RE: nitroplanes mrs dara
As more of the DARA's start to be flown, some have had issues with the supplied wing tube. It is recommended that you insert a wooden dowel or another carbon tube into the center of the original tube to strengthen the main tube and prevent wing failure.
Jerry Small and I designed the Miss DARA for Nitroplanes, and I wish they had used what we had designed for the main spar. They did not and now there is some issues. Please use caution and care with the original spar tube.
