wrong motor. wrong battery voltage and mah.
go to
www.megamotorusa.com to view a spec/application page to get a better idea of what you need.
Also, you may very well need to up your esc to 80amps. 60 maybe borderline with the correct set up... hard to be sure with that fan.
4-5s lipo NOTHING CHEAP for this as the C rating will need to be atleast 25c.
3300-3700 mah would provide a more solid output.
