Where on the cap? If it is near a lead, that is the negative side. I have seen stripes with arrows, plain stripe, or a tiny mark on the round part.

You just touch the trigger and it is off like a shot. I need to find a way to improve traction.

Default They do help, BUT......

There is no one part we can bolt on our cars to make them superior. I don't care what magazine you read it in or how much you paid for it.


Caps help the speedo work with the battery. They do not give you a big kick in the butt when they discharge. They can make the speedo run cooler which turns in to lower resistance which means more power to the motor instead of being wasted as heat. Heat = resistance. As heat doubles, resistance goes up by the 4th power. I don't think they help on the high end at all, I also don't think they hurt. In the mid range from 1/4 to 1/2 throttle they help the ESC and battery get along with the on off cycles. I think the cap helps the battery work like it has lower internal resistance.

I use em.

Could anyone give me details (voltage rating, current rating, whatever else) that I need to ask for these "high frequency schottky diodes" that are being mentioned?

thanks guys.

As Root said, "There is no one part we can bolt on our cars to make them superior."
A combination of parts is what makes a car superior. On a Micro, add a 300 motor, KAN cells, lower the center of gravity, and a power cap. See my signature below for more details.

Hey guys,

Im about to install a Capacitor but I have seen a few different places to put them.

Where is the best place to add them? My ESC is the QP2.

I have seen some on the ESC and in the wires going tho the ESC.

The Cap goes on the battery wires going to the ESC. Be sure to get polarity right. It doesn't matter what ESC you have.

The Power Cap goes on the battery wires going to the ESC. I have included a picture.

Once again, be sure to get polarity right. There is usually a white stripe (or something similar) on the body of the capacitor. The wire near the stripe is the negative wire.
