Sunrise Slim 20A ESC





These ESC's are just great.
- At the cost of a cheap ESC, you get a nice 20A ESC which weighs nothing but 5.5 grams without the wires.
- It has a very slim form factor which can easily fit inside the arms of most of the quadcopters for a very clean build.
- They also run Blheli, which is gaining popularity over SimonK as it has some really interesting features like Active Braking and OneShot.

Anyone tried flashing SimonK on this ESC ?

Or multishot?

Multishot doesn't work with Atmel ESCs.

So will it work on silabs ?
If yes which ones ?

I use Multishot on my Little Bee 20A (SiLabs F330). It works fine but F330 ESCs cannot go above 4kHz PID loop/ ESC update rate (and even that is a bit risky) and I only run 2kHz to be safe. At such low refresh rates there isn't really any need/ advantage of Multishot. I only flashed it for the cool startup tones and for any marginal advantage it may or may not have. F39x ESCs can go higher, up to 8kHz PID loop with Multishot (if your flight controller can take it). They can also go up to 32kHz ESC update rate if you unsync it from the PID loop (though the benefits of doing this are debateable).

Okay  thanks
that was quite info.
