From KAVAN RC Wiki

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 wing 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.
