Castle BEC Update

Cool. Thanks for that Brian. I kind of figured that input voltage being so much higher than whats going out isn't going to be troubled too much by ripple currents but I can see what you are saying. The jest of it is it just gives the BEC a smoother voltage to work with. Right?

Anyway both versions work just fine in my applications. They are mainly all powering just a steering servo except one that is also powering 8 LED's as well. 4 of the older ones and 2 new version seem to work just fine.

Early on I was warned about using CC BEC. I was told to use Dimensions Engineering BEC instead because the CC switching BEC could possibly send full battery voltage to my servo/Rx in case of a failure. Well two years later they are all kicking butt. Also considering they are only $20 and so easy to adjust voltage output I will not use anything else. I will have to get the Pro version soon because for my XL. Hopefully it will also be trouble free as the smaller ones.
