I'm going to answer ONE question only; Tom's.

The TRB's (taper-roller-bearings) in the MTX-75 are there for taking the induced thrust on the differential from the thrust component created by the helical gears on the ring-gear differential and the induced thrust from the helical gears on the speed reduction shafts too - THAT IS ALL (it is the nature of helical gears as I am sure you would know). Zero thrust comes from the input shaft to the transmission. I know TRB's, it's my job.
