all the cars out right now have the mass of the weight centered in the pod for brushed motors.the mass of the weight in a brushless motor is not the same as a brushed so there will be no cars out with the motor weight centered and balanced for a brushless motor.i will look into if it can be done without any modification to the axle hubs.if need be i will make a rear pod to balance the pod and see if there is much difference.the biggest thing i see that is a problem with the brushless motors is the amount of tourqe they produce.they are a handfull to manage the power with the real fast low wind brushless motors as compared to the brushed
