If its electric, then you'll probably find the ESC puts out a fair amount of noise and transients. It could be that the input stage didn't like this very much, some protection may have been needed (e.g. transient supressors, filters etc)</p>

It gets hot when converting 12V to 3.3V for a digicam, so no shrink wrapping. It's designed to be soldered on a board like a BGA, with airflow under the inductor. It needs odd resistors to determine the output voltage & can't use resistor dividers like the LM317. Sparkfun doesn't have the odd resistors, but other places do, in addition to having the DC-DC converter.</p>

Pins instead of solder pads would be nice though, especially at 0.1" spacing. I'm using some 2 amp DC-DC converters for a LED array and the pins are a little off (I have to drill out the protoboard a bit).</p>
