Hey tash, 4s2p a123 is a bit low on voltage for this motor in a truggy. I would go up to 5s for the mm, or 6s if you can (with the mgm). You could go up to 7s a123 if you wanted to, this motor can handle the higher rpm. I run my c50 15l in a new emaxx on 5s lipo thru a 125b quark. I have an 8l c50 in a buggy that I run 4s on! It spins up near 50k rpm, but does not get hot, and it has some serious power too! These are some realy good motors, wish i could get my hands on an xl c50, but I have a self imposed limit of 125 per motor. Kind of rules out the expensive stuff.

Just for a laugh, I got the c50 8l and a feiago 14xl for 125. The guy had no idea what wind the c50 was as it did not have a sticker. So I got a deal!
