    I'm looking into building myself a simple motion sim. Most important function i think is the yaw axis to feel when car starts to loose grip.
    I have been looking around on ebay for several hours and I can find many cheap linear actuators for furniture that can push/pull around 20-75kg at around 10-200mm/s most of them say duty cycle 10% so i figure this means that a 10% 10mm/s actuator actually will run at 50mm/s if you push the PWM to 50% duty cycle?

    The question is did annyone try this kind of actuators with some kind of potentiometer setup and motor controller?
    For example this
    Heavy Duty 225lb 2"/4"/6"/8"/10"/12" Stroke Electric Linear Actuator Motor DC12V
    Linear Actuator Tubular Motor Stroke 50mm 2inch 12VDC High speed 230mm/s

    10% duty cycle means 6 minits working 54 minits rest in a hour

    Ok I see. How much speed and force is actually needed to get a good simulator?

    Without an actual link to look at, I'm guessing the '230mm/Sec' is a typo, - actuators for furniture do not, or need to, run at the speeds that we require. If there was a commercially available - cheap, powerful and fast actuator out there, we would all be using it ;).

    I were not allowed to post links. Bit this 230mm/s is sold from many places. IF i remember correct börjar it's 50n Force att 230mms and 200n at somwhere around 100mms.
