If you get a 5 cell reveiver pack, you'll be running them at 6v. That's what most of us do here.

What radio are you running? If it's a JR, you're only getting 4.8 volts to the
servos unless you put the battery plug into one of the channel slots.

I can explain in more detail if needed....

I run a JR (on the savage). I'd like to request addition detail.

JR's use a resistor (correct me if I'm wrong) on the batt terminal to reduce voltage to prevent a short.
Thats what i've heard in the past.

If you ARE NOT using channel 3 on your receiver
plug the battery pack in there.

---OR---

If you ARE using channel 3, plug a y-adapter into channel 3
and then plug the battery and servo into the y-adapter.
You can use the Traxxas y-adapter part #2046. It's only
about 4 bucks and it's very sturdy.

Thanks TechRC for the info. I did notice they picked up more speed. I put the FOC on the revo at the same time. No more christmas lights under the hood

Hey, your setup was On at the end of your main. I think you piched up 2 secs a lap plus much more consistant whithout those darn shocks...

Great time and great race

That's the first I've heard of that, maybe I should have read the owners manuals better...

Looks like I'm going to be picking up a "Y" connector for the LST, and switching the battery location on the Savage. Hopefully this will help pick up some steering...

Thanks Tech....

What receiver are you using? I just verified what I told you with a couple of
my JR RS300 receivers. It was ~5volts going to the servos with the
plug in the battery slot and ~6volts going to the servos with the plug
in the channel 3 slot.

ok i checked the voltage on the rs300 and there is a 1 volt diffrence if u run power to the battery connection vs the 3rd channel. Earlyer today i swaped out the stock servos on the revo and now im using 1 hitec. So i right away used the spliter on the 3rd channel so i can run a transponder when i get one So tech is right unless u have the 310 reciever which comes with the pro xs3 ure loosing 1 volt!

They must has re-designed the RS310. That's a good thing.
The reason I discovered the 1 volt drop was because it
messes with the Optidrive on the Revo making it think the
receiver battery it dead all the time.

ahh ok thats why kevins revo light was blinking red then...i ditched the opti drive when i put the rs310 in since i dont use reverse (servo went out) but i figure thats best anyway for racing.
