    I am mainly involved with rally sims Dirt Rbr etc so would like to incorporate rear slip into my design, i have 2 rigs basically the same design one i use which i use the back end and pedals part and one i have complete.
    The design of the rig lends itself to motion so would be a good base.to start with i would like to incorporate just the seat element then later if i like the idea will progress to 2 extra fronts.
    I like the design of this platform and have contacted frex for a quote for the parts included here.However i would like to have a idea as to if i wanted to achieve similar results with DC motors what would be the equivalent needed parts to achieve a similar result

    Any help would be much appreciated.

    Here is a basic list for a 2DOF DC option, which would likely out perform and outlast a Frex system and which you can add additional DOF to like traction loss.

    You would need some decent DC motors with 25:1 or 50:1 wormdrive gearboxes, depending on final design, something like these: http://www.ebay.com/itm/GEAR-MOTOR-...384?pt=LH_DefaultDomain_0&hash=item51bd392f00

    There are other potential sources for DC motors: https://www.xsimulator.net/community/faq/dc-motors-shopping-list.32/

    You need 2 JRK 12V12 control boards (simple to set up but a bit more expensive): http://www.pololu.com/product/1393/

    Or an Arduino and 2 Motor Monster or similar boards (cheaper but a bit more work to setup).

    2 potentiometers, I use Hall sensors as you can't break them if over rotated, they have good resolution and are very durable: http://au.element14.com/bi-technolo...fs/sensor-hall-0-2v-20v-to-10v-pin/dp/2319662

    2 flexible coupling of the right size to connect the motor shaft to the pots: http://www.ebay.com/sch/i.html?_odk...0&_nkw=flexible+coupling+10mm+6.35mm&_sacat=0

    2 HP Server PSUs: http://www.xsimulator.net/community/threads/how-to-modify-a-server-power-supply-for-12v.5774/

    An old car tailshaft to use for the universal joint.

    Some switches, fuses and wiring.

    Many thanks to Noorbeast for the very helpful reply i have now got quite a lot to work with. I now need to work out how to apply rear slide on the initial idea that i had.
    I got the quote back from frex and it came to 2000 euros for all the bits for 3dof which was shipped, however compared to 2900 for Prosimu i am not convinced it sounds such a bargain.
    So will go the dc motor route.
    Reading the posts here on how good these motors are and how well they stand up against actuators it is very surprising that there is no one commercially gone this route.

    My next question is i found these on one of the links to a standard motor i was wondering why nobody was using this type of motor.
    from motion dynamics.

    hmm 1000 bucks for 2 dc motor setup doesn't shout out bargain i am still wondering why the dc motor powered unit in the design of a actuator isn't popular and there 80 euros
    surely it would be ideal for motion setups or am i missing something.

    Look at the specs (5mm/s), most do not come close to the speed of what is needed for good motion 200mm/s+.
