    It’s alive! Lots of tuning to do. But it’s moving under its own power. A863938F-C563-4993-A8F2-9CE64051E890.jpeg C4179F0A-3E67-40C5-82D5-EB529557DEC6.jpeg 3AD38AA7-2920-437B-B9E6-48224199B89C.jpeg B6BCF148-2D02-4B4E-AA77-6DF2B3125474.jpeg

    Hi Bo, congrats, very good work in very short time.

    Before you are going to test the rig check out if all is working fine so far. That said, if one motor is not working properly you rig could be damaged. Probably the lever could be too long, the motors are not so powerful holding the weight of you and your seat, not to mention if you are racing over bumps and curbs...:) Good luck anyway.

    EDIT: you are on a flight sim, so slower moves are to be expected.

    First video of it moving while playing with tuning.

    Great to see your rig in action :thumbs

    How thick are the rods, as they will be subject to considerable loads?

    Thank you.

    The rods are 1/2” or about 13mm in diameter.
    They will carry my heavy arse (200lbs or 90kg) quite well so far. But I am awaiting three gas springs to take some of the load and help the motors a bit.

    It will be interesting to see how the rods hold up over time.

    Personally I would slip over some steel tubing with large washer and lock nuts either end to provide addition strength.

    @noorbeast I will certainly plan on that if they look like they are starting to bend. Thank you for the idea!

    I am very surprised by the power of these motors. I have the arms set at 101.6mm
    (4 inches) CTC and the power is fantastic! The motors do get hot after a little while with me on it. Therefore I am installing the gas springs before I damage something.

    To be honest at the latest when he adds the pedals.

    @Bo Howell Gas springs may help, on the other hand they have a maximum rate of cycles per minute (possibility of overheating, loss of pressure etc.)

    We are starting to get the tuning dialed in for Xplane 11!
    This is my oldest taking it for a spin.

    Nice work. very much like the unit I want to build. My motors are rated 24volt 200 watts continuous and 1200watts peak.I may have lots of questions when I get my build going

    Absolutely! Just let me know.
    I apologize I haven’t been on here much the last few days. I’ve been playing and tuning on the profiles.
    It is so much fun!
