try a schulze eagle3....
i have a used the eagle3 esc from schulze and its brilliant!
this esc is extremely programable and allows you to customize your esc for your specific driving style...
you can even programme it to extend your motor life by limiting current to the motor.
think abt it... your motor only draws a specific current. excessive current is wasted as heat. this esc can limit it such that your motor recieves just amt of current enough for operation.
you can chk out schulze's website for more info
During heats, i use durex for both front and rear, with Hard inserts.
Sorex, i meant Sorex.
