    Here it is , after having realized my reproduction of 2DOF CKAS, I therefore decided to go on what is the best in the world of simulator , a 6DOF, drawings and measurements directly obtained from an owner of a CKAS 6DOF V4 , I even have the photo of the plate of the original motors used , original motors are SEW brand : 0,55kw / 12rpm / 300nm with brake, mine are 0, 55kw / 14rpm / 350nm but without brake, so mine are faster and have more torque the brake is not really necessary cause it's just to block the simulator on its current position in case of current failure and also to maintain the position when simulator is turned off.
    The inverters of the original 6DOF are SEW brand also : Movitrac B / 0, 55kw . My inverters are Omron j1000 / 0,55kw .
    For electronics i'm using thanos excellent AMC644USB with 6DOF extension of course , and digi-key 6127 360° potentiometers .
    I got excellent speed , i'm really proud .
    Here are some pictures and 1 video of testing with x-plane 9.70 :

    Hello, I think it's great, but I think you could have put less 400W servos sustained reductions 60-80:1, bring home encoder, are much more dynamic, and smaller size.
    asynchronous induction motors (squirrel cage) are not the most suitable for these applications, plus the drives are in open loop are not very accurate and slower than a servo, and behavior will tell us once completed, a greeting.

    Dont forget about the 4-5k price tag too, not for everybody can afford it , plus here in Australia all 240v stuff like this needs to be wired by a licensed Electrician and to me I would not DIY if it killed somebody, you will face a very large law suit. Just be careful please it all Im trying to say 240v kills regularly and there is legislation in a lot of countries that govern the construction of 240v system be a sim or anything 240v run.

    By the way have you addressed the slowness of the motion yet ?
