You can find sources online - even shipping from across the world would be cheaper than the gas that a 2 hour trip will require; $40-60 in gas for $10 in parts.

Anyway, 25v caps are not good enough for 6s - peaked, 6s lipo is at 25.2v and you always want a little headroom. Besides, the back-EMF pulses may well exceed 25v when braking. 35v caps minimum for up to 6s. Don't know what that ESC is rated for, but the next step up for typical cap voltages will be 50v, which is good for 10s (although it won't hurt anything to use 50v caps even running only 4-6s - it just means physically larger caps).

As far as capacitance value goes, if the selection allows, it's better to go with a few smaller caps than one large one of the same total value (meaning 4x330uF = 1x1320uF). The extra surface area helps them shed heat better, and you also get better transient response. Of course, you pay for it in physical space needed and wiring hassles.

Thanks for your help Brian, I ordered a few up. I refuse to drive anywhere more than 30 minutes away lol Ive had the same tank of gas since the middle of May. Love the VW. My wife has a company car with a gas card but you cant do long(ish) trips they calculate the milage relatively accurately. Local runs are free though ! ID rather spend my money on RC than donate it to oil companies and government taxes. If anyone has some good pics of configurations to soldering up 4 caps link away, ive seen some nice ones here ill start digging, Thanks again.
