Tiny Whoop Video Feed Fuzzy When Trhrottle
Tiny Whoop Sluggish Throttle Response/Oscillations?

I've only flown for about 3-4 days, I built an Acrobee with a BeeBrain Pro and Crazepony 0615 motors, stock props, cockroach frame, Project Mockingbird tuning. A lot of the time (almost all of the time) after a flip or roll it seems like my throttle is slow to respond. I chalked it up to technique for a day or two but then I noticed what I'm guessing are oscillations on the descent? I know there are oscillations that become an issue with the video feed but do they coincide with oscillations in motor speed? I feel like it must be in the tuning somewhere, even though the PMB tuning really opened up the quad and made it way more responsive and easier to control.
I'm still learning how to tune but is there a speed or setting I can adjust for this? I remember I had to adjust thr_corr_angle and thr_corr_value in the CLI per the Project Mockingbird page so maybe I need to adjust that? The throttle response feels great until I try to do a flip or a roll and then it just plummets no matter where I put the throttle. When I first arm and punch out its almost alarming how fast it can climb, but then as soon as I start to move in any lateral direction it loses a little, and then a flip or a roll just completely drains whatever is left.
EDIT: I just looked up the motors in my amazon transactions and they are Crazepony Insane (19000 kV) so they should be sufficient I guess?
Also I don't know what kV my motors are, they were some of the first things I bought almost 2 months ago when I decided to get into flying and didn't know enough to retain that info. I do know they came in Crazepony packaging but the sticker said Racerstar or vice versa and I want to say they were 16,5 or 17,5 but I'm not sure. Maybe they're just not enough for the quad and the only solution is to buy plaids or gold at least.
I may try backing up my current settings and tuning from scratch to learn how but if this is something that is super obvious to a veteran pilot I'd be happy to know what it is.

what batteries do you use?
if you mind tuning, emuflight could be a try. its a fork of betaflight, matching whoops better by default and there are some tuning presets.

Sorry for the slow response, I'm using RDQ 380 Li-HV batteries. Not long after my original post I started having VTX issues and I've been dealing with that.
I went back to the stock config and the problem disappeared so I think it's one of the PMB settings that caused it, possibly the D Min gain or advance.
I had already been looking into emu flight so I will give it a try tonight. What about it makes it that much better for tiny whoops?

video noise cones from high d-values.
emuflight is the evolution of project mockingbird - somehow...
the experiences from project mockingbird flow into emuflight, one important man from pmb is an emuflight developer.
emuflight does match micros better by the defaults, it even provides a bunch tuning presets... it suits better by default on micros or other kinds of "unusual" settups.
betaflight defaults are focused on common 5inch quads, it shines there.
the presets and the general knowhow and focus of the developers makes the difference.
overall we can get a good flying quad on both its a question of settup and work. there are some different features. emuflight is the better software to startout on a whoop and better to stay on defaults or presets.
overall emuflight is still a fork of betaflight 3.5, it provides benefits of betaflight 3.5 and provides improvements and features.
if i am right, rdq lipos are rebranded gnb lipos, these are top micro batteries... it wont be the source of an issue, no ability to improve there.
Awesome info, thank you!
And yeah I think say gnb on them. I plan to learn to tune from scratch but as soon as I got ready to start is when my VTX started acting up so I wouldn't have been able to fine tune it the way I saw on YouTube.
I'll definitely look into emuflight first though. It's already downloaded and everything so it shouldn't take long.
