will just end up with these ugly dents in your face that you will have to explain for the next three weeks until they disappear.

i don't think so. I know the Professional version has the SD card built into the top of the Gimbal and I assume that the Advanced is the same way? If so, the standard has the SD card slot built into the actual camera so the Gimbals are not compatible.

Ordered a new camera and gimbal assembly.  An expensive mistake.  $359.00 usd for the camera/gimbal, new OEM Dji parts.  It occurs to me,  those parts cost 359.  The remote controller is supposedly 650.00.  Those two parts cost as much as the entire advanced.  So I guess the best thing to do is break the P3 only.  Because it must be free.  Just don't injure the camera,  gimbal or remote and you will be fine.  But wait,  the battery is $150.00 and 20 bucks for a set of props.  This is like dealing in auto parts.  A car is worth 10 times as much in parts as fully assembled.   Or maybe this is like buying a printer.  60 bucks out of the box ready to use,  but wait till you buy new ink cartridges.  It's the consumables that they hit you for.  So,  Camera,  gimbal, and r/c should be considered consumables??  I dunno.  I'm rambling and still in shock.  I'll be fine once the new parts are installed and I am flying again.  Until then,  I will have to be happy with the ( ho-hum ) Standard.

Wow...that looked very close to lots of stuff.  Could you see the drone while it was flying or just FPV?  I imagine even if you were watching it you'd struggle to see it was going to crash.  Distances become difficult to judge very quickly, especially things like power lines.

Knee,

Really saddened to see your note. Very happy to see your honesty, you're a better man than me! Now, you can consider yourself an "expert"! An expert learns through experience, seems to me you've got some good (bad) experience and you'll get much more before you're in the air again.

I made a similar error in judgement a bit ago myself and I'm a big-time pre-planner. I spent a few days putting together several multi-mile waypoint runs. I went over and over them to insure that I had everything covered. I picked a perfect time to go to the site to make the runs a few weeks later. I ran all four runs flawlessly! They were absolutely perfect! I was elated!

My Wife (of 30 years) was with me and suggested that I try one more run at a much lower altitude. I actually said to her "No, I got what I wanted and it was perfect!", she in turn explained what she had in mind and how great it would be. I thought about it, looked at what she was descibing and thought "Wow, that would be a cool shot!". I got really nervous and the adrenaline started to pump (should have been the hint), I could just make one more quick run since I was already there. We went back to my truck where, for the very first (and last) time, I put together a quick run. I'm sure you've already figured out the rest of the story. The run didn't go as hastily planned, I missed a low hanging tree, 30' above concrete. Bird was destroyed. I now own a P3Pro Main Board with four damaged motors hanging off of it.

I am a perfectionist, I preplan and replan, over and over again. Excitement for "the shot" and not listening to my gut, did me in. Entirely my fault and for a veteran "expert" like me, a very damaged, embarrassed and bruised ego. For an hour or two, I almost through in the towel. 48 hours later, and with encouragement from my Wife and Friend #3 (who already posted here about planning) had a brand new P3Pro sitting in front of me.

I'm now over it and back in the air with the always steady P2V+, my Solo and my newer, firmware jacked, P3Pro, just waiting for breaks in this horrible weather. I have gone back to planning and replanning and have learned all too well that making complex, gut runs on the fly doesn't work. I won't do that again!

Knee, keep your head up, learn what you can from your rebuild and jump back in the air. There are thousands of stories similar to ours out there but they aren't shared very often. You're a good dude and a great contributor, keep on keeping on!

Thanks to all for the kind words and encouragement.  After (some of ) a nights sleep and time to reflect,  I realize it could have been worse.  As it was,  it ended up costing the price of a new camera and gimbal and 4 props.  No humans were harmed in the making of this disaster.  Except for pride and wallet, of course.
The part that bothers me most is that I had done the exact flight the day before,  albeit at 30 meters altitude.  And it was flawless.  As I mentioned in the original post,  the purpose of the flight was to map out and itemize all the stuff on the property.  This is quite a big job,  because the property is 150 acres,  and much of it has stuff on it,  much more than the short video shows.  Yes,  it is kind of a good setting for a horror movie.  Over 35 cars and trucks.  Well over 200 motorcycles.  Essentially,  50 years worth of collecting things by a packrat who never threw anything away.  This video started at the beginning of the " collection ".  The end point was near the home point.  All preprogrammed altitudes were referenced from the home point.  I was on the roof of the house,  wearing FPV goggles.  So, I had a front row seat.  The previous flight I had expected to be the only flight as it covered the entire area right where I wanted it to be.  But my attorney,  after reviewing the video,  suggested it might be better at lower altitude,  specifically at about head height.  This to make identification and evaluation much easier.  Being flush with success from the first flight,  and having never been known for an excess of prudence,  I agreed.  After all,  what could go wrong?  Did I mention,  abject stupidity is my prevailing trait,  it seems.
In any event,  I did get the video,  shot more or less how the lawyer advised.  I did it by carrying my Sony HD videocam  around in my hand,  using my legs for locomotion.  What would have been a flight of 2 1/2 minutes became a strenuous hike of over 20 minutes with my arm extended above my head the whole way,  like one of those mystics in India who keep their arm above their head their entire life to show devotion to their gods.  I must have looked liked a madman,  trying to position myself to keep my shadow out of the video; not easy to do in the late afternoon California sunlight.  I spent a lot of time walking backwards,  spinning around and playing hide and seek with my shadow.  Unfortunately,  my dog felt no such obligation,  so the entire video has her making cameo appearances.  This video is going to be seen in a public courtroom setting.  And I will be there for everyone to think, " That dummy!  He should have got himself one of those flying cameras to do this with.  Nice looking dog, though".
Oh well,  I guess it was a nice day for a walk.

I thought so too.  I was wearing the goggles and saw it as it happened and I really thought it would clear.  But the P3 did a ( programmed ) slight climb to clear a rock pile and that is what screwed the pooch.
After reviewing the first video again,  I realized I should have told the lawyer it was fine.  It conveyed the problem very well.  But no,  alas,  I flew the fatal mission and the rest is history. The purpose of the video is for a court case I am involved in.  I needed to be able to show how much stuff was on a piece of property.  The first run,  shot at 30 meters,  is here:

You are probably right.  There is literally over 50 years of stuff here.  The fellow who died never ever threw anything away.  You should see inside the house.

Meanwhile,  I flew the Advanced today without the camera and everything seems to be ok.  Other than the destroyed camera.  It flew straight and true,  no wobbles or weird noises.  I am very relieved about that.  The camera and gimbal assembly will be here Monday and all will be good as new.  
There I go being optimistic again.

Hi Cetaman,

Yes,  that is exactly what it is.  And it is a beautiful place.  Very dramatic,  near the edge of a cliff on a very deep canyon.  At the right altitude to normally be bearable temperature most of the year,  especially compared to down the hill where summertime temps often exceed 120 f.
