Review on WINGONEER XL4005 Adjustable Module Converter by Paul Barnes

Use as an inexpensive UBEC on RC cars. Standard ESCs usually have fairly weak BECs built in, and powerful servos can easily overload them and cause glitches. Dedicated UBECs from major RC vendors are not particularly cheap. These DC jacks allow me to solder wires directly to the liposuction. Adjust the voltage with a screw (I use 6V or 7.4V depending on the capabilities of the servo). You will need a multimeter for this step because without measuring you cannot know what voltage is set. I then connect the output side directly to the +/- servo, which gets a bit ugly as I have to cut the servo wire, with the signal wire going to RX and the power going to that converter. This allows the onboard ESC to power the rest of the electronics and the full 5 amps available here to power the servo. However, you can plug it into the servo connector and connect it to an open port on your receiver, but if you do this make sure you disconnect the power wire from the ESC servo connector and heat shrink it so it doesn't jump. shorten things. Finally, I smeared the screw with hot glue so it couldn't accidentally change tension, and then wrapped a large piece of heat shrink tubing around the entire board. They work great for me, it's a bit of work but I can get a 5 for significantly less than a well known brand's external BEC.
