Someone who lives nearby contacted me through my website, so I went to his village and made this video with a demo of the Wookong's return home and auto land at the end.

Crashing the Aeroxcraft Quad-670 with GoPro Camera Gimbal


Having a go at filming an old abandoned diesel roller and it all going wrong.


I glanced to the side at exactly the wrong moment and flew into the slope. 100% pilot error!


Damage report:
* Tilt servo gears stripped
* Roll axle bolt bent
* 3x propellers
* 2x motor bearings
* Landing gear spacer plates cracked.
* Scratched DJI GPS unit
* Dented pride.


The gimbal did it's job and the GoPro camera hasn't got so much as a scratch on it.




No video post stabilisation, just edited from raw footage.

Heh, oh well. I had a little crash myself yesterday. When I started it used to be something that happened pretty much every time I went out, then every week and now it's my acolyte saying 'it's been a long time since you've crashed anything...' . :)

P.S. Your footage looks good though, I might try that setup sometime seeing as it's not too expensive.

Only yesterday I was telling someone that 'I do not crash much these days'. I thought it was tempting fate saying that.

Keeps us on our toes. Every time we have little crashes like this it becomes less likely we'll make mistakes when it matters more.

A Early Morning FPV flight with the Wookong M on a Droidworx Y6 Frame .
Raw video shot on the gopro 2 (hard mounted ) at 720 60fps , no post stabilisation or camera gimbal used.
Please excuse my trainers in the garden , Our new puppy keeps taking them :)

Brilliant. Perfect morning for flying...... Trainers? I thought they were a couple of canoes you had in the garden:frog:

Interesting that the props are still visible even with a Y6. I have often wondered whether those lower props in a coaxial would be a problem. Strangely it appears that with such a wide angle lens the coaxial is actually more restrictive than a flatty.

Fly,crash,glue,repeat!
Nice flight Geoff.
My wifes mum used to live a bit further up from where you flew,at Jones Farm on Dawson Ln.
Did you go LOS for the landing ,seeing as how you reversed into your garden?

Yes the landing when reveresed was LOS because it is very tight coming into the garden with all the trees here etc .
And props are only visible because the gopro was hard mounted , if a gimbal would have been used then props would not be seen .

Kudos for such a lack of artifacts with a hard mounted GoPro. Those things look for the tiniest excuse to wobble the video so your airframe has to be really nicely balanced to get such a clean image.

Yes it is a very well balanced machine , Im getting to like the Y6 configuration more and more I fly it ..

Here is a first attempt with some post stabilization:

Here is a first attempt with some post stabilization:

Nice and smooth but the horizon is off the whole time. This can also be adjusted in post, with time and consequent further loss in definition, or the gimbal can be adjusted so that the camera is level. Were you monitoring the video output or just flying around with the camera recording? The non-level horizon would have been noticed immediately with a live video monitor. But use the camera output, not a separate FPV camera that only gives an approximation of the framing.

Yes, I noticed that as well. I will have to explore that issue further and look into the FC gimbal controls (although I thought I had set it up to be horizontal). I didn't have any video downlink so yea, I was just flying blind.

If there is any sort of wind around when you are flying the MR will tend to lean into it - same with helicopters. The MK FC camera control does not handle this well and after initially correcting the camera's horizontal it then starts to follow the MR's attitude, as though the new lean is taken as the updated horizontal and level attitude.

Swinging the MR from side to side the MK camera stab works fine and it is often difficult to see the horizon budge at all. But an extended sideways slip, or hovering and flying in sufficient breeze to cause the MR to maintain a constant lean into wind, the camera plate quickly leans in the same direction as the MR and the horizon then has to be corrected manually.

I am actuality using the Hoverfly Pro FC but I sense it has similar problems to the MK in this regard. I went back and looked more carefully and the problem gets worse by the end of the shoot. I will redo the bench calibration on the gimbal controls and see how it goes.
