The Helicopter rig was originally used for sea fishing and later adapted for carp fishing because of its anti-tangle properties.
The rig was named the helicopter rig after its helicopter blade like motion in flight.
The baited hook-link rotates about the main-line axis by the use of the loose fitting hook-link swivel, usually on anti-tangle tubing or lead-core.
The Helicopter rig is probably the most commonly used rig when trying to achieve extreme distances because of its anti-tangle properties and it’s aerodynamic set-up.
The Helicopter rig is best used with a two or three bait ‘Stringer’, a ‘Stringer’ is usually free offerings of your hook-bait that are threaded onto dissolvable P.V.A. string and tied to your hook.
