Thanks Foamaholic. I have yet 1 other question I forgot about. I have seen that the Tribute, similar plane has trouble with the elevator joiner failing. I have already completed that task on the Ultimate. Any ideas on strengthening it? I had though about a tooth pick in addition to the balsa joiner glued into the foam elev halves and to the joiner itself. I have also considered staples between the foam and balsa joiner glued to both. Anyway any ideas would appreciated.
