Hello all, new to the forum and also new to the brushless system

I am currently running a 13.5 MMM SP motor on a tekin RS pro for 1/10 TC. Was wondering what would be a good starting gear ratio for 13.5 boosted.

Also is it true that I should not run anymore than 64 degrees total of timing advance? and is the ballend timing on the MMM calibrated to the software timing? ie. if I am running 11 degrees on the motor - then I shouldn't run more than 53 degrees on software

thanks for the help
