UAV motor mounts and propeller adapters — the two propulsion interface parts where dimensional accuracy directly determines rotor performance. Motor mount face perpendicularity to arm axis ≤0.01 mm controls rotor thrust vector; propeller adapter concentricity ≤0.02 mm controls propeller imbalance. Both mass verified to ±3% of design target.
DRN-001
PROPULSION / 001 — FEATURED
UAV Motor Mounts
Brushless motor mounting seats for multirotor, fixed-wing pusher/tractor, and hybrid VTOL UAV propulsion systems. Motor face perpendicularity to arm axis ≤0.01 mm — directly determines rotor thrust vector alignment. Misalignment of even 0.5° generates lateral thrust component and hover bias that must be corrected by flight controller trimming at the cost of control authority and efficiency. Motor bolt-pattern position ±0.005 mm — machined in the same setup as the arm bore to maintain geometric relationship. Integral ESC cable management channel and heat-dissipation slot geometry machined from Al7075-T6 billet. Vibration-damper thread insert pattern (M3 or M4 steel inserts) for anti-vibration motor mounting. Mass verified — target weight ±3%. Hard anodize Type III standard.

Arm Connectors & Frame Skeleton
Quote →
UAV arm connector hub bodies and frame skeleton structures — the primary load-bearing structural elements of the drone platform. Arm socket bore perpendicularity to hub plane ≤0.01 mm determines whether all motor thrust vectors are parallel. Skeleton frames machined as monolithic one-piece structures — replacing multi-part bolted or bonded assemblies and eliminating joint fatigue initiation sites. All parts lightweight-pocketed with FEA-guided geometry.
DRN-003
STRUCTURE / 003 — FEATURED
Arm Connector Seats
Central hub arm socket bodies for quick-fold and fixed-arm UAV frames. Arm bore perpendicularity to hub plane ≤0.01 mm — ensures all arm axes are coplanar, keeping all motor thrust vectors parallel for balanced lift without flight controller compensation. On a quad, even 0.5° arm tilt creates 0.87% lateral thrust imbalance per motor, requiring permanent control surface deflection. Rotational locking geometry and alignment detent machined integral — no separate locking pin assembly to lose or misalign. Clamp force calculated for specified arm tube OD and wall thickness. Compatible with carbon fibre, aluminium alloy, and titanium arm tubes. Mass verified ±3%. Available in fixed-arm and quick-fold configurations.

Payload & Gimbal Brackets
Quote →
UAV camera gimbal housing brackets and sensor payload mounting bodies — where motor axis coaxiality ≤0.005 mm determines smooth gimbal rotation without cogging, and where payload isolation mounting geometry determines how much drone vibration reaches the camera sensor. Thin-wall pocketed design minimises gimbal inertia for faster pan/tilt response.
DRN-005
PAYLOAD & GIMBAL / 005 — FEATURED
Gimbal Bracket Bodies
2-axis and 3-axis camera gimbal yoke and bracket bodies for cinema, survey, inspection, and thermal camera UAV payloads. Motor seat coaxiality ≤0.005 mm — eccentricity in the gimbal motor seat creates vibration that appears in video as micro-jitter at the motor cogging frequency, not filtered by the gimbal control loop. Thin-wall pocketed design — typical wall 1.2 mm in Al7075 — minimises gimbal inertia for faster transient response and lower motor current. Balance optimisation pocket geometry removes material from the heavy side to shift CG to gimbal rotation centre. Camera mounting face flatness ±0.01 mm. Vibration isolation damper mount pocket pattern for anti-vibration ball or rubber mount. Custom camera platform sizes (Sony, FLIR, Zenmuse, custom sensor modules).

Why UAV Parts Need
More Than General Precision Machining
⚖
Mass Verification — ±3% of Design Target
Every UAV structural part weighed against the design mass target. Deviation >3% triggers DFM review — not silently delivered. On a 500 g UAV, a 15 g motor mount (3%) vs 14 g target is acceptable; a 20 g mount (33% over) affects hover time and balance symmetry. We measure, not assume.

🎯
Motor Perpendicularity ≤0.01 mm — Thrust Vector Control
Motor mount face perpendicularity ≤0.01 mm to arm axis — machined and verified by CMM. Even 0.3° motor tilt generates lateral thrust component requiring 5% constant control deflection. On a quad, four misaligned motors reduce effective payload and drain battery. We measure perpendicularity as a functional specification, not a cosmetic tolerance.

FEA-Guided Lightweighting — Stiffness Not Sacrificed
Pocket geometry designed from FEA output or our DFM-suggested lightweighting — removing material only from low-stress regions identified by load analysis. Not random pocketing that may weaken the part at an unconsidered load case. For flight-critical structural parts, we request or generate basic load case analysis before lightweighting.

🧲
Non-Magnetic Materials for Flight Controller Mounts
Flight controller plates machined from Al6061 or Al6063 — both verified non-ferromagnetic. Steel fasteners within 20 mm of magnetometer are replaced with aluminium, nylon, or titanium. Compass heading accuracy degrades with nearby ferromagnetic material — a problem that appears in flight as heading drift and is often misdiagnosed as firmware issues.

Vibration Isolation Pockets — IMU & Camera
Anti-vibration grommet and rubber mount pocket geometry machined to specified mount OD for correct press-fit compression and optimal vibration isolation. Pixhawk and DJI standard 30.5×30.5 mm and 45×45 mm patterns available without drawing — custom patterns to drawing in same lead time.

Hard Anodize Type III — Wear on High-Cycle Parts
Motor mounts, battery rails, and arm connectors are assembled and disassembled hundreds of times. Hard anodize Type III (400–600 HV, 25–75 μm) on aluminium provides wear resistance that bare or Type II anodized aluminium cannot — preventing thread damage, mating surface wear, and galling on frequently swapped parts.

Material Selection
Materials for UAV & Drone Parts
UAV material selection is dominated by stiffness-to-weight ratio — every extra gram reduces payload and hover time.
MAT / 01
Al7075-T6
503 MPa · 2.81 g/cm³ · Best Strength-to-Weight Al
Standard UAV structural alloy. Motor mounts, arm connectors, gimbal brackets, and frame skeletons. Hard anodize Type III standard. 30% stronger than 6061 at essentially same weight — no reason to use 6061 for structural drone parts.
MAT / 02
TC4 Ti-6Al-4V
ASTM B265 Grade 5 · 950 MPa · 4.43 g/cm³
Premium UAV structural material where Al7075 mass budget is still exceeded — motor mounts and arm connectors for long-endurance drones where every gram of structural weight reduces mission battery. 57% higher specific strength than Al7075.
MAT / 03
Al6061-T651
310 MPa · 2.70 g/cm³ · Non-Magnetic · T651
Non-magnetic, stress-relieved plate for flight controller and avionics mounting plates where FC IMU and compass must not be disturbed. T651 eliminates post-machining bow. Standard for all FC and autopilot mount applications.
MAT / 04
Al5052-H32
228 MPa · 2.68 g/cm³ · Best Corrosion Resistance
Best corrosion resistance of all aluminium alloys — used for battery mounting frames on marine, agricultural spray, and high-humidity environment UAVs where 7075 may pit. Also used for outer skin/fairing sheet panels on fixed-wing UAVs.
MAT / 05
PEEK
100 MPa · 1.32 g/cm³ · Non-Magnetic · Insulating
For electrically isolating FC mount standoffs and ESC mounting plates where galvanic isolation between the power electronics and the airframe is required. Also used as landing gear tip pad — impact-absorbing and electrically isolating. Lightest option where strength requirements allow.
