soldering is actually really simple. you just connect your wires together, then melt the solder with a soldering iron. the solder flows onto the wires and your done.
there is some cheap soldering irons at radioshack you can get started with. soldering tutorials can be found on google.
Eryn - How many total Amperes of current will this setup of yours be drawing? More important than the actual voltage the current rating becomes important. You could go cheap and get something which may not supply enough current only to discover that you needed something which needs to provide more current. I know for sure this one will give a good current output ... Turnigy 5A (8-26v) SBEC for Lipo (USA Warehouse) PRODUCT ID: SBEC-26V . I have this one and so far it has powered whatever I've thrown at it.
kenneth - Is this thing physically very large or just about what size is it? On a previous purchase I got this one ... Turnigy 5A (8-26v) SBEC for Lipo (USA Warehouse) PRODUCT ID: SBEC-26V ... which looks similar to this one and I was somewhat displeased by it size ( kind of large ).
Donald - Thanks for letting me know. For some reason(s) or another there isn't a Best Answer tab under your reply so that I can click on it and give you credit for your reply. Otherwise I would have done it for you.
Donald - I received mine and here are the approximate measurements: 45mm ( 1.7 inch ) long, 23mm ( 0.9 inch ) wide, 11mm ( 0.4 inch ) thick with buzzer height and 5mm ( 0.2 inch ) thick without buzzer height.
Peter - I've found that for the 3A ( 4A max ) current load this UBEC is rated at the female JST connector works best. Look at these ... Female JST battery pigtail 12cm length (10pcs/bag) (US Warehouse) PRODUCT ID: AM-9017A ... and also this for power tapping situations ... XT60 - JST Male In-line Power Adapter (USA warehouse) PRODUCT ID: XT60-JSTM
Bought 2 of these to try out on a quad setup I'm building. Also used 1 on a foamy that I added flaps too and needed a little extra juice to run the extra servos. Very satisfied. I especially like the buzzer for the quad setup. It's actually pretty loud and can hear it from a good distance. Great price. Just me learning. :)
