Hello Tomas, I was wondering if you had a chance to look at the vibe analysis files I emailed you back in the last week of July? Regards, Kevin |

Hello Kevin, I am very sorry. Unfortunately the files can't be opened. It require authentification. Can you attach them here, please? Or send directly plots to my email. |

Thank you for the details! Well, it definitively looks like something unbalanced on the rudder. Actually it could be both tail shaft (the most likely) and/or bearings that are holding tail shaft. These are the most common issues (especially after crash). So I would start with the shaft. Bearings can be both verified easily by inserting a shaft inside (only one bearing) and then by rotating with the shaft while radially pushing. It should be absolutely smooth with no crunching. Tail shaft is rather damaged in nearly each crash where tail hitted ground in some way. |
