I would get the Yokomo because it's shaft drive and I really like shaft drive. But if your planning to race your car out doors too than I would get the X-Ray t1 raycer. If you drove the Yokomo out doors it would scratch up that beutiful alum. finish on the chassis
. I would get the t1 raycer over the evo2 if I were going to race carpet or out doors. I know a x-ray team driver and he likes the raycer more then the evo2 even for racing on indoor carpet. He said its much easier to drive and prefers it over the evo2. Just my 2cents.
