X racer F303 V3.1 how to do 8K/8K?
#1
I currently have the X Racer F303 V3.1 with Betaflight 3.0.0 RC4 and I am not able to run 8K/8K on it. 8K gyro update and 4K PID looptime works fine with a CPU load of about 19% but 8K/8K brings the CPU load to over 100%. 
Is there anyone that runs this FC with 8K/8K? if so, maybe you could provide me with a betaflight dump so I can compare with my setup?

I fly 3.0 xracer and I think I've set 8k/8k synced - I'll have to double check that as I was in a hurry. But I run 3.0 firmware posted by the manufacturer before 3.0 RC1 actually appeared on github. Are you interested?

Thank you, that would be really nice if you could post a CLI dump here. Take your time, I'm not in a hurry. I just got to test the quad yesterday and I'm not sure if it is Betaflight 3 or the FC, but on stock PIDs I have never flown such a locked in quad! It felt almost unatural how fast it stopped when rolling and flipping and not the normal overshooting and small oscillations I am used to

I'll dump my settings today evening.

My quad actually behaves badly on heavy props, I was able to tune it out on triblades gemfan 5040 (great prop btw, pity they break that easy). I had to fiddle with filters a bit though as my cobras took their share of hits - or maybe they are just too weak for triblade HBN ;p

As to a super tune out of the box - I think Boris is to blame Wink. My backup quad flies like a dream on old naze32 rev5, perfect machine, absolutely no bounceback, almost no propwash, I could probably tune it up a bit, but it already flies so well I don't really want to change anything!

But I have just one question - if it flies so well, why do you want to go 8/8?

Haha, I always give the same answer to my friend when he asks stupid questions Big Grin

Here's my dump, as I said that's hex file downloaded from fpvmodel, not BF repo

Code:

Thanks Konrad. I did a compare, but could not find any major differences. I did an update to RC7, and now I am able to run 8k/8k. The changelog also tells something about this on the releases after rc3, so I guess it was just a bug or non optimised code

8k/8k with accelerometer brings the CPU load to 80-90%. Is this ok?

Good to know you found the issue.

that's 80-90% when it's idle, this is not safe. It should be below 40%. Try 4k/4k - you won't notice the difference in level modes and only marginal difference in acro.

i would like to use 8k/8k unsyned too, but the CPU will be more than 60%, is it OK? im using v3.1
I am still not sure what is Release candidate 7.. this is update i have to make on betaflight..?

If you're using the latest BF3.1 builds (802 and beyond), you should be ok with 8k/8k on F3 FCs. Disabled acc if usage seems too high.

BF3.0 Release Candidates is a thing of the past, there's a final 3.0.1 version of quite a long time, and 3.1 dev builds.
