Flybar stainless steel 4 x 320 mm

The length of the flybar itself also plays an important role in the model's flight characteristics: the longer the flybar, the smoother the hover. A longer flybar increases the control deflections. 450 mm length is considered normal, while 510 mm provides more docile handling.

Inertia weights for Ø 5 mm flybar

Inertia weights are small "extra brakes". They increase the gyroscopic stability of the flybar and slow down the rotor head's response. For every beginner we recommend these so the responsiveness of the rotor head is reduced. The rotor head becomes more responsive as the inertia weights are moveded inwards (always place equally!). Inertia weights suitable...
