Hobbywing 5V/6V 3A Switch-Mode Ultimate BEC (UBEC)

Pros: This small little DC/DC converter solves the power loss/heat problems associated with a resistor or series pass type voltage regulator. My use is to drop a 12V battery on my scooter down to about 4V to light a white LED for use as the headlight. My current plan is to use the DX R2 module (350 mA) for the light. In tests, the R2 gets HOT (even at the 5V Hobbywing output). With no heat sink, it gets hot enough to cut in the thermal cutout (LED flashes). Meanwhile, the Hobbywing unit just barely gets warm! I ended up putting a diode in series with the R2 module and it still gets hot but, not hot enough to cut out (although I'll probably need more heat sinking in the scooter light assembly). The Hobbywing is extremely simple to hook up and has a little red indicator LED for operation. It's small and seems to be well-built.

Cons: The only con I can think of is that there's limited mounting facilities for the unit. The whole thing is enclosed in a plastic sleeve. Oh, yeah, and it's a good hobby shop price but, maybe a little expensive for a DX item.

Other: To drop some voltage without the heat or power loss, this is a great solution.

Pros: Very stable UBEC, it works great and the output is stable even under high load. I'm using it in some hobby projects and its a great tool to have a stable output.

Cons: - gets a bit hot under load
- cables connected are a bit small, should be thikker
- a better connector would be cool and handy
- some sort of mounting holes would e usefull, it is not easy to mount it somewhere. I had to use some sort of clips to fixate it on my projects

Other: For its price its a good buy, i use it in 3 of my projects and i'm verry happy with it. If i buy something similar here in BE i pay 3 times the price

Pros: its my 2nd time buying this item, since then, the price dropped :)
I used the original to regulate servo ampere and volts. now I bought this 2nd one to connect with the lipo upgrade in my futaba 6EXA and opened the radio to boost it using an SMA converter and sku.19616 because it asks for non-12V supply.

Cons: none!
really, none!

Other: if you need a UBEC, i would consider this!

Pros: Does EXACTLY what it promises. * It is very, very tiny and lightweight * It performs well, the voltage is 5.20V * It is easy to use

Cons: None that I can think of. Well, my problem is that I do not have any compatible connector for 5V output but that is not the fault of the product, just my hobby room :) One thing worth mentioning is that it will not do your laundry or polish your shoes. It will only convert a higher DC voltage to 5V/6V DC :)

Other: Good product, absolutely worth the price.

Pros: -Small and lightweight - 5.18v output - good quality - easy to install -

Cons: polarity was reversed!!! I had to check with a voltmeter, but the voltage was definitely reversed... good thing my equipment had a reverse polarity protection!

Other: get it, but if you have a sensitive receiver or whatever else you need to power be careful. Nothing else to say really, works (somewhat) as advertized

Pros: - Small, you can pretty much tuck it away in any corner. - Quite powerful, can handle a strong single servo with ease, good for 1/10th scale electric buggies. Will probably handle two strong servos as well. - Cheap as chips... Comparable items go for double or more.

Cons: - It's a necessary evil... If only the internal BEC of the electronic speed controller was powerful enough, this UBEC wouldn't be necessary. Ironically, this is not a con of *this* product, but of the product that this item is supposed to support.

Other: I already bought a second one for another buggy, and it's likely I will buy more in the future.
