    Greetings from fu&€ing cold Finland.

    I've planned to build a small simulator to my self. And because we had good offer for G29 (169€+shifter 59€) the wheels started rolling.

    My friend drives rally and he sold me his "old" bucket seat for 80€. And because I've had many kind of cars since 13yo, there was some harnesses in garage to use in this build.

    I've already made the bottom and that upper moving frame ready. Handbrake and some mods (stiffer brake pedal and harder H-pattern with 3drap products) is also already made.

    But dear friends, I need some serious help with those motors and placements. I got couple 24V motors with gears for free and On was going to use those if possible. Planned to run those 12V.

    So where and witch way should I mount the motors? Back or front? I put couple samples how i thought those might work. There are some pictures to show this case.

    I'm going to use arduino and mm in this first prototype and if it works well there could be some improvements on future like sabertooth, better motors and so on..

    Thanks for your help already and sorry if my spelling isn't so good.

    You have not given the specs for the motors and gear ratio, so I would suggest a foot mount design as it gives you the most inherent design leverage for motors that may not have a lot of torque.

    Motors are shown in that picture. Those are quite slow ratio ones but if I get this even slightly work with those it would gime me a boost to invest on real motors soon :)

    Wuhuu!!! First time that this moves by it self x) Motors are driven from adjustable power supply with 24 volts. At this point I realised that those motors are too slow for this use =( Well.. I hope that if I buy now good ones those will last for a long time.
