I used to run a MM esc in an old conversion. I did like what was mentioned before run a computer fan to the side of it. Didn't temp. it but it did the job. It still runs I believe(sold it to a buddy.

I was thinking about the MMPro.. but I already have the MM, why not put it to good use? :)

BrianG, or any electronic wizard, or anyone who knows what kind of capacitor I need, can I use Mike's from RCM's store?
These?

Or could I go with the 2700uF and get better ratings, or could I go higher uF's, and get lower temps, I'm so lost right now..

Thing I worry about is your poor esav drivetrain. I don't think it'll like a beast of a motor spinning at almost 49k rpm...

It is better to use several smaller uF caps in parallel, rather than one large cap- better heat dissipation and responce time to voltage spikes.

That said, a total uF value of about ~5000 shouldnt be exceded, lest you poop yourself at the giant sparks that also eat away at your battery & esc plugs...

Solder them in parallel to the esc's battery wires, + leg of the cap to + wire, and - to -, close to the esc as possible (strip some insulation away with an exacto blade etc).

You've lost me, as I'm an idiot, how many and what uF caps would you recommend?

And a diagram of the drawing? Sorry, I'm a retard..

As far as the ESav's drivetrain, I was thinking about switching the ESav arms for the Sav X arms, as well as the dogbones, this will be a time consuming project, about a couple hours, with money I don't have.....yet

Thanks guys for the help so far!

The single hvmaxx type cap would work fine, but a couple of those ones mike sells (in your link) would be better.

Im at work so cant do a diagram, and havent got any of my IE favourites to reference, but hopefully someone will help you with that or a photo.

Neil: love the new avatar. It looks like something from the movie "Watchmen"

rawfuls · 08.07.2009, 11:49 AM

I will try out the one or multiple, once I get a diagram :)

MS Paint to the rescue.

If you had two caps, you'd just twist the + legs together then solder to the power wire, same deal with the - legs. You will ofcourse have to insulate any bare wire or cap leads to prevent a short; keep any fly leads short as possible and mount the cap to the esc case with some doubled sided sticky pads etc.
