Picked up a new perfex ka-15l esc off ebay but didnt come with any setup instructions. Anyone know where I can find some. Thanks

I'm not familar with that esc, but if you know which RCs Kyosho puts it in, then you should be able to find what you're lookinmg for in manual for any Kyosho RC that uses that esc -
