Neil: I got it wrong the propellor flange and ringgear flange is not the same.
Can’t figure it out ? how the ringgear side flange is stuck to the hollow shaft.Seems to me it has thread that screw in. Somehow it must be locked. I did not removed the pilot bearing as there is no need to do so as it is still brandnew never been used.
The propellor flange has 3 pins that holds it in place after the pressfit.
The hollow shafts needle bearings ,run over the oil holes in the shaft, and there is some holes between them too.


This psru is counter rotating and a 2,17 : 1 ratio.Therefor needs an anti - clockwise prop pilotside view. I am planning to put in just a 6 pinion planet steel casing planetary No other modifications to be done.There is a  6 pin planetary with 12 lug available to drop into the housing.
I believe with the 2  - 44 mm p ports @ 6500 rpm will have sufficient Hp for take off and climb turning the prop at 2900 rpm.
The at “top of climb “ level out and cruise at 2300 prop rpm.
