For those that aren't already aware, it looks like there might be a filtering issue in Betaflight 3.4 which is causing motors to burn out, particularly on micro quads. Albert Kim has posted the following video warning of this potential issue...

Good to know. 3.4 hasn't caused me any issues but there are a lot of people that have had major issues. I wonder if this is related to the earlier JB video about overheating motors using an older configurator? I've seen some reviews from people that had issues with 3.4 trying 3.5 and it seems like 3.5 will be the version to clear this up.

I think the problem is that we are used to our quads flying OK with BF default settings, and that isn't the case anymore IMO. I have 3 totally different quads (3", 5" and 6") that flew nicely. Just updated to 3.4 and all 3 came down with motors super hot. Same with 3.5 Seems we were on a trend for a while where BF was becoming more user friendly, that trend seems to have reversed now. My only suggestion to anyone struggling with getting a decent tune is to read the Github tuning tips. over and over...

Hard for me to comment on this as I only have one 3" quad running 3.4 but I'm not experiencing this currently. However, I'm not running the stock tune, I backed up my config and loaded it back in after updating. I'll have to go burn a few packs soon and double check.

Thanks for the post SLFPV, and the link RENOV8R.....oh, thanks for the headache RENOV8R, that GitHub link did me in....

Thank you for the PSA! I loaded 3.4 onto The Bug on Monday and had been trying to tune out the overheating 1106 motors. Never were an issue before...suddenly they are :/ Well, 3.5 should be here soon enough.

Hmm I have 3.4 in my 5" quad and 3.4.1 in my tiny whoop URUAV UR65 and I have no issues whatsoever - I'd even say that at least on the 5" the motors are now less warm even though I'm doing more crazy stuff with it. I can't compare the whoop since loading the 3.4.1 was the first thing I did when I got the quad, but even when I was flying outside and punching quite a lot, the motors were only slightly warm.
So I guess it really depends on the exact setup and tune. Also I have to say that in both quads I started with a stock tuning and followed the guide in GitHub to tune it a little.

I haven't had issue with 3.4 on my 5" quad. No vibration/oscillation issues, motors are not hot either.
There was a bug in the older configurator related to incorrect filter default value. It was fixed in the latest version.

According to JB in his latest video, this filtering issue affecting micro quads should now be fixed in Betaflight 3.5. Click HERE to hear his comments on that.

im using betafligth 3.4 with my 5'' quad since a week ago or so and i havent any problems with it. in fact, it flies better than with 3.3 with stock pids and filters on both

Flew a half dozen batteries in 90 degree heat today and no hot motors on 3.4 for me, only slightly warm.  Maybe I have something turned off that others have turned on?     Guess it won't matter if 3.5 resolves it.
