COMPONENT SYSTEM 01 / 4 PRACTICAL CHECKLISTS

PropulsionBegin with the interfaces.

Start with aircraft mass, motor count, target thrust per motor and your intended duty cycle. A motor rating alone does not describe a complete propulsion setup.

A purchasing guide, not live inventory. Use these checklists to describe your requirements. We review candidate parts, supplier information and commercial terms for your project; your technical team confirms the final fit.

01 / PROPULSION

Motors

Generate thrust as part of a motor–ESC–propeller combination.

Request part options : Motors

01 Parameters to provide

  • Supply voltage / cell count and KV target
  • Continuous and peak thrust or power, with duty cycle
  • Propeller diameter / pitch and rotation direction
  • Motor mount pattern, shaft / adapter and mass limit
  • Cooling, ambient temperature and test conditions

02 Still to confirm

  • Thrust and efficiency evidence for the proposed combination
  • Actual thermal margin, bearings and motor lead termination

Review these points with the supplier against the exact proposed part.

02 / PROPULSION

Electronic speed controllers

Control motor speed and deliver power between the battery and motor.

Request part options : Electronic speed controllers

01 Parameters to provide

  • Battery voltage range and continuous / peak current
  • Command protocol and flight-controller interface
  • Motor type, motor lead connections and firmware needs
  • Cooling method, mounting space and mass limit
  • Telemetry, braking and power-output requirements

02 Still to confirm

  • Current ratings under the intended cooling conditions
  • Firmware support, signal levels and startup behaviour

Review these points with the supplier against the exact proposed part.

03 / PROPULSION

Propellers & blades

Convert motor torque into thrust for the intended operating point.

Request part options : Propellers & blades

01 Parameters to provide

  • Diameter, pitch, blade count and rotation direction
  • Hub bore, bolt pattern and motor adapter
  • Material, folding / fixed format and mass limit
  • Intended motor RPM range and thrust requirement
  • Clearance envelope and balance / inspection needs

02 Still to confirm

  • Permitted operating limits and balance evidence
  • Actual fit, paired rotation sets and replacement traceability

Review these points with the supplier against the exact proposed part.

04 / PROPULSION

Propeller hubs & adapters

Connect a propeller or folding blade set to the motor shaft or rotor.

Request part options : Propeller hubs & adapters

01 Parameters to provide

  • Motor shaft diameter and mounting pattern
  • Propeller bore / bolt pattern and blade-root geometry
  • Thread size, direction and retention method
  • Assembly envelope, material and mass limit
  • Required drawing tolerances and load assumptions

02 Still to confirm

  • Fit across the exact motor and blade revisions
  • Retention, hardware specification and assembly instructions

Review these points with the supplier against the exact proposed part.

MAKE THE ENQUIRY ACTIONABLE

What to send with your brief.

An incomplete brief is fine. Mark unknowns clearly so they can be resolved before a purchase decision.

  1. Project contextCivilian application, destination, operating conditions and your integration role.
  2. Part definitionManufacturer and model / revision, or a non-confidential custom-part summary. Note acceptable alternatives; agree sharing arrangements before sending detailed drawings.
  3. Procurement needsQuantities, required date, sample or production intent, and documentation / inspection expectations.
  4. Interfaces & evidenceConnected hardware and software, existing drawings, and the test or acceptance evidence your team needs.

FROM YOUR REQUIREMENT TO A SUPPLY PROPOSAL

Send the requirement.
We’ll coordinate the options.

Share the part reference, quantity and destination. We’ll review sourcing feasibility, request the missing details and work towards a quotation with clear inclusions, lead time and supply responsibilities.
