If the rudder deflections have been set according to the assembly instructions, the following has
occurred method to control of Center of Gravity meanwhile proven:
1. Stable and steady circling flight with fully pulled elevator
2. When the elevator is fully pulled, aileron is fully in the opposite direction
3. Quick, correct reaction - focus too far ahead
4. Sluggish, correct reaction - focus ok
5. No or opposite reaction - focus too far back
Depending on the weather and the desired reaction speed, the flyers so quickly to a meaningful
center of gravity close to the maximum performance check out.
4.4 Rubber rope high start
After the manual starts, the elevator will be in neutral position for the following rubber rope starts
reduced to approx. + 0.5 mm (see flight phases). For the first attempts at startup, the hook should be
set so that it is approx. 5 mm in front of the center of gravity. During further flight tests and
optimization, the hook position can gradually be adjusted be laid at the rear. Optimal high take-off
heights are only achieved with a hook position behind the center of gravity reached. If there is more
than 2 mm of hook back, the starts are still safe, however significantly more course corrections are
necessary. As usual with RES, the RES-Dart is thrown upwards at the start of the rubber rope. To
