What is a BEC

[Wheels2big]

I was wondering what a BEC was for and do you need one to have the big battery running the motor but a small pack just for the reciever?

It stands for Battery Elimination Circuit. What it does is allow you to run your receiver and servos off your "main" pack, without having to run a seperate receiver pack.

Generally, most all speed controls have this feature built-in. For crawlers, you'll ideally want to find one that can delever a good amount of amps to provide enough power to your servos.

You can also get seperate units (such as the Castle Creations BEC) that do the same thing.

in short

BEC stands for battery ellimination circuit. This circuit powers the servos and Rx. 3 amps of electricity can be diverted from the motor to power the servos when needed.

there are tons of threads about this exact subject

A lot of the electronics stuff is universal to RCs in general, so Google is a great source of info also.
