even though the tlt is 1/18. When you buy a real chassis, most are the size of a regular or bigger than a 1/10 scale. I am in the process of building one myself, it is way easier to just buy the kit, because there are so many useful parts in their.
I estimate my build will cost about 400 dollars. This is the TLT axles, Tires electronics, SW2 chassis, and other things. It sounds like a lot, but for a real crawler, not bad at all.
