|  BEC or not...
This is my power package: MRC PRO Mongoose 1/18 Crawler Mini BL System 18.5T HS-645MG Blue Lipo 2-Cell 800mah 7.4v 2S1P 20C Battery I have everything but servo. (Servo on the way) Should I add A BEC? |

most would probably say yes, I am running my hitec 5645 directly off my 2s lipo without any problems thus far though. My servo isn't even high voltage but it really does not get that warm, sure I will smoke it at some point. My 2 cents.

Depending on your ESC & servo, ~200oz is about the max without a BEC before you run into issues. In general, other than "for fun" rigs/scalers, I say spring for an external BEC (unless you're running a BRXL ESC). |

Lots of people don't run a BEC with the Mongoose but I would always run a CC BEC as it's a few dollars of insurance for your ESC, has a small footprint, is light and programable - what's not to like?

Another thing to consider is most esc only deliver 5.5 to 5.8 volts to the servo. SO you lose just a bit of power. With the CC BEC you can set the output voltage. mine is set to 6.1 volts. My servo never gets warm and it is a 200 oz +/- (maybe 205 with voltage bump! oohhhhhh)

After reading the stickies and many many posts, I ended up going pretty vanilla, a hired servo and bec...I found both on amazon, but got the base plate elsewhere. As for wiring, there is a real easy to follow picture on the castle creations website....
