Flying
Tie the wing to the fuselage using the supplied rubber bands. Add ballast as necessary in order to achieve the correct position of the centre of gravity (CG). Support the wing of the model with your fingertips in the point marked "" on the fuselage plan. The fuselage should be level - if the nose pitches up, add more ballast into the nose. If the tails pitch up, remove the ballast. Free flight model: Place and secure the appropriate ballast in the nose. If you intend to enter an F1H (A1) contest, you will have to add additional ballast into the CG position in order the all-up weight of your model was higher than 220 g. RC model: Try to place the receiver battery, servos and receiver in such a manner the correct CG position was achieved without adding any ballast at all if possible.
Free flight model: Secure the protruding piano wire push rods to their outer tubes by a strip of sticky tape in the cockpit. This will allow trimming the model if necessary, whilst the position of control surfaces remains fixed.
Choose a nice, calm day for the first flight of your Der Mini FALKE. The flying field should be a flat, grassy site; free of power lines or other obstacles. The model must be launched into the wind every time. Throw grass into the air to observe the wind direction. Hold your model with the wings and fuselage level. Launch your model with a gentle push straight with the nose pointing slightly down. Do not throw your model with nose up, or at greater angle than 10 degrees down. The model must have a certain minimum speed from the very start to stay airborne. It is not enough to just place your model in the air. It is better to land in tall grass in order to prevent any damage to your model during initial trimming.
