i have seen those before and they are complete junk. if you want a cheap clone, get a kingmotor baja. it is a clone of the baja 5b and is 100% parts compatible with the 5b.
How do you know theyre complete junk if you've never driven one? Most 1/5s are very reliable and are decently durable because people dont beat on them as much as 1/10s or 1/8s.
