I know a lot of people like 5s with a lower kv motor, but how well does does 3s work and anyone run 3s in their buggy?

Right now I'm running 4s in both of my rc8.2e's but I was curious about picking up a ~2700kv motor and trying 3s for the heck of it. Plus I've got a bunch of 5000mah and 6500mah lipos that don't get used much.

I have driven a Mbx4 that we set up with a Losi 550 2800kv 4 pole motor , a simple max pro , and 3s packs and the buggy was plenty fast. It did stay on the warm side , and good drivers with 4s buggies would walk away from it coming out of turns and down the straight . On the infield sections it would make up time on them. I drove that car very early on and would probably be quicker with it now , but I dont think it would have won any races at our track. Larger track , 160ft straight , hot VA summers , and runtime suffered a bit.

Good point, more heat and less runtime would be quite a downside.

I can't see 3S working very well in a 1/8 buggy. Lower voltage means higher current and it's current that creates heat...

If you want to try a different voltage, go the other direction, to 5S or 6S with a lower kv motor for less heat.
