Good caps aren't small in size, they need some mass to handle the heat. Some of these little dinky caps they are installing in these ESC's are a joke!
It's not necessary to replace, putting good ones in parallel will bolster them up. I buy my caps from Mouser, spent a lot of time researching specs.. If anyone is interested in some part numbers, just let me know...
