Carbon-fiber airframe tubes
A replacement arm can match the outside diameter and still fail to seat correctly in the existing clamp. Wall construction and cut-end quality belong in the purchasing specification.

Airframe & structure
Browse airframe & structure by interface and service requirement. Open an individual reference for the information needed to evaluate a sourcing request.
CNC-cut airframe plates
Top plates, bottom plates and arm junctions need their own revisions. A visually similar outline does not establish hole alignment or load-path equivalence.
Folding arm joints
Hinges and locks must fit the same arm and center-body revision. The procurement decision includes retention parts and wear items, not just the visible hinge block.
Landing gear and skids
Ground clearance, mounting fit and aircraft mass determine what to request. A taller leg also changes how the aircraft sits and how loads enter the frame.

What belongs in a UAV mechanical RFQ?
A drawing-led inquiry gives suppliers a common definition of the part. An attractive rendering does not resolve hidden holes, datums or acceptance tolerances.
Reviewing a proposed material substitution
Two quotations can share a part name while using different materials, finishes or composite constructions. Price comparison should start by exposing those differences.
First-article review for machined UAV parts
The first delivered sample should answer whether a supplier understood the released specification. It should not become an informal prototype with undocumented changes.
Service hardware for cargo UAV projects
Cargo aircraft can introduce different geometry, duty and maintenance patterns. A broad drone-parts label is too vague for sourcing a structural item.
Compare mechanical quotes without losing the specification
The cheapest line item can omit finishing, inspection, tooling or the hardware needed for assembly. Quote comparison should expose the delivered scope.
