    Concerned regarding voltage drops due to using high power servos? While a power compensator is often called a glitch buster, what's actually happening is the current draw temporarily exceeds the capability of the power subsystem (typically the regulating circuit within an ECS called a BEC). When the BEC is overwhelmed, e.g. unable to supply adequate voltage to your servos, you experience a hesitation, what is referred to as a glitch because control is momentarily affected, or lost. And instead of arguing semantics, we just refer to our power compensator as a glitch buster, also!

    Fortunately, effecting a solution is pretty easy because simply paralleling a power capacitor into the power branch circuit serves to resolve the issue. Basically, it works by recharging when it's not needed and then discharging automatically to compensate for low voltage (referred to as amping or juicing up the voltage). This happens during periods of heavy current demand. Moreover, because it all happens in the background, e.g. requiring no user input or intervention, once you configure your system with our power compensator, you're done worrying about it because it'll just work silently and effectively from now on.

    Installation is quite simple because all you do is plug the lead into a spare port on your receiver (note; if they're full up, then just use a Y-harness to connect it along with any of the servos because doing this won't hurt a thing). Finally, Zip-tie the body of the glitch buster somewhere out of the way (where it won't foul a linkage, or otherwise adversely affect the mechanical or electronic subsystems).

    At last! Pilots and drivers justifiably concerned regarding electrical noise and glitches due to high power servos have a fantastic solution. If you're concerned about glitches, then you're well advised to use the glitch buster because it's cheap insurance against loss of control due to voltage draw-down.


    ProTip: if you're running extremely power hungry servos (after all, high torque doesn't appear like magic, it requires power - sometimes a lot of it) then if you're still getting glitches, either replace the existing ESC with a more capable unit, opt for an external aftermarket BEC, or merely add another power compensator to the circuit. Yes, you can run two or even three of them to serve as a buffer against the power demands of very strong control subsystems - like crawlers with unusually strong power requirements, or models running multiple steering servos.

    Better still, at this point consider switching away from a BEC altogether and use a separate battery for your control electronics. Severing the link between the propulsion battery, whose voltage fluctuates like crazy based on the demands you're putting on it with the drive motor, e.g. away from the power required for control-electronics, is just the best real solution because then you no longer subject the more delicate control-electronics to the back EMF pulse that flows through the system when you let off the throttle. Similarly, the receiver and servos won't ever again see the huge voltage spikes and draw-downs caused by the tremendous imbalance between propulsion demands vs. control demands. While this is a more sophisticated approach, we offer 2S LiPos in various capacities. best of all, a 2S LiPo is expensive (far less so than any BEC).
