60-Size FAI F3C Control Paddle for D=4mm Flybar - K&S KS1195  [KS1195]

60-size F3C control paddle overview

This control paddle is an RC replacement part made for 60-size FAI F3C class helicopters that use a D=4mm flybar. It serves as the mounting interface between the swashplate/cyclic linkages and the flybar or tail link, providing a stable attachment point for rods and ball links used in collective and tail control.

Installation is straightforward for hobbyists familiar with swashplate and flybar linkages: remove the worn paddle, preserve correct rod lengths and ball link orientation, then fit the new paddle with the original hardware. After fitting, inspect free play and linkage geometry to confirm neutral pitch and correct cyclic throws before full flight testing.

During trimming and setup this paddle helps keep control geometry consistent. It assists in pitch curve tuning and tail gain adjustments to maintain predictable response across collective travel and cyclic inputs, useful for both practice sessions and precision flying.
