I’ve been flying for almost 6 years and never really bothered with “black box”. I recently built a 7” AOS I couldn’t tune myself. Someone online had been gracious enough to help tune via black box recordings. Can you do a video on what settings should be set up on black box. I’m using Inav black box for this build but all my other quads are BF, I’d like to delve more into black box. Shame on me for not doing this sooner! 😢

Thats great I think I need to look at the wobble method to take data for filter setup, because it looks very clean and interpretable...

It’s pretty cool. Works well on radiomaster zorro with convenient momentary switches

Do you use the wobble log for adjusting the filter weights?
@PIDtoolbox
@PIDtoolbox 24 дня назад
You can to some degree but still best to double confirm with a subsequent throttle ramp in the field. But certainly a good starting point

Amazing the quad did not freak out on the first test. How does the wobble script keep that quad on one spot? I would not trust anything in house like that besides my own control. It sure looks nice!

@@PIDtoolbox works wonders! I assume you give small stick inputs yourself to keep the quad steady.

Is yaw filtered by RPM? Or should it be 2 axes?
@PIDtoolbox
@PIDtoolbox 25 дней назад
Yes it is
@JLfpv
@JLfpv 25 дней назад
So maybe if you are prone to bashing props you could tune 250q with 50 weight so rpm filter would have wider target area to be able to handle the noise of chewed up props?
@TimeFadesMemoryLasts
@TimeFadesMemoryLasts 25 дней назад
i think it's the opposite. if you bang up your props you need rpm filters more. If your quad is clean enough and doesn't need as much filtering, you can ease up on the filtering as described here.
@PIDtoolbox
@PIDtoolbox 25 дней назад
I think DNs are always ideal for that
@JLfpv
@JLfpv 25 дней назад
@TimeFadesMemoryLasts yes but you can widen the q to hit the areas thst might not have been there with clean props. And have some delay by lowering the % attenuation. Idk?

@@JLfpv unbalance in the prop always sits right at the RPM number (and its harmonics). If you cut off a blade, the noise will still be at the same values of a pristine prop, it's just that the noise peak will be a lot higher but it should not be broader. But on second thought: In practice, because of the changed aerodynamics, maybe you have additional vibrations in the bent/broken prop that's coming from the additional turbulences which is causing broader RPM peaks...
