I could use an answer to this question too.. Please help.

If glitching isn't caused by a voltage drop, you can also try winding the throttle cable around a ferrite ring/donut as close to the ESC as possible. Caps will filter noise and shore up the 5/6v rail, but does nothing for noise on the throttle line. The ferrite ring will help with that. Just depends what the source of the glitch is...

When choosing a capacitor for a 14.8v setup, do I choose one that has a higher Voltage or one that has a higher uF?

[Joe Ford]

The one used by Spektrum is a 10v 4700µF low ESR aluminum electrolytic capacitor. Part # SPM1600 if you want to buy it direct...$6 with the rx lead already on it.

So I do not need a cap with a higher voltage when I'm on 14.8v? 10v is enough?

10v is fine because the cap is only dealing with the voltage on the receiver; which is anywhere between 4.8-6.0 volts on most setups. So the input voltage won't have any effect on the receiver or capacitor voltage.

sorry to bring back an old topic, but I figure better than starting a new one?

Anyway, here is what I am experiencing:

At the race recently I decided to put more power into my vehicles while still running my trusty Novak Havoc ESCs. I went from a Novak Ballistic 13.5 to a 8.5 for both 2wd 1/10 buggy and 2wd SCT.

The power was right on just like how I like, but I had some instances of what I would describe as a brown out. during the runs, it seemed as if all of a sudden I lost power to the motor, then it would come on again and be fine. Servo steering was fine.

This would happen about midway in the race. I was advised by others they have experienced this too. Adding to this, at some point someone yelled to the marshalls to turn the car off then on to "reset" the esc as they had experienced this before with there havoc usage.

Temps on the motor and ESC were 150s & 130s respectively.

I am using high power servos, which makes me wonder if I need a glitch buster cap?

Any ideas?
