Excellent ESC's!

Jan 12, 2018

I have been using these ESC's for the last 6 months with an accumulation of 70 flights. They have stood the test of many very hard crashes without a hint of problems. I would buy more but these are still going strong! Most definitely recommend them!

Great little esc, fits nicely in my 16mm arms. I was a little concerned about cooling with it inside the arms, but it was never an issue. Although the esc board is rated for 30a and the wires limit the esc to 20a, I would not recommend exceeding 20a per esc especially if you are running the esc in the arms. I was easily able to flash this with the afro flash tool, and found that running BLHeli ran the motors smoother than SimonK. Overall this is a great light weight solution and allows for clean wiring. Note that the esc is very slim and long so make sure your arms are long enough if you plan to run internally.

I've purchased the "Afro" brand ESC's in the past and was a little worried about this "smaller" one. It's nice and small and just plain "works" with no issues. I was worried about the 20awg wiring so I "upgraded" it to 18awg and upgraded the firmware to the latest version and so far I have had no issues. The "Afro" brand of ESC's are the only ones I'll buy.

30A ESC in the size and disguise of a 20A ESC. Great for pushing the limits. One star less for quality because out of 6 one was shorted-out but price-wise still can't complain, just buy some spares.

If you use Pixhawk/HKPilot32 then make sure you set RC_SPEED to 250 (the maximum PWM frequency of which the 1KHz ESC speed is divisible) to avoid stuttering/sync issues and latest SimonK firmware!

Shame there is not more documentation about the I2C functionality because native 1KHz control frequency would be ideal and some flight controllers support that. Pixhawk too but that also lacks documentation. Anyway, it works well on Pixhawk with the right settings and firmware.
