Rick,
just got back from the field, bird is flying great. I did put it on knife edge, and it does pull to the belly. Not bad though, i can live with it!
It does fly great inverted though. I drilled out the front dowel holes down, about 3/32" then made a new plywood plate ,and epoxied it in behind old bulkhead, to accept dowels, then filled in gap in fuse with epoxy& micro baloon mix. I guess you could sand the rear of the saddle too, six of one half dozen of the other, LOL
Yes, the stab is now flying at level with no down trim!!
Good luck, Paul
