Torque servo S777CG/6BB

hello
I’m using a servo S777CG/6BB to control the direction of a car for a autonomous driving test.
The specifications indicate that this servo has 42kg.cm when fed 6v, however this servo can not turn the direction of the car when it is stopped. The dimensoões car are: 60x40cm and about 15kg.
The car batteries can provide 100A peak.
what I can switch to this servo work?

Hello.

The only servo we carry with higher torque than the GWS S777CG 6BB Giant Servo is the Invenscience i00600 Torxis Servo.

By the way, are you sure you aren’t currently being limited by whatever you are using to supply 6 V to your GWS giant servo?
