The helicopter wobbles on aileron and elevator axis.

Reducing the swashplate gain does not help to suppress this effect completely.

• The helicopter's linkage ratio is not suitable for flybarless usage. In SETUP MENU point J adjust the cyclic pitch to exactly 6.0 degrees and make sure the color of the Status-LED lights up “blue”. If this is not the case change the mechanical linkage ratio of the helicopter (i.e. by moving the linkage balls further inwards on the servo horns, by mounting longer linkage balls on the swash plate outer ring or by mounting shorter linkage balls on the swash plate inner ring).
• The servo-blade combination is not good. Use faster and stronger servos and/or specific flybarless blades.
• Some linkages aren’t moving smoothly and freely. Check the mechanics for any hard points (ball linkages, blade grips). Check if the dampers are greased and that the thrust bearings in the blade grips are correctly mounted.
• Imbalance of the main rotor head. Firstly, do not tighten rotor blade bolts to much. The blades must be able to align themselves by centrifugal force. Then check blade balancing and/or try a different set of rotor blades.
