I probably should stay out of this since I have only

pitch line force is set by the diameter of the sun
gear, and that same force (less some friction) is
handed around the total gear set. Under the laws of
adversity :-) the loads are not evenly split between
the planets - so 3 are generally less than 3 times as
strong as 1.(This is why the whiffle tree was
invented, to catch the horse that was goofing off) and
the planet system does not have full "whiffle tree"
characteritics. Still easily the strongest system for
it's size - Vance

Exactly right Vance. Send me your address and your button will be on it's
way.   Correct about the distribution of the load as well.  This unballance
of load is minimized in my drive by using the splined drive (which has a few
thousandts of play) on the ring gear which allows it to float to the best
possible load match.

The Ross design lets the planet carrier float
in milled slots and Ford made the planet carrier out of low modulas 
elasticity aluminum allowing it to deflect somewhat to equalize the 
load in all four pinions. This is not true for the Chrysler and
GM designs.
