I was thinking about giving Castle a call to see if I could get one in black. I plan on running over 50K and I hear that Neu's don't like those kinda rpms. I figure if they made the 2200 to run off 6s, that is what I am going to do. But I do have the Tekno Motor mount and i will be putting a fan on the motor so the green might not show that much.
neus will handle 50k, it's all about gearing and checking temps. You could always paint it black, speedassault did an awesome paintjob on his neu in the project x forum
