Balancing the ALPINA 3001 CHAMP PRO
Support the completely equipped, airworthy model, right and left next to the fuselage,
about 84 mm behind the root wing leading edge. The model should now balance
itself horizontally, or as the case may be, the nose pointing slightly downwards. If
additional nose weight is required, use a measured amount of Lead (Lead shot is the
most convenient form) and fix it into the nose with suitably thickened epoxy resin
.
The correct longitudinal dihedral (decelage) is +1 to +1,3°. This is the angle of the
elevator (at the neutral position) with respect to the wing and is best measured with
the aid of 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
.
