I want to take a minute to inform anyone here that is using UGCS about a software glitch that contributed to me crashing my DJI M300 into powerlines. I planned a simple mission that began a 120’, but then dropped down to 100’ for the “lidar corridor” part of the mission. When the drone began to drop down to the lower height, instead of stopping at 100’, she just kept dropping all the way down to 40’ where it struck a powerline, and plummeted to the ground (with my beautiful R2A in tow).
I sent the flight data to UGCS support team, and they shortly responded with the following 2 emails:
I don’t completely buy their explanation that “its a DJI issue” It seems to me like an issue like that should be solved with the flight control software. Also, the drone dropped 60 feet below the elevation that the flight trajectory path should have regardless of the fact that I had “safe” trajectory turned on.
They then sent out this email to all their customers:
In conclusion: I still don’t totally trust the software, I should have known how to flick the switch to regain manual control more quickly. I really just panicked and tried to override the mission using the sticks, forgetting that the sticks wouldn’t give me back control until I stopped the mission. If you’re a new ish user like myself, BEWARE.
