PID tuning help! ZMR250
#1
Hi there guys, i need some help with tunning my quadcopter as I'm new to this. 

My setup is:
ZMR250
Naze32 rev5 running betaflight
Dys 1806 - 2300kv
RHD 12A ESC's with Simionk (don't ask me why I have these ESC's Big Grin )
Gemfan 5030 props
Turnigy Nano-Tech 1300mA 45c 

I recorded a video with my GoPro and uploaded it to youtube and below there's a screenshot wit my PID values

looks like you have some oscillation (too much P probably?) and bounces (D too low)
try lower P first see how it goes, then worry about D later:
roll P 3.5
pitch P 4.2

Thanks for your reply Oscar!

Today I started tuning with I and D at 0 and started upping the P, and after the I and the D. From what I notice, the roll wobbles slightly and the pitch wobbles quite a bit more than the roll. I also noticed that the quad has a bit of wobble at low throttle.

If I had blackbox it would be much more easier for you guys, but that's all I have right now, so sorry  Sad

Anyway, here's the video and my PID's:

Thank you! Big Grin

Another thing: If I add some low pass filter will the wobble at low throttle dissappear?

LOL i can't see your PID man... the IMGUR uploader resizes the picture to 600px max... maybe just copy CLI using "code" button in editor...

Like this?

Code:
set p_pitch = 63
set i_pitch = 40
set d_pitch = 47
set p_roll = 57
set i_roll = 37
set d_roll = 45
set p_yaw = 90
set i_yaw = 50
set d_yaw = 40

that would do.
Your values look a bit unusual... maybe try this

set p_pitch = 55
set i_pitch = 45
set d_pitch = 22
set p_roll = 50
set i_roll = 37
set d_roll = 20
set p_yaw = 100
set i_yaw = 50
set d_yaw = 5
