Iāve only just noticed this thread and I find it very interesting because it brings together actual user experiences of my most expensive ātoysā in my quest for immersion in flight sims, (XP11 and MSFS).
Although Iāve never been brave enough to gamble on being a backer, Iāve spent barrowloads of cash on VR headsets and motion platforms.
I havenāt commited to a yawvr 2 yet (luckilly !), but have been using a Yaw1 pro and DOF Reality H3 and H6.
Each has itās Pros and Cons, hence me still having the DOF rig and the Yaw, as I canāt decide which to keep. Maybe the Yaw2 will be a succesful blend of the two devices.
The DOF rig works better with my other Flight and Driving Sim hardware, whereas the Yaw 1ās much more extreme movements (even with the yaw axis restricted) neccessitate it being mounted in the middle of the room and used exclusively with a VR headset. Itās also quite low down for screen use anyway, even with the low wheeled platform I made for mine.
The DOF rig is superb for driving sims, but Iāve never managed to get smooth subtle pitch and roll movements because of the rotary wormgear/pushrod actuation method and the basic design of the centre of weight being much higher than the pivot point, so when youāre leaning over fully in any direction, your weight is then way off balance.
The Yaw 1ās hemisphere on rollers is a brilliant way round the problem, since the riderās weight remains much closer within the bowl, keeping a much more constant loading on the driving rollers, so smooth movements in flight sims are better, and over a much greater tilt range. It does have to be kept as light and compact as possible though, to avoid extraneous addons (like heavy pedals or wheels), can introduce inertia overrun, with their kinetic energy being so far from the central pivot.
The Yaw2, having the same roller based curved mechanism, rather than linear or rotary actuators intrigues me. Iāve never been able to try one out, but it could indeed be a good compromise between the conventional seating position of a DOF rig but with the increased range of motion of a YawVR. Though it is a thought at the back of my mind that with the rider sitting so much higher above the rotation axis (unlike the Yaw1), it must be working quite hard to bring the rider back upright after leaning them over at 45 degrees.
