Balancing & Adjusting; Recommended Control Throws - GRAUPNER TANGENT FLAMINGO 2006 Bauanleitung

Although there is a certain amount of Carbon used in the construction of the fuselage, we
would suggest that there is no problem running the antenna down the inside of the fuselage
boom (we fly all our models this way). However, ALWAYS carry out a thorough range test
before flying the model and if any doubt whatsoever then allow the antenna to hang freely.
Tip: Never install the antenna taught, but allow some slack in the wire to allow for small
movements within the fuselage.
The model is now largely complete, but some very important work remains to be done while
still in the workshop.
Balancing & Adjusting.
The correct centre of gravity and longitudinal dihedral are first determined theoretically, and
then confirmed in practice by test flying model.
A successful first test flight is invariably a matter of good preparation!
Start with the centre of gravity at 92mm behind the root wing leading edge – this has been
found to be ideal. You ought to be able to achieve the required balance point by careful
location of the receiver battery (and flight battery in the case of the electric version). Be sure
all batteries are secure as any movement whilst in flight will impact the correct centre of
gravity and adversely affect the proper flying characteristics of the model.
The correct longitudinal dihedral is +1° . This is the angle of the elevator (at the neutral
position) with respect to the wing and is best measured using an incidence meter.
The following recommended control throws have been determined following several test
flights, confirmed by several different model pilots. We strongly recommend that you begin
with the recommended throws and only change them with experience.

Recommended control throws.

The throws are measured at the point of maximum deflection – in millimetres:
Normal Flight
Rudder
Elevator
Ailerons
Flaps
The flaps may be set to move upwards, half the travel of the ailerons for full control of the
trailing edge
Thermal Setting
Ailerons
Ailerons (Camber)
Flaps (Camber)
The flaps should not move with the ailerons, but some model pilots prefer to mix the flaps
with elevator (Snap-Flap) in this mode.
