torque of a stepper motor

[Nigel Goodwin]

thanks for your info, Nigel :wink:
is the torque high enough if i use only 5V to drive the servo? i there many model?

They commonly work off 4.8V in radio controlled models (four AA NiCd's) so 5V is fine - torque should be plenty, it's what they are designed for!.

Bear in mind, a 2 foot long ,glow plug engined, model car, doing 80 MPH, is going to be steered by one!, with another one working the throttle.

i didn't know that powerful a servo is!! if i knew it, i won't try the stepper.. :cry:
but what is radio controlled?

Have a look here https://tamiya.com/english/rc/rc.htm, Tamiya are the leading manufacturer of radio controlled cars.
