From browsing through the forums, it seems many people have tried a 6S setup in their 1/8 buggies/truggies.

To the people that have done it...

Are you still running 6S?
Why did you switch back to 4S (if you did)?
Lessons learned? Advice?

Thinking about trying it out this weekend, but looking for a little more real world feedback.

Thanks

A higher voltage setup is ALWAYS more efficient that a similar power low voltage setup.


A good example of this is powerlines... transmitting 120v from the plant over 100s of miles of wire at the amperage required would need wires the size of basketballs(or larger) when they can raise the voltage and use smaller wires...

Don't be stupid and use the same motor on 4s that you do on 6s, they need to be matched to your pack. Generally 1400kv for 6s and 1700-1900kv on 4s

Btw my buggy and truggy I've run 4,5 & 6s setups.. for the last year or so I've switched all of them back to 4s setups for several reasons...

Many tracks are loosely based on roar rules (4s only) and I setup both my truggy and buggy to run on my hyperion 4s packs. I use 5500's in both vehicles and 6500's in my truggy. If I ever needed to I can use the larger packs as in the buggy as well (real long mains). If you have your motor at the right RPM for your setup (~30k) the lipo weight(grams) per total run time will be pretty similar for 4-6s setups.. 6s is more effecient so you can have less mAH to do the same job, but keep in mind you have two extra cells that add to the weight. When it's said and done it's pretty equal on properly setup vehicles with in a couple laps on the race track, but at least w/ 4s you don't have to worry about any rules if you hit different tracks. It did help I got GREAT prices on my 4s hyperions as well you just can't these packs performance per/$ iMO.

I much prefer the higher voltage as I find my packs and ESC definitely run cooler. Motor temps tend to stay the same regardless of voltage in my experience. I do get better run times as well.

With a buggy, I don't think you need more than 4s, but 5s and 6s are better imho. A couple of years ago, there was a pretty significant difference, but the newer 4s packs seem to be capable of pushing the cars just fine these days.

With a truggy, 5s and 6s is definitely more appropriate.

As Whizrac said, properly match the motor to the voltage or else going up in voltage is just wasted energy.

1400kv = 5s & 6s
1500-1700 = 5s
1700 - 2200 = 4s
2600 - 3300 = 3s

You can use the 2200 kv motor on 6s. Just make sure you gear it down. You'll be using a 12-13T pinion on an RC8Be. As long as you can get an appropriate sized pinion,go at it

I can go on a homicidal massacre across the country... That doesn't mean I should...


about the 4s/track rules/etc...

I find that if a track allows soft packs, they generally don't have an issue with 6s, as long as your not being stupid with them/motors... If they demand hardcase, your usually SOL...

I've done it with my RC8TE truggy and absolutely LOVE it. I am capable of making 25-30 minute mains depending on the track and overall the performance is great and it's very efficient. On average, per 6 minute qualifier I use only 1500mah.

LOL!

I do have a 1400kv ready to pair up with 6s if I go that way.

Yes, I run 6S together with nitro's at local club races.
I'll never switch back to 4S.
Reason: same battery weight (4S 5000mAh ~ 6S 3300mAh) with comparable runtime (15:30 min).
The feel of a 6S 1350Kv is much smoother than a 4S 2200kv, and slightly more power reserve.

Running 6s with a Tekin RX8 and T8 1400kv and absolutely love it. Low temps and great runtime. Put back around 850mah after 5 min qualifiers with ESC around 100 degrees and motor at 120. I think I put back around 1150-1200 mah (give or take a bit cant remember for sure) after a 8 min main this weekend. Using a 3000mah Turnigy pack and u cant beat it for the money. Another guy runs the same set up and batteries and has for a while and he loves it also. Like others have said- the 4s limitation that some tracks have is a the limiting factor. Luckily- where I run there are no battery limit rules on Ebuggy.

Thanks for the input.

I already have a RX8, Tekin 1400kv and some 3s 3800 batteries from my airplanes. Caster runs a saddle config, so 2 x 3s 3800.

They also make hard case 3s batteries that I'm thinking about. Will probably just use what I have and decide from there.

As long as you can find a pinion small enough, you can safely go to 2500 kv on 6S. That will still keep the motor within the max allowable RPM. Going up in voltage is NEVER a waste in energy, as long as you can still go wide open and not be too fast.

.. How about going to 12S 10,000 ?

Thanks for posting that up, now I want to go fly.

I watched most of your videos when I started getting interested in 3D, awesome stuff!!!
I still go back and watch for tips every so often.

i used to race 6s on 1350-1600kv motor on my truggies n 4s on my buggies.

but to make things simple i change all to 4s so i can use the same batts for all cars.

we have a ep class so i dont need long run time. just 10mins per main.

besides 6s is more expensive than 4s if based on the same mah n C rating.

Iam running my Buggy on 5s 3600 mah pack and i Love motor temps are never over 140 it has plenty of power and i can run 10 minute mains with out a issue.

Iam using a Tekin rx8 on a T8 1900kv motor
