Sorry it is a Losi XXX-4 not a 2wd buggy, would go with the 7.5 if it was 2wd. I notice that in xrc most 4wd buggies they test usually run 5.5 or 6.5, i know 5.5 is overkill for what i want which is why i am deciding on either 6.5 or 7.5. Roughly what speed would i be looking at with both the 6.5 and 7.5? Also I have heard of some guys turning down the epa on the radio if the motor is to much for the track, is this correct.
