i dont know a whole lot about these things except they're real fun to play with. A friend of mine has one that he is about $500 in to and its pretty nice. He told me i should just build one from the ground up since a complete one ussually needs upgrades anyway. What are some major parts that i would want to make sure a crawler has if i buy one. Any opinions on chasis or axles or ? If anyone has a good one ready to go i have cash. 425-232-4466
