Well, I can tell you that I have the baseline model is a great model, hey, I tested it with a hand held GPS, and it hit 18mph. As for the Brushless model that is even better.

Pros
1. It is a lot faster.

2. Less maintenance for the motor, because it does not have brushes.

Cons
1. It is over 100$ more.

Now it's up to you on what you want to buy.
