This is from Vega's blog:
This is my modified Tamiya Evo 5. I put all the batteries, and also I mounted the motor. This is what it will look like. I'm going to install:
Motor: Neumotor 1515/3D
Batteries: Thunderpower 3S+3S+6S = 12S
ESC: CC HV110
Final gear ratio: 1.42
The only thing modified is the motor mount.
I have to say, this car has the most power for its size that I have ever seen. Take a look at the spur gear. Its huge. Compare Vega's car to Magnus's car. If Magnus can get 135mph with a Mamba 7700 and 5s, I wonder what kind of damage Vega can do with a Neu 1515 and 12s. This will be exciting to see.
