The Turnigy Heli-UBEC is a great option for models requiring up to 5A continuous current and 5V/6V output. The output voltage is easily selectable by switch. The input side features a JST plug pre-installed, while the output side uses a JR style plug for use with any receiver.
The Heli-UBEC is compact in size and lightweight, making it ideal for mounting conveniently on your helicopter frame without taking up much space.
Features: • Compact in size • 5V/6V selectable output • 5A continuous output current (7.5A burst) • 6~16V input range allowing for use with 2~4S lipoly battery packs
It is really annoying to read stupid answers by people who don't understand the question, i.e., don't know what a switching bec is. Atan #1, to answer your question, this is probably a switching bec as indicated by the attached ferrite noise suppression coil on the output lead which is only required on a switching bec to filter high frequencies generated by the switching circuitry. Another clue is the 16V input limit. A linear bec would have to dissipate 30 watts or more to output 5-6 volts at 5 Amps with 16 volts input, which is not likely possible in a package this size.
Not for 2 cell life, bit OK for 3 cell life. It will need a minimum of around a volt 'dropout' between the supply and the output. Hence it will not deliver 6v out for 6v in! Probably OK for 5v out/6v in (sorry I have not tested) and 7v in and 6v out. Mike
