Alright, this time I'll try to whine and complain a little less, but I think this is it.  After replacing gimbal after gimbal, broken arm after broken arm (are they always the blue ones that break?), watching my Iris drop dead from the sky time after time, I'm just ready to get out of this abusive expensive relationship.

I will give it just 1 more chance though.... and it hinges on how 3DR support will reply to my email I sent today.  Will they blame the pilot, again?  Or will they say "hey, you know what, you just might have a bad piece of hardware"

I took my Iris out to the park, wanting to practice some Follow Me paths while riding my bike.  Well, I didn't even get to hop on my bike before the Iris crashed twice, both times killing power in the air.

The first crash was luckily only 3 feet off the ground, so it landed on all 4 legs.  I flew it again, hovering around 4 - 5 feet for a minute or so just to see if it would kill again, nope, I landed it.

Maybe I'm arrogant, but this time I tried launching with the Tower app.  Launched fine, and as it climbs to about 20 feet I realize if it falls from that height, it might do some damage, so I pressed "Land" on my phone, and the Land button must be 3DR for "kill power and dive" because that's what happened.  

I wasn't so lucky this time, it took a nose dive breaking an arm and the gimbal.  Fortunately THIS time my GoPro was not harmed.

If anybody wants to waste some time trying to investigate a problem I expect 3DR Support will blame on pilot error, here are my logs from today.  But please, if you do find out what happened (other than it looks like you lost power here...), I would appreciate some feedback.  It would be interesting to see if 3DR support has a different answer too.

Here is also the entire video, uncut from today, for your laughter.

Like I said, 3DR has 1 last chance to impress me.  I've just received a bonus check from work for a couple thousand dollars, and I'm buying a new drone.  3DR Solo?  DJI Phantom 4?  Let's see how this support call turns out.  Last time they offered me a 15% discount on an overpriced Tarot gimbal.  No help with my crushed GoPro.  Not even a constellation prize set of propellers.

Great picture, any idea where it is taken?

@Sgt Ric,

let me in to buy all the trash by my lab for students.

email me back

Ha ha, ok maybe I can explain it this way.

Flying into a tree:

Operator error.

Flying after the low voltage warning and crash or lost:

Operator error.

Flying backwards and hitting a building or object:

Operator error.

Flying inside restricted air space:

Operator error.

Sudden power loss from a faulty ESC board:

Mechanical error.

I'll gladly take responsibility for any Operator Error.  Stop trying to classify a sudden power loss on the pilot.

Hi Darius, I apologize for being unfamiliar with telemetry logs, are they not included in my Dropbox link here?

I just want to fly and film aerial footage.  I do not want to tinker, customize, edit, or optimize any part of the drone.  I want one that comes out of the box and fulfills 1 purpose.  So it sounds like DJI Phantom 4 is the one for me.  

I just regret believing the advertisements for the Iris up until Feb 2nd 2015, as it was selling a drone that was great for beginners, yet was easy to film professional grade video.

Then after I got the gimbal, GoPro, and video transmitter antenna on there, and I thought back to the phrase from the promo video "When we see the Iris, we think 'Aerodynamic'".  I heard that losing horn music from the Price Is Right playing in my head as I looked at the monstrosity that now existed as my Iris, and to think it looked "aerodynamic" gave me a shiver.

Sorry to disagree, crash due to not doing a pre-flight check is  an operator error. 

The main point is, you ignored the power issue (from your previous crash) and popped up your iris at full throttle. That is a textbook operator error. improper pre-flight check.

Thank you Sigitas, but I will respectfully decline.  It's too much effort just to jump through the hoops and at the end of the road they just try to sell me a Solo.

They are currently making me contact the Amazon seller to find out their order from 3DR, in hopes I'll just give up.  Seriously, what is that order number going to tell them that my serial number won't?  

Here's what will happen, I go back and forth with the seller, finally get their order from 3DR, I send the info to 3DR, they say "ummm, that doesn't really tell us anything, we won't be able to help you".  Then I say, why did you make me track down this info?  Then they say please buy the Solo, our call center is experiencing an unusually high volume of calls at the moment, your call is very important to us.

If you are not satisfied with our product, please give us more money and buy our latest product, because our customer service quality suddenly changes with a different product.


telemetry log files come with .tlog extension in case of Mission Planner, Tower.

Get it from Tower.

Respectfully, can you please tell me what you would have done after the first power failure?  What would you have done, what would you have looked at?  You've got the logs there, the video footage to show what happened.

Have I not provided the same data logs that I would have access to, so I could have followed your advise?

There is not a single response here that has shown me what I should have done after the first power failure.  

What I DID do was launch it again, had it hover for a few minutes at a safe height, and nothing went wrong.  I continued to learn and experiment.  

Instead of continuing to blame me for launching again, will you please instead offer a solution?  The data is there.  I await your suggestion.


In my previous reply, you should use mission plsnner app to download the log. Your log showed a significant voltage drop which is a clear indicator of battery issue. Even you have no access to MP, a prudent operator would abandon the mission and check the air wothiness of the power system before fly again, the least you should have done is checking your battery, and/or change the battery. Instead of abandoning the flight, you push the throttle  (by auto launch, another pilot error). It is like sending a football player who just had a concussion to  head check with the oposing player.

You were lucky that you have not caused any damage to other. Otherwise, a good lawyer can take you to a cleaner for negligent.

Just write off your lost and go buy a P4, I doubt any one in this forum can give you support for a claim.

PS. I'm in the "blame" business, Although I know that is not what you wanted to hear. that is my analusis of your crash from your log and video.

A test of P4 shows the weakness of P4 OA

Oh there it is, I'm lucky now. How was I lucky that I didn't cause any harm to others? I went specifically to this park in off season, because there are minimal bystanders. Or maybe since I'm such a terrible pilot, it was all luck and I could have just as easily mowed down dozens of kids with the propeller blades of destiny.

You know what? You're lucky you decided not to run that red traffic light today, you could have been in huge trouble for manslaughter if you would have ran it.

Any non murderous driver can see that driving drunk is bad, so please don't do it.
