yea "rc freak" hmm the D-Box do maintain your drifting but my friend has a 1/18 Micro Rs4 RTR , the one that hes trying to figure out what to buy. Trust me its not hard drifting with an 1/18 size rc , took me 2 or a little bit more to drift without the D-Box. 1/10 Size took sometime because thats what i have and i use ABS tires. Its worth it though, 1/10 size is a good size for drifting. My opinion
