Today was a very bad day for my copter
My friends and I rented a car trip
from the start the problems started with the remote control and the phone connection:
Turn on the drone, turn control - gps catches on the console is written ready to go but when I connect the phone says error RC nesskolkih after rebooting the phone and the remote link appeared.

I installed the drone to the ground, he has caught the signal recorded Homepoint, I have tried to indicate that the remote Homepoin but he has shown an error.

Next we went to the car and filmed the trip primerono within 1 kilometer link again wrote mistake copter swung and a bullet flew by us in homepoint, poksolku road was meandering in the way he had the trees and the drone at high speed crashed into a tree and then there hung.

Damage:
1. broken landing gear leg
2. The broken glass gimbal
3. scratched dent on the second leg
4. broken all 4 screws



Actually I understand what were my mistakes but also to the DJI I have some questions:

1. why, after a loss of communication drone can hang 30-60 seconds to restore the connection, if the battery is sufficiently charged (in my case, the charge was 80-90%)
2. why the return takes place at such a high speed if the distance allows, and charge the battery?

soon I'll post video of the flight and fall, and error logs.

So many questions...

Was the Return to Home height set correctly?
Was all that damage really cause by it getting hung up in the tree, or the process of trying to get it down?

Not sure I would try to control a drone from inside a car.  Especially a higher-end one like a Rangie that likely has solar glass which could significantly limit signal propagation.

Sorry for your loss.  You had some nice video going there up until the crash.

The RTH height looks way to small. Please note that the RTH height is set based on the home point. If you start moving away going upwards, the drone can be 2m above ground but 50m above home point. In that case it will keep the height of 2m and fly back. I think it was written in the manual, that tiny obstacles like wires or branches might not be detected properly by the obstacle avoidance system.
I have also noticed that the RC connection to the drone gets weak when I am close to a car or inside a car.

This should be written inside the plastic parts somewhere for recycling reasons.

Friends I glued his mavik)

Used with epoxy MOMENT, as a bandage of elastic bands for money

make a photo before and after gluing, can someone come in handy)

Test flight was successful, rising to a height of 300m and fly to 1km, returned safely)


Regarding loss of RC when it was just in the program DJI GO, symptoms are: constantly disconnects the connection and complains of loss of RC, bullets writes the Check APP, you come to the program and it says Disconnected, is solved by uninstalling the program, cleaning all folders with the word from DJI and a new install (after these manipulations, the problem disappeared)

Сергей, подскажите, после того как заклеили луч в процессе дальнейшей эксплуатации проблем не было? Имеется аналогичная ситуация как у вас: задний правый луч в том же месте.
