In my day we had brushed motors with all sorts of characteristics and we used to swap them to suit the track layout and grip levels. So say it was a grassy track with high grip you would put something punchy like a triple or quad in but if say it was slippy but the track had a long straight you would put in a single which had less torque but more RPM for the straight.

So cut to modern day. 2WD buggy and I have a 10.5, 8.5 and 6.5T choice.

It seems to me these motors all have the same power curve characteristics and they are simply faster than one another? Or does a 6.5T have less torque than a 8.5T but more RPM? (not tried my 6.5 yet!)

Also turning up the timing. Does that increase RPM and reduce torque? To me it just increases both!! e.g. turn up the timing on an 10.5 and basically it is as fast as a non-timed 8.5t.

Am I missing some subtleties here??
