Flysky NB4 Noble Rear Steer Knob – Achieve precise one-handed rear steering while keeping full control of your Flysky NB4, NB4+, or NB4 PRO. Ideal for programmable servos with 255° rotation or more, this knob reduces rotation from 270° to 70° with maxed-out servo and NB4 endpoints, providing faster, more responsive steering and unlocking the potential of using a rear steer knob.
