Would it be a good move to solder 3.5mm bullet connectors and plug this in to the power distribution board?
 v_max 3743 points
The best practise is to connect all power connections at one point (star type as opposite to tree type wiring). So connecting to power distribution board is a good place.. Other thought. This bec is low current .. so you do not need 3.5mm bullets which is ok up to 30-40A ... you may smaller ones like 2mm to save weight.

Whats the difference between the two UBEC's (this one and HKU5) besides the name? Thanks
 Finnius 172 points
The X5 (X5UBEC) looks identical, any difference?
 v_max 3743 points
This one is wrapped into metallised tape under heatshrink to reduce switching bec noise
 Finnius 172 points
Thanks. So the tape reduces noise from this device, to minimize interference with other devices?

exactly..

I connect the input of ubec and output of battery in a wrong way... which mean red connected to black and black connected to red. Suddenly, it sparked and now it is broken. It doesn't work at all. It's better than exploding :D

Wtf the elco just exploded! Good thing it was during testing! Damn that one got my heart going xD Anyone els had this happen?
 v_max 3743 points
electrolithic capacitors excelently explode with reversed polarity... Wasn't it your mistake?...

I used it before and is not reliable in combination with my kk2.1 keeps restarting.. So I used it for testing some LEDs and BANG! And it said it has built-in reverse *polarity protection..

HK is pretty fair, id send them an email before you give up on your firecracker.

Purchased three of these for ignition voltage regulator duty in my large scale gas planes, when paired up with the turnigy 2100 Lipo receiver pack, you can run an engine all day versus the 4 cell NiMH packs. Working great in my planes, the 3A version works great too, but is a little longer and slightly heavier, but cost less. Next order, I will order more for spares for future projects.
