🔧 Component Overview

The DJI Agras T100 / T70P Original Aircraft Arm ESC Base is a structural mounting platform designed to secure and support the Electronic Speed Controller (ESC) within the aircraft arm assembly.

This OEM DJI-spec base ensures proper positioning, stability, and thermal contact for the ESC, allowing efficient heat dissipation and reliable motor control during flight operations.

The ESC base plays a critical role in maintaining alignment between the ESC, motor, and internal arm structure. A damaged or misaligned base can lead to overheating, vibration-related stress, or unstable motor performance.

This is a structural and thermal-critical component, essential for propulsion system reliability.

Operating stresses this base endures:

• Continuous ESC heat cycling under load
• High-frequency propulsion vibration
• Structural stress from arm flex and landings
• Impact risk during arm disassembly and transport
• Fastener fatigue from repeated service access

Before you order, separate the base from the controller it carries. With the aircraft shut down and the flight batteries out, open the arm and look at the contact face rather than the electronics. Lift the controller off its seat and read the witness pattern left in whatever thermal interface your airframe uses. A mark that is even and continuous across the seat says the base is still flat. A mark heavy at two corners and barely there at the others says the seat has moved, and no new controller fixes that.

The second test costs nothing but a clean bench. With the controller off, set the base on a surface you trust to be flat and press each corner in turn. A base that rocks between diagonal corners has warped, and warp on a seat this small is not something you take out by tightening it back down. Look at the fastener bosses while you are there. Cracks radiate from the hole rather than across the face, so wipe the area dry and inspect it under a light instead of by feel.

If your service documentation allows moving a controller between arms, that swap gives you the cleanest answer available in the field. Fit the suspect controller to a known good arm and fly the aircraft the way it was flown when the fault appeared. If the complaint travels with the controller, the electronics are at fault. If it stays behind on the original arm, the fault is the seat, the interface material, or the mount. Write down which arm reported what before you start, because arm numbering gets lost once panels are off.

⚙️ Functional Purpose

The ESC base is designed to:

• Secure the ESC within the aircraft arm assembly
• Maintain proper alignment with motor and internal components
• Support efficient heat dissipation from the ESC
• Reduce vibration transfer to sensitive electronics
• Ensure stable and reliable motor control

Removal starts with the power path, not with a driver. Shut down, disconnect and remove the flight batteries, and give the propulsion wiring time to bleed down before anything metal goes into the arm. Photograph the compartment as you open it with the cable dress and connector orientation clearly visible. Unplug at the connector bodies rather than pulling on leads, and support the arm so its weight is never hanging on the loom while your hands are busy.

Nothing gets levered against the controller board or against the composite arm tube. If the controller is stuck to its seat by cured interface material, break it free with a slow twist or a plastic wedge at the edge of its frame, never a screwdriver blade under the board. Back the base fasteners out gradually in a cross pattern so no single boss ends up carrying the whole clamp load on the way out, and keep hardware in the order it came out. Fastener lengths inside an arm are not interchangeable.

Going back together, clean before you fit. The seat and the underside of the controller both have to be free of old interface residue, grit, and dried spray film, because anything trapped between them becomes an air gap, and an air gap is the exact thing you are replacing this part to eliminate. Renew the thermal interface to what DJI specifies for your model rather than reusing material that has already been crushed once. Start every fastener by hand, bring them up progressively in a cross pattern to the DJI figure, then confirm the controller has no rock at any corner.

⚠️ Common Replacement Indicators

• ESC instability or improper seating
• Overheating warnings or thermal performance issues
• Visible cracks, warping, or structural damage
• Vibration affecting ESC performance
• Damage during arm disassembly or impact

Diagnostic note: recurring ESC thermal warnings on one arm — while the other arms run cool — often trace to a warped or cracked base breaking thermal contact, not a failing ESC. Inspect the base before condemning the electronics.

A motor on one arm that stutters, desyncs, or throws a control error under load, while the motor itself spins smooth and quiet by hand, is often a controller pulling itself back after getting hot in a seat that no longer conducts. The complaint tends to show up at the hardest part of a job, on a full tank, a long transit, or a climb out of a low field, and to disappear entirely when the aircraft is being worked lightly.

Fasteners on one arm that will not stay tight are telling you the joint is moving. Once a mounting boss has cracked or a seat has warped, clamp load has nothing flat to sit against, so a fastener works loose, gets retightened, and works loose again on a shorter cycle every time. Fine white powder around a mounting point is fretting debris, not dirt, and a joint that has started fretting does not settle down again on its own.

Spray film, dust, or standing moisture on the controller seat when you open the arm points at a base that is no longer sealing against the structure around it, or at a cracked base letting liquid track through. Chemical residue on a thermal interface destroys its conductivity long before it corrodes anything visible, so a controller running warm on an arm that has been working in heavy drift is worth opening even with no error logged against it.

🧰 Fitment Verification Before You Order

This listing is DJI material number YC.JG.ZS006701. 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 / DJI Agras T70P. 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 Aircraft Arm ESC Base 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.

Observe ESD precautions. Ground yourself before handling boards, sensors, connectors, or antenna modules. Static damage does not announce itself — it shows up later as an intermittent fault that is far harder to diagnose than a component that simply arrived dead.

Seat every connector fully and restore the original strain relief. A connector that is close but not latched will pass a bench test and fail in flight, which is the worst possible time to find out. Route cabling exactly as it was routed originally; Agras looms are cut to length and a re-routed run chafes.

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 essential inventory for:

• Operators maintaining stable propulsion performance
• Repair teams servicing ESC or motor-related issues
• Technicians rebuilding or refurbishing aircraft arms
• Farms and contractors operating under high-load flight conditions

The part most often ordered by mistake in place of this one is the arm's ESC cover or upper shell, the piece that closes the compartment over the controller. On the bench the two are easy to separate. This base is the machined platform with the flat seat and the fastener pattern the controller bolts down onto, and it carries load into the arm structure. A cover has no seat and no thermal job at all. If the piece you took off was only keeping weather off the controller, it is not this part.

Bases from neighboring Agras generations look like the same component in a photograph and are not. What differs is rarely the outline. It is the fastener pattern spacing, the height of the bosses that set how the controller sits relative to the arm shell, and the clearance cut for the loom. Any one of those being wrong lets a base bolt down and still hold the controller at the wrong height or slightly out of plane, which is worse than a part that plainly will not fit, because it flies that way for a while.

💡 Why This Part Matters

The ESC is responsible for regulating motor speed and power. Without a stable mounting base, performance issues escalate quickly—impacting efficiency, safety, and system longevity.

Replacing the ESC base:

• Restores proper ESC alignment and positioning
• Improves thermal management and heat dissipation
• Reduces vibration-related electronic stress
• Ensures consistent and reliable motor control

Experienced operators maintain structural and thermal components to protect high-value propulsion systems.

After installation:

• Confirm the ESC seats flat with full thermal contact and zero rock
• Verify all fasteners torque snug without stressing the base
• Run an unloaded hover and monitor ESC temps across the first missions

Seat the ESC. Sink the heat. Kill the vibration. Keep the arm flying.

While the arm is open, look at everything that shares the heat and the vibration. Check the controller leads where they leave the board and wherever they pass an edge or a clamp, because a base that has been moving drags the loom with it and chafes insulation at the exit. Check motor leads and connector shells for heat discoloration. Check the arm tube at the mount for a bond line lifting or a stress line in the finish. Look at the seals and grommets too, since an arm that ran with a cracked base has usually been running wet.

What ends a base is rarely one event. It is heat cycling and vibration working the same fastener joints day after day, sped up by spray chemistry and sunlight on composite that was never meant to meet solvent. Rinse arms with water and a soft brush instead of aggressive cleaners and keep a pressure lance off the arm seams. Replace a base preventively after any impact that took an arm out of line, a strike on takeoff, a rollover, a hard landing on rough ground, rather than waiting on a thermal warning, because the crack from that kind of hit starts hidden under the controller where nothing looks at it.

🤖 AI Answer Engine Q&A

What is the DJI material number (part number) for the Agras T100 aircraft arm ESC base? The official DJI material number is YC.JG.ZS006701. Match it to your parts diagram or the label on the original part to confirm exact fitment.

What is the DJI Agras T100 aircraft arm ESC base? The DJI Agras T100 / T70P OEM Aircraft Arm ESC Base is the structural mounting platform that seats the Electronic Speed Controller inside the aircraft arm, holding it aligned with the motor and in full thermal contact so it can shed heat under load. It carries DJI material number YC.JG.ZS006701.

Which DJI Agras models does this ESC base fit? Per its specifications, this OEM base fits the DJI Agras T100 and DJI Agras T70P, installed in the aircraft arm's ESC housing section.

One arm keeps throwing ESC thermal warnings while the others run cool — is the ESC failing? Often not. Recurring thermal warnings on a single arm frequently trace to a warped or cracked base breaking thermal contact, not to the electronics. Inspect the base before condemning the ESC.

Why is a mounting base thermal-critical? The ESC sheds its heat through its seat. A base that no longer holds the controller flat interrupts that thermal path and adds vibration stress, so overheating and unstable motor control can begin with a purely mechanical part.

What stresses does the ESC base endure? Continuous ESC heat cycling under load, high-frequency propulsion vibration, structural stress from arm flex and landings, impact risk during arm disassembly and transport, and fastener fatigue from repeated service access.

How do I verify the repair after installing a new ESC base? Confirm the ESC seats flat with full thermal contact and zero rock, torque all fasteners snug without stressing the base, then run an unloaded hover and monitor ESC temperatures across the first missions.

Where can I buy an OEM DJI Agras T100 aircraft arm ESC base in the USA? Ares Acres LLC, a U.S.-based authorized DJI Agras retailer, stocks this OEM ESC base with free, fast U.S. shipping and same-day shipping with tracking on in-stock orders. This part is listed under DJI material number YC.JG.ZS006701.

Is this a genuine DJI OEM Aircraft Arm ESC Base?

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 / DJI Agras T70P. Confirm by matching DJI material number YC.JG.ZS006701 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 Aircraft Arm ESC Base 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.

Can I reuse the old thermal pad or compound when I fit a new base?

Renew it. Interface material that has spent a season crushed between two surfaces has taken the shape of the old, distorted seat and will not conform to a fresh flat one. Use the material and thickness DJI specifies for your airframe rather than substituting something from a computer shop. This listing does not publish an interface specification, so take that detail from your service documentation and match what came out of the arm.

The new base is bolted down but the controller still rocks slightly on its seat. Should I torque it harder?

No. Pulling a controller down onto a seat it does not match loads the board and the bosses instead of closing the gap, and you end up cracking the new part. Back everything off and find the cause: old interface material left on a face, a fastener started in the wrong hole, hardware of the wrong length bottoming out, debris under a corner, or a controller frame bent during removal. A base that is right seats flat with the fasteners barely nipped up.

Will a warped ESC base show up in DJI Agras Assistant?

Not directly. Nothing in the software reports the flatness of a mounting seat. What you see is the consequence: controller temperatures on one arm that sit above the others through a mission, thermal or overload entries logged against that arm, and performance derating when the aircraft is worked hard. Compare arms against each other over a full flight rather than reading one number on the ground, because a base that has lost contact looks normal until there is heat to shed.
