Why going through the hassle of preparing special branch? Couldn't it be merged and guarded by a preprocessor build flag? And then enabled by adding that flag to the cloud build. That would then save you the hassle of rebasing it on top of bf every time.
Yeah, Sir, im planning to PR some features back to official Betaflight. But not all of them deserve to be there. So this is sort of experiment branch to test, to check what people think, what developers think, etc. Plus, a separate branch can be updated faster, no need to wait for official BF release. Can still use "stable" 4.4.x + extra features required. And this is essential, for this season racing, for example. Not everyone would be willing to run 4.5 unreleased. But many people need RPM limit, for example.
@IvanEfimovLimon fair point with the rpm limit. I just think these features are so good they should become a standard 😀 like post flight stats or quick menu
Could you use this RPM limiter if running non-matching motors? Like for those times when you bash a motor and that model is no longer available? (As long as same number of poles of course)
Ivan, I've input my motor's unloaded kV from the manufacturer and it feels like the limit is too low off the blocks and feels better once it's calibrated in the air. Should i input my motor's loaded kV knto this value? Surely there is some guesswork in calculating the real motor limit using the unloaded kV?
@@mopatop3921 its just guessing based on kv you input, but guessing can be off depending on your motors/props. Tanner (RPM limiter inventor) have some plans to imrove guessing. But for now you can just put in the settings whatever KV would feel natural for you. In racing the guessing stage is really short cuz you hit full throttle right at the start. But for freestyle scenarios, yeah, you might want to adjust KV if it doesn't feel right. This KV in the code is just a multiplier in the guessing equation.
What is the CLI command to set motor kv for this limiter magic? I have it all set but the CLI in the tuning notes isn’t working for me. Unknown command error
I was hoping someone would explain this because i noticed it was on my spec 7 i flashed for street league. In that case, turning it off just made motors more hot but for now i accidentally got higher pitch props probably not helping.
When I try to flash every time it says "No response from the boot loader, programming: FAILED". Is it even possible with my f4 flight controller? (The Happymodel Pancake AIO F4)
Yes sir, should be possible. You might need to do a trick with boot button. All the troubleshooting steps for flashing BF that I know I posted here: th-cam.com/video/AqsOBHyEFMk/w-d-xo.html
Just to let you know. The KAACK Special release in the drop down menu in Betaflight Configurator says 4.4.2, while the software when installed shows 4.4.3 in the top left corner of Betaflight Configurator. Confused me for a second but it's the same here in your video.
Appreciate this version a lot. I still have 3 quads with F4 boards (Synergy F4 boards). I'm locked at 4k pid loop and Dshot 300 with RPM Filter. Previous version 8k/8k was available and worked fine. CPU was high but never had an issue in my experience. I also just tested on another F4 board (CLRACING F4) but the 8k/8k is available there. Looks like same CPU's but not sure why the synergy is limited? Any input? Thanks Ivan!
@@IvanEfimovLimon Unfortunately only DSHOT 300 can be saved. If you choose 600 it defaults back. Again, on another F4 board, i can select it just fine and it works just fine. so weird. previous versions its fine but on 4.4.2 its doing it as well not just kaack version
@@IvanEfimovLimon Thank you for the quick response. That video of JB really had me worried as I have 4.4.2 on my long range quads... I'll flash your version on it just to be safe. They made it seem like 4.4.2 was unsafe.
@@InfinityDrones 4.4.2 got some dshot problems with some ESC firmwares. If if you running blheli 32.9 you are good mist likely. To make sure, spin motors (props off) from motors tab, from 0 to 100% throttle and watch that errors are ~0%
@@IvanEfimovLimon I'm running a mamma mk2 stack with blheli S - needed to do motor direction in esc configurator and flashed Bluejay 19.2. Not getting any errors at 100% throttle in betaflight motors tab.
This is really cool. But there’s something kinda confusing about it all. If you can specific RPM limit, then why do you also need throttle cap, or any other info? Not sure I understand why you say “BF doesn’t know anything about your motors” when if you put in max RPM then isn’t this all that’s needed?
When you activate RPM limiter, then throttle limit is not shown in prearm screen, and not working. Motor limit is still valid tho, if you set it. In this implementation of RPM limit it really just guesses your desired throttle cap till you hit full throttle. And once you hit full throttle it can compare your max rpm setting with the actual RPM.
but why does any of that matter. If you set rpm limit at 18000, and BF knows actual RPM, who cares about throttle? I don’t see the relevance. The RPM limit is the cap, no? Maybe I’m missing something so my apologies for the stupid comment 😂
@@IvanEfimovLimon let me rephrase. If you have an RPM limiter, you don’t need throttle cap. BF sees RPM, and if a motor RPM hits your set limit then it just has to stop it in its tracks there by feeding the info back to motor output, irrespective of what the throttle stick is at. At least that’s how I thought this would work. Maybe it’s more complicated than that and im not understanding it. My apologies if im driving you bonkers
@@PIDtoolbox no worries, it's good to have second perspective. With RPM limit you indeed don't need throttle limit. Because rpm limit is basically a smart throttle limit. But you might still need motor limit. Just like with a regular throttle limit, the RPM limit only limits the average rpm across 4 motors. So some of the four motors can still spin faster than your limit, as long as the other motors spinning slower (making average at limit) So it's not limiting the rpm of individual motors. It's limiting the sum of motors rpm. So if you run crazy high KV motors that can burn with 100% motor command, you might consider adding motor limit still, despite you have RPM limit. In theory it's easy to make RPM limit to act like smart motor limit instead of throttle limit. But in this case you might also need to dynamically adjust your PIDs, just like you have to adjust pids, if you set your motor limit to 50% let's say. That's something still to investigate :)
@@IvanEfimovLimon ah I see it’s averaged RPM limit. Why couldn’t it be made to have RPM limit for each motor? In either case it can affect PIDs but only in extreme moves where one or more motors might ceiling at the RPM limit and affect the copters ability to have full pid control but I presumed no one wants to limit RPM by some severe amount so the effect on pid control should be minimal. Alternatively the pilot could tune with RPM limit on to be accurate. The devs know best I’m sure they thought of everything 😜

StreetLeague RPM limiter is more advanced. It has more feaures and its smarter. But yeah the idea is similar...
The higher pitch HQ's are actually slower and more efficient. 7x4x3's are the most aggressive prop on SL drones.

No, Sir. in this case no saving happening, you just won't have stats updated for the flight you crashed.
