How to Set Up a Helicopter Rig

Your lead lands in soft silt or a carpet of weed, sinks in and takes the hookbait with it. A helicopter rig stops that. The hooklink swivel rotates on the line, leader or tubing above the lead, between a bottom stop and a top bead, so where you set the bead decides where the hooklink sits.

The rig came to carp fishing from sea angling. This helicopter rig setup guide builds it step by step and ends with the test that matters most, because the Angling Trust’s best practice guide says a line break must never leave a fish tethered. For other presentations, see the carp rigs hub.

Step 1: Decide Whether a Helicopter Suits Your Swim

On clean gravel the helicopter is often the wrong choice. Over silt and weed it presents where a lead clip struggles.

The helicopter rig for carp suits silt, weed and debris because the top bead can be set high enough for the hooklink to lie on top. With a lead clip, a lead that sinks into silt pushes the hooklink up at an angle, according to Korda’s helicopter rig guide. It also carries the chod rig, letting the hooklink ride up the line over weed.

The cost is hooking: a carp can move further before it feels the lead, so Korda rates the helicopter as less efficient than an inline lead or a lead clip. On clean gravel at short range, one retailer’s guide finds a lead clip often does better.

	Helicopter	Lead clip
Best bottom	Silt, weed, leaf litter, debris	Clean, firm ground such as gravel
Hooking efficiency	Lower: the fish travels further before feeling the lead	Higher
How the lead comes free	Lead release arrangement at the bottom of the leader	Tail rubber pushed lightly onto the clip

For the wider helicopter vs lead clip comparison, read lead clip vs inline lead. If the lead plugs into silt or weed, build the helicopter. On clean, firm ground, start with a clip.

Step 2: Choose Your Line Setup: Leader, Tubing or Naked

Before you buy a single component, find out what your fishery allows.

The components need something to sit on. You have three options:

• Leader. Leadcore or a similar leader, with the bottom stop, swivel and top bead threaded on it.
• Tubing. Rig tubing over the main line, which Korda notes is the usual choice where leaders are banned.
• Naked. Components straight onto bare mono. It works, but the swivel can put pressure on the line at an angle, so some anglers add a few inches of leadcore just above the lead.

Fishery rules come first. The Angling Trust’s best practice guide tells anglers to check what rigs each fishery or club allows, and says local rules take priority. There is no single national rule on leadcore or helicopter rigs, so ask the venue or club before you fish.

Whichever setup you pick, use a hooklength with a lower breaking strain than your reel line where possible, as the Angling Trust recommends. That keeps line lost in snags to a minimum.

Your milestone is a line setup you have confirmed is allowed at your venue.

Step 3: Thread the Components in the Right Order

The order you thread the parts decides whether the rig can release a fish. Get it wrong and no bead or lead system will save it.

Build from the lead end up:

1. Fit the lead arrangement at the bottom of the leader or tubing, so the lead can come free under pressure. Korda describes its Heli-Safe lead release system as able to jettison the lead under pressure. Treat that as the maker’s claim and test it yourself in Step 5.
2. Thread on the bottom stop.
3. Add the hooklink swivel. Korda suggests a size 8 ring swivel with the large ring on the line, so it can pass over a leader knot.
4. Add a detachable top bead. Its bore must match the diameter of your leader or tubing, or it won’t sit and release as it should.
5. Tie the leader or tubing to your main line.

The order matters because of what happens on a break. If the main line parts, the swivel must slide up and off over the top, leaving the fish with only the hooklink and hook, not a lead and leader trailing behind it. Korda gives this as the safety principle the whole helicopter rig depends on.

By the end of this step, the components should be on in that order, with the swivel spinning freely between the stop and the bead.

Step 4: Set the Top Bead for Silt, Weed or a Clean Bottom

The gap between the bottom stop and the top bead does most of the work.

Korda’s rule of thumb is to keep the top bead as close to the lead as is practical, because the nearer the swivel sits to the lead, the better the rig hooks. Over silt, allow extra travel for the depth of the silt, so the hooklink settles on top rather than sinking with the lead. Chods fished further up the line rely on line tension to set the hook instead.

For starting figures, Fishing Again suggests:

Bottom	Suggested travel (one retailer’s starting point)
Deep silt, chod hooklink	About 10 to 15cm
Clean bottom, standard hooklink	About 6 to 10cm

These come from a single source. Feel the lead down on the cast, or drag it back slowly, to judge how soft the bottom is, then move the bead to suit.

You should now have the bead set for the bottom you identified in Step 1: more travel on soft ground, tight to the lead on firm ground.

Step 5: Test That the Rig Fails Safe

Respected carp anglers quoted in a CARPology feature on rig safety said some manufacturers test their clips and helicopter systems thoroughly, while others cut corners. In the same piece, Kevin Nash and Leon Bartropp made the point that any end tackle can be unsafe in the wrong hands. Test your own rig rather than trust the packet.

The independent standard is the Angling Trust Best Practice Guide to Freshwater Angling:

• Use bolt rigs and semi-fixed leads with care, and make sure the leger weight can slip free if it snags or tangles.
• Make sure a line break cannot leave a fish tethered.

Run this two-part test at home, before the rig goes in the water:

1. Pull the swivel up against the top bead. With light pressure, the bead should come off or the swivel should pass over it. If it locks, change the bead or the leader.
2. Check the lead comes free under pressure. On a clip or tail-rubber arrangement, Angling Times’ safe bolt rig advice is to push the tail rubber on lightly so the lead ejects easily.

Repeat the test every time you re-tie. If either part sticks, rebuild before you cast, and follow your fishery’s rules whatever the packet says.

Step 6: Fix Tangles and Missed Takes

The helicopter has two known weaknesses, and both have practical fixes.

The hooklink lands on the leader. Korda notes that underwater filming has shown the hooklink and bait can come to rest on top of the leader or main line, which makes a pick-up less likely. Commonly suggested fixes are a shorter hooklink and a top bead kept close to the lead. Neither is a guarantee.

Takes that don’t hook. The fish travels further before it feels the lead, so close that gap wherever the bottom allows, as set out in Step 4. Use a sharp hook and check the point after every cast.

If you’re fishing pop-ups on the helicopter, the Ronnie rig is one hooklink option to try.

Your finished helicopter rig should present cleanly, with the bead as tight to the lead as the bottom allows. If problems persist, shorten the hooklink and tighten the bead before you change anything else.

Frequently asked questions

Is a helicopter rig safe for carp?

A helicopter rig is safe only when the hooklink swivel can come off over the top bead and the lead can slip free. The Angling Trust's best practice guide says a line break must never leave a fish tethered and the lead should slip free if snagged. Test both, and follow your fishery's rules.

Helicopter rig or lead clip?

Use a helicopter rig over silt, weed and debris, and for chod rigs, because the hooklink can sit on top of the bottom. Use a lead clip on clean, firm ground, where it hooks fish more efficiently. The lead clip vs inline lead guide has the full comparison.

Can you fish a helicopter rig without a leader?

Yes. You can fish a helicopter naked on mono or on rig tubing. On bare mono the swivel can put angled pressure on the line, so some anglers add a few inches of leadcore above the lead. Tubing is the usual choice where leaders are banned. Check with your venue.

What if the carp are feeding up in the water?

A helicopter presents the hookbait on or just above the bottom, so it won't reach carp cruising in mid-water. For fish holding off the bottom, a zig rig is the usual answer, covered in the zig rig fishing guide.
