PostSubject: HiModel 8 Amps. 5V / 6V Switch-Mode UBEC   Wed Jan 02, 2008 4:28 pm

Hi all,

I'm planning to get it, and I'm ordering it at CHHobbies.

I've been using this product for a year with no problem , so I was thinking to get more amps to reduce a risk. Meaning looks alike that previous 3amp is not enough for my setting, even though the max burst current is 5amps. This is because Align are now re produce up to 6amps.

Here are the pic as below for the HiModel UBEC switch

Hi axen,

I've just installed one 5A UBEC 5v/6v on 3s1p lipo at 11v 1800mA, and it is very responsive and fast with 6v on my S9402 (cyclic and collective) bounce servos and all the torque that i've wanted, and i bet the 8Amps is much better tough. sunny flower

PostSubject: Some nomenclature clarification   Fri Jan 04, 2008 4:30 pm

Its interesting that a lot more manufacturers are calling Voltage Regulator "BEC"s.

BEC is short for Battery Eliminator Circuitry and is a system to step down higher voltage to either 4.8v or 6v from a single power source shared between the Drive system and also the power for receiver/ servo's.

On electric models, this is generally available on the ESC whereby it ELIMINATES the need for an external 4.8v or 6v receiver pack, thereby saving weight.

So the correct term here is actually a voltage regulator. Some good ones which i have used personally isfrom Duralite which i use on my Rappy 90SE. It is non-switched i.e. Linear Regulator, so comes with a heat sink (less interference prone) and runs of a 2s1p Li-Po. The Align 3A regulators have been known to fail. I am now using the newer Align 2in1 regulator for the REX600. Its really convenient especially not having to bring a glow starter! Just push a button and rev up the shaft starter.

Cheers,
Owen

Hi ,

The 5A UBEC 5v/6v and 8A UBEC 5v/6v is a switch-mode DC-DC regulator. Compare with Align which is Linear mode UBEC can expect cut off or loss of controll due to over-heat problem. That why the new Align 6A comes with heatsink.

Here are the manual from Himodel which originally from Hobbywing.




I like post from DKSHEMA from Runryder mentioning Linear using resistor component compare with switch mode using coil if I not mistaken.

Please check this link from Runryder for everybody

I almost order Align 6A 2 in 1 voltage regulator combo from Radiocontrol-sport. But Ken won't recomend to me because he experienced glitch and lost signal.

Your'e right, S9402 running 6V is 8Kg / 0.10 sec.

You try Align blade or pinjam from Aziz , you will see your heli will more responsive climb up and responsive cyclic control Very Happy .

Its interesting to see that as an observation.. in Runryder, the problems with the Align 2in1 are essentially to do with the wiring being stressed and not properly dampened. Glitches should not be a problem for Linear Regulator. But you (ken) may be right as i have experienced a glitch on my TREX600 last time... and i found that strange... as i have so far never experienced that with my Titan. Maybe i should stick with Duralite... it has never dissapointed me so far. Only thing is that its very basic i.e. no voltage indicator lights... no glo starter.... hmmmm... but at least no crash eh... hehehehe

True that its a waste of energy as the voltage reduction component is a resistor, but what is equally important is cooling air. If u place the regulator where there is limited airflow, then problems are known to arise. Also if u r installing low amp linear regulator, and overloading with high amp draw digital servo's, then it will also overheat and go into thermal shutdown. Matching is very important i.e. checking the loading of your flight equipment.

Switched regulators although don't have issues with heat, tend to have problem with glitching if not placed or filtered properly. High end regulators like Duralite & Powerbox (as used by large scale aerobatics, gassers and turbine jets) are all linear regulators due to that issue.

Hi,

Duralite are the best but the the lipo batt are almost heavy as Ncd 1500 4.8v cell or maybe abit heavy I think. And yes for the new switch UBEC, it had been warn to install far from receiver. But the prvious version I did put it ontop of my receiver without any problem. I hope no problem with the new switch UBEC.

For the SGP Reactor, no chance..... to expensive lol!

Duralite can use Li-Po 2s. I'm using it with my 2s Li-Po 2s1p 2100mah on the 90SE

Oic, if I' not mistaken Chris using Duralite battery on his Raptor 50, so can be use different batt. How much you bought it?

Duralite regulator with heavy duty switch... can get from Mockingbird RC between $90-110.

http://www.mockingbirdrc.com/store/index.php?cPath=28&osCsid=4706d201e3f4374cb830005313b5ae33

This is without the battery.... which is what we want. Usually Duralite will package with Lithium Manganese battery which is more durable but heavier.

Cheers,
Owen

wow....guys ...seem to be alot of issues here with the regulator...!!!!!

I will try out the align blades and see what happen next...

Good luck with the turbine project Owen...!!!!

Bah bila main di KB...G29 x bom storabe area..and teach us some 3d's....??? kikikikik...

Axen,

Seems like G29 is not any more allowed for Rc flyers, so we move to Sekolah Lumut, so just send sms la if you intend to join us nanti...

By the way ... your 3d's was awesome mmmmaaannnn...sick ... insane...live 3d's I have ever seen....you set the standard for the KB ians ..mmmmaaaannnnn....cooolllll....cant wait to have you around the Wink next time... afro

Hi Atan_126,

Thanks for the info. I think I know where is Sekolah Lumut nearer we flew before with arzc.

For my flying, is not so much lah coz I do some mistake too..... sometimes hehehe

Anyway, some of my friends at Bandar flew their heli more better than me
