Aha! The link worked fine and got me directly into the manual. Evidently Hobby King does not have on staff a proofreader who is a native English speaker. Nonetheless, the instructions seem clear enough. Not sure what to make of "multi use crocodile pin." Anyway, it seems clear now that the red and black leads on the right side of the unit are for the DC power supply. Mine has what looks like 3mm male pins on the ends of the power leads. I guess those will plug into a power supply, maybe with an adaptor. One curious feature is the glow igniter lead, apparently for those electric flyers who have not made the switch completely from glow. Nice that it also charges RC tx and rx batteries.
