I'm interested in using vesc with a very small drone motor. Haven't settled on a motor yet, but we're talking around 20A continuous max, probably on a 4s battery (14.8v).
The smallest VESC I have found so far is from Flipsky FSESC 4.12:
Now, compared to the standard drone ESC option:
Right now theres about a 10x size difference between the two. I realize the VESC is much more capable, but I suspect the size difference really comes from the additional current capacity I do not need.
I cannot settle with the BHELI_S, ESC, as it does not have functionality that I require (regen), as well as VESC has some very nice features I plan to take advantage of (Velocity control).
