dudes the EK-4 is nuts (Version2) i had that truck like 6 months ago but i totalled it[] anyways the TT .70 engine is just crazy it propels the EK-4 to nearly 65mph with the two speed thats no BS anyone that owns one or driven one will tell you. how else do you think i trashed it and the converted heli clutch is the key to putting all that torque to ground, as of now iam trying to stuff the .70 into my savage with the heli clutch[>:]
