get a pro 4... they have come down in price at local h/s and they are 10 times better than a tamiya... super light, tunability, and parts that dont break easily

it drives like a dream bro trust me you will not be disapointed, not to mention it already comes with any hop up you could want for racing

if you like tc4's get a factory team model... they arent as bulletproof as a pro 4 but thats how associated has always been thats why i dont like em

anyway choice is yours
