Since it's somewhat related, I guess I could post here rather than make a new thread...
My Novak Havoc SC Pro blew its capacitor because of an engine failure (and resulting user failure, doh). The stock one seems to be 5600uF/10V. Of course with Novak being out of business nowadays there's no direct replacement, and all the ones available at my local RC shop seem to be waaaay lower in uF rating and/or different voltage, and I'm not sure if they'd fit the bill so to speak.
The Havoc was in my SC10 4x4, but I bought a new combo for that and rather than scrap or sell the Havoc I am thinking of doing some other switcharounds with my cars, and maybe put this Havoc on my 2wd SC10 - on the 4x4 it started cutting off throttle way too soon even with plenty of voltage left (possibly the cap might've been already failing and causing that in part though?), but with the 2wd it'd be driving a Speed Passion 540 7.5t / 5100kv motor rather than the Havok Kinetic 550 4.5t 4700kv which is now in pieces and I don't have the knowhow to repair it even if possible. At any rate the stress on the ESC should be way lower with the 2wd setup, so I guess a weaker cap might be enough? I suppose I could alternatively search electronics stores for more similar replacements.
