A02Motor arms

Connect each motor to the central frame.

Manufacturers & products

Arms carry motor thrust and impact loads back to the frame. They are revision-specific structural parts, even when different frames share a nominal propeller size.

American sourcing options appear first. A U.S. company or distributor label does not establish U.S. manufacturing. The origin notes identify the specific evidence and any limits.

manufacturer

DragonPlate / Allred & Associates

Carbon sheet for custom arms

Sheet laminates and machining support for an independently designed arm. [6]

U.S. manufacturing claim

Carbon-sheet production is explicitly stated as Elbridge, New York; fiber and resin origin is not established. [6]

Program / application

Upstream material; no stock-frame fit established [6]

Published manufacturing site: Elbridge, New York, USA

Custom program inquiry

Public product catalog; confirm the selected variant and current fulfillment directly. No stock or delivery promise is made.

manufacturer

Lumenier

QAV-S 2 Bardwell SE replacement arm

Single replacement arm; the listing notes a length difference from the original QAV-S. [2][1]

U.S. company

U.S. company in Sarasota, Florida. Product listing identifies manufacture in China; U.S. brand ownership does not change that origin. [2][1]

Program / application

Company location: Sarasota, Florida, USA

Online catalog / ordering

Public product catalog; confirm the selected variant and current fulfillment directly. No stock or delivery promise is made.

Product scope & qualifications
  • The listed V2 arm also fits V1, but has a different length; do not mix revisions without checking geometry.

What remains unverified

  • Commercial spare-arm pages seldom publish bending, fatigue or impact test data.

Where it comes from

A company address is shown separately from a published factory location. Request the manufacturing site and lot traceability for the exact part when sourcing.

What to compare

  • Root geometry

    The arm root, key and clamp must match the center plates.

  • Motor pattern

    Compare bolt circle or square spacing and bolt diameter; these are different conventions.

  • Thickness

    Thickness changes stiffness, fastener engagement and motor clearance.

  • Arm length

    Length changes wheelbase and the swept propeller envelope.

  • Laminate orientation

    Fibers must support bending and torsion, not merely match an exterior weave.

  • Mass and symmetry

    Compare matched arms so replacement geometry and mass remain consistent.

  • Wire protection

    Account for motor-wire routing, guards and propeller clearance.

  • Spare revision

    Check front/rear and left/right applicability before treating a spare as interchangeable.

Selection & integration notes
  • A replacement that fits a bolt pattern can still change wheelbase or propeller clearance.
  • The DragonPlate entry is material supply, not a substitute arm sold for either listed frame.
