Well tested Melvin's "The one" tonight and thought it was pretty fast. It will def. keep up now. After I figured out my gearing I started to play with the motor timing. I realized that I had it way down so I took it all the way up and started backing down through the night. I wish there were actual deg. markings on this can (novak 17.5) so I could tell the degress. I had it just a little off of the full timing mark and it picked up alot of speed.I then started playing with the torque curve and if feels almost perfect. It has tons of rip off the corners and The motor never got to hot at a 4.21 on a 75x45 carpet track. I think this will be the profile I will stick with.
