hi,
good idea to add some more caps than usual. I have modded some chinese-plane-esc which I have used for my buggy conversion (the last two died because of water, but performed well...). I have at least doubled the capacaty of the caps, I changed the original ones by more and bigger caps. Size DOES matter
I just can say that the throttle is very smooth, and the esc doesn't get hot. Not even once it cogged. sure, brake's crap.
I have read a couple of times that more caps can help to keep the esc cool and prevent cogging; Schulze recommend for their esc to add caps in some cases.
Do you feel a difference now?
