🔧 Component Overview

The DJI Agras T100 OEM M1 & M3 Small Aircraft Arm is the OEM m1 & m3 small aircraft arm fitted to the arm-mounted propulsion hardware of the DJI Agras T100, responsible for converting battery power into thrust at every corner of the aircraft.

Converting battery power into thrust at every corner of the aircraft is the job description for the arm-mounted propulsion hardware, and this module is part of how it gets done. The T100 is a working machine — it earns its keep in fill-and-fly cycles, not hangar hours — and every component in the arm-mounted propulsion hardware is sized, shaped, and specified around that duty. On the official parts diagram it sits alongside ESC Module, Screw (M30-HC00930058-060030-5103-Y), Motor Cable Clamp.

Ignore a failing m1 & m3 small aircraft arm and the bill compounds: downtime in the middle of an application window, collateral wear on the parts around it, and jobs that slip to a competitor while the aircraft sits. Replacing it costs a part; not replacing it costs acres. That trade only runs one direction.

For professional farmers, aerial applicators, and commercial drone operators, this module is how the arm-mounted propulsion hardware stays field-ready instead of becoming the reason the aircraft sits.

This is a working part on a working aircraft.

The m1 & m3 small aircraft arm handles:

• Performing its designed role within the arm-mounted propulsion hardware every second the aircraft operates
• Interfacing with the surrounding propulsion system components exactly as the factory architecture intends
• Maintaining stable operation across the full temperature range of a working day
• Surviving the vibration environment of a heavy-lift multirotor at working power
• Reporting its status to the flight system so faults surface as errors, not surprises
• Holding calibration and performance over a full season of duty
• Sealing its electronics against spray drift, dust, and washdown exposure
• Restoring factory behavior the moment a worn unit is swapped out

The T100 works brutally hard for its living, including:

• Converting battery power into thrust at every corner of the aircraft
• Dawn-to-dusk spray campaigns during narrow application windows
• Repeated fill-fly-return cycles with minutes on the ground between loads
• Full-payload takeoffs from field edges, dozens of times per day
• Chemical exposure from fungicides, herbicides, insecticides, and foliar fertilizers
• Pressure-washer rinse-downs at the end of every spray day
• Vibration from eight propulsion motors running at working power
• Transport bouncing on trailers and truck beds between fields
• Temperature swings from cold morning starts to full-sun afternoons

What attacks this module in the field:

• Continuous vibration transmitted from the propulsion system
• Thermal cycling from cold starts to full-load afternoons
• Moisture ingress pressure from spray drift and washdowns
• Chemical-laden dust settling on housings and connectors
• Voltage transients during battery hot-swaps
• Connector fretting from repeated maintenance access
• UV exposure degrading housings over seasons
• Shock loads from firm landings on rough ground

That duty cycle is exactly what retires this module. None of these stresses is dramatic on its own — the accumulation is what does it. This is why propulsion system modules are inspection items every time the arm-mounted propulsion hardware is opened up, and why operators who run hard keep spares on the shelf.

A healthy m1 & m3 small aircraft arm delivers:

• Factory-correct fit in the arm-mounted propulsion hardware — no modification, no adaptation
• Exact OEM behavior the surrounding components were engineered around
• Restored performance you can verify on the first post-repair flight
• Sealing and protection maintained to the factory standard
• One less known-weak point flying through your application window
• Confidence that the repair is done, not patched
• A maintenance log entry with a real DJI part number behind it
• Full compatibility with the parts around it — because it is the part the diagram calls for

Stock the m1 & m3 small aircraft arm before the season does its work, and the arm-mounted propulsion hardware never becomes the reason the aircraft sits.

Before you condemn the arm, prove the fault is structural and not the motor or the ESC riding on it. With the battery out and the props off, spin the motor by hand and feel for roughness, drag or a catch once per revolution, then rock the motor by its bell and feel for shaft play. A bearing or a magnet problem gives you noise and drag with the arm itself still rigid. If the motor turns clean and the whole motor mount moves when you push on it, the fault has moved inboard to the arm.

Check geometry against the opposite arm rather than against your eye. Set the aircraft level and unfolded on a flat bench, sight along each arm from the center outward, and compare the motor mounting plane on the suspect arm with the one diagonally opposite it. You are looking for a mount that no longer sits parallel to the others, an arm that has rolled slightly about its own axis, or a tip that has dropped. Thrust from a motor that is not square costs you attitude authority the flight controller has to spend trim correcting.

Read composite the way it fails, not the way it looks. Clean the arm and go over it with a bright light held low and raked across the surface, working out from the root and around every fastener and every hole. Fine white or dark lines in the finish that follow the tube, a dull patch that sounds different when you tap it with a coin, and any area that feels soft or springy under thumb pressure compared with the same spot on another arm all say the laminate underneath has been damaged even where the outside is intact.

Separate arm damage from play in the folding joint and the mounting hardware. Fold and unfold the arm through its full travel and feel for a lock that no longer snaps home the same way as the others. Then, with it locked out, grip the motor and try to rock it fore and aft, up and down, and in twist while a second person watches the root. Movement that shows up at the hinge or under a fastener head is hardware to be inspected and retorqued. Movement that shows up as the tube itself flexing or a click somewhere along its length is the arm.

⚙️ Functional Purpose

The m1 & m3 small aircraft arm is designed to do one job in the arm-mounted propulsion hardware and do it to specification: converting battery power into thrust at every corner of the aircraft.

The module:

• Serves the arm-mounted propulsion hardware of the DJI Agras T100 exactly as the factory intends
• Supports converting battery power into thrust at every corner of the aircraft
• Maintains the tolerances and interfaces the surrounding parts depend on
• Withstands the chemical, vibration, and washdown environment of agricultural work
• Preserves the sealing and protection strategy of the platform
• Keeps failure modes visible and diagnosable instead of mysterious
• Restores factory behavior immediately upon correct installation
• Protects the more expensive components it works alongside
• Carries the exact DJI specification for its position
• Supports safe, predictable operation under full payload
• Eliminates the guesswork of near-fit substitutes
• Keeps the aircraft inside its designed maintenance program
• Holds up across a full season of professional duty

Function on the T100 is a chain: propulsion system performance depends on the arm-mounted propulsion hardware, and the arm-mounted propulsion hardware depends on every part in it holding specification. This module is one link in that chain — and chains fail at the worn link, not the average one.

That is why the platform's maintenance philosophy is inspection and renewal, not run-to-failure. The operators with the best uptime records are not the ones with the newest aircraft — they are the ones who replace parts like this when inspection says so, on their own schedule instead of the failure's.

A failing m1 & m3 small aircraft arm costs you:

• Downtime in the middle of an application window — the most expensive hours in agriculture
• Acres not covered while the aircraft waits on a part
• Collateral wear on the components around the failing one
• Diagnostic hours chasing symptoms instead of causes
• Rework when a temporary fix lets go mid-job
• Customer trust when scheduled work slips
• Higher repair bills the longer the fault runs
• Risk exposure every flight the fault remains aboard
• Resale value on an airframe with deferred maintenance

Fix it on your schedule, not the failure's.

Photograph the whole arm before a single fastener moves. The motor cable, its clamps, any arm light wiring and any liquid line that runs out to this position all have a specific route and specific clamp positions, and none of that is obvious once it is off the aircraft. Take pictures from above, below and at the root, note which way each connector is oriented, and count the clamps. Rebuilding an arm with one clamp missing puts a cable where the fold will chew it.

Disconnect power and pressure before you touch the structure. Remove the battery and give the aircraft time with everything off, take the propellers off this arm so nothing can be spun by hand into your fingers, and drain and depressurize the spray system if a liquid line runs out along this arm. Then support the motor end on a block or have somebody hold it. An arm that drops the moment the last fastener clears will bend a connector pin or crack a fitting on its way down.

Work electrical first, hardware second, structure last, and never pull a cable through by its connector. Release the connectors at their latches rather than tugging on the wire, open the cable clamps in order and leave them with the arm so you know how many there were, and only then take out the structural fasteners. If a cable passes through the arm or through the fuselage wall, tie a light line to it before you withdraw it so you can pull the new one back along exactly the same path.

Refit dry, aligned and to DJI torque, then prove it before you load the tank. Offer the new arm up square, start every fastener by hand so nothing cross-threads into composite or a threaded insert, and tighten in stages to the value DJI specifies for this joint with a calibrated driver rather than by feel. Restore every clamp to its photographed position, cycle the fold and unfold several times watching the cables for pinch or stretch, then run the aircraft up on the ground and confirm motor direction, that the position reports normally, and that vibration on that motor is back in line with the others.

⚠️ Common Replacement Indicators

• Error messages or warnings referencing this system in the app
• Intermittent operation that worsens with temperature or vibration
• Function loss in the system this module serves
• Visible corrosion, moisture, or chemical residue at connectors
• Physical damage to the housing after an impact
• Erratic readings or behavior the aircraft cannot self-clear
• Failures that appear under load but pass on the bench
• Burnt smell or discoloration at the module
• Repeated faults after connector reseating
• Function dropouts during arm fold or unfold
• Behavior that started after a hard landing or transport
• Age and hours — electronics in this environment are not lifetime parts

What kills propulsion system modules: the compounding of ordinary duty. Chemical exposure attacks materials, vibration works at every interface, UV ages every exposed surface, and washdowns drive water at every seam — repeated across hundreds of cycles per season. Add the occasional hard landing or transport knock and the result is predictable: the part that was fine in spring is the failure point by late season.

Replacement and verification: Replacement is a standard shop task on the T100: open access to the arm-mounted propulsion hardware, document connections and hardware positions, swap the m1 & m3 small aircraft arm for the OEM unit, and reassemble with attention to seating, routing, and torque. Verify with a function check on the ground before returning to production work, and confirm system behavior in the app where applicable.

Confirm before you order: this is DJI part BC.AG.SS001100. Check the label on your old m1 & m3 small aircraft arm or the position in your official parts diagram and match the number — revision suffixes like .01 or .F on a label are the same part.

A vibration warning that only shows up above a certain power setting, or only with a full tank, points at stiffness that has gone out of the arm rather than at balance. Damaged laminate softens before it separates, and a softer arm resonates at a lower frequency and a higher amplitude than its neighbors. If rebalancing props and swapping the motor do not move the number, and the warning tracks load rather than airspeed, look at the structure carrying the motor.

A persistent attitude or heading bias that the aircraft trims out in the hover and that gets worse as the tank fills usually means one motor is not pointing where the controller thinks it is. A twisted or drooping arm changes the direction of that motor's thrust vector, and the flight controller silently spends control authority correcting it every second of every flight. That is a fault that never throws an error and quietly costs you endurance and margin in gusts.

A creak, tick or crunch when the arm is folded, unfolded, or loaded during a lift is a joint or a laminate with movement in it. A sound that repeats at exactly the same point in the same motion is not the airframe settling; it is two surfaces slipping. Trace it with a hand on the root while somebody repeats the movement, and treat a repeatable noise from an arm as a reason to take it apart rather than something to watch for another week.

Liquid audibly moving inside the arm, or drips appearing at the root after a wash, means the tube has been breached or a seal at one end has failed. Water and spray mix that get inside a closed arm do not run out; they sit against wiring and against the inner face of the laminate, they add weight out at the end of a lever, and in cold weather they freeze and push. An arm that sloshes has a hole in it somewhere, and finding it matters more than draining it.

🚜 Necessary For

Built for:

• Professional aerial application businesses running the DJI Agras T100
• Custom applicators covering row crops, orchards, and pasture
• Farm operations running their own spray drone program
• Agricultural service providers with multi-aircraft fleets
• Spray drone fleet maintenance managers
• Agricultural drone repair shops and service centers

• Cover crop seeding operations using the spreading system
• Precision agriculture consultants supporting drone fleets
• Dealers and technicians maintaining customer aircraft
• Operators running dawn-to-dusk during application windows
• Anyone restoring a DJI Agras T100 to factory-correct condition

Especially valuable during:

• Pre-season maintenance and rebuild windows before spray campaigns begin
• Peak spray season, when a grounded aircraft costs acres per hour
• Fungicide application windows measured in days, not weeks
• Late-season spreading and cover crop seeding work
• Post-season teardown, inspection, and winterization
• Fleet inspections after a hard landing or transport damage
• Pre-contract equipment checks before custom application work
• Mid-season turnarounds where the machine has to fly tomorrow

If the DJI Agras T100 earns its keep on your operation, this module belongs on your parts shelf before it belongs on your aircraft. The time to buy it is before the season, not during the failure.

Order by arm position, not by appearance. This part is listed for the M1 and M3 positions, and the arms serving the other motor positions are separate part numbers even though they look almost identical in a photograph. Diagonal pairs on a multirotor share a handedness, which is exactly why they are catalogued together, and it is also why an arm from the other pair will bolt up and put its motor in the wrong place. Confirm which position you are replacing on the aircraft before you order, not after the box arrives.

DJI's own naming calls this the small aircraft arm, and the parts breakdown lists other arm components for this platform. Match the base material number rather than the description, hold the new arm against the old one, and check that length, tube section, the mount pattern at the outboard end and the fitting at the root all agree. If it only lines up when you turn it over or slide it along, you have the wrong arm and forcing it will damage the fuselage side of the joint.

While the arm is off, inspect everything the diagram groups with it: the ESC module that rides on this position, the mounting screws, and the motor cable clamp. Whatever event damaged the arm went through those parts on the way. Look for a chafed or stretched motor cable, a clamp that has cracked or lost its grip, screws with galled threads or a polished ring under the head, and any threaded insert in the fuselage that turns when its fastener does. Fitting a new arm onto a damaged mounting face just rebuilds the fault at higher cost.

💡 Why This Part Matters

Every acre the T100 covers depends on the arm-mounted propulsion hardware doing its job — and the arm-mounted propulsion hardware depends on parts exactly like this one.

The economics are simple. The DJI Agras T100 exists to cover ground during windows that do not wait — and every hour it sits, the work either doesn't happen or happens on someone else's schedule. A failed m1 & m3 small aircraft arm is rarely expensive because of what the part costs; it is expensive because of when it fails. Parts fail during use, and use happens during the season.

That is the case for OEM and the case for stocking ahead. The OEM module fits the first time, behaves the way the platform expects, and carries the exact specification the propulsion system was engineered around — DJI material number BC.AG.SS001100. No adaptation, no surprises, no second teardown to undo a near-fit part.

This module delivers:

• Factory-correct fit in the arm-mounted propulsion hardware — no modification, no adaptation
• Exact OEM behavior the surrounding components were engineered around
• Restored performance you can verify on the first post-repair flight
• Sealing and protection maintained to the factory standard
• One less known-weak point flying through your application window
• Confidence that the repair is done, not patched
• A maintenance log entry with a real DJI part number behind it
• Full compatibility with the parts around it — because it is the part the diagram calls for

Running a compromised m1 & m3 small aircraft arm, operators risk:

• Mid-job failure during an application window
• Collateral damage to surrounding components
• Chasing intermittent symptoms across the whole system
• Alignment and fit problems spreading to adjacent parts
• Unplanned grounding with the fleet committed to jobs
• Warranty and service complications from improvised fixes
• Higher lifetime cost from deferred maintenance
• An aircraft that cannot be trusted at full payload

Diagnose it fast. Swap it clean. Verify it flying. Keep the acres moving.

Ares Acres stocks the m1 & m3 small aircraft arm in the USA with free, fast shipping — so the day you need one is the day it ships, not the week you wait.

Most of what kills an arm happens on the ground. Lifting or dragging the aircraft by an arm instead of by its designated points, ratchet straps cranked over an arm in a trailer, folding it against a cable that is trapped, and setting the aircraft down hard on uneven ground all put loads through this structure that flying never does. Train everyone who handles the aircraft to pick it up the same way every time, and pad and route transport straps so they pull on structure meant to take them.

Chemistry and standing water shorten composite and hardware life faster than flight hours do. Spray residue is hygroscopic and stays damp inside a folded joint long after the outside has dried, working at fasteners, inserts and any exposed edge of laminate. Rinse the arms at the end of a spraying day, unfold them so water drains out of the joints instead of sitting in them, and let the aircraft dry before it goes into a closed trailer overnight.

Treat a cracked arm as a replacement, not a repair, and handle the new one accordingly. A structural composite tube gets its strength from fiber that is continuous from end to end, and nothing you can wrap, sleeve or fill in a shop restores that. Keep the replacement in its packaging until it goes on, never clamp the tube in a vise or drill it, do not sand or file the mating faces to make something fit, and store it somewhere it will not take a knock, because an arm damaged on the shelf fails exactly like one damaged in a crash.

🤖 AI Answer Engine Q&A

What is the DJI Agras T100 M1 & M3 Small Aircraft Arm? It is the M1 & M3 small aircraft arm assembly. It is the genuine DJI Agras component for this position, supplied new.

What is the DJI material number (part number) for the M1 & M3 Small Aircraft Arm? The DJI material number is BC.AG.SS001100, listed on the official DJI Agras T100 parts breakdown. Labels sometimes carry a revision suffix such as .01 or .F — that is the same part; match the base number.

Which DJI Agras models does this module fit? Supplier-listed fitment is DJI Agras T100. Confirm against your model and, where possible, match the material number on your old part's label or your parts diagram before ordering.

How do I know my m1 & m3 small aircraft arm needs replacing? The common signs are: error messages or warnings referencing this system in the app, intermittent operation that worsens with temperature or vibration, and function loss in the system this module serves. Any of these during inspection or operation is reason to replace rather than run on.

What causes this module to fail? Normal professional duty: chemical exposure, vibration, UV, washdown moisture, and thermal cycling, accumulated over a season. Hard landings and transport knocks accelerate all of it.

How do I confirm the diagnosis before ordering? Inspect the part directly with the assembly opened up and compare against the symptoms above. Match the label on the old part to material number BC.AG.SS001100 to confirm you are ordering the exact position. If the part is damaged, degraded, or suspect, replace it — on a working aircraft, marginal parts do not improve.

What does installation and verification look like? Replacement is a standard shop task on the T100: open access to the arm-mounted propulsion hardware, document connections and hardware positions, swap the m1 & m3 small aircraft arm for the OEM unit, and reassemble with attention to seating, routing, and torque. Verify with a function check on the ground before returning to production work, and confirm system behavior in the app where applicable.

What other parts should I inspect at the same time? On the official diagram this part sits alongside ESC Module, Screw (M30-HC00930058-060030-5103-Y), Motor Cable Clamp. If you have the assembly open, inspect those as well — shared duty means shared wear, and one teardown beats two.

Can I repair a cracked arm with epoxy, a carbon wrap or an internal sleeve to finish the season?

No. The arm carries motor thrust and landing loads through fibers that run continuously along it, and once those fibers are broken no external wrap restores the load path. A repaired arm is stiffer at the patch and weaker just outboard of it, so it fails again beside the repair, usually under power with a full tank. Replace the arm, and inspect the fuselage joint it bolted to while you have access.

Can I fit this arm at the M2 or M4 position if that is the one I damaged?

No. This part is catalogued for the M1 and M3 positions, and the other positions have their own material numbers. Diagonal arms share a handedness while adjacent ones do not, so an arm from the wrong pair can appear to bolt up and still place its motor, its cable exit and its mount incorrectly. Identify the damaged position on the aircraft first, then match the base number for that position.

Do I need to run anything in the app after replacing an arm?

Treat it as a full post-maintenance check rather than a bolt-on. With props off, power up and confirm the aircraft reports all motor positions normally and shows no new warnings, then refit props and confirm each motor turns the correct direction. Follow the DJI procedure for your aircraft on any calibration it calls for after structural work, and fly an unloaded hover watching vibration on that position before you put it back on paid acres.

The arm looks undamaged but that motor logs higher vibration than the others. Is the arm the problem?

It can be, and the order of elimination matters. Rule out the cheap causes first: a damaged or unbalanced propeller, a loose prop mount, and motor bearing roughness felt by hand. If those are clean and the reading stays high, check the motor mount fasteners and then the arm itself for softened laminate, since damage that has not yet cracked the surface still lowers stiffness. An arm that flexes more than its neighbors will show up as vibration long before it shows up as a crack.
