I was thinking of ordering this:

Tekin RX8/Redline T8 1/8th Scale Buggy Brushless ESC/Motor Combo (2050kV)

But drop it in my 1/10th Truck. Just the ESC hooked up to my current 1/10th Sensored motors replacing my Losi 9500 ESC.

I have been thinking of going 1/8th Electric in the future, and figured I could move the 1 ESC back and forth between vehicles as needed. As I would run 1/8th, or 13.5T Truck, but likely not both the same day.......
