The sanding batten on the
trailing edge of the tail unit and
the Edge of the table. So grind
we the trailing edge down to

sides (approx.1mm) pointed.In
contrast to the trailing edge, the
we just sharpened it to a point
we grind them The leading edge
of the tail units is round.For this
we grind on both Sides of the
leading edge of the Tail unit a 45
° phase, which is approx.a third
of the wood thickness occupies.
This phase helps us again, an

To sand the rounding over the entire edge curve. When smoothing the rounding ismake sure
that there is actually a curve at the end. A pointed oneThe leading edge of the tail unit would
have a negative impact on flight characteristics.At the end all that is missing is the bevel for
the rudder deflection. Located by the elevatorthe bevel on the underside of the rudder, at
the rudder on the left side,where the rudder horn will later be located.The bevel in the
elevator must be sufficient to allow a deflection ofto reach at least 12mm downwards. The
rudder must be at least 45Degrees of deflection in both directions.We also explain the
grinding of the tail unit in detail at the end of our 4th
