Renew Trigger Response on the 4VF with Futaba Components

The Futaba Trigger Spring Hook and Swing Arm Set tailored for the 4VF transmitter gives a straightforward way to repair worn trigger mechanics and recover consistent control feel. It is useful for model pilots and drivers who rely on dependable trigger action.

Mechanical Benefits

These parts recreate the intended trigger geometry, restoring correct spring tension and swing arm movement. The result is reduced free play, more predictable return, and steadier input for fine throttle or trigger commands.

Assembly Advice

Always power down the transmitter before servicing. Remove the old spring hook and swing arm and replace them with the Futaba set, checking that each element is correctly aligned and secure. Post-fit testing ensures a safe return to activity.
