All depends on the gearing and weight. If you read reviews, guys are running them in stampede's and getting great results. Plus, if he's concerned about too much power breaking the driveline, when geared down it'll be plenty tame.

I know in my stadium truck it was faster in straights than guys running much more expensive sensored combos, and I was getting more run time too.

How come these 3s sky lipos are smaller in size than the Turnigy lipos sold on HK? Im thinking about ordering this one....I wont have to modify my battery tray...should fit just fine, right?...I'm glad i found this website...reviews are good and these 3s lipos are much smaller than the 3s turnigy lipos!

Anybody knows the stock battery size that shipped with the rs4 mt? Or the exact measurement of the battery tray? this one shows to be 136mm which is like 5.5 inches.

Looks right, but I'd have to get off my lazy rear and measure to be sure, lol

Why are you looking at 3s packs?? You'll get PLENTY of speed out of 2s packs...

Besides damage from crash what other risks are there?? The ESC is up to it and so is the motor...then why not 3s??

More heat, the motor will wear out faster, less run time.

Brushless on a 3s will likely ruin the drivetrain, just something to keep in mind.

Power supply you should look at something higher wattage than what your charger is capable of putting out. But the the required Voltage.
My laptop power supply is 19V 3.4A 65W, But the charger has an input of 11-17V input.
So i have to get a charger with higher wattage than the charger....but what about the volts i didnt get that part quite well??? It has the to be the same voltage? exactly the same or a little higher or lower is okay? And your laptop charger is 19V but charger input is 11-17V...so does that mean it will work or it wont work?

the voltage pushes the current if there is little current to push it's not going to be very good. the higher the voltage the better the push. but at anything higher than the 3.4A would overheat a lap top psu. you might be able to run 18V psu but i'd keep the voltage at 15-17V.

Do you guys think its a faulty buzzer?

Ran into another problem...while running the rs4 after about good 8 minutes the car started to slow down...i pulled the battery out and let it sit for about 20 mins...then i plugged it into the charger and after the charger scanned the battery on top right it says "R: 2ser" and top right says "S: 3ser"

What is that supposed to mean?

Sounds like you have the charger on the wrong setting. If it's a 3s pack, you have the charger on 2s mode.

You should be getting MUCH more than 8 minutes on a charge, my stadium truck gets 30 minutes on about half a 5000mah pack.
