Guys everytime I drop my throttle my PIDS go all crazy. I'm getting a pretty constant wobble as well. I know a lot more info is needed but off the cuff what do you all think?

maybe you can just post your blackbox log? can't tell much just from that screenshot

What could cause the PIDS to be dropping out every time the throttle is low. As long as i stay on the throttle its pretty locked in. I am in Airmode too. I don't have any blackbox from my latest tune it helps to have the SD card installed in the FC, duh.

UPDATE: Here's the most recent Black Box

I really don't understand how you have this craft tuned....

These PID values seem to be ridiculously high.

I'm not sure what you mean by "PIDs dropping out".

Oscar · 12-Jun-2017, 03:02 PM

LOL... yea those PID values are a bit extreme... Big Grin

I will take a look at the BB log when I get home

RENOV8R · 12-Jun-2017, 04:25 PM

I wouldn't fly until you get some input from Oscar. Those D settings on pitch and roll are quite high, I'm guessing your motors are getting pretty hot?

Oscar · 13-Jun-2017, 12:11 AM

PID are way way way too high !

Try this values instead for the start

Roll P 55 I 45 D 20
Pitch P 65 I 55 D 25
Yaw P 90

report back if you can Smile

Play with Set Point weight (0.7-1.0) before further changing D Smile

Your quad is pretty clean of noise, so it should fly relatively nice Smile

and you are lucky you haven't burned your motors yet LOL

Thanks for the info!

I'll give these values a try and adjust the set point weight of D.

Trust me I understand what you're saying. I have had very similar PIDS to what you have suggested and the thing flies like garbage. My motors aren't even getting a little warm which also surprised me. So I just kept cranking things up and up. I dont get it. It's probably just time to get new motors. The esc maybe have 10 flights on them. The board was just installed Saturday. Everything sounds smooth but who knows.

Dropping out isn't the right way to say it. When I let off the throttle control sloppy and the quad bumps around like the PIDS arent doing anything. Get back on the throttle things are better. This is not my only quad. MY x210 is tuned pretty solid and flies great.

Oscar · 13-Jun-2017, 01:04 AM

you are using 4S right?

Yeah 1300 4S

Drone0fPrey · 13-Jun-2017, 07:31 AM

What is your min_throttle set to? Could it be too low and allowing the props to slow too much?

DOP that's a good thought just checked it an Min is at 1065

I'm going to try Oscar's suggested PIDS this morning and report back with the blackbox. Thanks for all the help!

UPDATE: Here is the latest blackbox using Oscar's suggested PIDS. I dont know what the heck is happening. BlackBox

UPDATE: I've confirmed through an unsafe method, that the number 3 motor is cutting out during flight. I'll pop some good motors on and see if that's the issue or the esc.

Guys I think it's a lost cause now. I reset EVERYTHING back to stock betaflight and now its tumbling out of the sky. It willl fly for a second then it just goes crazy. I'm thinking all this could be motor related. One motor sputters on start up and MIN throttle is 1070 its more than enough so I'm thinking that motor is cutting out mid air. I appreciate all your help but I dont think we need to waste our time anymore I'll get it figured out eventually.

Good news is its my old quad I was just trying to keep in the air.

Drone0fPrey · (This post was last modified: 13-Jun-2017, 03:48 PM by Drone0fPrey.)

I see min_throttle set @ 1020 in the dump you shared. But that does sound like a motor or ESC problem or even maybe ESCs need calibrating or solder joints checked.

Just some brainstorming Wink

I hate it when a quad isn't flying Tongue

Hope you get it figured out, who ever said an old quad can't learn new tricks Wink
