So far I really like my little Goliath. This truck is made for bashing and crawling, not speed. I think it tops out at 10-12 mph max with the stock 550 motor. But, it is fun as heck to dive. It crawls curbs and small stairs/step very easily. The fun challenge of driving it is figuring out the correct approach to climb over an object and using the right combo of throttle and steering. The kit instructions are not very good, I was used to nice diagrams from HPI, PTI supplies only black and white photographs that look like bad photocopies. Couple weak points are the body mounts which snap very easily (broke one already) and the stock servo mount which is flexible and feels like it could break upon impact. I haven't driven it enough to give an better review but these are my initial thoughts.
