You are right Joe, but the taper denominator is, metric taper 10:1 . It is used in lots of power transfer taper joints. All Rotaxes, Kawasakies and lots of other small engines, aircraft and others, are using it. I am using it on the single rotor too.

Hi George,

Not Ed, but if my trig is not too rusty the angle should be 5.710593 degree.

Ed,

I measured the taper of the flywheel taper with a ruler, the draft is 3mm in 30mm. I checked that with a dial indicator and it was correct - how does one derive the angle of that?

Is it 6 degrees?
