    Anyone change the caps on a spectrum 120

    Looks like the caps are blown on mine purchased it used, the caps are bulged on the ends thought I might try replacing however they are not available by any numbers on them

    Those are ZLH series caps made by Rubycon, which are easy to find. You need a minimum voltage spec of 35V. Existing bank is 1170uf total, so I would probably use 500uf as a minimum on the replacements since this is a low current capacity ESC.

        Get more of them else you will blow them again.
        You had too much ripple which overheated the caps. Put 5 or 6 in parallel.
