The only way
to achieve that is with a much smaller radius for the location of the coupling
elements.
I don't know
what your coupler looks like, but I would suspect that it is very close to what
is used on the two rotors.
If every thing
else fails, the Hirth comes with the option for a clutch. And the price is
right.
Hi Richard,
You'll get no argument from me on your logic. Are
you using the stock Hirth coupler? You posted a picture of it once before,
and it looks very similar to the one that comes on the Autoflight drive.
The Autoflight (Centaflex) coupler might be a bit larger in diameter, but it's
hard to tell from the pics. The bolt diameter is about 4.5" on the one I
have.
Since 2 strokes are know to run really rough at low
rpm, it would make sense that they would have soft couplers, and it just might
make life simpler. I may end up with a Hirth drive yet
:-)
