I have a mugen mrx3 with a megatech .21 onroad with a rb concept carb on it. This car runs very well. The engine only has 1/2 gallon through it. Last time I ran it was over a year ago I started 6th in the B-Main won that and then took 2nd in the main. You can go to rams website and check out race results on 11/12/06 and look at sportsman B-main and then sportsman A-main. Due to a new job have to put the hobby aside awhile. Anyway the car comes with chassis and engine and pipe. No radio or personal transponder. If you are interested email me at seajj2@yahoo.com. Sorry about the picture I have to get a new camera $250 plus shipping
