there are also
* sapog: https://docs.zubax.com/sapog, https://github.com/PX4/sapog
* VESC: http://vedder.se/2015/01/vesc-open-source-esc/, https://github.com/vedderb/bldc
these are IMHO even advanced since they use FOC, nothing I have heard here so far
it's not like there wouldn't be options to contribute

So it only checks on upgrades, that is perfect and about as unobtrusive as it gets. I was going off your earlier statement that BLHeli suite would always need an internet connection and assumed that meant to even change settings at the field we would need a connection.

Will definately pick up some of the myairbots escs, I have been using their bumpbees/super racer bees and they work great.

Good idea , thanks for the link. I don't think all the fuss is just about code contribution. That's only a small part of an open source community. I think thousands of people have cumulatively commited thousands of hours of support and feedback via forums and github to make blheli what it is today.

at a minimum i would think blheli_32 should use bipolar complementary pwm, but it seems they're still only pwming one side

Some BLHeli_32 escs will have current limiting support in hardware, some will not. But it can always be disabled. Limiting current can maybe help protect against toasting escs, but it will reduce the BLHeli "snappiness". So of course it can be disabled .

7bpm asked previously about the max burst amp rating on the 35A and 50A wraith. I'm curious about this also. I'm about ready to make 2 builds. Would it be safe to pair the 35A version with motors like the new F40 Pro 2400kv and the Cobra CE 2207 2600kv? According to mini quad test bench they can draw up to 40-44 amps on at 100% load. I wouldn't push them too hard, but sometimes I like letting loose if it's clear fields.

Just curious what are your thoughts pairing the 35A wraiths with these newer motors? Also what protocol would be used as default? Will the dshot 1200 be available for these ESC as soon as they are released? I just ordered 8pcs of your new ESC. Looking forward to trying them out.

Don't worry your batteries will die way sooner than the escs burn.

I can't answer for the amps rating of the Wraith ESCs, Airbot can comment on that.

But as for Dshot, once a code is released, it supports fast Dshot, at least up to Dshot1200, which has been tested.
As for now, we are in a limited distribution phase where we want to test the code as much as possible before we go to a full release.

The name "racerstar" usually speaks for itself Most is rebranded low end stuff.

In this case perhaps, but my Racerstar 30a V2's have gone through more abuse than my LittleBee's or even DYS ESC's could handle. It really depends on the model with them.. sometimes they hit a homerun.

My question is how is this possible though? Is it? Hmm

"Racerstar Racer33 33A 2-4S Beheli_S 32bit"

Its running BeHeli! I wonder if that's like BLheli?

As of now, it is scam. Because there is no BLHeli_32 code released yet. But also they are not yet available.
So maybe it will be legit and available once code is released.

Sounds like you don't want to disclose something
