A new weight and balance, after a tail boom repair, shows that several tens of pounds of trim weight needs to be added to a forward location in order to move the CG back into acceptable range.

Thanks for suggestions. The repair (and the weight and balance measurement) was done some time ago. The concern arises because of a new pilot with different weight and preferred CG location. Sounds like a reweighing is in order and also a check to see if there is already trim installed.
