GRAUPNER DISCUS 2CT Building Instructions page 22

The Centre of Gravity range is between 62 and 72 mm, measured from the wing root leading
edge. Add ballast weight (Order No. 536) to the extreme nose to achieve this. Check the CG
by supporting the model under both wing roots on two fingertips; when correctly balanced, it
should hang level when your fingers are at the stated position.
Flying
We recommend that you test-fly the model on a day with little or no breeze. A large, grassy
field, sloping gently into wind, forms the ideal flying site. Check that both the control surfaces
are at centre.
Push the model forward, directly into any wind, with the wings and fuselage level.
Trotting forward for a few paces gives the correct launch speed. Keep the model flying
straight ahead with minimal rudder and elevator corrections as necessary. If the model does
not fly straight and level by itself, use the trim sliders located below and next to the
transmitter sticks to correct unwanted tendencies. Always land the machine on the glide
(motor stopped), heading exactly into wind. Reduce the model's airspeed just before touch-
down by progressively applying up-elevator to flare out. Always land straight into any wind.
All of us at GRAUPNER Modellbau hope you have many fine flights with your new DISCUS
2CT.
