    Hello there,

    i have some questions how is the best way to reduce the load from motors or the gear box on a 6DOF motion sim.

    the motors are not overpowered -> 120 or 130Watts (24v) so i think its the best to reduce as much as possible of the payload ( Seat, Driver (75kg) + VR (no monitors), Steeringwheel and the Frame) round about 120kg (?)

    Theoretically, can i negate these 120kg complete by using three gas springs with up-force of 40kg each ? so i can use them between each side (see paint pic) so i have theoretically Zero load on the motors/gearboxes by standing still ? and for up and down movements the system needs only a small force ?

    another idea (maybe complete nonsense :-D) is to use counterweights on the leverarms itself. theoretically every arm has to push 20kg (120kg payload / 6) so if i extend the lever in the opposite direktion and put a 20kg weight on it ? if i extend the arm much longer i can put a smaller weight on it because of the greater leverage ?! (second pic - red and green arms) does this help to negate the payload as well ?

    Gas strutts do work, but dampen down the motion.

    Try and use motors thst have plenty of power for a good experience.

    Maybe some diet? Use VR headset only (not joystick or wheel or pedals)?

    Haha maybe I could go to 50kg before I die steering wheel includes pedals I think the additional 1kg can be irrelevant
