Translations:KAVAN SLING Mini 616mm - Instruction manual/64/en
Support your model with your thumb and index finger (refer to the figure). The model should be level (or with the nose slightly down) when supported at 50-58 mm behind the leading edge of the wing. You should achieve that with the model as it is, right out of the box. You may correct the centre of gravity location by moving the position of the receiver pack. If necessary add some lead to the nose or tail. It will not spoil the performance of your SLING mini, but she will recognise an incorrect centre of gravity immediately. An incorrectly balanced model is difficult to fly, and might not fly at all!
