Super Capacitors Module
http://www.hobbypartz.com/escca.html
What exactly will this do for me? I am more than happy with the performance of my Xerun ESC, but if theres a benefit for running these as such a low cost I might wanna try it out. Could I use it with other ESCs? |
Back when lipos were not as high of a C rating as they are now, ripple current was a prob for escs - caps were added to help esc deal with ripple current. I was running a Quark 125b back then and added caps to the power wires right at the board before I ever run it - it was a common mod.
It also is supposed to lower esc temps. Now, these caps seem more intended more to dampen voltage spikes that cause rcvr brown outs than to help the esc. I run one in my Emaxx and am not real sure it makes a lot of diff. |

Thanks alot guys! I think its worth the small cost.

Keep in mind that those caps are only rated for 16V. So it's fine for using with a 1/10 ESC on 2-3S, but for a 1/8 ESC on 4-6S you will need caps rated for higher voltage.
You need to have a little overhead in the voltage the caps are rated for compared to the voltage the ESC is rated for. So if the ESC is max 4S use 25V caps, if the ESC is max 6S use 35V caps. You can run 25V caps on a 6S max ESC, but only if you are 100% sure you'll only be running 4S lipos with it. It just makes more sense to use 35V caps in case you ever decide to try a 5-6S lipo. The reason for this is because running caps close to or at their max rated voltage can significantly reduce their lifespan, and increase the likelihood of failure. I see in your signature you have the Xerun ESC in an E-maxx, so even if you are using 4S that cap bank you linked isn't rated high enough. |
We have TransCap modules for different number of cells:
TeamNovak TC modules You can always use a module designed for more cells---3S module for 2S racing, 4S-6S module for 3S, etc. But not the other way around---no 2S module, when using 3S lipos. These modules can be used on any brand esc---brush or brushless---that require externally mounted caps. They may also be used on escs with the caps soldered onto the PCBs---for these, we recommend complete removal of the existing (burnt) caps before installing these external modules. The capacitor wires should also be removed from the PCBs, taking care not to damage the traces. |
Novak Two,
I have a Novak glitch buster cap that is rated at 5600 uFareds plugged into my Spektrum SR300 rx, which solved a Savox servo glitching problem I had. These trans caps of yours solve a different problem I take it, one gererated by the motor draw on the battery? The higher the C rating of LiPo 2s batteries, the less likely I am to need or benefit from these? A 40C or 50C battery will cause less "ripple currents" than a 25C battery? If this is so, does this mean that a higher C rated battery is easier on an esc and/or better for an esc? (assuming the esc is rated at 80+ amps or so) |
i'm not using any capacitor with my xerun 150A esc... and i'm not having glitch or brown outs with my sanwa 451r rx with a 7955TG servo... never had a problem even before with a spektrum rx...

This is a question for engineering/tech support ([email protected]); you are correct that the GlitchBuster and the TransCap module are two separate capacitors designed for separate jobs. Every esc we make includes the TC module installed:
The Glitch Buster Capacitor is Novak’s weapon in the war against glitching. The same technology that professional racers around the world have been using to fight glitching problems is now available for everyone. The Glitch Buster works by storing power from the BEC, and acting as a filter to eliminate any noises generated by servos that can wreak havoc on your radio system. Another benefit of using Novak’s Glitch Buster is that it reduces the load on the ESC’s BEC, and improves response time, which makes the servo faster! The high-capacity, super low-resistance capacitor comes pre-wired and ready to install into any standard receiver. Simply plug it directly into any open channel or battery slot on the receiver, and experience a glitch-free ride. The Glitch Buster is also recommended to use with 2.4GHz radio systems, ensuring trouble-free operation by working to prevent radio drop outs.

I have a xerun hobbywing esc, where do I solder the super capacitors at?
