Theta Servos Razor-C1 Brushless High Voltage Servo (Black Edition)
Even though this servo is mainly marketed for large scale helicopters I used it for steering my ET48 2.0: and I have to say I'm really enjoying the superior torque, precision and speed. I'v only used a couple of battery packs so I can't say much for reliably but I'm guessing it's designed for the normal abuse of a flybarless systems it should hold up well for Vehicles.

Only wish the app to access setup options for the servo was endorsed by Google Play as the app will need to be side loaded into your Android phone and for some it's not a very secure option. At the moment I've not accessed the setup options but it runs great out of the box anyhow. However accessing setup would allow options for increasing both speed and torque which would be even better especially for the value of this great servo.

To access setup options you will need an android phone with NFC enabled hardware.
