Yea, I test ran it today and it does quite well. I will get some video for ya on Friday, should have a few of em hittin the track then. The pinion is a 15t at the moment, it works well for the local track. Its good for high 30s and 20 minutes of racing, running under 140 degrees. I could gear it to hit in the 60s easily, but its pretty lame running up and down the street with a race truck......
