It's been a while since I built a quad, so I'm not up to date on the new advances, specifically in ESCs.
I'm planning a build of a new quad, probably on a Tarot Mini 250 frame. I have some motors and ESCs that I think I bought for it. They are Emax 12A SimonK ESCs, and Emax mt1806-2280kv motors. I don't know about the quality of the motors, but I think the specs are good for this quad. The question I have is about the ESCs.
Obviously, the ESCs come with SimonK firmware, which is good, but it looks like they now support BLHelli. In the past I used to flash BLHelli firmware to stock ESCs and was happy with it, but since these already have SimonK, it might not be necessary.
The one thing I noticed about the BLHelli firmware is something called oneshot. Does LibraPilot support oneshot? Is there any other advantage to reflashing them?

You should use "Oneshot125" with BLHeli and "PWMSyncr" using Simonk.
BLHeli can also do active braking and should allow PID 10/15% higher compared to PWMSyncr.
PWMSyncr/Simonk still a good choice :)

Thanks. I think I'll go ahead and update to BLHeli. It looks like they're latest ESCs are running BLHeli, and I hate to start on an old firmware! :D

Old thread, but a bit of a warning...
I bought some SimonK ESCs (eBay) and they had an old version of SimonK that just didn't run right.
I upgraded them to the latest SimonK and they straightened out and work fine.
-
The latest SimonK fw should support oneshot also.
I have the emax blheli 12A esc but i sort them out, the SimonK is the same hardware, the ones i have a very bad soldered, i had to rework the upper side with the fets completely... So be aware pushing them hard can cause desoldering...
-
Don't confuse SimonK with SimonSeries. The Emax 12A ESCs run on Silabs chips, which SimonK doesn't support. Emax used the name SimonSeries to lure in customers, a typical marketing strategy in the far east.

New version of the Emax ESC's manual says that these ESCs are BLHeli based. The new version do OneShot125, I am flying my Nighthawk with these ESCs and OneShot.

I have these Emax 12a Esc on my 250 with mt2204 Motors, i flashed the escs with Blheli 14, i see there is damped light mode availible up too version 11.2! i used xp12a code
can somebodey post the settings in for use with active braking! i am unsure how must setting the Blheli for the mt2204 Motors

Standard settings are Demag=Low, PWM Frequency/Damped=Low, Motor Timing=Medium
Start there and then you can change things if you have a problem later.
