00whynot I believe they need the red wire, since they apparently make a profound futile beeping noise and refuse to allow any power through them if they don't have their 5v power supply (since they're not BESCs).

Will this power 6 ESCs, a MultiWii and a receiver? I know the GPS uses >50mA, but I have no idea what the ESCs will use. These are the ESCs, does anybody know how much they draw? /hobbyking/store/__7339__Hobbyking_SS_Series_
50_60A_ESC.html Thank
you.
 00whynot 2 points
I believe it will. The esc's should pull there power from the battery it's self. When you hook them up you have to remove the red wire from the centre of the connector on each esc. All they need is a signal wire and the ground wire.

I am putting 7.2v into the receiver for the sailwinch but the servo can only handle 6v. Can I put this device between the receiver and the 6v servo?
 Mav75 76 points
Yes, just put a connector on the in wires to plug into any reciever channel. You should use a three wire connecter and put the servo signal wire on it too, so you can plug it all into channel 1, or whatever channel your servo is on. For the out wires on the bec, connect those directly to the servo and - wires.

Thanks Mav, this seems the simplest way to me but so many others have different ideas. Why not keep it simple?!

Do UBECs such as this one have a low voltage cutoff to protect lithium cells?

some do but not this one..

Those servos pull a good 2A if you just run them back and forth and will stall at around 4A so you need more than this

can this UBEC power two HK15178 Analog Servo 10g / 1.4kg / 0.09s ?
 Robert 21 points
Yes in can. No issues.

Hey guys,I just got one in mail.probably a dumb question,but do I need another battery for this or does it connect to main battery?and if so,how? Do they make a splitter or something?
 RevJVegas 70 points
Either or actually. You can use the same battery or a separate one. I don't know if they sell a splitter to meet your need, but if you have soldering skills, it is not that hard to make your own. I'm using mine to power a portable DVR that needs 6v, so I put a connector on it to mate with my 3s lipos.

hallo wird einfach an deine versorger akku angehängt gruess
 Benjamin 11 points
using mine in-line between lipo and an R/x. not using a seperate battery.
 rccfanatic 34 points
I solder it to the battery plug along with the esc's battery wire.

hey guys... i have one of these and was wondering if i can connect it to a 12volt car battery and use the output for my receiver. will that be okay?...has anyone tried anything like this? reply will be appreciated thanks!

Olá, sem problemas, respite sempre o limite máximo de voltagem. Bom divertimento.
 blinkvc 12 points
Hi !! Yes you can use your battery of 12 volts for this UBEC. Good Lucky!

Hi, could i fit a Turnigy MG90S Metal Gear Servo 1.8kg / 13.4g / 0.10sec with this Bec?? is too much voltage???
 Lucio 10 points
You can use it perfectly, the voltage is 6 v and your servos works well with this voltage

So now that you folks have duked it out over the weight and shipping cost how does it work?!? Does it perform as it states it will or is this a pass???
pudytat  1342 points - 6/13/2011
 
Why is the shipping weight 65 grams when the item only weighs 9.2 grams? The packaging weighs 56 grams.??? If so, change the packaging!
 tompleh 48 points
i agree on that..
BEST ANSWER CREDIT AWARDED
 boingk 265 points
I also agree. Unfortunately this is common among HobbyKing items - an 80g flat-pack balsa kit weighing 500g , 20g batteries weighing 70g, 5g servos weighing 30g... the list continues.

We accept that some items might be akwardly sized and thus need more postage charge, like rolls of covering film, but come on HK just tell us why objects like this weigh so much?
 MrRCFlyyer 744 points
Nah You are half correct. You see you want to save on shipping but if the packaging didn't weigh 56grams it means when it arrives at your doorstep, the ubec would be nothing but just cribbles of circuit boards and FETS. Its all about Making the Right Decision.
 pudytat 1342 points
HK ships a LOT of circuit board stuff in nothing but a plastic baggy all the time. Packaging for this little thing is NOT 56 grams. Unless it is a solid wooden box that they ship it in maybe?
 tompleh 48 points
why is it the package are 7 x BEC itself ?? total weight is almost the same as single 20-30 Amps ESC..
 Jackrr 224 points
I agree with pudytat. There needs to be some protective packaging (just got a turnigy esc 18a, included a piece of paper and esd protection - nothing more). There should a "small box" that you always need to order (and a medium, a big box for bigger items), weighing maybe 20g, and this item should be packed lighter in the system, so that you get maybe 3-5 in a 100g order.
 MrRCFlyyer 744 points
Mates, there goes to show that you can't complain about the packing thats for sure. Making the right choice of not complain or whining in some cases might save you money spent on the product ! It's all about CHOICES ! Cheers.
 Mav75 76 points
I sorta agree here, look at PRODUCT ID: HKUBEC3A 11.5g real, 29g shipped. How's that work?

My theory is that it comes in a nice box. When I got my bluebird servo, I was not expecting such a great package that it came in because it was not pictured. Just something to think about.
 xaviere 236 points
Who cares what the shipping costs are,I'm glad to get the products at a reduced price. I dont have to spend money on fuel to go to my LHS etc to get them. Also, at HK you have the ability to
find out more about the product and others experiences with that item, something you always dont get at your hobby shop "cause the fellow behind the counter only sees the $$$$ in the deal. Not that I have anything against the LHS fellow, but he is there to make money. I bet if you add up all the savings you have made buying at HK compared to LHS you would stop quibling about peanuts. Cheers from "THE MAN FROM THE LAND DOWN UNDER".
 MrRCFlyyer 744 points
Verdict to the cost, Case closed. Or not
 pudytat 1342 points
OK, cost at 3.50 shipping price with only 20 grams total shipping weight or 9.50 shipping cost with 65 grams shipping weight. Why is it that all the other Hong Kong website offer free shipping on their items and HK doesn't???
 MrRCFlyyer 744 points
Sure pudytat if you do not have the money to pay why shop at HobbyKing ? HobbyKing is the place for cheap products and cheap shipping.Anthony had worked hard getting deals and trying to keep shipping costs down and why is HobbyKing special because they take their products seriously.Now you are just paying for one little BEC and you are making such a fuss, why don't you just buy things in a large scale and save on shipping or go to your local hobby shop thats all.
 pudytat 1342 points
"why don't you just buy things in a large scale and save on shipping".... You don't seem to get it do you. With inflated shipping weights, it makes the shipping cost even more expensive. Yes, I agree that there are cheap items here (a lot are cheap quality too). But when you add in the shipping, it is on par with more expensive sites or LHS. So if you order more, it is only going to cost you more with the added shipping costs (nothing saved in bulk). The tanks that they sell here are an example, they are almost half price, but their shipping is more than they are, putting the price even with sights with free shipping.
 MrRCFlyyer 744 points
But talking about buying from other hongkong or china website, Do You trust them and do they trust you . The end game is not about the shipping or product cost, it is about the PRODUCT THAT YOU'VE BOUGHT LANDING WITHOUT DAMAGE AT YOUR DOORSTEP.So Mates, Making the right decision could bring SUCCESS but one wrong choice leads to a DOWNFALL.And you talking about "The tanks that they sell here are an example, they are almost half price, but their shipping is more than they are, putting the price even with sights with free shipping" , even though other sites offer free shipping , will the Product or in this case tanks arrive at your doorstep unharmed and glossy as new ?
Make the right choice and Adapt to the right mindset mate.
 pudytat 1342 points
The other sites ship with the exact same shipping company from HK, and in the states and use the same type of packaging. I have had parts shipped from Hobby King that were in nothing but a paper envelope before, but I was charged for 20 extra grams for shipping and there was no extra protection in the packaging at all. With your closed minded ranting, you are MISSING THE POINT. Unless you can answer the question that is asked, don't post. I asked a SIMPLE question "Why is the shipping weight 65 grams when the item only weighs 9.2 grams?" but you do nothing but rant about choices. If you want to rant, go to the forums.
 MrRCFlyyer 744 points
Whoa dude you need a chill-pill mate alright back to the question: Why is the shipping weight 65 grams when the item only weighs 9.2 grams?
My Answer: 9.1grams for the UBEC, 8 grams for the Envelope or 22grams for the Small box & 47.8grams for packing the UBEC in a nice glossy zip-tight bag(By Envelope) or 33.9grams for zip-tight bag and the protective packaging(By Parcel)
 MrRCFlyyer 744 points
wHOA DUDE you seriously need a chill-pill mate.
Maybe if you purchase one of these you may find out why it is just 65Grams please don't tell me that you are just gonna buy this product only and pay a small amount of money just for this product. Utilise your shipping by adding this to your cart HobbyKing's cart system Alerts you your leftover shipping weight and you could scroll down to find another product that fits into the shipping weight perfectly to fully utlise the shipping cost SIMPLE!
 tompleh 48 points
EVERYBODY..cool down..lets just wait anyone that bought this BEC and make review about the package..if the extra weight are really for the great package so its solve..but if the extra weight comes to nothing or at least cheap medicine plastic bag (like HK401B gyro) so you can figure it out by yourself hehehe..anyway, this BEC is value for money indeed, but lets wait for the review..

Nice, small, strong, cheap.
Uses MP2307, you may find this chip in other modules as well.
Can be easily modified to support a "low = off" input, you just need to open the shrink and add a wire.
Voltage may be modified too, but you have to deal with 0603 SMDs...
Excellent value for the price.
