I think Id say the Rc10Gt. Awesome trucks and have TONS of parts available for it. Its a 2 wheeler though. Mostly for racing but I've seen some as bashers. (I bashed 2 of them)
good and cheep dont normaly play well together. the rc10gt is a nice cheep rig, and with some good rpm parts in key places it can be a tough little truck. i beat on mine just as hard as any other rc i have and it keeps on going. but my truck is about 90% rpm parts.
you could get a xxx-nt but losi is a bit more proud of there rigs. the 2 leaders in st are xxx-nt and the rc10gt.
hers a pic of a tough rc10gt ( i know its tough cause its mine )
I've since replaced the engine and put the steering parts on that are missing in the pic.
