Do different brands of digital servos have different draws on the rx pack? Are some known for pulling down the rx pack hard and others are less hungry?

for sure... more power, more amps... i know i used to run a JR 8711, and that thing killed packs quick.

But what about if the servos have close to the same performance? speed and torque.

some servos take more power to perform the same tasks..you need to check their draw rate...its listed on the package or the spec sheet..its all according to the motor the servo uses

Ah, thanks, thats what I was after I guess! I've just been running these analog Airtronics so long 94357+94358, I'm nervous about digital. I just returned my Futaba bls 451+452 because I am thinking high draw servos arent for me. I have fun running A LOT when I am at the track and stopping to go charge my rx pack for 45 min or whatever would ball me up.

So how about buying a second receiver pack then?
Since i don't like recharging at the track either, I've got four...

YES, there is a big difference between models and makes. Specs are published by the manufacturer that will give you ballpark figures. And 5 cell receiver packs will go flat quicker than 4 cell (it sounds counter-intuitive, but it's true).
