FLIGHT MANUAL
4.5.3 Flight
a)
Propeller retracted
The powered sailplane has pleasant flight characteristics and can be flown
effortlessly at all speeds, loading conditions (with or without water ballast),
configurations and c/g positions.
As the elevator trim is linked to the flaps, it should be set such that there is
no load on the control stick at a speed of about 110 to 120 km/h (59-65 kt,
68-75 mph) with flaps set at "0".
The green knurled knob is then opposite the green marking on the edge of
the seat pan cut-out. Then the aircraft is practically always well trimmed for
all other flap settings and for optimum performance within their speed
range.
With a mid-point c/g position the speed range covered by the trim is from
about 65 km/h (35 kt, 40 mph) with flaps set at "L" to about 240 km/h
(130 kt, 149 mph) with flaps set at "S1".
The controls are well harmonized – reversing a turn from +45° to -45° is
possible without any skidding. Ailerons and rudder may be used to the
limits of their travel.
