🔧 Component Overview
The DJI Agras T100 / T70P Original Large Rear Aircraft Arm is a primary structural load-bearing component of the airframe. This is not a cosmetic part — it is the mechanical backbone that transfers thrust, payload stress, and vibration loads between the motor system and the central fuselage.
If your rear arm assembly is compromised, bent, cracked, or fatigued, the aircraft is no longer airworthy for commercial operations. This is a mandatory replacement item, not an optional upgrade.
⚙️ Functional Purpose
This rear arm is responsible for:
- Motor thrust transfer into the fuselage
- Payload and spray load distribution
- Vibration isolation for the rear propulsion assembly
- Flight geometry stability under acceleration and braking
⚠️ Common Replacement Indicators
Damage to this arm directly causes:
- Motor misalignment
- Uneven thrust vectors
- ESC thermal strain
- Flight instability under heavy payload
Once stress fractures begin, structural failure escalates quickly — especially during full-tank missions.
📐 Specifications
- Component Type: Large rear aircraft structural arm
- Position: Rear motor + propulsion mount
- Compatibility: DJI Agras T100 / T70P
- Material: Reinforced aviation-grade alloy & composite blend
- Function: Primary load-bearing flight frame structure
- Packaging: Single OEM structural arm, boxed
Inspect before installation:
- Confirm the new arm is free of shipping damage and true along its length
- Inspect the arm connector, motor mount, and fuselage joint for hidden impact damage
- Review the structural alignment orientation reference before assembly
After installation:
- Verify all fasteners are torqued to spec and the arm locks fully
- Confirm motor alignment and propeller clearance by hand before power-up
- Run an unloaded hover test, then a partial-load test, before returning to full-tank missions
🚜 Necessary For
This is a required stock component for any professional operator running heavy payload cycles. This is not optional inventory for:
- Commercial spray contractors
- Multi-drone fleet operators
- Repair centers servicing crash recovery units
- Farms operating full-capacity chemical loads
- Technicians rebuilding impact-damaged frames
If you do not stock rear arms, you accept forced downtime after any rear impact event.
💡 Why This Part Matters
Rear arm failure causes:
- Propeller misalignment
- Vibration feedback into cameras, RTK, and payload boards
- Accelerated motor bearing wear
- ESC overheating
- Spray pattern instability
Replacing the arm restores proper thrust alignment, load symmetry, structural rigidity, and long-term propulsion reliability. This single component protects motors, ESCs, payload boards, vision systems, and flight controller integrity.
Carry the thrust. Hold the geometry. Protect the airframe. Stay airworthy.
