Recovered due to digifin malfunction. The following is an email sent to TWRC from David Aragon: Pete, Ben: Waldo, glider 045 has been flying great for 3 weeks on his new digifin, installed new in late August. Version 6.37. After many ms device error aborts since Thursday with digifin taken out of service and no heading control obvious from his sbd\'s we gave up trying to fix it with exit resets and recovered him today. The rudder and entire tail assy look like almost new, but the rudder no longer springs back when you manally deflect it. That is , if I move it to the right rudder stop it moves easily and when i release it it springs back maybe 5 degrees. Same thing to the left rudder stop except even less spring back. Feels like an internal mechanical failure. I\'d be glad to try to service it here or least open it up to give you a better idea of what is wrong. Does TWR consider it field serviceable? Could this just be a loose setscrew type fix?
