Crash during an experimental flight

[Azarov]

Test flight which lead to a crash.

I set up a test flight in my backyard.

Here is a feedback on my drone crash today

• The situation happened in my backyard with some obstacles surrounding the area of launching and landing
• The Mavic 2 Pro was in a disabled obstacles mode
• I didn’t hold RC at the time when it happens
• There might be a light wind which start drifting the drone
• My instinct reaction was to stabilise the drone
• But it get worse
• And the drone crashed against the poll in my front yard.

Lesson learned

- Disabling of obstacles mode is a very risky operation. Unpredictable to happen, for instance when you’re flying inside of a house.

• When the RC is out of control the first instinct must be to land the drone! This is must be an instinct.
• Don’t try to save the drone by putting yourself in a dangerous risk of being hurt by the mechanics of the drone. Power, razor of the blades are very dangerous. Don’t use your palms and fingers. Stop it by using your RC. You can do it.
• Another option is to catch the drone by your hand if it is within your reachability.
• Never leave RC out of your hands assuming the automatic control system of the drone can cope with unpredictable.
• Experimenting with the drone’s capabilities must be planned very well. Have a lot of safe space around so you can cope with unpredictable behaviour at least with some degree of confidence and predictability. Have a back with your friend, colleague.
• It appears that someone can purchase a drone jamming equipment on the black market. It becomes another factor to take into account.
  It is illegal in a civilised countries. But can be brought from uncivilised countries in. In a civilised country the issue with a drone regulation, noise, privacy etc. are regulated by the law and citizenship’s feedback.

My instinct reaction was to stabilise the drone

How did you attempt to stabilize the drone if you weren't holding the remote controller?

Never leave RC out of your hands

This is great advice any time your drone is in the air.

One piece of advice: You have to be careful about rotor effects. If there is some wind, then you have houses and walls around yards, and what can happen is that you get a rotor vortex (turbulent flow) coming off the house or a wall, and it's very hard to fly in those conditions. You can have an instant crash. These drones can usually fly in a fair amount of wind, but you want steady wind, not turbulence.

I jumped to the RC to hold and control but it was milliseconds when you're out of control of your equipment.
The best I could do is to press left stick down to land it.
But I didn't.

Lesson learned

Some better lessons to learn:
Avoid flying close to obstacles.
A light wind doesn't make your drone drift
Drone jamming had nothing at all to do with your incident

I didn’t hold RC at the time when it happens

KEEP THE RADIO IN YOU HANDS!!! You are lucky you didnt hurt someone or yourself!
What were you testing anyway? You were not "jammed" BUT yes the equipment is illegal and VERY easy to get.

KEEP THE RADIO IN YOU HANDS!!!

Yes, that's the real lesson here.

If it was drifting in a light wind you had no gps signal lock.
