Hi

I have been trying to find PID settings for a 180 size quad but can't find any really good ones online.
The vehicle set up wizard doesn't have any for 180 size quads(unfortunately).
The ones I have now aren't very good(but at least they work)
Is there anyone who has PID settings for my quad.(180 size please)
Any help would be appreciated.

Use tx pids option if you don't have a revo, or autotune.

If you got pids that fly without vibs use easy tune to tune the pids

Like mentioned use EasyTune in general or AutoTune if you have F4 hardware, but always check if AutoTune result make sense, it's not suitable for blindly running.
About PIDs for 180mm size, that is not realistic to have. PIDs depend on battery used, size of props, motors, total weight etc.. There are too many factors to have PIDs just for 180mm size, so sadly you do really need to tune yourself. And best results are by tuning, not by using someone's PIDs. If default PIDs work fine, then it's just coincidence.

I would use auto tune but I only have two flight modes on my controller. I can't figure how to do it with two.
Is there any way to do it with two flight modes it and how.
Thanks in advance for the help.

You need at least two flight mode positions assuming you cannot takeoff in Autotune.

FM1: Attitude
FM2: Autotune

- Takeoff in Attitude mode - Bank1 (FM1)
- Switch to Autotune (FM2)
- Wait for one minute (shaking)
- Land - Disarm (New autotune PIDs are copied to Bank3)

Next you can check/copy the new PID found in bank3 or simply use it with Attitude for testing
FM1: Attitude + bank1
FM2: Attitude + bank3

Thanks everybody for the help.

Now I have run into another problem.(sadly)
I set FMS1: to stabilized 1; FMS2: to autotune
Now I get an error.(attached pic)
What am I doing wrong.

I don't notice where you said what kind of FC you have.  AutoTune isn't available on CC3D.  Use EasyTune if you have an extra channel to tune with.

[f5soh]

What am I doing wrong.

You cannot run Autotune using a CC3D

Previous post highlighted the config issue you have, i mean try to run Autotune with a CC3D.

Use tx pids option if you don't have a revo, or autotune.

or AutoTune if you have F4 hardware

[I_drone_about_drones]

Okay I do have a CC3D so autotune won't work.(Thanks for telling me)
My problem now is That I have a spectrum DX6i which does not have any wheels or accessories other than switches.
And I think means TxPID won't work on my transmitter.
Even if it did, I can't seem to any accessories add them in the transmitter setup.
Is there any way to tune my quad beside just comparing different PID banks on my two flight modes.
Thanks.

[TheOtherCliff]

I suggest you Google
OPTune

That is an old manual way where you manually adjust PIDs till you get small oscillation, then a formula tells you all PIDs.

Either transmitter with knobs, or oplink modem and Bluetooth dongle + Android phone. Alternative two oplinks and laptop. You need to tune these values some way.
Dunno about OPTune but if Cliff says so then it must be possible. It is cheap to get 2 oplink modems and ask someone with laptop to assist changing values while you fly. I haven't done that though. Android app has PID tuning panel and is nice as you can attach phone to transmitter. Choice is yours

 I have another question.
The reason I thought my PID were out of tune was
1. When I fly really fast forward and bring the drone level it automatically stops itself.
2. When I descend the drone wobbles.(but I think that this is just a librepilot thing)
And another totally unrelated question,
How do you increase the roll and pitch speed.(I have an idea how to but I don't want to mess things up)
Thanks.

I am not sure what you mean by 1. motors stop ?
About 2. your optimal PIDs might be narrow, in my case it happens on big F450 copter, it wobbles at high and low throttle. There is option TPS (Thrust PID scaling) which adjusts PIDs to throttle value and solves this problem on quads having it. Though I haven't seen this happening on smaller builds. Yesterday I finished 80mm size one and didn't even tune it, flew FPV between rooms feels just fine.

Actually bluetooth dongle you can hook up directly to CC3D without need for OPlink, sorry for confusion. Check wiki how to do that. Dongles are very cheap and it's realy nice to have, if you go to the field with goggles, batteries, copters and realized you forgot to change "always disarmed" But it's a 20min bike ride back to home Also app shows system health, and allow changing many options. Really handy and I recommend it.

OPTune

OPTune requirements should be the same as EasyTune because you need to find the small oscillation using a knob and TxPID.
Anyway you can find the small oscillation by trial and error / land connect to GCS... it must take some time

The wobbles in vertical descent phase are almost normal, just physics. Drone descend into his vortex.
You can do fast descends without wobbles if you go a little forward and doing circles.

You can take a look at wiki pages for how to change speed settings, for Attitude mode:

Rate mode:
