This is the top result in my search. Love Greg’s videos. Worst video he has done. Doesn’t show cutting of the red wire. Doesn’t explain that the esc red wire should be cut because it’s only sending 6v to the receiver. Doesn’t explain that your rx needs 2 free ports. Doesn’t explain why you need to run both cables from the Bec to the rx. Didn’t need to show us a car. Should have shown us all the electronics on the table, what we need to do, and why. Sorry to be so critical, I know it’s hard to make videos. This clip raises more questions than answers and Greg can do better

I watched this hoping it would show how to wire the entire unit to include the other leads to the receiver

Maybe time to revisit this BEC as more servos go HV....just installed one in my EXB to boost my 45 kg AGF-RC servo from 7.4 to 8.4v😎

U really made sodering that wire so easy i been having a hard time sodering mine

A couple people mentioned the summit and using it for dual batteries. On the castle site there is a diagram on how to wire it with two batts. It is critical this is done correctly and the Internet searches lie. I am running it great on two summits using a Holmes hobby rx bypass adapter. It lets the BEC drive my high power servos off a y connector directly and continue using the BEC in the esc to drive the Rx and the shifting servos at safe 6 volts. So therefore my rigs are using 2 BEC's. It's sick. Do not plug the second connector off the castle BEC into the Rx as instructed "for best performance" it says. You do not need it to work and what's cool is it can be used as a power source for anything else. I use it for light bars.

Installing my castle bec and this video was a great help, thank you

Cool, I just got cc Bec 2.0 WP. One thing I read is that if your ESC has a internal BEC you have to disconnect the red wire from ESC.

Hi I have a question. Things I have Gen 7 pro receiver HW ESC model 1080 35kg servo that can work at 7.4 v My question is if the receiver wont burn if I set ESCs bec voltage to 7.4 and if the servo will take that voltage too

So you just plugged the wires into any random open port on the transmitter? And that actually works correctly? Mine says voltage/temp sensor port, RPM sensor port, and BATT/. So any of those would work?!?? What about for adding a switch for led lights too? Would it matter which ones you plugged them into? This is for a traxxas summit 1/10 if you're curious.

I run a mamba x with built in 8a peak bec. I installed a external castle 10a bec just cause. Over kill? Or a case of better safe than sorry? I can say that response and speed of my servo is faster so guess I answered my own question lol

I know this is an older video, but my receiver does not have a spare channel that I won't use to plug the three wire lead into. I can plug the two wire lead, but not the three wire lead. Will it still work?

What about the red wire on the esc does it still need to be removed like the earlier version

Hi im having a bit of trouble understand why we have a dual output? my reciever has two channels that accept a lead as a battery or power source should i just plug both into those? and why are there 2 so confused, I dont want to burn my reciever please help!!! love the vid by the way very informative.

I installed the castle creatiom bwc yesterday. Not this version, though. The previous one and it gets extremely hot when i plug in the battery. Any idea why?

another great video once again. I love your videos dude, they are the best.

How would you use this bec to power a servo without running the extra voltage through the receiver? The purpose of the extra set of output wires confuses me. Normally don’t bec just have 2 input wires and 2 or 3 output wires?

Great instructional video. 👍

Or.... pay just US$2 to buy a DC-to-DC switching buck converter and you can adjust that voltage with just a mini screwdriver and household multimeter. Forget about an expensive brand name BEC and its fancy schmancy adjuster dongle -- a BEC is just a fancy name for a common DC-to-DC buck converter so that they can charge you US$20 for a US$2 component. For FPV gear you might need some noise filtering, but for servos who cares.

Nice job Greg!

Why no video of the test run? if you say your gonna take it outside... Show us!

Thank you so much Greg.

hmmm, nice video I think this is a good idea on a few cars I have 👌👌

Why are there 2 wires that go into the receiver? Shouldnt one be enough?

Hi there... nice vid... Quick question: would you be able to do a vid installing the same BEC on traxxas summit 1/10? I just bought the same BEC for my traxxas summit 1/10... Thanks in advance...

I utilize this with a 3s LiPo battery in my Losi Pro Moto.

Can you use this on an xmaxx 8s?having voltage issues on my maxx, my futaba a700 servo is slow for some reason, and the fans keep on spinning slow and spinning fast

I have a holmes hobbies dual receiver bypass how do i hook this up im using the receiver bypass cause i burnt up a sr515 receiver cranking up my electronics to 7.4

I am considering running a BEC on my 2019 V4 Arma Kraton, the stock ESC (BLX185) currently outputs only 6 V. It does not have the option to adjust the internal BEC. So if I install the external BEC is that going to be overpowering my ESC or be bad for it? I currently have the Savox sw12g, which is capable of being powered by 7.4 V. And I’m pretty sure that the receiver I have in my car can handle it. Is it common for most receivers to be able to handle the increase up to 7.4 V? The other question though is in my going to increase the chance of overheating my ESC and my motor by pushing it be on the 6 V that its native for? Or should I just splurge another hundred bucks and simply pick up a new Mac 6 esc, Which has an adjustable be easy internally?

So I need a BEC for my servo. I'm not a hundred percent sure I understand the whole system of it. We are just bypassing the BEC in the ESC correct? So the external BEC just provides extra power to the receiver? And then the receiver transfers that extra power to the servo? I didn't notice you doing anything with the wires to the servo so I'm confused how it helps the servo.....

Question how would i wire this to a XMAXX 8s esc? Seeing as it has 2 battery connector

The led on the bec, is it in solid red when it's turned on? Does it mean that all is allright or not?

so it requires both of the rx type plugs to be plugged in? im confused, why does it have 2

I've been wanting to do this. Is an on/off switch beneficial at all? The bec would be powered on and servo or whichever parts are hooked up to it correct?

Your cool 😎 good job

great video! how do you program this BEC? and can it be program with the bluetooth CC link?

How do you install the Traxxas BEC onto a Traxxas Stampede?

Which wire connects to the servo

Ok I hooked up the bec cut the power from the esc But when there’s no load on the servo it twitches like crazy Anyone know what’s going on?

Whats that yellow CAR on the wall

Custom Setting increment for this B.E.C. is 7.2 jumping to 7.5 for the next selection. Missing the 7.4 volts that is so popular today for high voltage servo. That's why I'm giving it 3 star.

Hi, I've just installed the castle bec 2.0 WP on my Traxxas TRX4. But when all is connected the ESC led turn in fast blinking green, that means (according to the owner's manual) the ESC is not receiving a signal. I've already checked all connectors and is's OK. The led in ESC is in fast blinking green, the led on reciver in solid red and a small led on castle BEC is also in solid red... ¿faulty bec? ¿reprogram ESC? ¿any solutions? I don't know whats happening :( Please help. Thanks a lot.

is there a solution without the need for soldering?

Is it waterproof ?

How many channels do I need in my receiver to run this?

what if I have 2 batteries? Just connect to one of them.
