You have to have a good sense of humor and look at the bright side, now I get to build another one. Ok, easier said than done. These are my crashes I have caught on video.

Great! Thanks for sharing.

No guts, no glory.

I especially like the 200 foot elevation one. You crashed back on your own deck! No POW status for you:p

To quote T. Roosevelt.

"It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat. "
 
I am curious about crash #3 as I had the same experience with two crashes myself - here is the video from one of them:

Both, the modified Elev-8 and Tarot 650 Sport had ESCs mounted under the motors with power/ground leads running through the booms to the pwd harness in the chassis. I learned from another forum that such an arrangement can cause high voltage spikes due to the switching action of the ESCs and to combat them you need to install some capacitors, I think 220 micro farads for every 4" of wire length. Anyway, I've built a new machine, another Tarot 650 Iron Man, and installed the ESCs underneath the chassis.
 
The ultimate Tree Crash. I have a great deal of experience with that having done so each time I take off. My quad should be renamed the Robi Chain Saw.

That crash on my deck remains a mystery. I had flown that quadcopter, my beloved first homemade quadcopter probably 100 times. It was always my go-to. I just got a Tarot T810 that has capacitors, but to tell you the truth, I am a little gun-shy right now. Had so many crashes all within a short time I have lost my nerve. I have enough Parts laying around to make another homemade quad with the exception of the carbon fiber arms. I will be ordering them soon and we'll start another build.

Lol, I always do my hover tests above a nice soft pepper tree. The one that I crashed into in the video was a nice soft pine tree :) My deck was not so forgiving.

I know what you mean about being gun-shy. After my two crashes I decided to give up, but like you, I had a bunch of parts laying around and I missed not having a flying video platform, so I decided to build a new one - the Tarot Iron Man. It was scary taking off yesterday, but it did fly. But there is a throttle surge problem I''m researching - indications are it has something to do with the Arducopter firmware.

While waiting for new ESCs to arrive for the Tarot, I inventoried spare parts and other parts I had salvaged from an Elev-8 crash and determined that I have almost enough to build another Elev-8, including the stock motors that were still in their packaging. So I've started to resurrect an Elev-8 (v2) - will be stock except for the flight controller - will use APM 2.6 and external gps/compass - I like being able to fly it autonomously as well as have RTL. This will be a test aircraft...

Good luck and keep us posted on your build!
 
We need the parachute technology of model rockets included in quadcopters. A Proximity Switch that detects the ESC stopping at a certain minimum altitude would deploy the parachute. Better than a hard crash in any case.
 
This one took a month off of my life back in the day. Sometimes it is the hardware....

Long story short, it was my escs. It flew great until I would make a quick turn.
