It's back to building at the TF5 hangar after the summer break. Over the past few classes, progress has resumed on various areas of the build. The primary task has been preparing the interior fuselage for paint. This calls for the tedious task of using scotch brite to remove the aluminum oxidation in order to increase the adhesiveness of the paint to the surfaces. The fuselage was then cleaned, masked off, and transported for painting. The fuel tank has also proven to be an important task. Over the last few weeks, the tank has been sealed and tested. As of now, our first test shows that the tank is holding air by the pressure in the balloon. Furthermore, the wing spars have been started, and the ribs are ready for assembly. The structural flanges are currently being riveted, and the tie down attach points have been tapped. In addition, a hinge adjustment to the engine cowl was worked on, and the oil door is under progress.
Stay tuned for more updates soon!
