does higher gearing increase rpm or just the voltage?

I do run 5s like tc3 said, it been working for a while now-i got them for free so why not beat the snot out of them...

just my opinion.

except for the fact that the fan can cool both the motor and the esc from one spot lots of airflow :D

5s wow hahah. thats like 21 volts on a 12v fan hahah. do you know what brand your fan is? and what does cfm mean?
