That was with a tc6 that you qualified 3rd ? Your son also ran a tc6 ? Good running guys, next time it will be a first and second place finish...lol....I also sometimes weigh my cars with no motor, and add about 180grams to the total, just so I can see where the car will end up. Most racers say an additional 50grams won't hurt. I have to choose lightweight batteries to even get close with my tc4's: stock(1465g) ,13.5t(1448g), 3.5t(1492g to 1538g), 7turn brushed(1534g) ....I could get them to weigh less with low profile savox servo(-20g), tekinRs(-20g), and lightweight screw sets for the stock and 7t brushed(-20g), but that would cost too much money !!!
