MD500D / MH-6 "Killer Egg" · Round nose
Looks like an egg.
Strikes like a beast.
Faithfully replicating the iconic 160th SOAR "Killer Egg" — high-precision scale detail, tactical weapon mounts, opening cabin doors, and painted operators riding the side benches with their legs over the edge.
Ready to fly out of the case, with a GPS flight system that holds position and brings it home on one switch. The round nose everyone wants and almost nobody builds — not the pointed MD500E.
BuiltFactory assembled and test-flown. No kit, no build time, no setup — it comes out of the case as a finished aircraft.
PaintedAirframe and crew figures both arrive fully finished. No primer, no brushwork, no decals to apply.
FlyingGPS, altitude hold and return-to-home are already tuned. Charge the pack, arm it, and go.
Diorama-grade realism
Diorama-grade, not display-shelf-grade
Most "scale" RC helicopters look convincing from three metres away and fall apart the moment you pick one up. This one is measured off the real aircraft at 1:16 and detailed to hold up in a photographed diorama — crew loaded, doors open, at arm's length.
First in its class
Doors that open onto a real interior
Working scale cabin doors reveal a modelled cockpit: seats, instrument panel and cyclic sticks, all moulded — not a printed sticker anywhere. Open the doors on the shelf and the aircraft still reads correctly.
Correct to the prototype
Five-blade rotor head
The real 500D carries a five-blade head, so this one does too — a variable-pitch scale head rather than the two- or three-blade compromise most models in this size settle for. It's the single detail scale purists check first.
Lighting
Scale navigation lighting
Working lights in the correct positions, which is what sells the illusion at dusk — and what turns a hover into something that looks like an actual aircraft operating at night.
Airframe
Every line redrawn at 1:16
Fuselage, landing skids, antenna array and troop benches were all developed from scratch for the round-nose profile — 485 mm long, 190.6 mm tall, 430 mm rotor. Nothing is borrowed from an MD500E shell.
Crew
Figures that match the mission
The military version carries 6 operators, seated along the benches with their legs over the edge — the pose that made the Little Bird famous. The civil version carries a pilot and one passenger, because that is what a charter 500D actually flies. The figure count is part of the scale, not a package tier.
Markings
Nothing to apply yourself
Service titles and blade tip colours are already on the aircraft when you open the case. No decal sheet, no alignment, no silvering, no ruined afternoon.
Hardpoints
Tactical weapon mounts
Scale mounting points on the fuselage sides, the way the armed aircraft carries its stores. It's the detail that turns a round-nosed transport into the thing the nickname is actually about.
Canopy
Clear enough to be the point
The bubble is genuinely transparent, not tinted plastic hiding an empty shell. Everything behind it was built to be looked at — which is the whole reason a round-nose model beats a pointy one on a shelf.

The details people look for
- Five-blade head — correct for the D model, not the four-blade OH-6 rotor
- Half-sphere canopy with no MD500E point anywhere on it
- T-tail with endplates, in the right proportion
- Cabin doors that open on both sides
- Moulded seats, instrument panel and cyclic sticks — no printed detail
- Side benches sized for seated figures, not decorative
- Scale antenna array on the boom
- Skid geometry taken off the real aircraft
- Blade tip colours correct per livery
- Service titles already applied — no decal sheet
- 485 mm long · 430 mm rotor · 190.6 mm tall, all true to 1:16
- Cabin sized for genuine 1:18–1:25 figures
The cabin and benches take any 1:18 to 1:25 figure, so you can build a specific scene — a fast-rope insertion, a medevac, a two-up sightseeing flight — rather than flying an empty shell.
Flying it
A scale heli you don't have to be afraid of
A 250-class collective-pitch helicopter normally demands an experienced pilot. This one carries a full GPS flight controller, so the aircraft handles the parts that destroy other people's models.
It parks itself in the air
GPS, compass, optical flow and a laser rangefinder hold position and altitude together. Let go of the sticks and it stays where you left it — which is what makes a low, slow scale pass possible instead of terrifying.
It comes home on one switch
One-key return-to-home, plus automatic return on low battery or lost signal, one-key landing, and a geofence you set yourself. Three separate ways it recovers itself if the flight stops going to plan.
You don't have to wait for a dead-calm morning
Three metal-gear servos and a dedicated brushless tail motor keep it tracking where you point it rather than weathervaning. A breezy evening is still flyable — roughly doubling the days you get to use it.
It tells you before it becomes a problem
The controller screen shows battery, altitude, distance and satellite lock live. You bring it home because the numbers said so — not because it went quiet 60 metres out.
Straight answer: GPS makes this far more forgiving than a bare scale heli, but it is a variable-pitch helicopter, not a toy quadcopter. First flights in GPS mode, open space, no figures loaded. 18+.
FPV — "with FPV" versions
Two places to put the camera. Your call.
The airframe takes the camera in either position, and you can move it between them. They give you two completely different kinds of flying.
Position 1
In the cockpit
Mounted in the centre of the pilot's seat position, looking out through the clear canopy. This is the scale option — the view a pilot would actually have over that round nose, with the panel in frame. Best for immersion and for footage that looks like the real thing.
Position 2
Under the battery
Mounted low on the belly for a wider, more downward field of view. Easier to keep your bearings while you're still learning the aircraft, and the better choice for filming ground features, following a subject, or shooting terrain.
The screen is already in the controller
No phone clamp, no goggles, no app to pair. Switch on and the feed is in your hands — 5.8 GHz, 200 m+ live. That's the difference between using FPV every flight and using it twice.
Skipping it now doesn't lock you out
Every airframe leaves the factory with both mounting positions and the video port already fitted. Buy without FPV and change your mind next year, and you're adding a camera — not cutting into a finished fuselage.
First batch only
The figures are free.
Only on the first batch.
An empty Little Bird is just a helicopter. Operators on the benches with their legs over the edge is the image — the one you've seen a hundred times and the reason you're on this page.
Every first-batch pre-order includes them free: six painted operators with the grey/black aircraft, or a painted pilot and passenger with the orange. Finished, ready to load, nothing to do.
Once the pre-order window closes, the figure set becomes a separately priced accessory. There is no second chance at this on a later batch.

Choose your livery
Two liveries. Different figure counts. Read this first.
Identical airframe, identical electronics, identical flight system. What changes is the paint scheme and how many painted crew figures are in the box.
Colour: Black
Tactical Grey/Black
A matte grey-black airframe carrying U.S. ARMY titles in white, with yellow-tipped main blades. Six painted operators ride the side benches with their legs hanging over the edge — olive fatigues against a dark fuselage, the exact silhouette a real MH-6 makes on an insertion.
6Painted operators
included
Colour: Orange
Orange Stripe Scheme
Bright orange with yellow and dark brown striping down the flank and across the tail, finished with red-tipped main blades. It's the unmistakable look of a working sightseeing 500D — the scheme a whole generation recognises from 1980s Hawaii television.
2Pilot & passenger
included
Why the figure counts differ: because the real aircraft differ. An MH-6 on a special-operations task carries a squad on its side benches — so the military version ships with 6 operators. A civil 500D on a charter flight carries a pilot and a passenger — so the civil version ships with those two. We matched the figures to the mission rather than to the price. Figure count is the only difference in package contents between the two colours.
About the figures: they arrive fully painted and ready to load — no assembly, no brushwork, nothing to buy. Want a fuller cabin — especially on the Orange version? The cabin and benches take any 1:18 to 1:25 figure, and we stock additional painted pilot and operator figures separately. This free bonus ends when the pre-order window closes; afterwards the figure set becomes a paid accessory.

Before you pick a version
Three quick answers
Every version is a complete aircraft — airframe, radio, battery, charger and blades are in the box no matter what you choose.
Which colour?
Grey/black if you want the special-operations bird with six operators on the benches. Orange if you want the civil sightseeing scheme with a pilot and passenger. Same aircraft underneath; only the paint and the figures change.
Do I need the FPV version?
Not if you already own FPV gear. Every airframe ships with the camera bay and 5.8 GHz video port already fitted, so you can mount your own camera and use your own monitor or goggles. Buy the FPV version if you'd rather it was done for you — it adds the camera plus a controller with the screen built in.
How many batteries?
One pack flies 15–18 minutes and then charges for an hour. If you drive anywhere to fly, take two. Three if it's a club day or you're filming. Extra packs are cheaper bundled here than shipped on their own later.

Before you order
Questions we actually get asked
I've never flown a collective-pitch helicopter. Can I fly this?
With realistic expectations, yes. In GPS mode the flight controller holds position and altitude for you, and return-to-home recovers the aircraft if you get disoriented — that removes most of the ways beginners destroy a scale heli.
What it doesn't remove: this is a 485 mm aircraft with five spinning blades and real momentum. Fly it in an open field, not a back yard. Learn hovering and gentle circles before you try scale passes. If you have never flown anything, spend a few hours on a cheap simulator or trainer first — it will save you the cost of a fuselage.
What happens if I crash it? Are spare parts available?
The shell is hot-runner moulded composite with deliberate flex, and blades are nylon/carbon rather than brittle plastic, so light knocks usually cost you nothing. Harder impacts typically take blades, the canopy or the skids first — the parts designed to give.
Replacement parts are supported through our Replacement Parts Center. If you damage something, email service@stirlingkit.com with a photo and your order number and we will identify the part for you.
Do I need to buy anything else to fly?
No. Every version ships ready to fly: aircraft, transmitter, battery and charger are all included. The "with FPV" versions also include the camera and the monitor-equipped radio, so there is nothing to source separately.
The only thing worth adding is a second battery — see the configuration table above.
How long does it fly, really?
15 to 18 minutes per pack, measured with an empty cabin. Load six figures and the extra weight will cut into that. Recharging takes about an hour on the included balance charger, which is why most owners order two or three packs.
When exactly does my pre-order ship?
The pre-order window runs until August 15, 2026, and the first production batch ships before mid-August 2026. Orders are fulfilled in the sequence they were placed, so an earlier order means an earlier slot in the first batch.
If the schedule moves for any reason, we email every pre-order customer directly rather than waiting for you to ask. Production status is also posted on our Production Updates page.
Honest notes before you commit.
This is a pre-order. You are reserving a unit from the first production batch, not buying from stock on a shelf.
Stated flight time, control range and video range are measured in open conditions with no obstructions. Buildings, trees, interference and wind will reduce all three.
Check your national aviation authority before your first flight. In the US that means the FAA's recreational flyer rules, including registration and the TRUST safety test — this aircraft is well over the 250 g threshold.
Not a toy. Recommended for ages 18+. Lithium batteries are shipped in accordance with carrier regulations, which may affect available shipping methods to some destinations.
Put it on the shelf with the doors open and the team aboard and it stops being a model. That bubble reads like glass, the panel reads like a panel, and six operators sit along the benches the way they've sat in every photograph you've ever seen of one of these.
Then you take it outside. It comes off the ground, the nose tips forward, and six pairs of legs swing out over the skids.
That's the moment. That's what you're actually buying.
