Would this work for the silabs version of Hobbywing 25A?

I'm wondering if this will fix my unstable hobbywing esc issues.

it depends on what the FET layout is. im GUESSING that they are the same(probably a copy?) so its worth a try. sacrificing one ESC to test wouldn't be so bad if you had an extra.

I have 4 of them going spare as I can't use them for multirotor at the moment.
Might give the arduino method a try.

Yeah that should work. to get the best results you need to copy the 6A plush code and chanege the NFET/PFET delay time to the fets on the esc so the fet on/off timing is the best. Then compile it into a new hex. I'll write a quick guide soon.

I did one HW funfly 10a tonight using the Turnigy 6A multirotor hex. so far it seems OK, The motor (suppo 2214) starts and runs fine but I still don't have a very linear throttle. Once you hit about 3/4 stick using a mutli advance stock setting of 1.0 its like hitting Turbo... the motor is smooth up to 3/4 throttle then JUMPS to full and you have no throttle control past 3/4 stick. If i back off the multi advance to .75 the throttle is more linear BUT once you hit 3/4 stick thats it...motor never reaches full power

I think I'll flash 3 more and try them on a quad...I do think the firmware still needs some more work by someone smarter than me

more info here, /i'm grabing the new files and trying them out.

That's because the throttle range is set to 1150(activate
esc), 1200(start motor), and 1800(max throttle). In mwc I set min_command to 1140, min_throttle to 1195, and max_throttle to 1850. works fine. The issue at 3/4 you describe is probably because your throttle range is 1000 to 2000?

Just want to confirm that was able to flash 4 x Plush 25A successfully. Tested with Arcucopter 2.7 & APM2.0.

Start is a bit tricky. Once 1 motor did not start, otherwise motors need to be tricked to start. Once going it works fine.

In my opinion battery consumption is higher that with stock Escs.

Rev 6 flashed.

ah good rev6 works. Use the 25a hex I posted here and that will fix the startup issues.

Is the firmwares found here the latest and optimized for multicopter use if I choose firmware with MULTI in its name?

I've got 3 Plush 25 amp ESC's with Atmel processors and 1 Plush 25 amp ESC with Silab processor (lucky me ).

Now that the Silabs can also be flashed with Multicopter firmware I might give it a go. However I don't really feel like buying a 25 dollar toolstick to flash a 12 dollar ESC. Do you think it will ever be possible to flash it using the USBASP controller. Almost everybody with a KK board already has this programmer. Or is this strictly for Atmel?
