Rustler..mamba max pro gearing?
 

I am looking to replace my velineon and vxl-3s on my rustler with the mamba max pro w 5700kv motor. Any opinions on this setup would be helpful. Im not sure what gearing to use, im going to run a 2s 5000 lipo. How fast is it going to be on the 2s pack, compared to the vxl i have now? Sorry for the newb post, im kinda new to the hobby.

thanks
