All I can say is ditch the NC1 motors, they have been hard to obtain since 2009 and even became harder in 2014. Come into the daylight and the 21st century.

Al Penrose, or BWA as Munter pointed out sells a 14k replacement for the Ninco called a BWNC-1 that is much better than the original NC-1 Ninco made.

They are still available today at around $6 Canadian funds. It's considered a current motor still on the market for reliable, slow class cars.

I have about 20-cars with these motors. Running at 12-volts, they simply will not die. I also keep an inventory for future builds. (The larger motors on the left)
