Esc HELP!!!!

[ex-sco77morgan]

Why do top racers use a sphere comp in a 2wd and a TC Spec in 4wd buggy

Is it only because of size ?

I answered the question for you, on COBRA's site, dude.

the TC spec is rated slightly higher and has the fan for extra cooling. 4wd put more strain on the ESC/motor than 2wd, so the 2wd doesn't need the extra fan etc
