well my friend, I have yet to traction roll. and My car is nice and quick. I think I proved with my T3 being a little over weight isn't going to kill you. (ran a two day about 60 grams over weight and still did well my first two day with the car) I tend to spend my time doing other silly things like racing my T3 till nitro season starts lol. I think Tackling the heat sink head on my engine is a higher priority than getting my throttle servo 2mm lower lol. Agree'd? And I am far to impatient to order a throttle arm and have it black anodized lol. I am going to lower it, but I don't have all my RX packs Lipo or li Fe yet, so till then I will stick with stock height tank. I hope to have less than 10 grams of ballast on the left side by the end of the day Titanium screws be damned.
