well I have made it too my 3rd test run and after ole Country helped me out with some settings I am pretty happy with my temps 140 on motor and 110 on esc in 50 degree outside with the top off. kinda sad still not getting the wheely action like I get off my dual 9L
The XL cans basicly give you longer rumtime, cooler temps and a bit more torque, for 14 cells only id get a 7xl, no need for a 8xl, you can use it but it will have less power. For my g2r im getting a 10L on 14-16 cells. what runtimes are you getting?
