5s in slash?

[rootar]

the motor would be turning the same rpm as my 9l on 3s 5000, but the higher voltage would be more efficent, mine is also geard for 45+ and i dont have any heat problems i was just thinking about it since i have 3 5s 4000 packs that i use in my buggy and my 3s5000 maxamps has just about lived out its life (its over a year old so im not expecting to last much longer) it wouldnt be any more powerful than my 9l and 3s it jsut wont be working as hard as my 9l and 3s (which dont work very hard as it is). i was just thinking aloud.
