The Wings - GRAUPNER TANGENT FLAMINGO 2006 Bauanleitung

intake of air through the spinner itself, but make sure that adequate cooling is
provided.
Prepare the area where the motor mount is to be bonded to the inside of the fuselage nose
with a course abrasive paper (80 grit) to ensure a good bond. The motor mount should be
installed about 1mm back from the edge of the fuselage nose and installed so as to provide
3° down-thrust and 2° side-thrust (depending upon your choice of drive system). Carefully
position the motor mount in place and secure with a few drops of instant adhesive before
finally bonding in place with a bead of suitably thickened epoxy.
Tip: Fit a long nylon bolt through the centre hole in the motor mount and use the
protruding part pf the bolt as an aid to adjusting the precise amount of down-thrust
and side-thrust. The bolt also serves as a useful handle while positioning the motor-
mount in place.
With the motor temporally installed, fit the propeller yoke and spinner and check the
alignment of the fuselage nose with the spinner. Carefully grind the front of the fuselage nose
to match the profile of your chosen spinner.
Only when the motor-mount is secure, install the motor (remember to use lock washers) and
ensure that the drive shaft turns feely and there is adequate clearances for the propeller yoke
and spinner assembly. For the sake of safety, don't install the propeller until the model is
complete!
Note: Check that the screws used to secure the motor to the motor mount are not too
long as they may otherwise foul the internal motor mechanism. You may find it
necessary to countersink the mounting screws slightly, to achieve clearance with the
propeller yoke/spinner assembly.

The Wings

The wing panels are supplied largely complete and require only the minimum of installation
work and finishing.
Wing / Fuselage Joint
The FLAMINGO 2006 features a floating joiner, meaning that the opening is the fuselage is
approx. 1.5 mm larger than the diameter of the wing joiner. This system is widely used in full-
size aircraft and has been well proven over many years of model design and manufacture.
The main wing joiner consists of a single Ø 10 mm hardened steel wing-joiner which is ample
to carry the flight loads. The fuselage is suspended between the wing panels on four steel
incidence pins.
Work carefully when drilling the holes in the wing roots to accommodate the incidence pins
as these determine then incidence (with respect to the fuselage). Using small screw-clamps,
carefully fix small 3mm thick pieces of scrap Balsa to the top and bottom surfaces of the wing
at both leading and trailing edges. The upper pieces should be positioned to overhang the
wing root by a few millimetres - to act as guides along the fuselage wing fairing.
Position one wing panel carefully against the fuselage fairing at the leading and trailing edge,
using the small Balsa pieces as guides, and tape it firmly in place. Now mark the position of
the holes for incidence pins on the wing root by working through the holes in the opposite
side of the fuselage using a sharpened 3mm steel rod (or similar tool).
