Grinding of fuselage and tail unit:
When sanding the hull, we start, as just mentioned, with the transition from the Hull boat
to the hull outrigger. For this, the fuselage boom must be taped off Avoid damage caused
by grinding. Be careful here: if the CFRP tube of the fuselage boom is damaged by the
grinding, a Predetermined breaking point.
First, the end of the fuselage is adapted to the contour of the fuselage. We use a Sanding
lath with grit 150.Tip: Sanding laths can also be easily built from the balsa leftovers on
which we apply the Glue on the respective sandpaper.In order to get even curves on the
desired fuselage edges, we grind at this first 45 ° phases. These phases are easier on
consistency too control and help us maintain a uniform radius.When the desired hull shape
has been created, all wooden parts are made with a finer sandpaper (approx. 240 grit)
sanded again to make it smoother Surface
