Throttle/Brake Servo

[WyldOne]

I'm having a hard time deciding what servo I want to use on the throttle/brake.

I bought a Hitec 7955 for the steering. I would like the throttle/brake servo to be a Hitec as well.

What torque and speed should I be looking at. Have Google and haven't come up with an answer.

Thank-you!

For throttle you really just need to get a servo with around 125oz-175oz in of torque.
Try to find one in that range with a really good speed for good throttle response.

The hitec 5645 mg is a good servo for throttle duty.

What do we all think about the Hitec HS-7975HB (Speed (4.8V/6.0V): 0.13 / 0.10
Torque oz./in. (4.8V/6.0V): 119 / 144) or HS-7965mg (Speed (4.8V/6.0V): 0.13 / 0.10
Torque oz./in. (4.8V/6.0V): 111 / 139)

Both of those servos you listed will work great in your application.

Thank you! I wasn't too sure as I haven't heard of them being used as throttle servos. They seem to have the specs I'm after.

Yeah those are both good. Get the one with the tad bit more torque though. More power = better brakes
