Get the 9 dude and dont look back.. The design is the new era and more buggy's will follow like it!!( tamiya has produced a buggy with a tilted engine the trf801x) 999999 all the way!!!!!! the jammin is just an x1 with tons of hop-ups nothing special(my opionion).. Also that non bolt on wing takes a full second off lap times! Kortz hasnt been as succesfull untill now and i wonder why
