well its not really tricky but almost, Right now I'm planing on building a sand rail which is going to take up some money and I'm only 15 but I'm really going to be 16 soon so i dont have my working papers which leads to know job lol, but I'm interested in rock crawlers very much and I havent done much looking around but is there any like 1/18 scale extremely Cheap Crawler out there so I can fool around with? And if there is, is there alot of Modifacations that can be done to it so when I do get a job I could make it better? :\
