    I didn't fly long enough to see any changes in temperature of the motors. I'm heavy, so they must have some work to do, even if I used 3 gas struts to balance the weight. Right now, temperature / inefficiency is not a problem, but I'll keep that in mind.

    Things are on hiatus for a while because my mother has been in the hospital for 4 months now, with a lot of things I need to take care of. But generally, yes, I'm working on a racing configuration including custom pedals and a joystick/HOTAS configuration. I will create FlyPT presets for the racing/rally games as well as Euto Truck Simulator / ATS.

    I have a single strut, which always pushes a depowered rig to one side. I use the 3D-printed stops included in the package, rotating them in a way that the motor arms stop past the usable motion range but before the red cut-off point. That way, when powered, the rig centers itself. Occasionally, it sits beyond a cut-off point, but then I can see that one of the 3 Arduino's light doesn't come on (it's by design, it's only on when in the usable range), and then I slightly move the offending arm and reset the rig before powering up. Once powered, it takes care of itself.

    Makes sense, I only use 45 degrees as the maximum usable range that SMC3 should allow, beyond which the signal needs to be clipped, and then the emergency stop cut-off implemented. It might be a good idea to limit the actual motion to a narrower angle, but it's done with software.

    Well, family goes first! That's for sure.

    I went VR flying for the first time. Flew >1h and got max. 36°C on one motor. I think I don't have to worry.

    What would you do to reduce the ground behavior a bit. I tried to decrease the longitudinal value of the road noise, but I'd like to get it generally a bit more calm, without decreasing the behavior in the air, which you figured our really nicely.

    And one more question.
    I just set up OVRMC and edited the config to FlyPT. Anything else I need to do, except binding the keys and keeping the window of OVRMC in FlyPT open?

    Thanks so far for all the support. It was a joyful experience so far. And I learned a lot.

    I'm glad the motors are not heating up for you.

    Ground can be controlled by a separate formula in FlyPT Mover. Try to disable "Road Noise" pose completely. If it eliminates what you want to reduce, you can just enable it back and change the gain inside the formula from 1 to 0.3 or whatever works for you. If it's something else, you can decouple air and ground and use a totally separate formulas for them.

    I think you got the OVRMC basics, do fast rolls with it disabled and enabled and look at the spot inside the cockpit close to your head. Note the movement of the head relative to the cockpit. There should be a huge difference between on and off. It's never perfect, partly because your head really bobs from the actual chair movements, but the difference should be unmistakable.

    Can you please share a video of your build? It would be nice to see your completed project in action. Also, I'd appreciate it if you leave a review on the website.

    Alright, I'll try it out. Yes, I can do a video for you and pictures for the community. It's functional in terms of 6DOF, but I still have to think about a suspension for Honeycomb Alpha and Bravo. I commented on Google maps already and will leave a comment on your website as well.

    Hi all,
    here are two pictures of the working rig. One at a development stage without Yoke and the other is a picture from yesterday's with Honeycomb Alpha and Bravo on a little self built desk.

    Let me know, it there are any questions. I flew my home airstrip yesterday in VR and reducing GAIN to 0.3 (Ground Nois) feels so much better. OVRMC is working now as well.

    Next project: The china 24V 1500W power supply is loud as hell. I'll see, if I can upgrade the fans.
