I'm new to multirotors, as I just partnered in an aerial cinematography business. I familiarized myself with the DJI WKM system, with thorough assistance from the business' former partners, and had a few great flights (no issues whatsoever) before my first job. I ran through pre-flight checks, calibrated the GPS, and had a couple of smooth flights with great landings before this:
I was flying in Atti. mode, and flipped to GPS Atti mode when the trouble started, but you can see that it didn't help much. I'm not sure what I was doing with the sticks, but I wasn't trying to fight it, as I immediately knew something was wrong with the flight control. Thankfully, the Octo landed in a bush and not on the rocks, suffering no real damage. We pulled it out, dusted it off, did a hover test, and another reasonable-length flight with no issues. After about 5 more flights it happened again, with a fresh set of batteries in a more dangerous location (unfortunately, we didn't get this one on video). I got it down onto a tiny patch of grass surrounded by rocks, cracking a gimbal leg and one prop.
I've been flying helis for a few years (including single rotor 3d), and have never had a crash like this.
Any theories on what went wrong?
Thanks!
