From a friend's experience of most of a season's take-offs/landings on our grass strip---the carbon cloth finishes a bit too close to the back of the U/C mount,and is an abrupt line at 90 degrees to the long axis of the fus.
This resulted in multiple small stress cracks in the glass/balsa laminate just aft of the carbon cloth.
Extending the carbon cloth to the line drawn on the photo worked nicely--no further damage.
