Larger tracks and the turbo/timing boost puts the 27 turn to shame.
+1 totally agree.
I race at a track that is only 10x15metres and there is not much difference between a good 27t motor and a 13.5 with boost.
theres only so much power you can utilise on a small track.
don't spend your money on a brushless system until you know its the motor that's holding you back.
If you are consistantly to 4/10ths of a second between your fastest and average lap times in a qualifier and not keeping up with the field, then theres a very good chance you need brushless to keep up with them.
Bigger tracks are different though, a good 27t just doesnt have the same grunt as a 13.5 with timing boost down the straight.
