Техническая Спецификация для Conrad Energy RtF 900 mm FMS064

The model must be set by proper placement of the flight battery (and, if required, by addition of trimming lead) so 

that the centre of gravity is approx. 48 mm behind the nose strip of the wing. 
To do so, mark the corresponding centre of gravity position at the bottom of the wing with a pen. From the bottom, 

hold the assembled and ready-to-fly model at the measured positions with your index fingers (or a corresponding 

device). 
If the centre of gravity is set correctly, the model should be leaning slightly forward.

 

Always measure the centre of gravity completely ready to fly (inserted flight battery, attached cabin hood).
