The set-up changes were more done to suit my XXXKE to run better on that specific track and under those track conditions (nothing too major). These tips came from the Best two drivers at the club and their input definitely helped. I changed my front springs, made some steering adjustments, etc. You can go ahead with installing the Novak Brushless with no problems at all. I just recommend that you make sure the ESC is placed as far away from the edge of the chassis as possible to avoid the body from rubbing against the ESC's heatsink oce it's mounted. It may still touch a bit so a thick tape on the uderside of the body should help spare your paint job from scratches.
Lastly, be sure to always check the heat on ESC's heatsink. According to Charlie, Novak's head technician, It should be around the 160 F level after a good hard run. That's about 3-5 seconds of thumb time.
Best of Luck and enjoy your 18-20 minutes of runtime!
