Mine broke in the same place; the weld between the right pedal upright and

That's the weakest point on the KR setup and really only a problem on
tail draggers with the added stress of the tailwheel on ground
handling. The cable attach point on the pilots left side has the cable
attach point without going through any weld joints. The right pilot
pedal has the stress going through two welds from the pilot's foot to
the cable attach point with top or bottom mount setup. With the stress
of ground handling from the tailwheel the tubing flexes on every right
foot movement and with the light weight of the tubing something is bound
to break as in both our cases. Grass strips may add to the ground
handling stress as you fly from grass and I frequent grass often.
Simple gussets would fix the problem. If you carry passengers often
that do ground handling it would be the passengers left foot pedal that
goes to the pilots left pedal where the cable is attached that is the
weak point.
