Mounting the elevator to the fuselage
Cut
the sanded
elevator into
two
parts.
Sand
the
hinge line
wedge-
shaped
analogous
to the rudder and
harden the hinge
edges with super
glue.
Sand the carrier for the elevator aerodynamically on both
sides and
round on the top
, so that the
boom fits
precisely
. Glue the lever a little bit moved to the side.
Fix the carrier first to the elevator and then to the boom:
Attach the elevator softly with a drop of super glue first and
check the
correct alignment
:
-
The elevator is positioned
1 cm in front of the rudder
.
-
The elevator must be
horizontal
. You can check this
best by mounting the wing and looking on the model
from the front.
-
Die
EWD
(angle between wing and elevator) must be
2°
. Normally, the angle results automatically, if you
mount everything correctly. Nevertheless you should
check the angle before you glue everything. Proceed
according to the drawing below:
If the
wing
is positioned
horizontally
, the
leading edge of
the elevator must be 2mm lower than the trailing edge
.
Strengthen the joint between elevator and boom with
carbon rovings or glass fibre (1x 50g/m²)
. You can find
shape templates at the end of the instruction or in the
attachment. You can glue the strengthening with super or
epoxy glue.
