GRAUPNER PILOT Bauanleitung Seite 35

Test-flying
Please wait for a day with flat-calm conditions for the first flight. Carry out a final check, then
push the glider forward gently into any breeze, with the wings level and the nose slightly
down. If the glide is steep, remove a little ballast from the fuselage nose until the model
glides at a shallow angle. If the model stalls, i.e. repeatedly climbs sharply, then falls, a little
more ballast is needed in the nose chamber. When adjusted correctly, the model will glide
for a distance of about 15 to 20 metres.
Tow-launching
We recommend the use of the plastic towline handle (Order No. 156) for tow-launching.
The towline handle features an integral return pulley, which makes it easier to launch the
glider when there is no wind. Engage the towline, and ask a friend to hold the glider with its
wings level and the nose angled slightly up. Trot forward into the wind holding the towline
handle, and the model should rise up the line until it is directly above you. If you have built
and balanced the aeroplane accurately, it will climb swiftly like a kite, and drop the towline
automatically when overhead. If the glider veers to right or left on the towline, slow down
and observe whether the model straightens up again by itself. If not, let go of the towline so
that the glider releases the tow.
Any veering tendency should be corrected before the next launch by adjusting the rudder in
the direction opposite to the turn. If you find the model needs a large rudder deflection, then
there is a warp in the model somewhere, and this must be corrected back at the workshop.
If you have to do this, you will need to repeat the test-flying procedure.
Practising the tow-launching procedure is loads of fun, and eventually you will learn the
best method of bringing the PILOT up to full height.
We all hope you have many hours of pleasure and fun building and flying your PILOT.
