Gearing is 14/42 but in this video, through EPA and curves, the ESC was limited around 75% (that should give around 1500rpv, I really miss that motor
).
With the fan the Mamba Monster won´t reach 140ºF, it doesn´t matter how much you can abuse it, going to try 16/42 when the 1500 arrives and would try to take away the fan too. The only limit is the motor getting up to 175 with too much ease...
Glad you like it!
