RE: 4* 40 rudder problem
What did you glue the metal tab with? I have a Four Star and I did it with 15min epoxy. If you used epoxy, you can use a heat gun to unset the epoxy and remove the whole thing to set it right. I've done this with even more complex set ups. I once had to detach a whole stab that ended up crooked on a kit and it worked perfectly. If you can carefully peel the covering from the bottom part of the fuse, just 2" or so, so the heat won't damage the covering, you'll be able to fix it with no apparent marks. Make sure that you thoroughly remove all the glue from the previous attempt before you do it again because when using this method, epoxy tends to get brittle and it could cause a failure in the future.
