well, can i use this as a valtage regulator for my 26cc petrol plane RECEIVER. i Planning to run on 2S lipo. But 7.4v will cause me to burn the servo. IS This the correct accessories to use ? thanks

Irrwitz (22 points);
Yes, its the right sing to reduce the Voltage to 5 or 6 V. Put it between Lipo and Receiver, it works fine.

Do I need two lipo to power this?1 for ESC and one for UBEC)

Reply:

Dean (208 points);
you can re-solder the power leads of the ESC and BEC to go into the one battery.

I have a plane that has a 50AMP ESC without a BEC. I bought this UBEC to power the receiver. Question..... Can I power this UBEC from my 11.1VDC lipoly flight pack? Would this work?

Would this not be the same as if I had a 50AMP ESC with BEC?

Reply:

Dean (208 points);
Yes you can, and yes it would be the same.

1. How do you connect a 3 cell Lipo?
2. What is the max discharge LiPo battery that can be used?
3. If I have a 1000mAH 10C Lipo, how long can I use the battery?

Reply:

stgram12 (2 points);
You just connect the 2 main leads(black and red) of the battery or the 1rs and the last lead from the balance socket(be careful they might not handle big current!) to the 2 input leads of the BEC.It doesnt matter if it is 2S,3S,4S,5S, as this bec can handle all those types of voltage!

As this will suply 3A 5/6V the max current drawn from the lipo will be max 3A. So you can power this even from ordinary AA batteries!Of course you can youse all types of lipo, which can provide at least 3A for the bec.But dont forget the motor which actually drowns the battery much more then that bec!

A 1Ah 10C lipo can supply 10Amps.So if you are going to use that bec on its full capacity you can connect a motor which will require a max of 7Amps continuously.

I know i love to write a lot, hope I answered your questions! :)

Can i put this between the ESC and the RX to make the 23v from the 5s lipo thats is connected to the ESC lower ( 5v) so i can use the servos from the 5s ?

Reply:

Coma004 (23 points);
Yes, you can power this ubec with your 5s lipo.

Excelente regulador de tens�o. Recomendo, utilizo para utiliza��o em meus receptores.

Ron Smetsers (36 points) 5/28/2009
I still fly on 35mhz, and my servo's are jittering quite severe when i walk away 10feet with collapsed antenna.
When i pull the antenna, the jitter is gone, but i'm not sure about taking it to the air.
What can i do? (exept buy FASST)

Reply:

3900Kv (48 points);
1)Fly with antenna fully out.
2)If there is some glitching as well you can try cleaning the pots.
3)You can use a UBEC to sort any power issues with servos but do use a ferrite ring on power wire to Rx.
That should help.

mamba (2 points) 5/17/2009
ok, don't ask me how I found out...this UBEC is not protected for reverse plug power.
happened to someone?
did you manage to fix it?
what did you replace in order to fix it?

Rixx (27 points)
I still dont understand where should I connect It. To any free channel and use ESC on throttle channel? My guess is - ESC and BEC via Y cable to the battery, and then I would pull off white(signal) wire from ESC`s receiver plug and put it to BEC`s black connector. Then plug it to receiver throttle channel. This way I would supply RX and servos with BEC power, ESC + BEC with raw battery power and throttle signal from RX at the same time. Would this work? I plan to use 6 - 8 servos on my plane, I think I cannot without BEC :)

Reply:

William (3 points);
Easier way is to ,yes connect BEC to any open channel and ,Yes connect ESC to throttle, BUT disconnect red lead from ESC to receiver and heat-srink so it doesn't short.

Is this Ok for 6 S ?

it says 5s only but 23V ???

Mines on a 6s. 25v fully charged. Seems fine with over a dozen flights.

What is the default setting?? Mine came with the jumper in the same position as the one in the photo above. What V rating is this at? What jumper setting is what...5/6V????

Reply:

waynemia (116 points);
The picture shows it in the 6V position. Just pull the jumper off and move it over one pin to slect 5V.

Reply:

3900Kv (48 points);
Default is 6V position but measures at 6.47V. To switch to 5V just move the jumper to other free pin.

Reply:

Dean (208 points);
leave it a 6v, it gives more power to the servo motors which provides better speed and more torque.

piruja (41 points)
Thanks Davide, do you know if exists any plug that allows that without peel the cables (an special two to one plug, two ESC **> one batery?

Reply:

Gary (0 points);
yes. you can make(or buy) what is basically a "y" cable. Like this one ***********hobbycity****/hobbycity/store/uh_viewItem.asp?idProduct=2155&Product_Name=HXT_T-Connector_Parallel_Pack_lead but with the male and female plugs reversed.

piruja (41 points)
may you help me with the lay out of the connections? I mean between the UBEC and the ESC, battery and reciver. Thanks

Reply:

davide (46 points);
The black plug has to be connected to the receiver (any free channel is ok) for the power suppyof receiver and servos.
You can cut the red jst plug and connect the red and the black cables together with the ones of the esc to the Battery.

Is it enought to power 5x 3004 futaba servos?

Reply:

Deryn (64 points);
Do you know the current draw of the 3004 under load?

The UBEC has an output of 3A.
As long as the max current draw is 600mA (.6A) or less, it will be fine.

rmartignoni (17 points);
I'm planning to use it with a 2S 1300mah LiPo in a 3D plane. Do you think it would be fine?

Reply:

Kyle (45 points);
3004's in a 3d plane????? wow, but it should work yes.

Reply:

waynemia (116 points);
Hi, put a servo on a servo tester and measure the current under load. Measure the reciever current. Add receiver current plus 5x the servo current. Multiply the total by 1.2 (20% savety margin). If it is less than 3A, you are good to go.

Eseck90 (163 points)
Can this ubec be programmed? How?

Reply:

Deryn (64 points);
It has a switch to choose output - 5v or 6v. That is the only thing you can change.

Reply:

waynemia (116 points);
Just a jumper. The blue squate in the picture. It is not really tight. I would juggest a little hot glue to make sure it stays put.

Eagle (124 points)
Is this a linear-mode BEC oder Switch-mode BEC ???
Best Reagards!

Reply:

Deryn (64 points);
I assume it is a switching BEC. De******ion says it is good up to 5S and states a 3a output.

Reply:

waynemia (116 points);
It is a switching unit.

Christian (0 points)
Are there some auto-cut off on this UBEC, if the batteries are very low (under 6,5V)
?

Reply:

Deryn (64 points);
UBECs do not have a cut-off.

Reply:

waynemia (116 points);
This is good since you don't want the radio receiver to stop.

High Quality, Low Price

Angus P

High Quality, Low Price, what more could you want?

It's not the same as the picture, but it actually looks better.

Here's some data I collected with a Fluke DMM:
Battery Voltage (unloaded): 6.477v
Battery Voltage (loaded): 6.466v
Output Voltage (5v unloaded): 5.376v
Output Voltage (5v loaded): 5.318v
Output Voltage (6v unloaded): 6.307v
Output Voltage (6v loaded): 6.323v

Load used was 2 3.3v 40,000mcd LED's with 182ohm resistors.

Hope this is useful to someone )

Rock Solid

Jason Hurst

Hey guys this is one great UBEC unit. 3 amps output will handle most anything I can throw at it. I am using it in my Sniper XL with 5 Hitec HS81's set to the 5 volt setting with an 11.1v 3200 MaxAmps pack. It provides a solid 5.3-5.4 volts even at maximum amperage. I was a little disappointed with the smaller gauge wire for battery hookup, but the max amps achieved at any time rarely goes above 1.5. So the intermittent burst is ok for the smaller gauge wire. I recommend this. For safety sake secure the voltage selection jumper, it is a little loose and can rattle loose.

Not correct specs

Osiris Ra

I ordered this UBEC because of the size
and weight and was disappointed because
the weight is over twice as much (14g)
as the indicated spec. Also it does not
look like what is shown.
The picture and specs need to be updated.

Works as a Nicad / NiHM replac

Mike Passey

I've been using the UBEC to replace the onboard battery on my Nitro Planes. It works well and its nice to be able to switch between 5v and 6v to see how the plane handles with faster servo speeds. So far the setup works better than a Nicad or NiHM battery that slowly loose voltage. The UBEC maintains a constant 5v or 6v.

just a ubec and nothing more

Kostas Brouzas

Definately 5 stars for the cheapest ubec.

It does the work with no problems.
5V-> 5.2V no load, 5V 0.8Amp
6V-> 6.2 no load, 5.99V 0,9Amp

No fancy leds, but you may not nead them.
No interference no noise,
also tested with corona receivers.

Nice flights in Greek sky

The Best I have tryied up to n

Panagiotis Mourelatos

I always use external BEC to avoid crushes from overheat or other similar reasons. This is the best I've tryid up to now. A little heavier than it says, but cause to problem to me since I use it with big planes. No heat, no noise, low voltage drop with 5 servo working - (4,8 Volt)

No problems

Michael Nakamura

Good insurance for my 3D plane with 4 servos. I installed it on an unused channel and pulled out the red lead of the speed control to receiver wire.

HXT UBEC

Bon produit, pas de tops m�me sans ferrite.
On peut le brancher sur le r�cepteur et mettre un interrupteur �quip� de prises bec entre ce module et un pack 2 ou 3S.
Le fil c�t� r�cepteur peut sembler de section un peu faible mais pas de probl�mes sur mon Piper de 2m10 �quip� de 4 servos standards. J'ai r�alis� un cordon bec/Jst XH pour le brancher directement sur le pack de propulsion.
Assurer le cavalier de s�lection 5/6V avec un scotch !

HXT UBEC

Boris Mazor

Thank you for good and small device.
I hope it will work as posted.
Just one concern: output wires to small for 3A, need to be at list twice in dia. I going to replace them for 18 gauge Thanks. Boris Mazor (electronic engeneer)

HXT UBEC 5/6v output, 5.5~23v

Mike Mc Mahon

Great product for small planes.

This lets you use lipo batteries for you reciever. No more charging up just before flying as the lipos will keep there charge.

Just one caution if you use these on anything more power hungry than a 40 size trainer you may run into problems as you are likely to draw more than 3 amps although these units seem to handle 5 amp peaks for very short periods.

My advice alway er on the safe side for bigger models get a bigger bec.

for anythigng less than a 40 trainer these are ideal and at a great price.

Great little product

Louis Dionne

It has a common JST connector on the power side. Choices of 6v or 5v output. Saves weight and always have the receiver side ready to go...Buying a couple more.

This Ubec is a very good unit and simple to use, I prefer to put Ubec in ALL of my setups (I dont use the Bec from ESC speed controller) because 3 main reasons, 1) it made my speed controller run cooler, 2) The ubec give cleaner voltage and constant and more AMPs to the Receiver/gyro/servos, 3) in case the ESC fail the Ubec will keep giving power to my receiver & servos (fail save), I highly recommend and for the price cant go wrong.

Great UBEC! Great Value!

Roberto Bunggo

Solid UBEC. I use it for my Spektrum RX's and I really like the JST plug connector on this ubec. I just soldered a male JST connector onto the deans plug and i can now switch UBECs out to the plane i want to fly. No need to buy separate UBECs... just plug n play!

Not exact 5 v but works fine for me
for the cheapest ubec.
5V-> 5.2V
6V-> 6.2 n

No interference

Great for my FPV project

UBEC

Orestes Guidali

It�s a good idea, to use UBEC, because you have garanty that your model don�t crash without the radio signal. If you use ESC with BEC, you can use UBEC, disconnecting the red wire of ESC radio connector.

lighter, more amps, dual volta

JIM CLARK

Very impressed with this little UBEC. Input: 2 x 7.2 lipo's 800ma each in parallel for a 1600 ma ride! I measure 5.34/6.23V swapping jumper. Much lighter than comparative 4/5 cell Nmh and lipo's keep charge when they are asleep. More current to motor and electronics with individual power source. I will suggest to all my fly buddies and will order several more for myself!!

Excellent BEC

Alejandro Yanez JR

This unit has run very cool after hard 3D in my Dragonus 2 pro.
Weight averaged 13.1 grams across thre units that I purchased. No switching interference that I could tell, so using a ferrite choke is optional, saving you weight.
I would definitely recommend......

First time ever using a UBEC and it works great using a Super Simple 50A ESC. Using it on my Parkzone T-28 with a Turnigy 35-42 1250kv. Perfect combo. I'll be getting motor of these, highly recommended.

These are great - I bought two and both work perfectly. It allows you to use a 2S lipo as your receiver battery, which saved me heaps of weight in my .10 size spacewaker (compared with nicd/nimh). I also use one in my 120 size tiger moth, and because weight is not an issue in such a big plane, I can use a battery with a greater capacity.

You can choose to run it at standard voltage or you can set it for 6v (replicates a 5 cell receiver pack).

Highly recommended.
