I don't "drag" my Mini-Zs. I run them on an RCP track consisting of 4L's. It is also the same track where the Kyosho Mini-Z Cup was held last November. The winner was running a 7 tooth if that gives you any idea of the technical aspect of the track. Sure I could put a larger pinion and faster motor in any of my Mini-Zs, but I couldn't hang out with the other people on the track because the car itself wouldn't be able to stick to the track and I'd end up slamming into the rails. Consequently, it is more about driving skills than speed on the track. My Overland is a stock toy I use to play with my two cats. And, my Mini-T will wheelie on demand and it doesn't even have a brushless motor in it. The Mini-T only has a Peak Racing Chubby RS4 Mod Motor which is a lot cheaper than some Mini-Z mod motors and it doesn't have all the fancy turbos and FETS. However, I am putting a small brushless motor in my Xray M18 and it should be fast as well as keep all the tires on the ground. Finally, no I haven't measured the speed of any of my toys because there is no need too as far as I'm concerned. A good mathematician can probably calculate most of the results and driving skills determine the rest. Besides, if someone has the money or available funds, its rather easy to make a fast car but its more difficult to make one that can be controlled. In other words, the bottom line is how much do you want to spend to make a car go fast.
