Tekno RC/Impakt RC ran one of those 1300 KV 60mm motors in a Truggy and it ran pretty well on 6s.
E-Revo: If you want to run a 6s setup I think the 60mm should be fine for your track. I'm running a 70mm 2000KV in my Hyper 7 currently on 4s lipo with the soft start on my MGM all the way up and my onroad tires can't keep up with the soft start

It's only got an 18T pinion on it right now, probably move up to a 22T with as cool as everything runs (MGM is a little warmer than the air temp, the motor gets up to 90-100 after a full run, despite being Maxamps lipos they only get mildly warm).
