Load is load. If you want to move a 8lb buggy to 80mph you have a set load. For that application I would like a motor that has plenty of torque, but one that can handle something like 60k rpms. A 1515 motor would be good for torque needs for that speed, and spin the motor about 50k and gear appropriately.

I think that would be a better option than a larger motor spinning slower. The lower gearing with the faster spinning motor will help sartup as brian mentioned, and it will also have a better "feel" when driving. Motor spool up will be faster as well. Not sure if acceleration will be better, as that depends on traction.

So a 1700kv motor on 8s with 1515 dimensions would fit the bill. You could try 2200 kv motor on 6s but you will need good batts and some airflow over the motor/esc.
