Went out today for my final chance to get a picture of a tree, wee bit windy but no dramas.
Drove 40 minutes to my intended subject and got set up, then realised both my memory cards will still sitting at home…DOH!!! No dramas, the Air2 has enough internal storage for my purposes.
Sent Bob up (yes that’s her name) waited on satellites and made my way over to the tree. Bob was struggling a little in the wind so I flicked into sport mode, completely forgetting that it had been assigned to ATTI mode at The Big Meet. Bob decided to turn upside down and crash land in a muddy puddle. Four knackered props, covered in mud, sticky gimble, and possibly a sensor knackered. AirData says Detected Side Shock/Possible Collision. It was neither, I was only a few feet away.
I gave it a clean, changed the props and sent her back up, no not in ATTI mode this time. Got my picture and left. I’ll wait until the wind calms back down and get her up to check everything out, think I might just have got away with it.
A mucky bottom
Destroyed props. Top two are pretty obvios. Bottom two are tight to fold/unfold. In the bin they go.
And no, I didn’t chip them by folding/unfolding the arms!
Why did you change sports mode to atti it’s best to set cine to atti as that’s the crap mode
Because I use cine mode more than I use sports mode. I guessed that if I forgot to remove the hack (in cine mode) the result would be more dramatic, I’d be expecting slow and sluggish, but get fast and furious. Forget to remove the hack in sports mode and I’d still be expecting a faster turn of pace!!!
What I didn’t expect was for the drone to immediately turn upside down and plummet to the puddle. Wind was blowing from right to left, drone flipped clockwise, almost like it was trying to bank into the wind to keep steady.
Sports mode is always your get out of it in high winds so it’s always best to have this option when fing about with Atti mode
Indeed it is, which is why I automatically flipped to it, but forgot it was assigned to ATTI mode. Lesson learned!!!
Did you change any other parameters
Nope.
Plus I have flown with it loads since the meet without incident. To be fair I just think the windspeeds were too high, and I was being a dick! I knew I was pushing my luck with the wind to be honest so I’m not really surprised I crashed it. Was more surprised at how quickly it went down, no time to react all. As soon as I went into sports mode it turned upside down, and smasheypooh
Never, ask @clinkadink
I did think of another speed record to be honest. I know for a fact I could have broken the air2 record today, but I didn’t want to lose my drone
My tropical fishes are all called Bob. They tell you this if you can lip read, Bob, Bob, Bob…
Today was the first chance I have had to take the Air 2 out since I crashed it. Had to do a gimble calibration and snap the LED housing on rear right arm back into place, This was after letting it dry out and giving it a clean and blow down. She flies fine and the gimble is working as it should so I think I got away with it. There is a very slight whine coming from what I think is the rear right hand motor though. It’s not loud, but it’s definitely different than before. I can’t feel or hear anything when spinning it by hand, but these things turn at such an RPM only the slightest thing wrong can cause a problem. I can’t believe I never thought of taking the props off and starting her up, I’ll be doing that shortly, cheers for the tip @Kirky . Should be able to hear a bit better without the drone of the props!!! Other than that she is recording pics and video fine, gimble has full movement and all controls work as expected. Had 3 short flights and uploaded to AirData when I got home, nothing in there to suggest any problems
I think I have sussed out the reason for the crash.
After my test flights yesterday I plugged her in and connected to drone hacks to remove what I thought was ATTI mode. What I discovered is that I had set it to: 0 = Manual Mode (GPS position and Altitude Stabilization are disabled). Instead of: 3 = ATTI Mode (With Altitude Stabilization). So, I was flying in complete manual mode in high winds. I was only 20ft off the ground, but I was flying at a location with an elevation of almost 1000ft where the wind speed could have been much higher than I was expecting. When I took off in normal mode I was sheltered by a small hillock, I had to fly up above this protection to be at a decent height for the photo I wanted. So as soon as the drone got above the hillock it would have been banking to right and into the wind to keep position. I then turned on manual mode and with the drone already at 30 degrees or so, I think the wind just caught it and flipped it upside down. And of course once it’s upside down there’s only one direction it’s going.
Why did I set it to 0 instead of 3? I think I must have read the wrong information somewhere. I know some of these settings are different between models. I can’t blame a typo as the keys are too far apart on the keyboard to make that mistake. Either way, it was human error!!!
There is more to manual mode
Manual mode (allows flips and barrel rolls)
Change your “Sport” mode -switch to unassisted “Manual” mode. Fly only on open-area you are confident to train on. Idle is +50% and the drone will climb if you don’t respond with throttle down. This is essentially a RC-helicopter mode which traditionally have no FC/IMU and is solely defendant on pilot skill. When switching back to “Normal” mode, make sure that the drone is right way up and is not tipped over it’s horizontal or vertical axis. Failing to abide this will calibrate your IMU with the drone wrong way up and it will not automatically flip over. This is a sure way to damage your drone as it will fly towards the ground. can be seen here. Inspire Inverted Crash
yip, I just read that earlier this morning, which I think helped me understand what went wrong!!!
Lessons learned though.
Make absolutely sure you are getting your info from a reliable source and for the correct drone, then double and tripple check before loading into drone.
Don’t forget you have the hack.
Remove the hack when not needed!!!
