Another thing I was worry about E4RS is motor getting hot problem (due to motor sitting behind battery without any air flowing toward)....but after the SAT race, I think I don't have to worry about it much....I was running E4RS internal 2.0588, with 90T spur and 44/45T pinion...that is 4.20 and 4.11 final...using SP GT1.1 with MAX timing and Max DRRS along with Novak 17.5 SS Pro....temperature after all races were 135-145 range. I think...to max out the motor, temperature should be around 170-180 degrees, right...?

Any idea..? I think I can push the motor a little more...last SAT was hot, 85 degrees temp, track temp was 98 degree...RP30 after run were all 100-110 degrees range @ 4 corners.
