4S in Buggies

[DRIFT_BUGGY]

Seems like most common lipo battery used in a Buggy is 4S. Is that because of weight? I was looking at running a 2.5D 1512 in a Buggy on 5S

depends on the application...if you are racing especially in a shorter track you dont have much of an oppertunity to go WOT

I'm running a 1512 2.5d/f in my 8ight on 5s. The Maxamps 4000mah 5s is a perfect fit, not too heavy and gives killer power with long runtimes and manageable heat. I had to add a heatsink to my Quark but no problems since. Best car I've tried yet!

What gearing where you running?
I was looking at running the Thunder Power eXtreme V2 5S 5000mah

What kind of run time do you get with that set up?

My track is large enough, front straight is pretty long

4s is often plenty to surpass the nitros in both acceleration and top speed. I'm running 4s with a Neu 1512 2.5D/F in my Hyper 8, geared for ~45mph, and everything (MM + batts + motor) run at very acceptable temps.

What gearing do you use in the Hyper 8? To get the 8ight to go 45mph on a 1512 2.5D & 4S would require a 17T-18T Pinion and 46T Spur. On 5S would require a 14T pinion. What run time you get?
How much extra run time would I get on using a 5S 5000 instead of a 4S 5000?

I thought that 4S was kinda "the standard" because that was what ROAR (or whoever makes the rules) decided was the fairest max LiPo cell count to keep things even with nitros.

I had no idea that ROAR or any racing organization made a ruling on 1/8 electric.

You may be right. Thought I had remembered reading something else somewhere though.

Found this:

but seems to be about 1/10 scale.

18t pinion with Kyosho 46t plastic spur. Run time when I was using a 14t pinion and 4s 4800mah was 15-20mins depending on the track. I've only run one pack with the 18t pinion, but I would guess ~15mins of runtime.

I'm running 14/46. I get 20 minutes of hard running or close to 30 min of my usual bashing around. I occasionally run at a local track and I never get more than 1/2 throttle into it, way too fast to let loose but it drifts like a champ on any surface.

When I get my Mamba Monster I'm going to run 6s and about 16/46 in my CR. I just bought a nice TP Extreme 6s 3850 but I probably won't get it until I get the MM because the guy I bought it from lives in Canada. Oh well, I guess the timing will work out well though right at the same time.

I'll keep you guys posted on my build thread as soon as I get that stuff in.

I run direct drive on my buggy with 5s, like stated above it depends on how much speed you need for what ur doin. i personally am a speed demon and just wanted the 5s :D my car would have don fine on 4
