low end motors vs high end motors

ok i think i get it now.

here is my next question that never really got answered. can a neu or lehner run on a mamba max?

and would those motors be ok on 4 cells. 4800mah?

my run times right now with my 9xl are about 2 1/2 of my friends tanks on his nitro revo. and they lost for about 15min. but thats not driving it hard for the full time. its just taking it easy and going off jumps. i should be going to the track in a few days so i well really see how long my run times are goign to be when i drive it hard.
