Well, on my mbx-5T I run 5s w/the cc/mmm 2200 combo and I am running a 17T pinon to keep the nose on the ground. I f you went down even lower than 14....Your set up sounds really good to me as is espically if everything is running nice and cool. (
DON'T MESS W/WHAT IS WORKING WELL ) Readjust your punch control on the esc until desired results for more torque would be my answer....cheaper solution too!
