Right now I'm leaning toward a RX8 & 1700KV on 6 cells thinking this would provide a better setup long term for heat and efficiency?
Like Bill said no rules except rubber tires only.
Not sure on motor setup. A 1700 on 6S would be equivalent to a 2650 on 4s but I'm not sure how heat will be or how the RX8 and motor is going to like running at 6S in such extreme conditions. The Cobra has a lot of drivetrain resistance from having a center diff and 300k fluid in the front diff.
There's going to be a lot of load on the motor especially in 80+ degree temps with a 130 degree track temp. Im still going to run my DM1 just incase if I'm not able to keep the temps down in the cobra.
In my DM1 I would hit 170+ degrees in a heat/main with a 2250 truggy motor on 4s with a drive train that is a lot more free
I will probably have to play with front and rear diff fluid weights and maybe lock the center diff to free up the drivetrain on the cobra
Once the track is opened up I will start playing around with different set ups
