Thanks for the link guys. I'd seen his video on my feed at one point
So I increased my I a bit. went out and flew around. I have a 3S and 4S battery. The 4S is longer and on doing the throttle thing it's clear it drops backwards so I should increase my pitch I.
My angle mode is still wobbling but who cares about that.
Another thing I noticed is that when I punch and drop throttle to do a flip, during the flip, the quad seems to be still pushing a fair amount. The flips look more like small loops. And I also noticed when on zero throttle the quad doesn't fall as fast. So I figure my 0 throttle is still fairly high. What defines that? What makes it be that high? Do the PID's influence this?
Have flown FPV and I need to figure out how to make small yaw inputs be ignored. I'm just not on point with my throttle.

Edit: My current PID's https://gyazo.com/e38c5d6515d15bae194d4cac791f6a2b

what configurator software are you using? I am not as familiar with the views you show as I am with mine so I just figured I'd ask.

flips looking like small loops could have to do with camera angle... Do you happy to have DVR on your goggles that you could show? This might help with understanding what you're trying to accomplish

Still rooting for you bro... you'll get there!

Airmode is definitely recommended... if it's not on the mode page (or under "features" on configuration page) that probably means you're using a pretty outdated version of cleanflight.

Throttle being too high when stick is all the way down: lower min_throttle. Not too far though, usually at least 20-30 units above where motors start to spin reliably, when testing on motor page without transmitter (and without props, for safety reasons... i slipped one time pushing the motor slider, left a nice little dent in the wall lol).

To ignore tiny movements at stick center, you could increase yaw deadband. If it's possible on your tx, tightening the springs also can help.

Regarding the tail dropping with the larger battery, that sounds like a problem with center of gravity... increasing i-term should help, but it would be much better if you could optimize weight distribution by placing the battery more towards the front.

Completely agree about the CG. I bought some more little strips to move some things around get my battery closer in the middle, before I mess with the I even more.
The deadband I will have to look up, but I'll find how to do that.
About the throttle. If I lower it, will it have less control to keep it's orientation when changing min_throttle?
And I am using the old cleanflight version, yes. I posted a topic here to try and get my FC to work with the latest cleanflight, but after trying pretty much everything I installed the old cleanflight and it connected without a problem. Soo.. yeah. No Airmode. Maybe it used to be named differently? Or is it fairly new? There are a lot of modes available still.

Big thanks for keeping an eye on this thread and helping out. I'll keep updating. OW, almost forgot! The loop thing is the easiest to see in LOS. It literally looks like the 4 motors are pushing it into a loop, where you'd expect it to just use the 2 to make the flip and only power the 4 to remain proper orientation.
I did a roll flip in FPV and didn't really notice, because I'm mostly lucky getting a full role and keeping control of the quad after that.

Hm if i remember right, back then before airmode was introduced, there was only full PID control when throttle was above min_check. To not risk instability at "zero throttle", people used an idle-up mix so throttle couldn't get below min_check while flying.

Also default min_check is usually pretty high... if your throttle channel goes down to 1000, you can lower min_check to about 1020 (you need to be able to go just below it in order to arm the motors).


Regarding the version... yeah i know the latest cleanflight causes trouble on many configurations, but airmode was introduced long ago. I think there should be newer versions that still work with your setup AND have airmode, i think the last ones before the big changes were 1.9 or 1.10?

I will check if I can install either of those to test later. I've moved my receiver and the battery is in the middle now. It still falls to a side, but a lot slower now. Haven't checked in fpv mode yet. I accidentally pulled the end part off of one of my receiver antenna's. Is that a big deal? Should I replace that one with a new wire? My min_throttle is pretty high at the moment. So I would have to lower that. I hope the PID's will still do their job.

About to look for a group of RC planes pilots in the area, hopefully I can join those in flying

I can not believe it. So I started messing about with cleanflight again. Try installing other versions. Try to find any other people with different problems on the same FC.
Tried flashing again for twenty times with different settings, strap the boot pins, try some more stuff. Pretty much the same thing I tried weeks ago.

At one point I press the flashing button again and it just does it. IT JUST INSTALLS IT. I'm so annoyed, but so happy it finally worked. I'll have to set the modes again, but I have air morde and such now. Hopefully I don't crash it now, before I manage to tune my PID's
I'm just so happy it has the latest version now.

You have to follow another step that isn't listed in the manual.. believe you have to check manual baud rate and set it to 115200 but I found that step online somewhere.

Did this board come from Banggood? I had the same issue when I got this board, wouldn't flash with default settings. Then I set manual baud and it flashes easy.

Same thing with betaflight I had to set manual baud rate.

I pretty much tried everything and it just flashed with automatic baud rate. It did set to 115200 by itself.
I honestly have no idea how to fix the issue if I run into it again

Edit: And yes, banggood.

w00t! worth it to have it flashed... hopefully the update will get you a little more sorted.

I have same board.. same issue. Next time set manual baud to 115200 and you'll have no worries as long as the driver is in place. Goodluck with the setup + flying.
