Is that a big resistor or something? I'm not an electronics guy so i might be wrong:S
Oh and you cut a chunk of your cover! :L

Bart you are finally trying this? it is a cap and it stores from the battery and goes to the motor for quick off the line acceleration...

Bingo I'll update after the batts are charged. (if you look you can see the other mod that went along with this). I wrote a big article about this and decided to finally back up my own words.

You can make a circut based of BEAM Robotics pretty easily that builds up a large amount of power (10,000uF Cap should do it...), then dumps it, and cut's itself out, creating a straigh circut.

Well, I'm actually quite surprised...it worked better than I thought it would. I put a 6 cell on 2 of our xmods (mine and xmodkeiths) and quickly noticed that the top speed was dramatically improved but acceleration was not all that i was hoping for. This is easily explained as I increased overall voltage but did nothing really for current draw from the batteries. I used a 100 micro farad (uf) cap ($1.29) and soldered it directly to the ep (as I recommended in my sticky) where the battery wires connect. It's not a huge increase but it is most definitely noticeable...especially from a standstill. It definitely has more bottom end (and of course this in no way takes away from top speed). I do recommend that you be pretty proficient with a soldering iron before you try it and as always i will give more details if anyone is interested...maybe even a tut if this proves popular enough.

Interesting! This was something I kept asking about a few months ago and I think maybe what inspired to you write your sticky!
Now by luck I happen to have a very similar cap sitting next to me on my desk I think maybe I'll slap it on my Mustang on Monday!! Thanks!

Bart, you lost me...
So it increase low end torque, meaning it would do good in crawling? What do you think would happen if we strapped a 1000uF or 2000uF cap on there?

A capacitor in this situation is good for instantaneous power. The only way it would help in a crawler would be a burst of energy when going from a dead stop. I may put a bigger cap on later but the larger the cap the more current (this has nothing to do with voltage) there is instantly available and I have no idea what the limit is. Once you have taken off the cap does nothing so there is no sustained performance advantage...once my car is up too speed it is as if the cap is not there. It really can only help when taking off from a stop or when hitting the throttle after coasting or braking. I think it is much more suited for track use or general racing where you are on and off the throttle.

what if you ran your batteries to a board with the cap on it and then from the board to your ep??would this get storage then withdrawl

Absolutely (not sure why you would do this though). There would be very very minimal loss compared to my way. (a capacitor in this instance works best as close to the source of draw as possible). If I can come up with a schematic of the xmod ep i may find a way to put a cap even closer to the output side of the board (maybe right before the fets)

In this case they work just like a rechargeable battery with the difference being they hold a limited amount of energy with the benefit of being able to discharge said energy nearly instantaneously.

If JSHWAA's stuff wasn't deleted, I could give you schematics of the board, or atleast the Gen1 board. But it should be somewere, I swear I've seen Evo Skematics somewre.

The gains i could come up with from a schematic would only impress nerds (like me) who look at everything in life far deeper than need be. I doubt if it would be any better than what i did by putting the cap straight on the board. I know you, Liam, and B1g get this BUT FOR ANYONE ELSE... this is not adding to or replacing the caps on the motor!!! Doing so will guarantee a drop in performance. Certain members who used to post here alot are now preaching the motor cap crap on other sites. As with anything in life...do your own research.

It kinda hit me this morning.
The Evo servo motor only has two wires right? What about mounting the cap to help the servo with more torque, cause the stock evo servo is crap?
