Turnigy 5A (8-26v) SBEC for Lipo

 reztya 1 points

yes, i use Red Brick 60A ESC(opto) and Turnigy 5A (8-26v) SBEC for my ducted fan jet, and they working correctly.

All depends on how much each of those servos draw and the weight penalty you are willing to take. For reliabilities sake, having this BEC will ensure dependability and proper power distribution. While I suspect the 9g servos won't be an issue, I would use it for sure if I had 17g servos all around. Find out how much each of those servos draws (info should be available as part of servo specs) and if it all adds up to around 1A your built in should be fine but more than 2A and you would want of 5A BEC to be on the safe side.

In addition to Rad2009, I wonder what the output voltage is for you ESC, for FPV I always us 6V as it helps the RX to maintain signal better if you are using 2.5GHz. If you use the BEC make sure you issolate the SBEC from the ESC by disconnecting the red wire.

 The Bear 103 points

Do not run a UBEC in parallel with a BEC of and ESC always disconnect the red wire from the ESC.

directly from your battery pack, to your power/bind input on the reciver :)

1) remove ur red wire from the esc which goes into the receiver 2) connect SBEC parallel to the ESC and battery 3) connect the output wire from SBEC with ferrite ring on any free channel of ur receiver done.

 Laxmikant 533 points

don't cut it just take it out from the connector so that in future u can use that esc without an sbec

 The Bear 103 points

You can extract the red wire from the plug by carfully lifting the small retaining tab on the plug and pulling the red wire. It is esential that you do this or the two BEC circuits will be in conflict and either over heat or not produce a reliable voltage to the RX causing brown outs.

 The Bear 103 points

If you are using only 4X12g servos then the ESC BEC would be Okay but I supprised that you are using just 12g servos with an 80Amp ESC and 6S! Thats in exess of 1760Watts big power so big model? Or too big an ESC you should not use an ESC more than 20% the power draw of your motor with brushless as the controller circuit has to work too hard which can lead to problems. If it is a big plane then use a bigger UBEC and Bigger Servos.

i had issues with this not handling 4 digital servos and f-tek31ap on 3s lipo, everthing resets, this is designed for high input voltage and you should test it contiuesly. on PRODUCT ID: TR-UBEC 3amp it work flowless but only for 3s, this HV 5amp might work right for 6s however, but be sure to put a voltage protection in parallel with the ubec PRODUCT ID: TURN-VP if this still malfanctions! it has something to do with the design ground loops!

 jbx907 182 points

the PRODUCT ID: TURN-VP should be plane in the output 5v/6v side where there is an extra servo socket!

Thank you the bear.
I am preapring the 6S 70mm EDF plane .
Expected max. current draw at WOT is ca. 55A. That's the reason why only 4pcs of mini metal servos are needed even over 1200W of elec.input.
What do you think about this BEC as a external one after disabling buit-in one for more safety? Is it worthy?

 The Bear 103 points

On my EDF models I use the 5-7.5 Turnigy UBEC (TR-UBEC7.5) with Turnigy Digital servos (TGY-A55H)as my jets are 8S and had no problems. For your 6S set up either UBEC would work. I must say I dislike using the BEC supply from ESC's and much prefer using separate UBEC's but others like to keep it simple or are short on room just use the ESC. In my time with EDF and High performance Electric aircraft I have had several ESC BEC's fail and touch wood not a single UBEC.

 The Bear 103 points

I would use just one to power the receiver directly from the battery. I would not use 4 ESC with BECs and definitely DO NOT connect more than one ESC with BEC to a receiver.

 kekelala 307 points

Double sided foam tape with small cable tie should work

 bwoollia 320 points

Please don't use this on a 550! 5A is marginal for a 550 sized helicopter (especially FBL) and this BEC is not actually rated to 5A (check the reviews). I purchased this for a project and deemed it un-airworthy, it is now used for bench power.

 Artelian 21 points

Maybe because of this, my Hexa is unstable ? Before mountin this SBEC....was fly ok in hover. Now is a little unstable and drift. So I will have to eliminate this oe and fly with the ESC BEC ? For the moment, I do not have other for change, and will take to long for shipping. Tank You.

 sfactor1 940 points

bwoollia....a hexacopter is not a helicopter and it has no servos (except maybe accessories like a camera gimbal)!! this thing is way overkill for your hexa. you do not need 6v 5a to power your receiver as that is all that this is powering. if you already have this just mount it at the cg and verify that everything is balanced. if mounted properly this should have no impact on performance besides the weight penalty which isn't too bad relative to the AUW

 Grimmm 68 points

For my plane,I have 3 of them. it work with a lipo 2S 4000mAh and 7 servos towerpro MG946 (12kg) I haven't any problem. And it don't need cooling.

 The Bear 103 points

I have had no problem with the ones I use on helicopters. Your biggest load will be on landing with CROW Braking and that will be due to the large diffections on the ailerons and flaps (4 servos) I doubt unless it is a very big glider you would get near the upper end current draw in flight or even in crow in fast decent. Never needed cooling even in hard 90 sized heli flight.

 jbx907 182 points

i would use this on 2s, 3s up would be a better aproach, minumum volatge is 8v normal volatge of 2s is 7.4. just a precausion, i have got reset malfunctions of my F-tek31ap 4x tgy375mg using it on 3s, probalbly the long wire leads ground loops, if you have this be sure to insert PRODUCT ID: TURN-VP capacitor on the 5v/6v side sircuit! im not saying it cant handle the circuit, the out just becomes so unstable and probably would use it for a differnt circuit! im not using PRODUCT ID: TR-UBEC 3amp and des not reset even without the voltage protection capacitor!

I have it on the plane and a 450 pro, works flawlessly but my advice is do not ask the 5 amperes and consuming at most 4, and I say that is that the use and it's going very well.

 stewjw 217 points

Thanks. The BEC is just powering my receiver & servos. I have a separate cable going direct to my OSD & camera, a BEC is not needed for those. So I guess I should be OK.

 The Bear 103 points

I have three of these, two in helicopters (one Align 600 and a Logo 10)and one in a petrol powered aircraft and all have been great. The fixed wing aircraft has flown for over 15Hrs and the helicopters over 30Hrs between them, I think that speaks for itself.

 Stuart 7 points

I run 1 in a dragster, and trust it in this application. Had an electronics technician say that it has 3 amp components, at continous draw. Should have good reliability, up to a 15kg servo.

 old motohead 70 points

i have three and one of them is in a gas off road race truck two in quad copters.and ive used them in my six channel helis..these are all still working perfectly

 Zahid Rasheed 70 points

It seems to me your sbec malfunctioning... let it check by any good electronic expert .

 Ara 10 points

I would try setting the little jumper to 6 volts, it might be that the SBEC isn't supplying enough power to power your electronic equipment.

 Erik 4 points

How do you have it wired. I would say it is making a bad connection somewhere

 kekelala 307 points

Either bad connection or faulty unit

 Daniel 2 points

Hi - this BEC has a minimum Input Voltage at 8V, your 2 S battery brings only 7.4V* so it wouldnt run in this constellation.

*dna001, yes that's true but it won't stay that way for long *) At working voltage then he will still have the same problem as it's under 8v for most of the average flight.

 wolfes1126 3344 points

HI,
the Ring is called a FERRIT RING and you can use it, by wrapping the POWER CABLE a couple times through t he Hole around the Ring. This will minimize or eliminate the Distortions that may get produced by the Flow of Power through your positive/negative Wires to feed the SBEC.
If trhis Answer was any useful for you please let me get rewarded. Thank you

Wrap the wires to the ring 5 times.

Also disable the red wire on the ESC.

 Thiagobarreto 23 points

is used for the cable wraps inside. to avoid interference in rx

 Sangre 22 points

If your ESC has a built-in BEC you can only use it, just plug directly to the reciever. Separate BEC only used if ESC does not have built-in BEC.

 dippytwitty 155 points

Sometimes, people use the separate SBEC because it can provide more current - in your example 5A compared to 3A typical on most ESCs. In that case, you can just cut the red wire (middle of the 3 wires) going from the ESC to the receiver so it doesn't provide any power, and plug the SBEC into receiver where it says 'BATT' In your case, however, 3A should be plenty to power 4 micro servos, so if your ESC provides power, just use it by itself.

 tmncm 9 points

Sangre and dippytwitty many thanks for your answer, in this case I have bought a hobbyking brand ESC 45A, can you confirm it has a built in 3A ESC? Thanks all

 dippytwitty 155 points

The only 45A ESC that I can see for planes is the SS Series 45-50A ESC, if that's what you bought then yes, it has a 3Amp BEC. Enjoy!

 tmncm 9 points

Thats it thans dippytwityy

 crashd 103 points

Most 45a esc's provide around 3a to the bec. I'm assuming you're using 9g servos x4? (electrifly lancair?). The ecs will power your servos and rx just fine, and if its the airframe I'm thinking you don't need the extra weight.

 Uberfest 31 points

 rwallage 95 points

Any model with 4 or more servos I would use a seperate SBEC. The one included in your ESC is OK, but why take the risk? If your ESC fails, you will still have control over your servos, and your model. Connect the SBEC to the ESC wires going to the battery, and plug the servo type plug in any free channel of your Rx. If you don't have a free channel, use a Y-lead to any channel, BUT NOT the throttle channel. On your ESC disconnect the middle (usualy red) wire from the connection to the Rx to

 Shahar 15 points

you realy dont need to .. unless you want to Backup your BEC with another BEC - for that you have power box .

 edudominguez1 46 points

technique could use two and would like to use one of 10 A but with more mess of cables and connections that could cause failures in the connections.

 daniel22101982 45 points

no because you il have 10amps trough the two becs and they only support 5amps you ill blow up

 MyDSi 114 points

I would not recommend to do so ...

 turbo raven 5 points

No I think that to sell 10 amperes, you should take a secured power box, 10 amperes appearing to me for your receiver a lot, furthermore I would not venture to feed twice a receiver on two different ports without dual power unit.

 przemeku6 6 points

you can try it but i will strongly recommend to solder 5 Amp diodes on output wires to prevent possible floating currents between 2 bec,

 Rcforme 210 points

Don't do it, get a more powerful BEC. It should cost less, weigh less and cause less problems. Hope this helps you!

 Anna 6 points

better bec

 rowdyjoe 61 points

It means "switching" Battery Eliminator Circuit ....as opposed to "linear" BEC. A switching (aka switch-mode) BEC is more efficient than a linear BEC and will deliver a more stable and constant current to your receiver. SBECs are also more reliable and will handle the rated current where linear BECs usually under-perform and will not support their rated current.

 Kenneth 5 points

Linear BEC reduces voltage by using resister network to get to required voltage. SBEC uses a switching fet (turns on and off many times per second) to reduce voltage. this is a much more efficient wat to do this and also generates less heat than resistive network.

no it is bec (battery circuit eliminator) just set the lipo 2s 7,4v or 3s 11,1v to 5v or 6v. is not a esc.

 Ivan 1 points

yes, i know, it is a bec, but someone tell me if i go to use a leopard 1900kv with the t180amp and 2x3cel lipos i will need to connect one of this bec to the sistem, this avoid the internal bec of the t180amp heating ?? this will work with this configuration?

 Anna 6 points

yes it will be work as power for reciver

 vasy1 605 points

Yes, if you remove the red wire from the 180 amper, you can use this SBEC to power your receiver and servos. You can do it directly from the main battery or you can add a secondary unit.

 vladimir olegovich 1 points

Yes, connect will work out Turnigy 5A (8-26v) SBEC for Lipo on free output target (either the power port of the receiver), don't forget to remove the average overhead turnigy 180 amp connectors.

 MyDSi 114 points

THIS IS A BEC 8V - 26V in - 5V or 6V out. This is not for powering a BL Motor. Its not a ESC!

 miket65 27 points

madruga , are you sur that it is ok with a ZIPPY Flightmax 2100mAh 2S3P Receiver Pack , for exemple ? because input min is 8V and 2s is 7.6 -7.9 V and more than 8V at the beg, but what happen when reach 7.6 V, Sbec already available ? or ?? tks

 madruga 89 points

the internal bec of esc is hot because the linear bec is not eficient. the switch bec is more eficient for work. good fly!!!!

 teseo 1 points

there is usually no need for SBEC if you have an electric boat, because the ESC is usually already provided with the circuit-UBEC SBEC to go through which power the servos and other equipment. If you have a combustion engine surely you need this device (UBEC or SBEC) to lower the voltage of the lipo and be quiet not to burn the servo and receiver.
