My M06, all stock, weighed in at 1141 grams with ESC Castle SV2, Silver Can, Specktrum Receiver and a Reedy Wolf 3000ma Lipo. Sweep 33's and no body. Adding the body took me to 1301. Car handled awesome and was very fast down the straights compared to some of the M03/05's. I wouldn't worry about the weight some much if you are competitive. With that said I would remove it and place it where it was needed or if needed as all. Whenever I have purchased a preowned RC, I always take it back to a stock kit build and tune from there. My M06 was a new Pro Kit build so it is all stock. Using stock oil, blues in front, yellows in the rear. Running -1 Camber. No traction rolls and I am pushing it hard through the corners. running it tonight for the first time in a club race, I am curious to see how it does in a pack of M03/05's. I am thinking it might get turned a lot.
