I bet the LX-2 has e-clips I had one and sold it, due to the fact I did not like a few parts etc. The CR was the racing buggy for Hong Nor. Same with the CRT, I have the CRT x2 I like it its strong but I dont like how the open diff the bottom of the diff caseng sits on the chassis to seal it. But it makes a good basher and a decent race truggy with the right setup.
