That's good to hear 
, a 12 month wait would seriously cramp my enthusiasm !
I've had DOF rigs for three years now, originally an H3 and now an H6, extensively modified.
They are great for car sims, but they have a problem with flight sims. The direct drive motors suffer from "cogging", because of the much more subtle pitch and roll movements.
The newer SFU gearboxes greatly improve the smoothness, but the jerking during what should be perfectly smooth angle changes is still an immersion breaker. They use simple 24v DC brush motors, so the default direct drive motors jerk around the commutator segments when making very (very) slow are partial revolutions.
There is a DIY solution though. A clever Guy on the Facebook DOF Builders group hit on the idea of swapping the direct drive motors for 4:1 planetary geared motors. So the motor shaft turns 4 times faster for the same degree of SFU "lift". I did the mod on my H6 and it is now beautifully smooth, even when the MsFS or xPlane autoplilot is making barely perceptible movements, (which previously jerked badly).

Here's a video of my DOF Reality H6 motion platform after being modified with Planetary Geared Motors to eliminate the jerkiness during subtle changes in pitch and roll. This is caused by "cogging", where the motor steps from one commutator segment to the next when making partial revolutions. This spoils the immersion, especially in VR, becaus...
