i suggest buy kawada m300GT R....can use mini ghost tire....large lipo battery....good look mini body and 1/12 pan car body....jethobby should have and i remember around $1600
but disadvance is less parts support...
this m300GT"R" use carbon fibre....same as those 1/12... http://www.youtube.com/watch?v=vIj_HUt8Pqc http://www.kawadamodel.co.jp/kit/m300/gtr.html
use lipo battery...suggest use brushed fan black pig...or brushless ...3000 kv motor
it can't use too fast motor but if play at wan chai...it enough...i have a friend play m300GT and it more fast then my f1...
if want play real 1/12...i also suggest asso r5 or 5.1...due to parts support problem....even asso have parts more then other brand in KWS...but compare with those 4wd or f1 parts...still less..
