Default Lipos for reciever packs?

Hey boys... Does anyone use 2cell lipos for receiver packs ? I want to run one with my spectrum sr3300t reciever in my savage. Would I need a bec to step the voltage down to six volts or would the receiver do that for me? Would I be able to run turnigy high voltage servos with this and not have a bec? Also do lipos make good reciever packs?

Your receiver can handle it, your servo choice might not be able to handle it.
Alot of people are running lipo receiver packs.
I run the Protek in the buggy and the Reedy in the truggy. I still use voltage regulator as my servos are not publicly advertised to handle 7.4volts. I have used them at 7.4 for one race weekend and there were no issues.

Default re lipo receiver packs

ive been using 2s lipo receiver packs since last season without a voltage regulator without any problems.

using the trusty hitec 5955 tg for steering and its still going strong.

i was running a jr high voltage steering servo but the gears in the servo crapped out early last season so i put in the hi tec 5955 tg in its place and no problems. i also ran this servo in my truggy for crcrc and motorama .

imo hi tec servos are the most reliable and longest lasting servos you can buy.

A 900mAh pack will give you about 40 min of run time and a 2000 mAh pack will give you about 2 hrs. Depends on how much you wanna spend.

I run the Losi 2000mah with a Specktrum and Hitec 7950s. I've been ruined for life I think.

Yeah I used the Losi 2000mah through a SR3300T receiver and use 2 Hitec 7955 servos and it works great.

1600 Mah is good for the whole day. I run a 2100 in Truggy and will run a 2300 in buggy. I balance between heats, not needed, for reassurance.. I'ld hate to have one dump on me in a Main..

After my last race weekend I put 1723 into the pack I didnt top it at all through the day but I'll probably start doing so now.

How long was your main and how long did you practice? Both of those can make a world of difference.. And is one reason I top them off between rounds..

A number of practice runs (3-4 tanks, ~9 minutes each), 2 x 5 minute qualifiers, a 1 x 10 minute main. If I had to guess, 50 minutes of driving time.

90 minutes would be about right.. I've gone that long before, with a charge..
