Which Titan Motor Should I Use?
 

Hello, I have a rustler chassis and I want to know which titan motor will do better.

The Titan 21T can handle 14.4 volts but has less rpm and more torque.
The Titan 12T can only handle 9.6 volts but has more rpm and a little less torque.

I want to use an 8 cell battery in this car, but in order to do that, I could only use a Titan 21T.

Will the performance of the 21T with an 8 cell beat the performance of a 12T with a 7 cell?

Remember, this is in a rustler.
