Traxxas TRX-4 Brushless Upgrades 

We install a Revolver 540 and Mamba X, and are pleasantly surprised at the sensorless control! The Revolver is our first motor design, a sensorless outrunner. With the advances of controllers, sensorless is again a very viable option!
The tested Revolver motor is 1800 kv and can be found here: holmeshobbies....
The tested ESC is Mamba X and can be found here :holmeshobbies....
