I have discovered a cure for my thermals, For the longest time, i would keep shutting down at the 3.5 minute mark with my 4.5, I eventually switched back to the 5.5 so i would make a full race. I then in practice set my min. drive to the setting 1, from both the 2 and 3 settings. I ran 6.5 minutes in 90 degree wether. ran the same setup the hext day in both my heat / main, and did not have any shut downs. By the way, the car was still a rocket
fdr 10.17, did not try a higher gera, but didn't need to as the car was plenty fast.
Temp coming off track was 157 degrees

My settings were
7 on drag brake
1 on min drive
3 on the min brake setting
everything else is default.
