ok, if i have a gWS c-130 with 4 brushless motors and 4 esc`s, instead of having to cut esc wires can i use this thing to send the signal back to the receiver/ email me asap

Napstr (86%)
No if you were to use it it would be seperate to the esc's - the esc's will still need to be all y'd together to get the signal back to the reciever and you will have to remove all of the red pins from the esc's to stop them interfering with this regulator. I personally would try and power diffeing groups of things (certain servos or reciever) from each speed control and avoid using a UBEC - as you have 4 controllers with BEC's onboard so by removing red pins and grouping together some servo red pins with a esc red wire you can power those servos from that esc - then one esc simply connects through the reciever and powers whatever is left as per normal. This way you are sharing the load between all of the bec's so none are likely to get hot and fail and also providing some redundancy to stop loss of control if one does fail for some reason providing the one that fails isn't powering the reciever of course!

baylordsmith (64%)
This is attached between the battery and the reciever to limit the voltage to 6 volts

midrian (34%)
Unfortunately no.. this is only a UBEC (think of it like a stand alone battery) it does not do any signal handling whatsoever.

midrian (34%)
This is only a UBEC and only provides power to your receiver. (think of it like a stand alone 4 or 5 sell nimh battery getting power from your lipo) It does not do any kind of signal processing.

Derick Z (36%)
What battery connection does this UBEC have?

Saurabh (98%)
This does not have any connectors attached. you can attach connectors of your preference.

This customer was awarded a credit for their answer.

Derick Z (36%)
It doesn't have any battery connectors OR receiver terminal? Meaning I'd need to buy a connector for the battery AND a connector to plug it into the receiver?

Saurabh (98%)
yes. the output cable has the standard rx plug (JR servo) style. The input cable is just bare (no connectors attached)

Derick Z (36%)
Thank you very much!

demonGti (61%)
none, just bare wires.

Ceolwulf (42%)
You have to furnish your own battery connection or you splice into esc battery connection. All depends on if you want your rx to have a sepereate power supply or not.

michoc (62%)
It come with NO battery connector.

nrajesh@hotmail (73%)
Hi, This UBEC has no battery intake, Either use Micro Deans or a reliable battery connector. The intage wire is hopeless since it is 26 guage, and may require replacement. Overall this BEC is good and solves the purpose, I use this for a Yak 30 cc, with 5 Hitec 645 mg. No issues.
Happy flying, RajeshN

JOU (35%)
In the side that goes to the Rx it installs a connector standard JR* the bare wires that go to the LiPo, I weld them to the connectors of the battery.

matt64 (72%)
Non. There are just two cables.

Kai (50%)
it does not have a connector, just wires

midrian (34%)
This UBEC does not have any connectors on the battery side so that you can use your own choice of connectors. I have used mine with a male and female deans connector with a piece of wire between so that you can plug it into your battery and then into your speed control. I have also used it with mini deans plugs with a stand alone battery. or you can just solder it onto your speed control's deans plug in parallel.

midrian (34%)
This UBEC does not come with a battery connector so that you can use whatever connector you want. you can solder it directly to your speed control's deans plugs going to the battery in parallel or make yourself a male to female plug that connects inbetween the battery and speed control (heavier), or if you are using a stand alone battery something like mini deans will be fine since the plug will not have to support a lot of amps

michoc (62%)
It come with no connector at all (in and out)

'm looking to use this with a 5 cell nimh pack, which delivers over 7.5v charged, and i need it for a receiver and servos that need 6v. What happens when the battery drops below 6v if i have it on the 6v jumper? Will it stop or will it continue to supply the same voltage output as the input voltage level?

Martin Lang (77%)
and what happens when it hits 5.5v for the listed input minimum.. shut down?

Saurabh (98%)
you will get 6V even if the voltage drops to 5.5V

thelastosirus (53%)
You are wrong. The switching BEC needs at least 1V over the selected voltage. Below this it shuts down. It only reduces voltage, not increases it.

jenius8477 (27%)
same output as input below 6v

nrajesh@hotmail (73%)
Hi, You can directly use a 5 cell Nimh pack to your RX set up, preferablly 2500 mah. This will not damage if your RX device can take up 6 volt.
Regulator will be effective if the input voltage is 2 volt more than the output voltage. Say use this BEC if you have a 7.4 v battery.
Regards, RajeshN

baylordsmith (64%)
You need to go to a lager battery pack to ensure proper operation

midrian (34%)
I believe it will continue to supply the same voltage. I have used 5 cell nimh's that delivered over 7.5v directly on receivers and servos without problems though.. it was JR R700 receivers with hightec hs81 & hs85 servos (6 servos). I think that as long as you are using decent quality hardware the 7.5V should be ok.

midrian (34%)
I presume it will just continue to provide the input voltage. I have used 5s nimh packs straight on JR R700 receivers with 6 Hitech servos (HS81 & HS85s) quite a couple of times before and have not had any problems. So I think as long as you are using a decent quality receiver and 6v servos you should be fine. nimh nominal voltage =1.2v nimh max voltage = 1.5v 5*1.5 = 7.5v

htamimi (27%)
does it work ok with JR 2.4?
are there any Interference?

LeSquale (58%)
I am using it with my Spektrum DX7, which is the same transmission system as your JR, and no problem at all. But it is always preferable to not put it close to the receiver...

This customer was awarded a credit for their answer.

Mattias (39%)
Yes. For me it does.

divay99 (42%)
Fantastic Product... Out of the world

deerhunt (23%)
I'm using it together in a FPV system and I can't find any "noise" with it

Aremon (34%)
You've got two in free-cable: red to " " and black to "-" abd two out (the same) cable

flying on (55%)
No worries, works fine with 2.4, very clean output with no noise...

deerhunt (23%)
Yes it works fine with my JR DSX7 DSMJ system.

smasher41 (51%)
i use this with a ar 6110e reciever and havent had any issues after about 10 flights.

Fly_Fast (32%)
Yes it works !

ECTOR (61%)
Hi htamimi i use that for long time on my JR 388s with 2.4 module of ASSAN factory and also rx ASSAN with no problem at all

mutlu_tekir (43%)
yeah works and no interferance on my system.

Burdo (74%)
I've bought two of them, and so far so good. As an added safety measure, put a toroid on the end of it, which should cancel out and noise which might effect nearby electronics.

steven (59%)
None so far from me. Same with 72mhz. No interferene at all.

Ceolwulf (42%)
It should work. I use mine with a dx6I and have not had any problems. With a 2.4 ghz system you should not have to worry about introference like an fm system.

nrajesh@hotmail (73%)
Hi, I am using with my JR radio RX D7000, D9000, and Spectrum AR 7000 since 3 years, no issues when using glow engines.
Thanks, Regards, Rajesh N

michoc (62%)
Yes it work with JR (Spektrum) 2.4Ghz receiver without interference.

htamimi (27%)
does it work wit my DLE30 ignetion and put another one for 6 digital servos? (25% extra)

Abraham (20%)
you should check the total amp draw on your digital servos. I think it would work if you are using no more than the 3Amp total draw at any given time.

htamimi (27%)
thank Abraham
how can i check the total Amps draw? Is there any device can tell me.
thanks

RichT (68%)
I would get a 10A or bigger BEC for 6 standard sized digital servos. This is more park flyer sized.

Saurabh (98%)
yes this will surely work with any ignition system. Ignition system (except for Zenoah) do not consume more than 400 ma

LeSquale (58%)
Yes for the ignition, no problem, but not for the 6 digital servos. The Turnigy 5-7.5A HV UBEC(caution minimum 3S) or the MEGABEC 8A (only 2S) would be more approriated. Otherwise the Turnigy 8-15A UBEC is an excellent choice.

Saurabh (98%)
Yes this is perfect for your requirement

daniel_L (53%)
NO too small go for a bigger one, like the 8A or 15A.

willy-riis (32%)
I use it with my DL30 with no problems at all, of course I use another UBEC 8A for radio (72 mhz)it is always better not to mix ignition with R/C

jenius8477 (27%)
it should

baylordsmith (64%)
Yes it will work. Use one set for 6 volts for the reciever and one set for 5 volts for the ignition

13/02/2010
olisoft (30%)
The diode on input side is for protecting the device or does it have also some other function?
My daughter changed the polarity during connecting end the diode burned. But the ubec seems to work without it(i desoldered it...).
What type exactly is the diode? I'd like to replace the burned one.
Thanks a lot for the answers. :)

Saurabh (98%)
Diode is only for reverse polarity protection.

olisoft (30%)
Thanks! :o)

ncuz (60%)
you can use any kind of small amps diode such as 1N4148 or 1N4001 (reverse pole-for protection)

baylordsmith (64%)
Yes it is for reverse polarity protection. Dont know the numbers for the diode. Tey customer support

ECTOR (61%)
I have two of thease products.Nicely working on my HK450 hel with one digital servo three regular servos and also gyro.
Now i order one HK 500 heli.That use 4 digital servos and 6 cell battery (22.2v) can any one use this UBEC at 22.2v ?

manuel00 (54%)
i have this ubec in a extra 330s 2,10m wing span witch a 2000mAh 3s Lipo. 5 digital servos and its works great, dont heat, sorry for my english!

3/01/2010
lloydcole (69%)
also this must go upto 6s surely, even the hobbywing 1 does plus it says upto 23v and a 6s is 22.2v

3/01/2010
lloydcole (69%)
does this come with jst plug like the hextronic one?

nrajesh@hotmail (73%)
Hi, No plugs for battery input, use a micro deans or JST kind of plug. Beware of the input wire, so thin, say 26 or 28 guage.
Regards, Rajesh N

baylordsmith (64%)
It comes with bare wires for your plug

29/09/2009
hatvaniz (59%)
Is this UBEC usable for the ignition system of a gas engine?

Saurabh (98%)
Yes it is. Ignition systems do not draw more than 400ma USUALLY.

winson (31%)
Hello, Can I plug a 2s 610 20C baterry o thIS UBEC?

thanks

RoadWarrior (89%)
Yes, as description says input voltage is 5.5V-23V (2-5S Lipo or 5-15 NiMH)

Saurabh (98%)
yes you can,

31/08/2009
crigotti (25%)
I have 2 of these UBEC's and mine are different from the picture because they don't have the large capacitor on the output end of the circuit board. Is this normal?

Saurabh (98%)
now it comes with the capacitor. you may have one from the old batch.

black_hawk (72%)
There is no capacitor on mine and i got mine only 2 weeks ago!

26/08/2009
Naval Warfare (77%)
How do you take this from 5v to 6v?
I know its the jumper, but what do you do to change it from stock?

Thanks in advance

boris (33%)
The jumper is that blue thing that you can pull off and you will see 3 pins(the jumper can caonnect just two pins). When you put back the jumper there are two options-5v or 6v(you can see that on ubec). It comes with jumper on 5v from stock(slower servo movements).

Naval Warfare (77%)
Thank you Boris!

Saurabh (98%)
remove the jumper. it will give you 6v output

25/08/2009
McQuack (62%)
Arrive with Rx and Battery connectors? or do you have to put the connectors?

Derick Z (36%)
Somebody told me it has no battery connector, but I dunno about Rx.

Derick Z (36%)
Update: It does not have a battery connector, but comes with the Rx connector presoldered.

15/07/2009
jooyeumi (27%)
I've used this bec quite all right but suddenly it stops and never come again, no red light on. What's wrong with it?

Saurabh (98%)
internal short of the mosfet

15/07/2009
boris (33%)
Do anybody use this ubec with 6s lipos?
Tnx

Saurabh (98%)
I have used it with 6 cell.. it works like a charm

26/06/2009
Joshua (46%)
Is this Ubec a plug and play or do you need to disconnect the stock bec from the esc first? Thanks in advance guys.

Beaufighter (-25%)
It is plug and play, but as allways you need to disconnect bec positive from esc (if any). Your reciever will not be to happy with power being fed from two places.

Fiddy$Trainer (89%)
My wife through away the manual where can I get on?

boris (33%)
If the esc does have inbuilt bec than you have to cut the red wire(white-RED-black) or better-take out the pin with sharp item...(so you can use it again if needed).
Insulate the pin(on the red wire) with electrical tape.
Connect(solder) input cables(red(+)black(-))with input cables on the esc.That's it. Plug both esc and ubec into receiver.

If esc does not have inbuilt bec than you just connect(solder) input cables(red(+)black(-))with input cables on the esc.

boris (33%)
The blue thing is jumper switch for Output: 5v/3A or 6v/3A
With 6v/3A the servo is faster and with more torque.

ministeve2003 (82%)
Be carefull running your servos at 6v some do not like that and will burn up...

23/06/2009
rwallage (39%)
Can I use this in a glider, between a 2S lipo and Rx?

machead (84%)
Of course. Just select the desired voltage, 5 or 6V, and the rest is just plug and play!

18/06/2009
zbig77 (34%)
Is there any kind of connector on the battery side? If yes what kind ?

machead (84%)
No connector at the input side, only the a JR styled connector at the output.

15/06/2009
KaiKai (32%)
Does this ubec have the Servo-Connectors on the output Cable or do i have to solder it myself?

Kai (50%)
it has a servo plug on the output connector.

12/06/2009
Sinesio Jose (46%)
Hi! Someone could tell me if is possible use this UBEC, for battery of JR receiver?
I entend to put an Lipo 7.4V But the receiver works just with 4.8 or 6 volts!
Thanks!

Pitufo (28%)
You can, this is the main usage of UBEC. Connect the input to the battery and the output to the receiver.

Suspecting you may be using it into an electric powered model, ensure you don't already have a built-in BEC in your ESC. If there is one disable it cutting or isolating the red wire from ESC to RX, this is enought to disable its usage. If your model don't have electric motor, ignore this paragraph.

Sinesio Jose (46%)
Ok, Thank you so much!!

motorhead (87%)
cost saver or not, it's nevertheless a great tip! Thanks cotoflyer!

5/05/2009
cotoflyer (73%)
You can move these bec's easily from plane to plane without changing esc's if you solder a male and female deans type connector back to back, then solder the red and black wires of the bec to the correct polarity of the deans, and wrap the assembly in electrical tape. I find this very handy and a definite time and cost saver.

electrafly (76%)
They have a plug and socket on them. But for only US12.03 posted you must be joking. I have heard of penny pinching. I live on a old age pension and I have one on each model that I use them on and they cost me AU15.93 each.

cotoflyer (73%)
This is exactly why I hardly ever post on forums. I'm not joking and would appreciate if you would keep such comments to yourself. Do you feel better after posting this and is any modeler better off for such a comment?

It is a time and cost saver regardless. It's also a suggestion for those who want to upgrade their power systems from 3 cell to maybe 4 or 5 cell and don't want to extract the existing esc from their model to solder the bec wires to their existing esc power connectors. My mother used to say that if you can't say anything nice....

electrafly (76%)
Do I feel better,(YES).A cost saver.(My mother used to say don't be a penny pincher).(only from the USA.)Is any modeler better off for such a comment, (Yes) now they no there is a plug and socket on them.

ministeve2003 (82%)
I solder an extra set of wires with small bullet connectors onto the esc wires and use bullets on the BEC, that way I can do the same thing... Not that I change stuff out alot... but sometimes I don't get around to scavanging all the stuff out of a model that I'm not going to fly again for months.... and if I want to pull a bec out to fly something else for a few weeks I don't need to buy an extra one... I mean come on... DO I really want 15 BEC's when I'm really only going to take a couple planes out to fly.... It's bad enough that I have 15 ESC's (actually probibly more)

also By soldering bullets instead of soldering directly, in a crash you have a chance (however slim) that the wire will pull out instead of ripping off the bec (I've actually seen that happen) Tight wires Break stuff, loose wires tend to last a lot longer...

buckman (47%)
I use this on small high-performance planes, like the Multiplex Funjet. I have encountered a few brown-out with my Spektrum 6100 shutting off. The restart comes in 3 seconds later and thank goodness I was at very high altitude. After installing the UBEC, no problems with punching full throttle. No more brown-outs!

Skypal (35%)
Can someone explain what the little blue plug is for?
It looks like it can be moved to other pins for some kind of change.
ernie

doyouflytoo (89%)
5v to 6v output. mine reads 5.29v and 6.01. The product photo shows it in the 5v position.

Skypal (35%)
Thans Ken Your answer came just in time. I'm ready to install on fledgling with 3 std servos.

Desmond (79%)
it says 5.5-23V (2-5S), is it safe to use 6S on it.

doyouflytoo (89%)
no, they do have a High Voltage one, but it's more money. A fully charged 6s is 25.2v

ministeve2003 (82%)
The Last one I bought, Said 2-6 cells on the back... so I'm gonna assume the answer is yes...

bothal3 (98%)
I also wonder why the rating was degraded to 5S AFTER I bought 12 of them? (Ha ha)

trxtc (65%)
im running mine on 6s hope it doesnt blow, seems fine though

mluyben (43%)
My guess is that it will work on 6s, but better is to change the 25V capacitor for a 35V capacitor.
I think this is what makes it 5s instead of 6s.
The 25V cap is a bit borderline.

Tadango (80%)
But you would like to destroy your plane? :)

Joe (45%)
Does this have a voltage cutoff built in? I would like to run it with 3S and would like the voltage not to go below 9 volts so the battery is not damaged. Thanks

Beaufighter (-25%)
The BEC is used to supply receiver and servos, you don't want them to cut when flying. Most BECs do not shut off, just for this reason (If BEC cuts, the plane crash, planecrash usually more expensive than battery damage, planecrash often involves batterydamage...) Use a voltageindicator if unsure of voltage!

RoadWarrior (89%)
Just don't fly until the motor stops...

Lucian (98%)
No, it doesn't. But TURNIGY 8-15A UBEC has a cut-off.

Sander, you're out of subject, man, you are a rookie, don't you? Inside an ESC, the BEC function contains the cut-off. So, the question is indeed a good one.
And, yes, you want the cut-off when flying, with the remaining juice in the battery you could land. For your information, there are a hard and a soft cut-off.

Lucian (98%)
...more precisely, the cut-off is for the motor.
Why a BEC with cut-off? For the planes with twin brushless engines, you want to cut both motors in the same time, so you disable the BEC function on each ESC (the red wire), use an external BEC.

minitel (73%)
You definitly don't want the ubec to have a cutoff-it is what is powering your servos and rx, and allowing you to control your airplane. Better to ruin a lipo pack by low voltage than lose an airplane when the ubec cuts of power to the rx.

Eric1180 (-53%)
I agree with steven this isn't a esc this is a pure BEC. you are the one that doesn't know what you are talking about. The real only purpose is for Nitro plane that want to use lipo battery to power there planes servos. You are comparing the cut off feature with a different thing. This isn't A ESC. A BEC IS ONLY FOR YOUR SERVOS. SO IF THAT CUTS OFF HOW....... CAN YOU SAFLY LAND IF YOU HAVE NO ******- CONTROL OF THE PLANE? Amuse me!

Lucian (98%)
Eric, why don't you read the posts? I've said it before, "the cut-off is for the motor." <** READ THIS "...For the planes with twin brushless engines, you want to cut both motors in the same time..." <** AND THIS And, btw, the BEC's aren't for nitro planes, we use just a battery, is cheaper. I suggest you to discover the use of BEC, before arguing on semi-forums. Start with the name: "battery eliminator...", and you will see that nitro planes still have the battery for the servos. PS Have you ever heard of SmartBEC? Obviously, not.

Beaufighter (-25%)
Well Lucien, it was you who said I was totally wrong and a rookie, while I actually explained the function of this bec correctrly..

Your advice of having soft/hard cut on a bec must be the worst. What is to cut soft? The rx? Or servos? How can you possibly land safely with cutoff on bec?

Like I said in my first post, if my 1000$ plane crash, the cost is no match to puffing a 30$battery. I like my bec to give power until the battery is completely dead.
