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. This fixes CG issue, but are there other concerns with doing this? Would be interested in experience of others.

Other than the max allowable weight of non lifting parts there should not be any other issues if the repair was solid. Added weight in a tail boom repair (long tail moment) takes several times the added weight when added to the shorter nose moment. Having to add so much weight forward of the cg though shows that a sloppy and probably excessive repair was made.
