Dumb SCX10 II servo voltage/torque/speed questions

[ANZAC]

Servo questions: My ESC/BEC can output either 6.0 or 7.4 volts. My receiver can handle up to 9.6 volts. Running 3s 4000mAH battery.

I need two servos (one for steering, one for gearbox).

I assume both should be the same voltage spec.

Any huge advantage to using 7.4v spec servos over 6.0v? Just speed? (there are fast 6.0 volt servos...) I am just bashing/crawling around, not racing.

Also, for an SCX10 II with stock 1.9 wheels, do I need a high torque servo?
What type of torque/speed should I be looking for? >=200 oz, < .011 sec ish?

Thanks.

Given the same torque and speed a higher voltage servo will draw fewer amps and run cooler.

Higher voltage on servos will give you more power. Check out the ratings of most servos, normally they give a 6VDC and a 7VDC rating of oz/torque.

Generally speaking, 200 oz is ok for trailing. 300oz is good trailing and light to moderate crawling. 400oz+ is good for crawling.

Thanks, that's super helpful. I'm coming from a 20 year old Tamiya TB-01!

I assume for crawling that torque is more important than speed, within reason.

Correct about the torque and speed really doesn't matter at all.
