I have a MT now for about 4 years stated off as a MT 1 and now is a MT 1 ¾. Been through many changes and have MANY gallons of run time on it. Yes only get the SS as the RTR has to many weak points. A couple of suggestions get some alloy steering knuckles a better tuned pipe and sell the SS engine before you ever start it on ebay and buy a OS 18 CV-RX. You will get enough for the SS to buy the OS. The OS is a MUCH better engine. Have you been to the stadium truck forum as the longest thread on the whole site is the MT2 thread with over 460 pages and growing about 5 pages a day.
