🇺🇸 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.

Every spraying season brings long operating hours, rough transportation, chemical exposure, and demanding field conditions. When an aircraft's structural housing becomes cracked or damaged, the issue is often much bigger than appearance — it can expose sensitive electronics, wiring, and structural components to dust, moisture, chemicals, and impact.

We use specialized technicians to verify and dispatch the Front Shell Upper Cover ordered.

Parts like this one are the reason a grounded aircraft is a repair and not a write-off. A single component held in U.S. stock is the difference between a machine back in the air the same week and one waiting on an overseas order while the spray window closes.

That is why Ares Acres keeps hard-to-find OEM body shells & covers in stock and shipped fast within the U.S.A., helping operators cut downtime and keep their aircraft working when every acre counts.

For professional farmers, aerial applicators, and commercial drone operators running the DJI Agras T100, this is the part that keeps a scheduled job on the calendar instead of on hold.

Ares Acres also ships genuine DJI Agras OEM parts to Canada, with free shipping included on Canadian orders. Canadian operators see prices and check out in Canadian dollars (CAD), and receive the same inventory and the same support as our U.S. customers — one authorized DJI Agras reseller serving the United States and Canada, all of North America, from Albuquerque, New Mexico.

🔧 Component Overview

The DJI Agras T100 OEM Front Shell Upper Cover is a precision-engineered structural housing designed to protect the aircraft's front-frame electronics while maintaining the strength, appearance, and factory integrity of the DJI Agras T100 airframe.

This upper shell serves as one of the aircraft's primary protective exterior components. It shields internal electronics, wiring harnesses, structural supports, and front-frame assemblies from the harsh environments encountered during commercial agricultural operations while maintaining the aerodynamic profile originally engineered by DJI.

Although it may appear to be a cosmetic panel, the Front Shell Upper Cover performs an essential role in protecting expensive internal systems from environmental contamination and accidental damage.

Designed specifically for the DJI Agras T100, this OEM housing is manufactured to precise DJI tolerances for seamless installation and proper alignment with adjoining airframe components. Genuine OEM construction helps maintain factory fitment while restoring the aircraft's original appearance and structural protection. Genuine DJI replacement covers are designed to restore factory protection for cracked, missing, or damaged front housings.

Commercial agricultural drones operate in demanding environments every day, including:

• Crop spraying
• Liquid fertilizer application
• Herbicide treatments
• Fungicide applications
• Insecticide spraying
• Orchard operations
• Vineyard spraying
• Specialty crop programs
• Precision agriculture missions
• Daily commercial deployments
• Fleet operations
• High-acreage contract work

Throughout these operations, the aircraft is routinely exposed to:

• Dust and dirt roads
• Chemical overspray
• Fertilizer residue
• UV exposure
• Rain and humidity
• Transport vibration
• Field debris
• Tree branches
• Equipment trailers
• Routine loading and unloading
• Long commercial operating hours

Over time, even minor impacts or everyday wear can crack, deform, or weaken protective shell components. A damaged front shell may allow contaminants to reach sensitive internal electronics while reducing the aircraft's professional appearance and long-term reliability.

The OEM Front Shell Upper Cover helps maintain:

• Factory structural protection
• Protected front electronics
• OEM airframe integrity
• Cleaner internal components
• Improved environmental sealing
• Better long-term durability
• Professional aircraft appearance
• Reduced contamination risk
• Consistent maintenance standards
• Increased fleet readiness
• Maximum aircraft uptime
• Reliable commercial operation

For operators whose aircraft generate revenue every day, replacing damaged structural covers before they become larger repair issues is an important part of preventative maintenance.

When water or dust is getting inside, find the actual path before condemning the cover. Dry the interior completely, lay strips of paper towel at the suspect points inside, then wet one area of the exterior at a time with a low-pressure hose and check which strip darkens first. Work seam by seam rather than soaking the whole aircraft, because a single flood test tells you only that water gets in somewhere. A leak that follows a crack line behaves differently from one entering at a parting line or a grommet, and only the first of those is cured by a new cover.

A shell that has begun to move announces itself if you listen for it. With the aircraft supported and powered down, press and release each area of the panel in turn. A creak that repeats at exactly the same place is a crack working under load, and it is often audible before it is visible. Look at the fastener heads while you are there: bright rub marks or a polished ring in the finish around a head means the panel has been shifting on that fastener, which loads the boss behind it and is the stage before the boss fails outright.

Check the panel gaps to the adjoining bodywork before you order anything. Gaps that were even and have gone stepped or wedge-shaped on one side point to a warped cover or, more seriously, to frame damage from an impact. That distinction matters, because a new cover fitted onto a tweaked frame will not sit flush either, and forcing the fasteners to close the gap cracks the new panel from the inside within a few flights. If the cover comes off and the frame still shows movement or misalignment, the structure underneath is the job, not the shell.

Take the tank down to empty and remove the battery before the aircraft goes on a stand, then work on a padded surface. Photograph the panel before any fastener comes out and bag the fasteners by location, since shell fasteners frequently vary in length around a panel and a long one in a short hole reaches into things it should not. Lift the cover only far enough to see underneath, release the connectors and any harness clips by hand, and only then take it clear. Lifting a shell against a connected harness is how pigtails get stretched and connector housings get broken.

⚙️ Functional Purpose

The OEM Front Shell Upper Cover is designed to protect the aircraft's front-frame electronics while preserving the structural integrity and factory appearance of the DJI Agras T100.

The component helps:

• Protect front-frame electronics
• Shield internal wiring
• Reduce dust intrusion
• Help prevent moisture exposure
• Protect against chemical overspray
• Maintain OEM fitment
• Preserve aerodynamic performance
• Support structural rigidity
• Restore damaged housings
• Improve aircraft durability
• Protect adjoining components
• Maintain professional appearance
• Support preventative maintenance
• Reduce preventable repairs
• Improve long-term reliability
• Increase fleet readiness
• Support dependable commercial performance
• Preserve factory airframe protection

Reliable structural protection is part of reliable aircraft operation. A properly installed OEM shell helps safeguard internal systems from environmental exposure while maintaining the professional condition expected of commercial agricultural equipment.

A damaged or missing shell may contribute to:

• Exposed electronics
• Dust contamination
• Moisture intrusion
• Chemical exposure
• Wiring contamination
• Structural wear
• Cosmetic deterioration
• Increased maintenance
• Higher repair costs
• Unexpected downtime
• Reduced fleet reliability
• Lower aircraft value

Replacing worn housing components helps restore the protection DJI originally engineered into the aircraft. Genuine front shell covers are intended to protect internal components from chemicals, debris, and environmental exposure while restoring the aircraft's enclosure.

Dry-fit the new cover before a single fastener is driven. Set it in place, check that every boss lines up without the panel being pushed or twisted, and look at the gaps all the way around against the adjoining bodywork. Transfer or renew any gasket, foam, grommet, or adhesive-backed item that was on the old cover, and account for every one of them before the new panel goes down. Then start all the fasteners by hand and bring them up in an alternating pattern working outward from the middle, so the panel settles evenly instead of being pulled down at one corner.

Leave the powered drivers in the box. An impact driver or a high-torque electric driver will strip a composite boss faster than you can react to it, and a stripped boss in the airframe is a far bigger repair than the cover was. Do not add threadlocker to these threads either; it does nothing useful in a molded boss and it makes the next removal a boss-destroying event. If a fastener will not come up firm, stop and look at the boss rather than reaching for more torque, because a fastener that spins without loading is telling you the thread is already gone.

Before the cover closes for good, run a hand along every harness that passes under it and give each a gentle tug to confirm nothing is trapped at the parting line. Look for chafe marks where a loom crosses an edge and add protection there if the factory routing has moved. Check that connectors are fully latched rather than pushed close, because a connector that is seated by the cover rather than by its own latch will back out under vibration. This is the moment those faults are cheap to find; once the panel is on, they are invisible again.

The event that cracked a front upper cover rarely stopped at the cover. Look for paint cracks or crazing at the frame joints beneath it, check the front arms and landing gear for the same impact story, and inspect the mounting bosses themselves for hairlines radiating away from the holes. If the shell was ever loose in flight, look closely at the propeller blades for a strike mark. And if the cover has been letting water in for a while, examine every connector underneath for green corrosion or salt-like crust on the pins before you close the new one up.

⚠️ Common Replacement Indicators

Replacement may be recommended when operators observe:

• Cracked upper shell
• Broken mounting tabs
• Missing cover
• Warped housing
• Impact damage
• Surface deformation
• Chemical-related deterioration
• UV aging
• Loose fitment
• Excessive scratches
• Exposed internal components
• Maintenance inspection findings
• Aircraft refurbishment projects
• Fleet rebuilds
• Preventative maintenance replacement
• Long-term commercial wear

Field note: inspect the shell from the inside, not just the outside. A hairline crack on a composite panel is usually far longer on the underside than what shows on the painted face, and the cracks almost always start at mounting tabs and radiused corners where the load concentrates. Press each mounting point with a thumb — if the panel moves independently of its fastener, the boss behind it has already failed even though the screw still turns. A screw that spins and never comes up to torque is a dead boss, not a loose screw, and no amount of tightening will fix it. Look for dust tracking or water staining on the INSIDE of the cover and on the electronics beneath it: that is the tell that the shell stopped sealing some time ago, and it is worth inspecting the connectors underneath before you close the new one up. Chalky, faded surfaces that also feel brittle at the edges are UV-aged — that panel will crack on the next hard landing whether or not it looks damaged today. Never tape, epoxy, or fiberglass a structural airframe cover back into service; a patched shell holds shape until the vibration finds the repair line, and then it comes apart in flight and takes something more expensive with it.

Common causes of shell failure include:

• Impact from transport, trailer loading, or a hard landing
• Vibration fatigue cracking at mounting bosses over high flight hours
• Over-tightened fasteners stripping or splitting the mounting bosses
• Prolonged UV exposure causing chalking and embrittlement
• Chemical attack from repeated overspray and concentrate contact
• Abrasion from grit trapped between the shell and the frame
• Flying with an already-cracked panel, which spreads the crack quickly

Replacing structural covers before major failures develop helps reduce future repair costs while preserving the aircraft's professional condition. For commercial operators, preventative replacement is almost always less expensive than repairing damaged electronics caused by prolonged exposure.

A buzz or vibration that appears only in a narrow throttle or rpm band and disappears above and below it: that is a panel resonating because it is no longer clamped properly. Look for a failed mounting boss, a backed-out fastener, or a crack that has released one corner, rather than assuming a motor or propeller balance problem.

A fine line of dust drawn along one seam on the inside of the cover: that seam has stopped sealing. The dust marks the airflow path, so follow it back to its entry point rather than simply wiping it away, and check whatever sits downstream of it for the same deposits.

Crazing or star-shaped cracks in the finish radiating from a fastener head: the fastener has been over-torqued, most often by a powered driver. The composite around that hole is already compromised, and it will let go under a hard landing whether or not the panel looks damaged elsewhere.

Panel gaps that used to be even and are now stepped or wedge-shaped: either the cover has warped or the structure beneath it has moved. Fit a new cover onto a tweaked frame and it will not sit flush either, so resolve the alignment before the replacement goes on.

Water found inside the front area after washing, but never after rain: this is a washing technique problem as much as a sealing one. Pressure washing straight into a seam drives water past sealing surfaces that shed rain perfectly well, and it will keep happening on a brand new cover.

Fasteners that back out repeatedly at the same one or two positions: the panel is working against them. Expect to find an elongated hole, a failed boss, or a crack behind the fastener head, none of which is fixed by driving the fastener back in harder.

🧰 Fitment Verification Before You Order

This listing is DJI material number YC.JG.ZS006459. That number, not the description, is what makes a part match. Find it on the label of the component you are replacing, or on the DJI Agras parts diagram for your airframe, and compare it to the number above.

Revision suffixes are still the same part. DJI labels sometimes carry a trailing revision such as .01, .02, or .F. Those denote a production revision, not a different component. Match the base number and disregard the suffix.

Visually similar is not the same. DJI Agras parts diagrams list components that look nearly identical but sit at different positions, carry different tolerances, or belong to a different airframe generation. Ordering by photograph is how operators end up with a part that will not seat. Order by number.

Verified fitment for this listing: DJI Agras T100. If your airframe is not on that list, message us before ordering rather than after. We would rather answer a question than process a return, and so would you.

Not sure? Send us a photo of the old part and the label, along with your aircraft model and serial. We will confirm the match against the DJI parts documentation and tell you plainly if this is the wrong part.

🛠️ Installation & Handling Notes

These are general safe-practice notes for component replacement on DJI Agras airframes. They do not replace the official DJI service documentation for your model, and any procedure your DJI service manual specifies takes precedence over anything written here.

Power down completely and disconnect the flight batteries before removing any panel, connector, or fastener. Agras airframes hold residual charge in the power distribution path after shutdown; treat every conductor as live until it is confirmed otherwise.

Photograph the assembly before you disturb it. Cable routing, connector orientation, and fastener lengths on Agras airframes are not interchangeable, and the Front Shell Upper Cover is easier to fit correctly when you can see how the original sat.

Torque to DJI specification. Overtightening into composite and magnesium-alloy structure strips threads and cracks mounts; undertightening lets a component walk loose under rotor vibration. Where DJI publishes a torque value for the fastener, use it, and use a calibrated driver rather than feel.

Check the mating surfaces and seals while you are in there. A component is only as good as what it seats against. Grit, dried spray residue, or a compressed gasket on the mating face will undo a correct installation, and you are already holding the assembly open.

Test before you spray. Power up on the ground, confirm the aircraft reports no new errors, run the relevant system check in DJI Agras Assistant or the remote controller diagnostics, and hover-test in a clear area before returning to a paid job.

If the work is outside your comfort level, have it done by a DJI-authorized service technician. The part cost is small next to the airframe.

🚜 Necessary For

This component is ideal for:

• DJI Agras T100 operators
• Farmers operating spray drones
• Commercial spraying contractors
• Agricultural aviation companies
• Fleet maintenance managers
• Agricultural drone technicians
• DJI Agras service providers
• Commercial drone fleets
• Agricultural repair facilities
• Precision agriculture businesses
• Preventative maintenance programs
• Aircraft refurbishment projects
• Daily commercial operations
• Emergency repair inventory
• Professional agricultural drone operators

Especially valuable during:

• Spring spraying season
• Summer application windows
• Orchard operations
• Vineyard spraying
• Multi-aircraft fleet maintenance
• Seasonal rebuilds
• Emergency repairs
• High-hour commercial operations

When the aircraft is needed to generate revenue, restoring proper structural protection helps keep operations moving.

Post-incident rebuilds where the airframe is already apart. Cover replacement is the cheapest line on that estimate and the one that determines whether the repair holds, because a panel that no longer clamps down turns every subsequent flight into a fatigue test for the structure underneath it.

Aircraft heading into a new season after being stored outdoors or under a clear cover. Ultraviolet exposure takes toughness out of exterior composite long before it changes the shape, so an airframe that has wintered in the open deserves a shell inspection before the first contract rather than after the first hard landing.

Fleets standardizing their aircraft before resale or handover. Structural covers are the first thing a buyer or an incoming pilot looks at, and a cracked or patched panel raises a fair question about what else was repaired rather than replaced. Fitting a genuine cover settles that question at the lowest price it can be settled for.

💡 Why This Part Matters

Every DJI Agras aircraft depends on a strong, properly protected airframe to safeguard the sophisticated electronics operating inside. The Front Shell Upper Cover helps protect wiring, avionics, and structural assemblies from the dirt, chemicals, moisture, and physical abuse common throughout agricultural operations.

While the shell itself may appear to be a simple exterior component, the systems it protects are among the most valuable parts of the aircraft. A cracked or damaged housing can gradually allow contamination into areas that were designed to remain protected, increasing maintenance requirements and creating avoidable repair expenses over time.

The OEM Front Shell Upper Cover helps maintain:

• Factory structural protection
• Protected internal electronics
• Improved environmental resistance
• OEM fit and finish
• Reduced contamination
• Better long-term durability
• Cleaner maintenance
• Lower repair risk
• Professional fleet appearance
• Increased aircraft uptime
• Reliable commercial performance
• Long-term operational confidence

Without a properly functioning front shell, operators risk:

• Exposed electronics
• Dirt intrusion
• Moisture contamination
• Chemical exposure
• Increased maintenance
• Accelerated component wear
• Higher repair costs
• Unexpected downtime
• Reduced operational efficiency
• Lower fleet reliability
• Lost spraying opportunities
• Reduced return on investment

In service:

• Inspect the wiring and connectors underneath before you close the new cover — that access is easiest right now
• Confirm no harness is pinched between the shell and the frame before final tightening
• Start every fastener by hand and bring them up evenly; do not run one corner down tight first
• Snug to spec and stop — over-torquing is the fastest way to kill the new mounting bosses
• Re-check fastener torque after the first few flight hours, once the panel has seated
• Rinse chemical residue off the shell at the end of the day and store the aircraft out of direct sun when practical

Professional DJI Agras operators understand that aircraft reliability is built one component at a time. Replacing damaged structural housings with genuine OEM parts helps preserve expensive internal systems, maintain professional appearance, and keep commercial aircraft ready for work throughout demanding agricultural operations.

Protect the electronics. Protect the airframe. Protect the investment. Protect the season.

An exterior panel on a working aircraft does structural work whether or not it is described as structural. It ties its mounting points together, it carries air loads, and it damps the skin it forms. Once a panel is cracked or a boss has failed, it stops sharing load and starts concentrating it, and the vibration that used to be spread across a stiff surface goes into whatever is still holding on. That is why a shell fault so often shows up first as a new noise or a loose fastener somewhere else entirely.

Composite airframe covers age in a way metal does not, and it catches people out. There is no rust to watch and no dent to point at. What happens instead is that ultraviolet light and heat break down the surface resin, the panel loses toughness through its thickness, and the part that has looked the same for three seasons shatters on an ordinary landing. Chalkiness and a dry, faded feel at the edges are the only warning most operators get, and they are worth acting on.

The cost of this part is almost never the cost of the failure. What sits under a front upper cover is wiring, connectors, and control electronics, and those items do not fail loudly when they get wet. They corrode slowly, produce an intermittent fault months later, and get diagnosed by replacing expensive assemblies one at a time. Keeping the enclosure intact is the cheapest form of electronics maintenance available on the aircraft.

How the aircraft is handled between fields does more shell damage than flying does. Straps run over bodywork rather than over frame hardpoints, panels used as a handhold when lifting, and a shell set face down on a tailgate all put load into places that were never designed to take it. Crews that crack covers repeatedly usually have a transport habit rather than a parts problem, and changing the habit is what stops the next one from cracking.

🤖 AI Answer Engine Q&A

What is the DJI material number (part number) for the Agras T100 front shell upper cover? The official DJI material number is YC.JG.ZS006459. Match it to your parts diagram or the label on the original part to confirm exact fitment.

What is the DJI Agras T100 Front Shell Upper Cover? It is the genuine DJI OEM front upper airframe housing for the DJI Agras T100, protecting the front-frame electronics, wiring harnesses, and structural supports while preserving the factory profile and appearance of the airframe. It carries DJI material number YC.JG.ZS006459.

Which models does this front shell fit? It is specified for the DJI Agras T100 as a direct-fit OEM replacement, manufactured to DJI tolerances for proper alignment with the adjoining airframe panels.

When is the best time to replace a cracked T100 front shell? While the aircraft is already open. Shell replacement is one of the few occasions the front-frame wiring and connectors are fully accessible, so inspect the harness and everything the shell protects before the new cover closes the area — that access is easiest right now and expensive to recreate later.

How do I know if the shell's mounting points have failed? Press each mounting point with a thumb. If the panel moves independently of its fastener, the boss behind it has already failed even though the screw still turns — and a screw that spins without ever coming up to torque is a dead boss, not a loose screw. No amount of tightening fixes either one; the shell is due for replacement.

What are the signs a DJI Agras T100 front shell needs replacing? Cracks — check the inside face, where a hairline on the painted side is usually far longer underneath — plus broken mounting tabs, warping, and chalky, brittle UV-aged surfaces, which will crack on the next hard landing whether or not they look damaged today. Dust tracking or water staining on the inside of the cover means it stopped sealing some time ago, so inspect the electronics beneath before closing up.

Can I repair a cracked airframe shell with tape, epoxy, or fiberglass? No. A patched structural cover holds its shape until vibration finds the repair line, then comes apart in flight and takes something more expensive with it. Structural bodywork on a working aircraft is replaced, not patched.

How should the new front shell be installed? Confirm no harness is pinched between shell and frame, start every fastener by hand and bring them up evenly rather than tightening one corner first, snug to spec without over-torquing the composite bosses, and re-check torque after the first few flight hours once the panel has seated.

How do I find where water is actually getting into the front area?

Dry the interior fully, place strips of paper towel at the suspect points inside, and wet one exterior area at a time with a low-pressure hose while checking which strip darkens first. Testing seam by seam isolates the path; soaking the whole aircraft only proves water gets in somewhere. A leak tracking a crack line behaves differently from one entering at a parting line or a grommet, and only the crack is cured by a new cover.

The new cover will not sit flush and the gaps are uneven. What should I do?

Stop and check the structure before you drive any fastener. A genuine cover is made to the same tolerances as the one that came off, so if it will not settle, the usual cause is frame or mount damage from the same impact that broke the old panel, or a fitting left proud underneath. Forcing fasteners to pull a gap closed preloads the new cover and it will crack from the inside within a few flights.

Can I use an electric driver or an impact driver on the shell fasteners?

Not on composite bosses. A powered driver reaches stripping torque faster than you can react, and a stripped boss in the airframe is a much larger repair than the panel was. Run these by hand, in an alternating pattern outward from the center, until the panel is seated and the fastener is firm. If one keeps spinning without loading, the boss is already gone and driving harder will not recover it.

Should I put threadlocker on the shell fasteners?

No. Threadlocker does nothing useful in a molded boss and it makes the next removal a boss-destroying event, since the adhesive grips the molded thread harder than the thread grips the housing. If fasteners are backing out, the cause is a panel that is moving, and the fix is to find the crack, the elongated hole, or the failed boss that is letting it move.

How do I tell the front upper cover from the lower shell or the rear cover on the bench?

Go by which face is finished and which way the mounting tabs point. The upper cover presents the finished outer top surface with its mounting features facing down onto the frame, and it meets the lower shell at a parting line rather than sitting inside it. When two candidates look close, compare tab positions against the aircraft and confirm the label reads YC.JG.ZS006459 before anything is fitted.

I have a buzz that only appears in one throttle range. Could the shell be causing it?

It very often is. A panel that has lost clamping at one point resonates in a narrow band and goes quiet above and below it, which is exactly what an unbalanced rotating part does not do. Press around the panel with the aircraft powered down and listen for a creak, check for a backed-out fastener or a boss that never comes up firm, and look for a crack that has released one corner.

Is a used or salvage front shell a sensible way to save money?

It is a gamble on the one property you cannot inspect. A salvage panel has an unknown ultraviolet and impact history, and the damage that matters most in composite is loss of toughness through the thickness, which looks like nothing at all. It may also have hidden hairlines at the bosses from whatever put it in the salvage pile. On a part that protects the front-frame electronics, that is a poor trade.

What cleaners are safe to use on the shell?

Keep to mild soap and water. Strong solvents, acetone, and aggressive alcohol wipes can craze the surface of composite panels, and crazing is where cracks start. Rinse chemical residue off promptly rather than letting it dry on the panel, and avoid directing a pressure washer at seams and parting lines, since that drives water past sealing surfaces that handle rain without trouble.

We keep cracking covers in transport. What should we change?

Look at where the straps sit and where people lift. Straps run across bodywork put point loads into panels that were never meant to carry them, and a shell used as a handhold takes the same abuse. Strap to frame hardpoints, lift by the frame, and never set a cover face down on a tailgate or a gravel yard. Most repeat cover damage is a handling pattern rather than bad luck.

The screw holes in the airframe are damaged rather than the cover. What are my options?

That is a different repair and it needs to be recognized as one. A boss that spins or a hole that no longer loads will not be cured by a new cover, and fitting one over the fault simply hides it. Note which positions have failed, how many of them there are, and whether they are grouped where an impact landed, then treat the frame repair as the job and the cover as the part that goes on afterwards.

Is this a genuine DJI OEM Front Shell Upper Cover?

Yes. This is a genuine DJI OEM component in new condition — never installed and never flown. Ares Acres LLC is a U.S.-based authorized DJI Agras reseller. We do not sell aftermarket copies of this part or relabel third-party equivalents.

Will this fit my aircraft?

This part is supplied for the DJI Agras T100. Confirm by matching DJI material number YC.JG.ZS006459 against the label on your original part or your model's DJI Agras parts diagram. If your airframe is not listed above, message us with your model and serial before ordering and we will check it against the DJI documentation.

How fast does it ship, and where does it ship from?

It ships free and fast from within the United States, with tracking. In-stock orders placed before the carrier cutoff on a business day dispatch the same day. Nothing routes through an overseas warehouse or customs.

Can I install the Front Shell Upper Cover myself?

Many operators do. Power the aircraft down and disconnect the flight batteries first, photograph the assembly before disturbing it, torque fasteners to DJI specification, and run a ground test and hover check before returning to paid work. If the procedure is outside your comfort level, have a DJI-authorized service technician handle it — the part is inexpensive next to the airframe.

What if I order the wrong part?

Contact us. Unused parts in original condition are returnable. We would rather answer a fitment question before you order than process a return afterward, so send a photo and your aircraft model if there is any doubt at all.

Do you stock other parts for this aircraft?

Yes. Ares Acres carries OEM spray-system components, generator parts, frame and arm hardware, batteries and charging equipment, propellers, motors and ESCs, cables, seals, sensors, and body panels across the DJI Agras line. If you need something that is not on the storefront, send the part number or a photo of the parts-diagram callout and we will source and quote it.
