Exclamation Rooster Crawler

Hey Guys,
If I am running a Rooster Crawler esc,
should I still be running a BEC as well seeing that the rooster apparently has an "internal BEC"?

I am using A
-Integy 35T motor
-Tower Pro Mg995 front servo
-Bluebird Hi Torque Rear servo
- and a micro servo for DIG
out of a spektrum AR600 RX

Thanks alot

Pretty much ALL ESC's have internal BEC's. This is where the RX gets power from (for about the last 25+ years).

For servo's under ~200inoz torque, you can likely use the ESC BEC.
Once over ~200inoz (or dual servos like you have) an external BEC is preferred. Most of us use the Castle Creations 10A BEC.
