Axial SCX10 Deadbolt - Castle BEC - $50 Budget Build - Week 12

[@kkhalifah1019]

Having built drones before, I used to use a fully adjustable DC-DC regulator (which is exactly what 'programmable' BECs are) that barely costs US$1-2 to supply power to my FPV electronics on a separate circuit. Once wired in a similar fashion, it's a simple matter of using a multimeter and a mini screwdriver to dial down the output to anything from 6v to 7.4v or any other voltage to suit whatever gear you have (in your case a servo). They will happily pump out up to a whopping 5 amps all day. Adjustable regulators are the same size as the BEC you have there and wire up exactly the same way, but are waaaaaay cheaper than your fancy 'programmable' ones....

[@roethle]

If you don't want to remove the wire from your ESC you can get a servo extender for a few cents and remove the wire on that. Also makes accessing castle link much easier if the extender runs outside of the receiver box.

[@RCCrawlerWorkbench]

You did a fantastic job explaining the bec functions and methods of use. People should have no problems following those simple instructions. I getting ready to install one as well ant though about doing a step by step installation video as well. Thumbsup

[@scottfirman]

I use a furrus ring as well. Your BEC usually comes with with one. If not, they are cheap enough or you may even be able to steal one out of an old floresecent twist bulb. Just disassemble and cut out the metal ring that has wire wrapped around it. You then take your extended wire from your BEC and wrap it several times around the Ring. It eliminates stray signals from the ESC and prevents servo jitter. I have a bad case of it in my airboat right now. I bought a handful of BEC's from H. K. ( turnigy) a while back for cheap.

[@SendItRC]

Just wanted to say that while I am not new to RC, I am new to crawling and trail running. I just built a Wraith (see profile pic...LOL) with a high torque digital servo and a Sidewinder 3 ESC and sure enough....I need the BEC. This video made everything CRYSTAL clear...so many thanks!

[@erikm2003]

I’m making a v plow for my traxxas trx4 sport. I want to get a bec. I’m running the stock xl5 and 3 20kg amazon servos (2 for plow and 1 for steering) and I am also using a 2075 servo winch for it to raise and lower. How would you recommend hooking up a bec. Thanks I hope this isn’t confusing.

[@jamurphy8386]

*THANK YOU!!!* I've actually been in the Hobby longer than you have...... Yet, what I knew about BECs could fit on the head of a pin!! 😲😲 I understood that they work something like a sophisticated capacitor, in that it provides dedicated power to the Servo. For the FIRST time, I actually understand why I need one of these, instead of a "Glitch Buster"(Capacitor Circuit). I've received SO many *BS* explanations of what a BEC does - it would even confuse YOU! I'm going to link this video every time someone asks me about using a BEC. Murph

[@toddwanke602]

Thanks for all the info. I bought a beefy servo, and am taking on a BEC project for the first time on similar Wraith 1.9.

[@igorg9538]

thx a ton, very clean explanation. I dont own the bypass and did the passing by the receiver connection. Is it better to have the bypass installed?. I have a fusion 1800 with a flysky receiver (6channels) and the castle link BEC. If I undrestand correctly by not using the bypass the esc is not feeding any lower to the receiver therefore will not heatup?

[@jacobhendrickson8935]

Your very good at making these things as clear and easy to understand as possible. Enough so where anyone that could not follow clearly from this would need a bit of hands on help to learn. I had always stuck with 2 s so was happy with my stock ESC's BEC until lately I have over to 3s also and using 2200 packs as well. I've went with switching becs in my scalers now as well

[@OldeSchoolRcUk]

Perfect cleared up re direct servo running with exclusion of the white control Lead if I’m running direct the one on the bec stays blank I assume

[@bizlaforest]

Ty. Great vid. 40 vids on how this goes down...all failed but you nailed it in first few min and i actually feel educated about this topic now. Now time to go install my new toy. Cheers🍻

[@grvtyboyRC]

Thanks for this info. It was the most descriptive explanation for directly wiring the BEC to the servo (using the holmes bypass connector) thanks. Exactly what I want to do.

[@brianhilligoss]

Don't forget if powering a spectrum rx from the bind port to remove the yellow/orange wire from the bec. It's ground referenced and will set the rx to bind mode every time you power it on.

[@HarleyDesignsInc]

Great info, since I am not a Spectrum user I wouldn't have caught that. I will add that to the text.

[@SLACKTIDECREW]

Hello, i just got a deadbolt for Christmas been running a nimh and have had no problems. Bought a lipo 2s today when I plugged it in everything was unresponsive and was almost as if I was having radio interference... do you think this could be from not having a bec?

[@ImranKhan-xd1zm]

wow such a nice video brother go ahead make more videos electronic types brother I have a question I got a new rc 800 B412 helicopter. and they give me one motor and castle creation 20A BEC pro and reciver and Bavarian DEMON 3X FLYBARLESS system so how I connect these kindly tell me I will be appreciate. thank you

[@jacobhendrickson8935]

Lately I have considered eliminating my use of becs being how well the LiFe packs work as a receiver pack in my nitros even the 700mAh zippy LiFe 2s 6.6v receiver pack runs 3 digital high torque tank after tank in my Revo 3.3. And these packs are feather light. Also come in 1100mah version for a bit of extra runtime and amperage. I love them and figure the 700mAh version on a single servo scaler would last really long.

[@HarleyDesignsInc]

Jacob Hendrickson I don't see a reason to run a second battery. It's something else you would have to charge, it adds a lot of extra weight and becomes a packaging issue vs the tiny little BEC. There is a reason that BEC's are so popular.

[@AlphaPhaseSleep]

Ext BEC should be connected to Bind/Batt slot on reciever ;)

[@gotface1403]

I know this is 7 years old. But any chance you got a new link for the adapter you use to direct power the servo? Your link doesn't work anymore.

[@Muslim-ik]

hello Harley I just want to know I found a bec from chain less than 3 dollars is it ok to use it or go for the expensive one is there any different

[@MrJohnson0605]

Question sir, I have a Traxxas Summit and it has 2 steering servo's. How do i use the BEC to power the steering servo's and still be plugged into the ESC?

[@feliciano1358]

Awsome vid. It actually make's it easier to understand how a BEC should work effectively. I did not know about the Holm hobbies bypass. I would assume that the bypass makes the system work's a little more effectively because it is a in line hook up.atleast that is what I assume.

[@HarleyDesignsInc]

Correct, it puts the power directly to the servo.

[@ShawnTheSilentLurkerKerr]

Lot of great info in this one. Thumbs up for sure. Not that I don't thumbs up all of them (which I do) Already got the Castle Link as well as the BEC, but was wondering what ESCs, other than Castle Creation ESCs, work with the Castle Link.

[@HarleyDesignsInc]

Shawn, only ESC's made by castle work with the castle link. Such as some of the Axial ESC's as well as Holmes Hobbies. Holmes has castle build his ESC to the specs and programming he asks for.

[@supaxui]

is it possible for the bec to burn out the receiver if the output voltage of bec is beyond the limitation of the receiver? and will there be any damage if I over kill on the bec say if i use a 20amp bec for just one servo?

[@joelgreer2552]

If I get a Hi-Tec High Voltage Servo that can handle 7.4V and I'm only running 2S, can I just cut the power (red) wire from the ESC to eliminate the internal BEC and run the servo off the full battery power?

[@HarleyDesignsInc]

No, because a fully charged 2s Lipo is 8.4v and then as it dies it will get down to as low as 6.0v.

[@thatsmyrc]

this was a awesome explanation.. I use just the reciever as my esc for my rc conversion rigs that only use servo gear drives.. IF i was too want too add a bec to increase voltage too a few servos (Not all) channels whats the correct format? bec to direct battery then a y adaptor to that channel or? reason asking is a few of my linear servos run on 6v then reg brushed servos running 360 as gear drives I'd like to run max at 6.8v thanks again harley 8-)

[@anthny6912]

What receiver do you recommend. I am looking for one that has no long antenna like on a traxxas receiver.

[@chess135]

thees days was some high quallity vids. awesome.

[@HarleyDesignsInc]

Haha, yeah these were definitely something different 😁

[@Razor61969]

Love your vids. Everytime I'm about to do something I come here first for tips haha. Great info and very easy to follow.

[@hardcoretam]

Is it possibly to use the AE2 ESC on 3s with the BEC only powering the servo via a bypass adaptor? I have an AE2 and i want to run it on 3s but i also want to be able to easily connect it to the Castle Link if i need to

[@igorg9538]

Hey bud quick qiestuin. I had a previous setup where I plugged BEC servo and ESC i to the receiver. I did remove the center wire same way you did. Later on I chamged ESC and bought a Y splitter so I connected the servo and BEC i to the the Y amd then to the receiver. The thing is that I left the center wire coming from the esc still out. Should I put it back into the plug?

[@HarleyDesignsInc]

Did you buy a Y splitter or a bypass adapter? They are very different things.

[@igorg9538]

@@HarleyDesignsInc a Y splitter

[@rafa37523]

Hey Bud, I bought on sale a RC4WD BEC, on one end it only have 2 wires (+ - ) and not 3 wires like this CC BEC, Is the Wiring the same as this one, or do I hve to keep all 3 wires from the ESC? ty

[@HarleyDesignsInc]

Rafa Rcchannel From the ESC? What? If it only has 2 wires then they are only power and ground, so everything still like I posted.

[@purrungas2012]

excellent. thank you, do these BECs come with specific voltage regulators? my receiver has a 6v maximum but I want to switch my NI CAD pack to a LIPO at least 7.4 v...and maybe 3000 mili amp....is it doable? thanks again

[@HarleyDesignsInc]

+purrungas2012 you plug them into the Castle Link (sold seperately)nand connect it to your PC to adjust the voltage output.

[@rogerbeam3364]

So if I use a receiver bypass adapter with my sbec (Turnigy) I can leave the power wire in place going into the receiver so I can use my lights ? ... my question might sound off but I just woke up .

[@HarleyDesignsInc]

Yes you could do that.

[@channotpoling20]

If I use the Holmes adapter, what do I do with the two wires (red/black)?

[@jeepsterc104]

Harley im using novak 5a bec and it came with a switch.I have to turn on this switch to power my servo. So with that castle bec, is it applicable to solder a switch and allows your battery left plugged without draining it? Was that advisable?

[@HarleyDesignsInc]

Even then, I would always advise you to unplug your lipo. Even an ESC that is turned off can bleed power slowly and kill your lipo.

[@ShawnTheSilentLurkerKerr]

LiPo or not, always unplug the battery. There is no need to supply power to a truck that is just sitting.

[@xjcrawler99]

Awesome video as always. Do you recommend a high torque or fast servo. And what's the best servo on the cheaper side. thanks

[@ShawnTheSilentLurkerKerr]

Depends on what you are doing with the servo. I am looking at the CYS S2220 for my Twin Hammers. But I don't know anyone who has experience with that brand. www.servodatabase.com/servo/cys/s2220

[@boosieboo497]

Dam this is 8yrs old. Been a minute

[@Captncouth]

would it be possible to splice the servo into the BEC, or would that just mess things up?

[@HarleyDesignsInc]

You could, but you need to run the signal wire to the RX still and having a common ground plug is also a good idea to help keep an electronic "noise" that may be in the system down.

[@theirishaxe9405]

What output does this bec come with stock before you have to also buy the castle link? Like what voltage is the bec putting out just out of the package?

[@HarleyDesignsInc]

I believe is around 5v.

[@theirishaxe9405]

@@HarleyDesignsInc k thank you

[@nazreenrostam1340]

Thats means bec/servo in channel 1..esc in channel 2 rite? If dont have wire, channel 1 bes, channel 2 servo,esc channel 3? And remove the red wire from esc..do i rite? Ty for help

[@HarleyDesignsInc]

Servo always in channel 2, ESC always in channel 2. If the BEC is plugged into the receiver, it can go in any other open slot.

[@campbellj78]

With the Y splitter on the servo do you still need to remove red wire from ESC?

[@chaplinnone1274]

Say, if I was to install a bec the quick way, would I still need to solder the two wires to the battery?

[@HarleyDesignsInc]

+Chaplin Johnson yes.

[@Derekuda2012]

Is the BEC waterproof? Or will I have to plastidip it myself?

[@HarleyDesignsInc]

It needs waterproofed.

[@xxgg]

Can I use CC BEC to be wired between battery & the load? (for a non RC related project) to limit the output voltage? Also, if I am using 7.4v but receiver can not handle that... I should be RX bypass adapter, right?

[@HarleyDesignsInc]

xxgg You are correct on both accounts. Just make sure whatever you have the CC powering is not pulling more power than it can supply.

[@xxgg]

Harley Designs I am actually planning on using the CC BEC PRO. It's got two output plugs, can I combine reds & blacks wires together for I guess one output?

[@Team-Fraser]

Do you need to waterproof the Castle BEC?

[@derka5581]

Thank you for this video!! This helped me with how to hook one up.

[@Toysojah671]

@Harley Designs do i still need to use the cc bec with mamba micro x2 if ny servo is direct powered

[@HarleyDesignsInc]

If you got one of them that has NO INTERNAL BEC then yes you do. Because it will be what has to give power to the receiver to function.

[@MrKingNica]

If you use a by pass adapter do you still have to remove the red wire from the ESC?

[@HarleyDesignsInc]

No you do not.

[@MrKingNica]

Harley Designs thank you

[@Hanmieson]

I'll make that bypass adapter myself :)

[@joe6727]

any info on 2 steering servos? My summit doesnt have an extra receiever slot so thats my only option

[@HarleyDesignsInc]

+Jo E you can run an adapter that will put power to the servos directly. It may take some wiring work on your own though.

[@donaldhenke2750]

is a bec a voltage regulator

[@that1guy803]

With the holmes adaptor i dont have to soldier the red and back wire on the bec to the esc

[@HarleyDesignsInc]

No, you still have to solder the power.

[@jonathanjo4273]

[@BOBANDERSON5150]

Will this BEC emit radio frequency noise?

[@Fotoman08]

love your videos. where do I but the bec connector to the futaba r2004gf receiver?

[@HarleyDesignsInc]

+Felipe “PhotomanRC8” Arroyo what connector? No additional part should be needed unless you want to use a Holmes Hobbies bypass adapter.

[@Fotoman08]

+Harley Designs if I don't use the bypass where do I connect the bec to the esc?

[@jeromebullard6123]

Isn’t there a way to program that BEC without the link module? I’m pretty sure there is.

[@HarleyDesignsInc]

You can use a field card, but that was released after this video was made. But you need one of those two items.

[@jeromebullard6123]

[@DADDYJAMES843]

good info

[@hoegie01]

Hi Harley, Thank you - this was very useful. I'm wondering though - I have this HH ESC: holmeshobbies.com/Holmes-Hobbies-TorqueMaster-BR-XL-HH-TMBRXL-Waterproof.html It states in the desciption that it has a switchmode BEC. Do I still need an external BEC in that case for my Gelande II? I have a Savox SG-1210SG and a Novak 35 Brushed motor in it and I plan to use it on 2S only...

[@HarleyDesignsInc]

This is one of those situations where you may be ok without one, but it will depend on your battery as well. Savox servos are a little less efficient then some of the other brands so you may be right on the edge of still wanting to add a BEC. I tend to lean to the safe side and would say add one, which would also give the option of boosting the voltage a little if you wanted just a little more speed/power.
