If you check the Tekin website--you can get a LOT of settings for different setups for your 1/12 car. I had nothing but trouble trying my car w/ 13.5 motor on 1S until I used some of the suggestions off the website. Now the car's ballistic---motor stays cool--and I can run 9 minutes no problem---so a little warm up time and an 8 minute race are a no-brainer!!
FWIW
