    Hi
    I'm planning a 6DOF build. I'm deciding between motors with levers and linear actuators.

    Are there any special considerations when using a motor with levers? Someone told me I have to consider the "sinusoidal" movement of the motor levers vs the linear movement of the linear actuators.

    If I did a build using linear actuators, and then swapped them out for motors with levers, it seems that I would get different motion ?

    Make sense? Or is it nothing to worry about?

    Thanks.

    Simtools will compensate for the difference in motion

    It works out the difference between linear and rotary motion automatically

    Linear actuators look very cool, but are expensive and noisy imo

    They have very good range of distance, very suited to a flight sim

    Gearbox and levers have quite a lot of power for the cost and can accelerate quickly making them suitable for driving sims

    somebody did make a linear actuator that used a belt and motor, could also be done with a simple chain amd sprocket !
