which is more powerful/fast

[SpEEdyBL]

The 380 motors have a smaller rotor than the 540 motors so they can spool up faster. You can also get more runtime out of them. I'd say the 380c 8t is slightly faster than the 8s. Honestly, I haven't seen any impressive numbers with the 8s. 30-35 mph is typical on 6 cells in a rustler or stampede and 40 mph on 8 cells. You would expect that the bigger 540 motors would be more powerful, but that's not always the case. I assume the 380c 6l would be the fastest of the bunch.

alright thanks, ive been readin that some qaurks are havin some problems so would a warrior 9020 be over kill for a 380c 7t?

for the 7t you can use a 7020, im going to be using that and the 7020 should handle it fine.

actually which draws more amps, the 380c 7t or the 380c 6l. i would run the 7020 but i got the idea that it woudent be enough to handle the 6l cause in the future ill run 7 cells and i dont want it always thermaling but if this is not the case then i would definately pick up the 7020.
the help is very much appreciated
