| Cc bec ???
I have seen these little blue units labled "CC BEC" 10 amp peak. I see they limit the voltage. They say up to 25V in and 6 to 9V out. Where is this wired in, and why would you need one?? Thanks, LR |

you wire it into your servo. it gives power to your servo so you dont have to run a servo pack. if u need more info try searching

Yeah there was some threads in the electronics section, maybe it was a sticky, but it had great pics and diagrams.

A Battery Eliminator Circuit (BEC) is a little device that eliminates the need for a receiver and servo battery pack. It draws higher voltage from the motor batteries and drops it to a voltage level that is suitable for your receiver and servos. This is required in applications which draw high power for multiple servos or use more than 3S motor packs, as most ESCs with linear BECs are not designed to deliver enough V to power the high torque servo. You wire it directly in to your ESC's battery connector and then plug it into your receiver. Yes, you do need one....to be able to turn those wheels when crawling. Check this video out. JRH at Holmes Hobbies deminstates the power of the BEC http://www.youtube.com/watch?v=32SNV...&cat=13&page=1 | |

Ok, I think I understand this. But I have a 3cell lipo, do I still need one? Also I am running the new JR super high torque 403 in oz, and the Novak goat 18.5 turn brushless motor and esc combo. Wont my 3 cell lipo, provide 12.6 volts to my servo via my receiver? or will the receiver drop the voltage?? If I dot run one, will I burn anything up, or will I just not have enough power at the servo?? Thanks for your help. LR |

The ESC regulates the voltage; not the receiver. The battery plugs into the ESC and the ESC plugs into the receiver and supplies around 5 or 6V of power. The receiver then feeds the power to the servo. If you ran 12.6V straight into a receiver, it would blow up or at the very least, it wouldn't run for very long before blowing up. If you don't run the external BEC, you won't burn anything up, you just won't have enough juice, like you said, because the BEC circuit built into the ESC can't supply the amperage needed for those high torque servos. |

Ok, So I need one. The wiring looks simple enough. I just ordered one on line. Thanks LR Last edited by Little Rhody; 01-07-2009 at 01:56 PM. |
