RE: What hpi
First you say all around and the MT 18SS is not race legal as most places and none of the sanctions have a class for 4 wheel drive stadium trucks in the US. Then the Rush Evo has been discontinued so sooner or later parts are going to be hard to get. The Rush is a fun basher but not a good racer. If you are going to get a Savage I recommend getting the X SS kit. A 21 in a 12-pound truck is not good. I have a HPI MT, original Rush, Savage 4.6SS and a RS4 Micro and all are great vehicles. I did not vote as I say all of them are good.
One other thing if you go MT get the 18SS kit as the RTR had many weak points!!!!!!!!!!!!!
