1/8 buggies using 2S Lipos???

I want to know more, the only reason I don't have a 1/8 is because I like simple 2S. I have a pretty big motor. It's a Tacon 3500KV and I have a 60amp esc.

Can it run the buggy? It's only 2 pounds heavier then my CRT .5 Brushless.

Is it possible? Or do I need another motor system?

You could make it work, but it would not have 1/8th scale performance. If you start with conservative gearing and work your way up until something gets hot, you will probably be ok. I suspect it will be the ESC that is the first weak link. Your batteries will also have to be pretty good to support this type of use. Probably 35C or higher.

we ran 1/8 ep indoors on 2s and found that it is rough on the ESC and batteries.
You will have to have the right combo of ESC,Batt,Motor.

I would only run 2s if this was a rule and I had no other option.

I disagree 100%. Caster was running a concept car called the 748 and it worked great. On big tracks it had trouble on long straights and couldn't clear big jumps, but was deadly infield. Motor and esc were cold.

I did not say it could not work just that the combo of ESC,Batt,Motor would have to be specific.

Can you offer specs for running a 2s setup with an 1/8??

This would be great.

A big issue is what 1/8th buggy are you looking to use? If it's one of the heavy ones, then that esc will have trouble or your batteries will be in trouble if they're not a high enough C rating. The motor will be fine just have to fine tune your gearing that much better.

2 pounds is ALOT.

It's on the title.

It's about 6.5 pounds 6 poundish. Didn't think 2 pounds would be allot for it. Maybe another ESC would have to come.

What would the runtime be? Can anyone give me some insight on gearing with my 3500L Tacon motor?

Will that motor even bolt up? I don't think the spacing is right for an 1/8 motor mount.

The motor i have is almost as big as a 1/8 motor. Its huge for a 540. Its long. I think it'll fit. That is a very good thing to thing about it completely slipped my mind.

You could be right, but the issue isn't the length it's the diameter. 1/8th motors are generally 40mm or 44mm in diameter. It's all about the screw holes. But it's easy to test

XERun 80a esc didn't like 2s in my 1/8th scale buggy.

An EZRun 60a should handle 2s in your 1/8th scale no big deal. I ran this on my 1/8th scale buggy to SC conversion without issues. I tried 4s with it with an external bec but blew 2 becs out. An offbrand then a Castle, Castle Tech didn't see an issue with my installation. Still scratching my head over it.

If you have the funds and want a great esc combo for what you're doing, get the EZRun SC8 combo. Its made to run 2s to 4s. I currently run that esc with a Castle/Neu 1/8th scale 1800kv motor and its been great in my Lx1e.

We were running the hobbywing black 80amp esc with no issues. We were running 2000 kv motor with 16 or 17 tooth pinion on Caster 44 diff gear. Did you program it for lower voltage?

We also did it with a Castle system.

I did everything possible, checked and rechecked lipo cut, checked for reverse wiring, added caps, tried different 2s lipos. Nothing really solved the issue. I sold the esc to a friend who runs it in his Emaxx on 4s and he's extremely pleased with it.

Really? A ezrun 60 amp esc powering a 1/8 buggy. Think it can pull the lx2e with motor in my op? Ill need a 40c 2s 5000mah huh? What about runtimes? Im a bit suprised looking for feedback guys.
