We have used GTR2 and later rFactor for the TWIP Time Trials. However we haven't done those in a while I'm afraid. Maybe we should again!

    Arguably the best FF wheel for the PC in the world, this wheel was built by Bodnar around a Kollmorgen servo motor intended for CNC mills.

    Not really a wheel package, it includes a Kollmorgen AKM-52G servo motor, 480W dedicated power supply and Leo's own USB FF controller.

    Some of the awe-inspiring specs:
    3000RPM Max vRotation (!)
    13Nm max torque (G25: 0.5Nm)
    480W dedicated PSU (T500RS motor rated at 65W peak)


    In theory it's even possible to install a second PSU and increase the speed by 100% and the torque by 50%.
    I don't think you want that  Grin

    Tell me where to split the topic and I will.
    It would be great to have a dedicated topic for the new leo wheel. Pretty sure people wanna hear all about that!

    I wanted you to cut the thread at post #79, sleepy head!

    Lol.. i was wondering about that!  Grin



    I think this belongs here too Remco, so people can be astounded at the amount of force generated from the wheel.. you can definately see it.

    Personally, i'm afraid this wheel will not be sold in large numbers, as the thing is so fast and powerfull that there's bound to be safety-instructions at one point... (or should i remove this line)   As you "let go" in the crash footage, Remco, that thing spun so fast, i was thinking of a blender!

    Anyways, copied from Remco's topic:




    And here are the promised videos. I threw in a bonus showing a rather nasty crash  Grin

    Makes my wrist hurt watching it.  I think I would be very cautious having friends turning laps with it.  Add a few actuators to punch you in the side and the back of the head, and you can experience sim crashing as well as racing.

    This was posted by Leo on the iRacing forums. I figured I'd repost it here for everyone who's not an iRacing member.

    "Gentlemen,

    This is a drop-in replacement for G27 electronic guts that provides 100% linear response, removes deadzone, supports all original buttons, pedals and shifter, allows to overdrive the motor power to 48V and saves the world in other little ways.

    It will be properly announced when it's ready in April.

    Leo"

    So excited!!!  excited excited excited excited excited

    Um, I hope everyone realises that this G27 drop-in unit has nothing to do with Leo's own FF wheel which this thread is supposed to be about.

    Leo's own FF wheel

    I find it funny that he's marketing as a wheel when really it's only a super powerful motor and on it's own nothing like a wheel but that's semantics!  smile

    How have you mounted the wheel to the motor? I know your setup is a little different but I'm interested to see how people are actually installing this, there is so little information and no one seems to want to share!

    He doesn't market it as such, quoted is my simplification.
    Not a whole lot of marketing is going on to promote this package but if anything he would call it a force feedback solution.

    I mounted my wheel with a cylindrical clamp not unlike this one:

     Grin When I was talking to CST last year it was definitely a "wheel", hence my shock when I found out it was only a motor (given the cost!)

    Do you have the motor at the end of the steering column in your cockpit or have you lost that now and are directly connected to the motor? I know you are all old skool and have manual shifters and no buttons but is there enough room to mount paddle shifters/QR boss, etc to the motor spindle or would you need to extend it?

    Again, not quoting Leo.

    In my P34 the motor will indeed be placed beyond the footwell. For now it's in my old frame so currently the wheel is attached to the motor directly. There isn't any less distance between the wheel and the housing than on a G25 I'd say, and because the motor housing is only 130mm in diameter you should be able to install flappy paddles and/or a QR without a problem. The only problem you might encounter is sourcing a 24mm version in the first place, as I understand it that's not a common size.

    Can I assume you didn't buy it through CST and directly from Leo? CST led me to believe that they would be dealing with all the sales but the units would ship from the UK. If the price became more competitive I do think it's a viable high end wheel, especially as it is in Europe so no issues with time zones, over zealous customs officials and endless shipping times!

    No I didn't go through CST, I managed to get a deal from Leo via a mutual friend who also has one directly from Leo.
    CST are idiots who sell mostly crap and I don't know why he would ever partner with them.

    I still had to wait 8 months though.

    I did wonder the usefulness of partnering with an Oz company when you are in Europe!! I am also sure CST were marking it up considerably - 3000 for a motor and controller board seems ludicrous when the new all singing all dancing Frex wheel and the ECCI7000 comes in around 2300!
