I suspect most of us are building based upon sierra donors which also have a donut in the drive shaft but which we through away when we fit a reduced
length prop. So this should give you an answer.
The origial Sierra prop didn't have a rubber donought (see the Haynes book of Lies).
I suspect its more for smoother drive and less jarring thought the transmission.
I have heard that the donut is used as a flywheel to give smoother gear changes

what is the diameter of the tubing your prop is made from. in all likely hood if its only a meter use a 1 part prop since your building a competition car for racing. i know that the works rs2000's had a single part prop while the road going models had a 2 part prop, which would indicate that a single part prop is better for competition cars. as for the rubber joint i'd personally rather use a uj especially in a high power/competition car as they give a more direct response and therefore more driver intended control
some interesting spellings of doughnut - maybe you think it will do nought....
The donuts are a tight fit in a locost tunnel but they do fit (I have one) and are a much cheaper (and arguably more effective) alternative to a TRT
prop.

the gearbox that ive just got was out of a sierra 1.8 and it had a donought on the prop just behind the gearbox.
