Just seeing this video, sorry for the late comment.

A way to negate the electrical noise with large props and motors is to choose a lighter prop.

Those look like HQ 10x4.5x3 which are about 24g.

The Gemfan 1050, which show much better gyro noise from mine and others blackbox logs, come in at 17g.

With a lighter prop you need less braking force as well so you could keep the PWM higher for the same effect or drop it to the floor for maximum braking force with less feedback.

every single videos are gold to me ; thank you very much for your work

[MCsCreations]

Excellent, Mark! Thanks a lot for all the tips! 😃
Stay safe there with your family! 🖖😊

have my roma f5 v2 set to 24/128k variable(mamba 55a 128k esc) feels nice. breaks well and im getting 7-8 minutes of flight time. I run my batts down to 3.6v/cell so i could go a bit longer. Ive learned a lot from you this year. Thanks for all the help

[martinchristiansson]

Thanks for good content.
Perhaps make a video on how active breaking actually works? With schematic on which FETS is on/off on comp pwm.
Would love that. Best R, Martin

Low PWM of 16kHz has more downsides from my findings than just bad video feed. I figured much more motor heat plus desyncs whenever clipping a gate.

Nice! I hope you get around to making a 4.3 2-pack tune video!

Do you have a great preset for my 3.5 grinderino with the 1804 3100kv motors?

[divingfalconfpv]

just realized my 10" esc was default at 48k low and 128k high.. just changed it to 16k to by rpm with rpm filtering now on.. Not sure exact different between 128k high and by rpm

[rubenvaneupen]

In bluejay it's just one parameter, not low and high. 48 is best?

Hi,
Im about to flash your 5 inch racer Preset with Medium build quality and 48khz settings.
What should I select in motor timing 16 or 23? And pwm low 24khz or 48khz?

Hi!
I Have had a problem getting nose dips after snap rolls, this problem does not occur if throttle (around 40%) is applied during the roll but every time if throttle is idle. What might cause this? Thanks im advance!

Hello
i am facing problem as i made a custom ESC, My motors mostly diagonal one becomes too hot. When i replaced it with my old mama ESC there was no Heating Issue

[serenestateofbeing]

I put mine to 24khz and i have never heard such horrible sounds coming from my quad. The trilling and occilations was scary, why cant i use 24? 5 inch normally on 48khz

[umbrela_Corp]

Hello from the future why would you not use all in one on such motors, 4114 400kv on a 4in1 for couple years now

[plop]

cpu load 72%, sheeesh =)
i was worryed about my 60% :P

[jkwilson]

Hi i have the foxeer Foxwhoop 25 hdzero version. I put this in a grinderino Frame and it has it set to 96k for the esc .Do i need to put it to 48k to fly better?

[arknan]

Hi, is that possible to have esc desync with 96k pwn.i have cineon C35 and at the first flight, i have esc desync so i put esc pwn to 48k and no esc desync

[MTB_FPV]

@UAV Tech - once i apply your UAV BF present for 5" and select 48k... do i need to setup low and high to 48k on BHeli32 or set 16k low and high by RPM?
