hi like i said #7 before.
just use 470uF/35V u-Low esr cap x 4(P) to soldered power-line.

it's will pretty cool esc, i am try long time.


By the way, something my experience,
you maybe need re-soldered quark power-line wire and motor line wire,
better need use PB-free solder with silver 6% or more and 220c temperatue up good solder.
it make sure your quark has hi-temp do not melt your junction.
this my experience..
hope this help.
