Motor suitability for Durga

[outspaced]

Hi everyone,
I'm very new to all this and have just a quick question about upgrading the motor in my new Durga. I installed an Mtroniks Viper Eco20 ESC in the car and my question is whether this

would be suitable for my setup? Not planning on racing or anything like that in the near future, at least, just sure that soon I'll be wanting to upgrade the vanilla 540. If that one is not suitable could anyone recommend one that might be? I have a slipper clutch on order . . . . !

Thanks in advance.
