I was interested in your comments as I recently lost a Goldberg Ultimate for a similar reason. I lost it during a spin that I could not get it to come out of. Later inspection shoewed the kevlar was cut through where it was riding on the rudder connector. Just set up a pull/pull rudder on my H9 Edge but did not use the Kevlar, going with the plastic coated steel cable and you can bet I will check it out from time to time.
