First answer this question.

1. Do you have a radio contolled rock crawler?

Yes, then you need a BEC.
No, click the X at the top right of your screen.

I know your cousins brothers friend said you did not need one, but you do.

I know you don't run your car hard, but you still need one.

I know you have the newest baddest most awesome esc ever, but you still need a BEC. (Maybe the new Holmes Hobby ESC will change this, but for now 99.9% of you this still applies.)

In the end the fact remains.

YES YOU NEED A BEC. YES YOU NEED A BEC. YES YOU NEED A BEC. YES YOU NEED A BEC.
YES YOU NEED A BEC. YES YOU NEED A BEC. YES YOU NEED A BEC. YES YOU NEED A BEC.
YES YOU NEED A BEC. YES YOU NEED A BEC. YES YOU NEED A BEC. YES YOU NEED A BEC.
YES YOU NEED A BEC. YES YOU NEED A BEC. YES YOU NEED A BEC. YES YOU NEED A BEC.

What about an ESC? Do I need one of these? I keep reading about them, but am unsure.

Rockcrawler · 11-17-2009, 05:43 PM

I would have agreed with this a few months ago........but now JRH's new ESC does not need a BEC.

X2 mine is running strong on 3s with two motors and a big servo

Ripperfi · 11-17-2009, 06:19 PM

Sooooo what your telling me is, I need a BEC? Did I get that right? But what if I drive a bone stock MRC with stock servo. I mean, its a crawler right so I answer yes to your question. Do I still need a BEC?

Lil Jon · 11-17-2009, 06:31 PM

But Ted i dont think my rc tomato crawler needs a bec.

HomerJ · 11-17-2009, 07:16 PM

Can we get this stickied please???

romulus22 · 11-17-2009, 08:42 PM

what is a BEC and do i need one on my scaler

custumrig · 11-17-2009, 08:46 PM

do I need a BEC in my rtc axial ax10? and why not use 4 double aa's

rmdesignworks · 11-17-2009, 08:52 PM

i guess this means i cant compete this weekend seeing as how the only thing that has fried on my rig IS the CC bec

JeepinDoug · 11-17-2009, 08:59 PM

Bose-Einstein condensation
My rig will never get that cold!

Sharkey · 11-17-2009, 11:59 PM

ill disagree. not all trucks need a bec, it depends on what your setup is and how you use it. i have an lrp quantum super reverse (its designed for a touring car or 1/10 scale 2wd truck) that has a 1 amp internal bec, i run 6 cell nimh and a hitec 645mg, and i dont need a bec, ive never had an issue with that setup. i now have rear steer with a 2nd 645 on the rear axle, and once, and only once have i had an issue with the esc momentarely shutting down, and thats because i had both front and rear servos stalled out for a few seconds, once i let off the rear steer it was no problem.

i will agree that when running power hungry high torque digital servos that most esc's wont provide the current needed to power steering and a dig/rear steer servo, a bec will take care of the issues.

you need a BEC

picklewagon · 11-18-2009, 12:11 AM

Through recent emails with Novak Tech support, my mongoose in my MRC does not need a BEC even with a full size Airtronics rock crusher. And I too have no X in the top right of my screen.

dboy1k · 11-18-2009, 12:14 AM

so you say you dont need one then why do you have 1

Thank you for proving my point. You have never had any problems, oh wait, yes you have. And guess what. With an external BEC, you would not have had that problem you never had, oh wait yes you did. PLEASE SEE THE FIRST POST FOR SOME GREAT ADVICE.

OK. but when you smoke your ESC or burn upyour servo you will be on here bitching that you have no idea why your electronics died. And I will say

"You should have ran a BEC".

So it sounds like you definitely need a BEC.

I can't help you on that one. I suggest a hammer to the screen.

Sharkey · 11-18-2009, 12:49 AM

i had 2 servos stalled completely, i was inbetween rocks and couldnt turn and was trying to. how would a bec change that??? all it would have done is held the servos at stall point till i baked them or the pack went flat. never had a problem since that one time, and why, cause i dont stall both servos out, i learned what i cant do.

telling everyone that they must have a bec is complete bs. not everyone needs a bec, like i said, depends on the truck. i know plenty of people that dont run them and have no issue whatsoever. yes there is a place for them, and for comps your going to want to have one, however the average setup with an average servo and esc will be alright without it.
