So after the m3p decided to flyaway from my hand and crash in some vines,i read the flight data and it says it was landing and suddenly changed to detour mode  and crash,so i believe was the obstacle avoidance that kicked in somehow.

If you would care to make the log public and post a link here then maybe someone will look at it for you and comment.
Ditto, alternatively download the "original" from airdata, upload that file to https://www.phantomhelp.com/LogViewer/Upload/ and post the resulting URL here.

At a pure guess did you try to do a manual landing (throttle closed) with the obstacle avoidance switched on?

If you'd like some help with data analysis and find an explanation for the incident, post a link for that Airdata report.
Make sure you've ticked the "share" box.

It looks like you were landing manually, bringing the drone down until it was just above your hand.
At 4:09.1 the drone made some extreme evasive moves, pitching 66° forward and rolling left.
In the last three lines of data, you pulled the right stick fully down to make the drone fly backwards, while pushing it to the right.

This looks like obstacle avoidance started things, but the incident was complicated by pulling the right stick hard.

My right hand was flat for landing,when it flew away  i pulled the right stick to stop it but it was already tangled in the vines. My hand From landing position to pulling the stick backwards  was fast but not enough to stop it.

Labroides,
Why would it fly into the vines if it had the OA on ?  Is that error on the part of the drone or the pilot ? Or can't you tell by the data?

Gentle GPS = obstacle avoidance on, is that correct?

Are the obstacle detection distances recorded in the log? If so in which column?

jerialyz's  log on phantomhelp = https://www.phantomhelp.com/LogViewer/0XOZXT5NVBQSWIPEH8E6/

Are fansb97e1cd6 and jerialyz one and the same person?
To jerialyz having Obstacle Avoidance on during a manual landing is a dodgy thing to do, I speak from experience of my first flight with an M2P. I assume you can switch obstacle avoidance off but if not by an app option then switch the droneto sports mode for a manual landing but use small stick inputs.

How close were the vines from where you were standing ?

Looking at the data, it rolled about 20% to the left, possibly just enough to face it away from the vines so the sensors didn't pick them up. There was also some Yaw input too at the time.

Just one wee thought, it's a bit radical but, the front and back sensors do not turn off once landing has initiated, do they?

Flight mode was in N Mode Bypass, i don't think it shows this on Phantomhelp, but It does look like Gentle is referring to the OA

Sorry for the late question.  Did you have to send the drone or only the log files?
