Guys charging up reciever battery on hellfire for first time. I noticed where the reciever battery plugs into truck there are two plugins, what is the other plug in for? How often do I have to charge reciever battery? Is the other plug in for a different type of battery? please help.

one connects to the pack and the other is left outside the box so charging is easier?

Are you referring to the two plug inputs on the reciever, next to the steering and throttle servo wires?. If so, the extra plug in the reciever is for an auxillary third channel. The RTR Hellfire ships with the same three channel AM radio system that the Savage trucks use, so you could conceivably take this radio and put it into another vehicle that uses a third channel.

As for the length of time needed for the battery, I'm not aware of what the type or capacity is of the reciever pack. Check the manual, or with HPI. Their customer service group is the best in the business and I believe they are open on the weekends. I use the 1600man Orion Marathon packs.

Kappa... Nice to see you Buddy!!!!

Still roamin' the ether. I've kinda decided to take a short beak from the other place and cool off a bit.
