I just purchased a HS-7955TG for a steering servo and a HS-7965MG for a throttle/brake servo on a HPI Hellfire SS.

I don't know much about batteries and I can't find good info anywhere, so I'm not sure what to get for a rx battery pack.

I know I need a 6.0V pack as the servos won't handle more voltage and nimh is recommended over NiCd, but what capacity should I get? The Hellfire RTR comes with a 1200mAh pack, but I'm concerned that wouldn't have enough amperage for these servos. Am I correct that the capacity is a factor in how many amps the servos can pull?

Not sure if it matters, but my receiver is Spektrum DX3R.

Any help would be appreciated!

By the way, do you think I made a good choice in servos?

Thanks!
