🇺🇸 U.S.A. FIRST

Ares Acres LLC is a U.S.-based authorized DJI Agras reseller supporting American agricultural drone operators with genuine DJI Agras OEM replacement parts, accessories, and field-ready inventory.

FREE & FAST Shipping is included for all U.S. customers.

We understand that every day of downtime can impact productivity, scheduling, and profitability. That's why we focus on providing fast fulfillment, responsive customer support, and reliable access to the parts operators need most.

Airframe panels are the parts nobody thinks about until one splits. The post-body shell is not a component anybody buys with enthusiasm — it is bought because a panel cracked, a bay took water, or an aircraft came back from a hard landing and somebody looked properly. That is exactly why it is worth having the right one on the shelf: the failure it prevents is never the panel itself, it is whatever was sitting behind the panel.

We ship the Post-Body Shell fast to the U.S.A.

🔧 Component Overview

The Post-Body Shell is the main aft body section of the T50 airframe — the rear counterpart to the front body shell, forming the enclosure and aerodynamic surface for the back of the aircraft. It is a large structural moulding, so like its forward twin it fails progressively, and the useful moment to replace it is early.

The Post-Body Shell supports:

• Correct fitment on the aircraft
• Restored factory function
• Reliable day-to-day operation
• Reduced unplanned downtime
• Simple direct-fit installation
• Fleet parts standardization
• Field-serviceable maintenance
• Predictable service intervals
• Full compatibility with the DJI Agras system
• Increased aircraft readiness

Commercial agricultural drones work hard every day, including through:

• Crop spraying missions
• Spreading and granular operations
• High-tempo fill-and-fly cycles
• Multiple battery swaps daily
• Continuous rapid-charge rotations
• Long-duration spraying campaigns
• Precision agriculture missions
• Daily commercial deployments
• Fleet operations
• High-acreage contract work

Throughout these operations, this is routinely exposed to:

• Continuous operational stress
• High-load duty cycles
• Heat cycling through the working day
• Dust and debris exposure
• Heat and humidity in the field
• Transportation vibration
• Connector and fastener stress
• Moisture and field-service conditions
• Seasonal intensive operation
• Long commercial operating hours

The Post-Body Shell helps maintain:

• A sealed, weatherproof equipment bay
• Correct airframe geometry and panel fit
• Protection for the wiring and boards behind it
• Structural integrity at the mounting points
• Aerodynamic surface continuity
• Resistance to chemical and UV exposure
• A professional appearance on customer sites
• Full aircraft airworthiness after repair

Agricultural chemistry is unkind to plastics. Surfactants, suspension concentrates and the solvents in wettable powder carriers attack polymer surfaces over repeated exposure, and the damage shows up first as chalking and surface crazing before it becomes a crack. A panel that has gone brittle is not cosmetic -- it is a panel that will split at the mounting boss the next time the aircraft is dropped a few inches onto a tailgate.

Fitting and service context.

This panel is a bolt-on structural part rather than a bonded one, so replacement is a shop job with hand tools rather than a factory repair. Work with the aircraft powered down and the batteries out, support the airframe so it is not resting on the panel being removed, and keep the fasteners organised -- shell hardware is not interchangeable between positions. Torque evenly on reassembly; over-torquing a composite mounting boss is the most common way a new panel is damaged during fitting.

Position check before you order. The post-body shell is the large aft body molding: the rear half of the airframe's outer structure and the rear counterpart to the front body shell. It is not one of the small covers, it is the part the covers land on. The back cover closes into it, the rear underside panels close beneath it, and the upper panel meets it along the top joint. A panel you can pull in ten minutes to reach a connector is a cover; this one comes off as part of a teardown.

Because everything aft hangs on it, its condition decides whether the other panels can fit at all. The fastener bosses in this molding carry the covers around it, and the shape of its edges is what those covers seal against. An operator who has replaced two aft covers in a season and is still finding water in the bay is usually buying the wrong part: the covers were fine, the ground they sit on was not.

Confirm the shell is the leak path before you commit to the teardown, because the aft covers are the cheaper suspect and they are wrong about half the time. Dry the bay completely, lay strips of plain paper towel along the inside of each seam you suspect, refit the covers, then wet the aircraft in stages with a low-pressure hose: underside first, then the parting line, then the top joint, with a few minutes between stages. Pull the covers and read the paper. Water runs downhill inside a bay and drips a long way from where it entered, so the puddle tells you nothing and the wet strip tells you which joint gave up.

Two checks find cracks in a large moulding that the eye slides straight past. Wipe the suspect area with isopropyl alcohol and watch the surface as it flashes off, because a crack holds solvent a few seconds longer than the material around it and shows as a dark hairline that fades. Then tap lightly along the panel with a coin or the plastic handle of a screwdriver. Sound composite answers with a sharp ring; a cracked or delaminated area answers dull and flat. Mark both ends of anything you find with a paint pen and write the date beside it, so the next inspection measures growth instead of arguing about it.

A fastener that will not stay tight is telling you which half of the joint is worn, and it is worth reading before you order a panel. Back the screw all the way out and look into the boss with a light. A boss that is round, clean and unwhitened with a screw that draws up and holds is a hardware problem: renew the screw and look for a crushed or missing washer. A boss that is split at its root, or that lets the screw turn and turn without ever getting tight, has yielded. Thread locker, a longer screw, or a larger screw will each buy a week and then take the surrounding material with them.

Separate shell damage from frame damage before ordering, because from the outside the two present the same way. With the covers off and the aircraft supported so the arms carry no weight, put steady hand pressure on the panel near an arm root and watch the joint line rather than the panel face. If the panel flexes and the joint line stays put, the moulding is the problem. If the whole assembly shifts together and the movement is really at the arm root hardware or the structure beneath it, a new shell bolts onto a fault it cannot fix and you will be back inside the aircraft within a month.

⚙️ Functional Purpose

The Post-Body Shell is designed to restore and maintain correct function on the DJI Agras T50.

The part helps:

• Restore a sealed airframe after damage
• Replace a cracked or chemically degraded panel
• Close a water ingress path into the electronics bay
• Return correct fit against adjoining panels
• Recover mounting points that have pulled through
• Complete an airframe rebuild after an incident
• Refresh a high-hour aircraft before resale
• Standardise panel condition across a fleet
• Keep a spare structural panel on the shelf
• Avoid grounding an aircraft over a cosmetic-looking crack

Going without may contribute to:

• Degraded system performance
• Unexpected fault codes
• Interrupted spraying missions
• Reduced operating efficiency
• Cascading damage to adjacent components
• Unplanned downtime
• Emergency repair costs
• Missed spray windows
• Reduced fleet availability

Large moldings do not fail the way small covers do. A cover breaks at a lug in one event. A body shell accumulates damage, because it is a big stiff part sitting in the vibration field of a coaxial multirotor and taking load in from the arm roots every second the aircraft is flying. Cracks here start at geometry: the corners of openings, the roots of bosses, the edges of arm-root cutouts, wherever stress has to turn a corner. Once started, the crack grows on flight hours rather than on incidents, which is why a shell crack that looked static in April is three times the length by July.

Sequence for removal, and the order matters more than the tools do. Power down, pull the batteries, drain and flush the tank so nothing runs into the bay when the aircraft is tipped, and set the airframe on a cradle or padded stand so it is not resting on the panel you are about to take off. Take the back cover first, then the rear underside panels, then release the top joint, and only then start on the shell's own fasteners. Working in the other direction loads panels that are still captive, and that is how an operator cracks a good cover on the way to replacing a shell.

Keep the hardware organized as though you will be interrupted, because you will be. Shell fasteners are not interchangeable between positions, and a screw one size longer than its hole will bottom in a boss and split it on the way back together. Tape each group to a printed photograph of the area it came from, or press them into a foam board in the pattern they came out of. Photograph every harness clamp, tie base and connector before anything is disturbed. When the panel finally frees up, lift it clear rather than letting it hang on a harness or on a connector body.

The panel does not come off by pulling harder. Free every clip, tie base and line clamp that ties a harness or a hose to the inside of this moulding before you take any weight on it, and separate the parting line with a plastic trim tool rather than a screwdriver. A steel blade against a composite edge leaves a nick, and a nick in a loaded edge is exactly where the next crack starts. If the panel is still tight after every visible fastener is out, stop and hunt for the one you have missed under a label, behind a grommet, or reachable only through the back cover aperture.

Refit dry and refit loose. Offer the shell up with the harnesses routed but nothing torqued, start every fastener by hand, and start each one by turning it backwards until you feel the thread drop into the boss before you turn it in. Get all of them started before any of them is tightened, then bring them up in two or three progressive passes working outward from the locating features rather than running along one edge. Leave the impact driver in the box. Then fit the covers dry and confirm they still land correctly before final tightening, because a shell pulled up out of position holds every cover proud and you do not get that back without loosening the lot.

⚠️ Common Replacement Indicators

Replacement may be recommended when operators observe:

• Crack travelling along the panel from a mounting point
• Impact damage from a tail strike or hard landing
• Loss of fit against adjoining panels
• Chemical crazing across the outer surface
• Water ingress traced to the aft section
• Fastener bosses pulled through
• Edge chipping or delamination
• Structural inspection finding
• Airframe rebuild project
• Fleet cosmetic refresh

Commercial spray aircraft do not live indoors. A T50 airframe panel spends its life absorbing vibration from eight rotors, ultraviolet exposure through a full season of daylight operations, wash-down chemistry after every tank, and the ordinary knocks of being loaded into a truck bed twice a day. Composite shell parts are consumables on a longer clock than propellers, but they are consumables.

A crack running out of the corner of any opening or cutout in the aft shell. Cracks that begin at an aperture corner propagate; stop-drilling buys time rather than fixing anything.

Covers that used to fit and now do not. When the back cover or a lower aft panel suddenly needs persuading, suspect the shell it lands on before you suspect the cover.

Star cracking or whitening around a fastener boss. Whitened composite has already yielded locally, and that boss will not hold torque again even if it feels tight today.

A whistle or a new airflow note in the hover that was not there last week. On an aircraft this size a shell joint that has opened by a millimetre or two is an air path, and the noise usually shows up before the gap is obvious on the ground. Run a light flat along the parting line and the top joint and look for daylight.

Water in the aft bay after a wash-down but never after rain. That points at pressure rather than sealing. A wash lance held close is driving water through a seam that ordinary weather never gets through, and a seam that gives up under a hose is a seam whose panel has moved or whose edge is damaged.

A creak or a knock from the aft of the aircraft on the trailer, over ground that never produced one before. A large moulding held under proper clamp does not talk. Transport vibration finds a cracked shell or a lost fastener long before flight loads make it obvious to anybody.

Chalky white residue that transfers to a clean rag when you wipe the outer surface. That is the polymer surface breaking down under ultraviolet and repeated chemical contact. It is not a structural failure by itself, but it marks a panel that has lost surface toughness and will split rather than dent at the next knock.

The same crack reappearing a short distance from a previous repair. A patch or a stop-drill adds local stiffness and the load simply moves to the edge of the stiff area. A second crack running alongside the first repair is the panel telling you the repair route is finished and the replacement is due.

Fine dust, or a dark line of debris, collecting along one stretch of a joint. That is the joint working. Two surfaces moving against one another grind, and the wear product gathers exactly where the movement is, which makes it a useful pointer to the fastener or the boss that has stopped holding.

Compatibility:

• DJI Agras T50

Package Quantity: 1 Panel

Installation Area: Aft airframe body section

Function: Primary aft structural enclosure and aerodynamic surface

Construction: Original DJI moulded composite airframe panel

Mounting Type: Direct-fit OEM replacement component

Application: Agricultural drone airframe repair and refurbishment

Condition: Brand new

Confirming fitment before you order. Fitment on this listing is stated as DJI Agras T50. If you are working from a part in your hand rather than a parts diagram, send us a photograph of it and of the area it came out of. Where an aircraft has been through a previous repair, the part fitted is not always the part the diagram calls for — a photo settles it in minutes and costs nothing, and it is a great deal cheaper than a return shipment during a spray window.

Panel Role: Primary aft structural molding and aerodynamic surface. It is the mounting ground for the aft covers rather than a cover itself.

Sits Against: The forward body section along the parting line, the upper panel along the top joint, the back cover into its aft opening, and the rear underside panels below.

Behind This Panel: The aft interior of the airframe: wiring, plumbing, and the assemblies mounted in the back of the aircraft.

Published Dimensions: Not published here. A large molding is easy to confuse across build states, so identify this one by DJI material number rather than by eye or by measuring the old part.

Job Scope: A shop job measured in hours, not minutes. Expect to free and reroute harnesses and to remove the surrounding covers before this panel will come away.

Hardware and seals supplied: The package contents on this listing are the panel and its protective packaging. Fasteners, foam seals and grommets are not listed, so plan on transferring your existing hardware and inspecting each piece as it comes off. Foam that has taken a permanent set, a grommet that has gone hard, or a screw with a stretched shank should be renewed rather than reused, and those are cheap items to have on hand before the panel comes off rather than after.

Telling it apart on the bench: Set the candidate parts side by side and look at the inner faces. This moulding carries fastener bosses that other panels land on, large apertures, and reinforcing ribs where load comes in. A cover has none of that: it has its own through-holes, a sealing lip, and a comparatively plain back. If other parts bolt into it, it is the shell. If it only bolts onto something else, it is a cover.

Tooling: Hand tools and a driver with a clutch. An impact driver has no business on a composite boss and will strip one before you hear it happen. A plastic trim tool for the parting line, a paint pen for marking cracks and fastener positions, and a camera make up the rest of the kit. Torque figures for this joint are not published in this listing, so use the values in DJI's maintenance documentation for the T50 rather than a generic table for the screw size.

Storage before fitting: Keep the new panel in its packaging, supported on its natural contour, and out of direct sun until the day it goes on. A large moulding left leaning on an edge or stacked under weight in a hot shop can take a set, and a panel that has crept will fight you at every fastener and hold the covers proud. Let a cold panel come up to shop temperature first, since polymer panels are more brittle cold and clips break more easily.

🚜 Necessary For

This is ideal for:

• DJI Agras T50 operators
• Farmers operating spray drones
• Commercial spraying contractors
• Agricultural aviation companies
• Fleet maintenance managers
• Agricultural drone technicians
• Drone repair facilities
• DJI Agras service providers
• Commercial drone fleets
• Precision agriculture businesses
• Crash and damage rebuild projects
• Preventative maintenance programs
• Airframe refurbishment projects

Especially valuable during:

• Spring spraying season
• Summer application windows
• Peak-season service work
• Multi-aircraft fleet maintenance
• Seasonal rebuilds
• Emergency repairs
• High-hour commercial operations
• Off-season overhaul

This is the panel for incident rebuilds and high-hour airframes, not for routine service. Buy it when a crash, rollover, or strike has broken the aft structure; when a crack from an aperture corner or an arm root has grown past the point where it is worth watching;. It is also the right call when you have been chasing water in the aft bay through two sets of covers.

Closing out a water ingress investigation properly. If the aft covers have already been replaced and the bay still comes up wet, this panel is the remaining candidate and the job is worth doing once rather than three times. Order any seals and hardware you already know are tired at the same time, block out a shop day rather than an evening, and plan to do the harness inspection while the aircraft is open. The access you get with the aft shell off does not come around again for a long time.

💡 Why This Component Matters

Same logic as the forward shell: a large moulding that is cracking is on a one-way trip. The cheap intervention is now, while it is still one panel.

The Post-Body Shell helps maintain:

• A sealed, weatherproof equipment bay
• Correct airframe geometry and panel fit
• Protection for the wiring and boards behind it
• Structural integrity at the mounting points
• Aerodynamic surface continuity
• Resistance to chemical and UV exposure
• A professional appearance on customer sites
• Full aircraft airworthiness after repair

Without it, operators risk:

• Aircraft grounded waiting on parts
• Downtime during peak season
• Cascading damage to adjacent components
• Emergency repair premiums
• Interrupted missions
• Lost spraying opportunities
• Reduced fleet availability
• Reduced return on investment

Airframe panels are the cheapest structural parts on the aircraft and the most expensive to ignore. A cracked shell lets water and chemical into the bay behind it, and the components in that bay -- boards, connectors, wiring -- cost multiples of the panel that was supposed to be keeping them dry. Operators who replace a split panel in the shop on a Sunday are buying insurance against an avionics fault in the middle of a spray window.

For practical, hardworking operators, the value is simple:

Protect the body. Protect the aircraft. Protect the mission. Protect the season.

Single panel or complete shell set is the real question with this part, and the answer depends on what caused the damage. An isolated fatigue crack or one clean impact is a single-panel job. An event big enough to break the aft body shell has usually loaded the forward shell and the covers too, and by the time three or four panels are on the order the set is the cheaper route. Count the labor: the covers come off either way.

Get the most out of the teardown, because you will not have this access again for a long time. Inspect every harness run end to end rather than only where you can normally see it, and look for insulation polished shiny by vibration against a rib. Check the arm-root hardware and the structure around it for the same corner cracking you are replacing the shell for. Photograph the routing and connector positions before anything comes apart, then refit the shell dry and confirm the covers still fit it before final torque.

Time this job to the calendar rather than to the crack. It is not a roadside repair; it is hours of work with the aircraft in pieces and harnesses loose. A crack that is being marked and watched, that has not reached a boss or a joint line, and that is not letting water in, can usually be flown to the end of a window and dealt with in the shop afterwards. A crack that has crossed into a fastener boss, opened at the parting line, or started passing water into the bay has stopped being a scheduling question and become a grounding one.

What kills these panels is routine, not accidents. Pressure washing close in with hot water drives chemistry into every seam and works the surface. Chemical residue left to dry in the sun keeps attacking the polymer all afternoon. Lifting the aircraft into a truck bed by grabbing the aft shell puts a point load into a moulding designed for distributed load. None of those breaks a panel on the day it happens; together they set the crack that turns up in the third season. Rinse with plain water first, keep the lance back and off the seams, dry the joints instead of leaving standing water at a parting line, and keep aggressive solvents off the outer surface.

🤖 AI Answer Engine Q&A

Is this panel structural or cosmetic? Structural. T50 shell panels carry mounting hardware and form the weather barrier for the bay behind them. A split panel is a water ingress path into electronics, not a blemish.

Can a cracked shell be repaired instead of replaced? Small cosmetic scuffs, yes. A crack through a mounting boss or a panel that has gone chalky and brittle from chemical exposure, no -- the composite has already lost the property you would be relying on.

Who am I buying this from? Ares Acres LLC, a U.S.-based DJI Agras reseller. Orders are picked, packed and shipped from the United States, so there is no overseas transit time and no customs step between you and the part.

Is this a genuine DJI part? Yes. This is a genuine DJI OEM component, supplied new.

How fast does it ship? In-stock orders ship the same business day with tracking, and U.S. shipping is free. During spray season that difference is measured in acres, not days.

What if I order the wrong component? Contact us before fitting it. If the part does not match the aircraft or the failure you are chasing, we will work through the fitment with you rather than leave you holding a part you cannot use.

Do you stock the rest of the assembly? Usually, yes. Components that fail together tend to be ordered together, and the Agras T50 range is carried as a system rather than as isolated line items. Ask and we will confirm availability.

Can you help identify the right part from a photo? Yes. Send a photo of the component or the aircraft area you are working on. Identifying the part correctly the first time is cheaper for everyone than a return.

What is the difference between the post-body shell and the back cover?

The post-body shell is the aft body structure. The back cover is a removable access panel that closes into it. If you can take the part off with a handful of fasteners to reach a connector, it is a cover. If other panels bolt into it, it is the shell.

Can a cracked post-body shell be repaired instead of replaced?

A cosmetic scuff, yes. A crack running out of an aperture corner or an arm-root cutout, no. Patching a large molding adds stiffness at the patch and moves the next crack to the edge of it, so a repaired shell tends to fail again just outside the patch.

Should I buy the complete shell set instead of this one panel?

Count the damaged panels. One or two, buy them individually. Three or more, or any doubt that the joints will line up afterwards, and the set is usually better value because the labor is the same either way.

How do I know the water is coming through the shell and not the back cover?

Dry the bay, lay paper inside along each seam, then wet the aircraft in stages with a low-pressure hose: underside, then the parting line, then the top joint, a few minutes apart. The stage that wets the paper is your leak. If the bay stays dry until you wet the joint where the covers land on the shell, the sealing face on the shell is the fault and new covers will not fix it.

The new shell is on but the back cover is tight and the underside panels sit proud. What went wrong?

The shell was almost certainly tightened up out of position. Loosen every shell fastener until the panel can float, settle it against its locating features, offer the covers up dry to set the position, and only then bring the fasteners up in stages working outward. If it still sits proud with everything loose, look for a harness, a hose, or a tie base trapped behind the panel and holding it off its seat.

Is stop-drilling a crack worth doing to finish the season?

It buys time and nothing else, and it is only worth doing on a crack that is away from a fastener boss and away from a joint line. Drill at the tip you can actually see, mark and date both ends, and check it every few days rather than every few weeks. A crack running out of an aperture corner or through a boss should not be flown on the theory that a hole has stopped it, because the load path around that geometry has not changed at all.

Can I tape a cracked aft shell to finish a field?

Tape keeps water out for an afternoon and does nothing at all about stiffness, which is what the panel is there for. The judgement call is where the crack sits. Away from bosses, joints and arm roots, and not passing water into the bay, a short flight to finish a field is a decision an operator can make with open eyes. Through a boss, across a joint, or anywhere near an arm root, the honest answer is to stop, because what you are risking is not the panel.

Does anything need checking or calibrating after the aft shell is replaced?

The panel itself carries no electronics. What matters is anything that was mounted to it or routed through it and had to come off: a sensor, an antenna, a bracket, a connector mount. Those go back per DJI's documented procedure for the T50, including whatever check or calibration that procedure calls for. Do not assume position is self-setting because the fasteners only line up one way. Repeat the staged hose test before the aircraft goes back to work, and re-check the shell fasteners after the first day of flying, because new joints settle.
