I Like the Velineon over the cc 4600. After a long bash the it stays under 170F (also running in a 100F+ weather)I have it geared 16/66. For a $70 motor it's much more powerful motor than a 8l or a CC 4600. If you run 12 Cell nimh on the Velineon motor you will be very pleased with the speed, and get 25 min or more runtimes.
