ESC sync issues with SimonK?

Category : RC

I remember back some time when SimonK had some sync issues with some NTM motors, but that got sorted out quickly by Simon. So I have not really thought much about it till recently when I was going to build me a small fpv quad.

It seems like high pole count motors are especially prone to develop sync issues. This caught my attention since my new quad are going to use some 2204 size sunnyskys with 16 pole count, which is considered a high count (some say more than 12 is). So I dug around the forums and found this thread which several users are experiencing everything from sync issues to burnt motors.

bickie @ rcgroups: I noticed when running this motor it stutters when running (all other motors are fine on the same ESCs – HK F10A + SimonK)

It seems like several user are experiencing the same problems using the Hobbyking F10 esc and simonk. After some more reading it become quite clear it isn’t the ESC itself, but the firmware. The bottom line is to change to BLHeli, so it seems for now. Since it’s most likely a firmware issue I guess it isn’t long time until Simon fixes it. BLHeli also supports the popular Afro ESC series from hobbyking now!

sskaug the developer of BLHeli wrote this great article explaining the sync issues! Read it. You might also be interested in my guide for flashing BLHeli. It’s the same principle for all ESCs except you need to change to the corresponding .hex file.

If you’re not into flashing there is a alternative, the Hobbywing Platinum series. They are special designed for multirotor use, might be worth checking out if it seems interesting.
