// FAQ

Common questions.

From compliance and procurement to integration and firmware. See also: Compliance Glossary

Is the QuadDrive 80A NDAA compliant?

Yes. The QuadDrive 80A is compliant with NDAA §848 FY20, §817 FY23, the American Security Drone Act FY24, and Executive Order 13981. Every unit ships with a Certificate of Conformance and full supply-chain traceability documentation.

Where is it designed and manufactured?

The QuadDrive 80A is designed and manufactured in the United States. It qualifies as a domestic end product under the Buy American Act and meets Trade Agreements Act requirements for federal procurement.

What is a "covered component" under the NDAA?

Under NDAA §848, a covered component is any drone part — including ESCs, flight controllers, cameras, radios, and data transmission devices — manufactured or substantially transformed by a covered foreign entity (primarily Chinese companies on DoD's Section 1237 list). Federal drone programs cannot use covered components regardless of branding or country of final assembly. Full definition →

Why are Chinese ESCs prohibited for federal programs?

NDAA §848, §817, and ASDA prohibit federal agencies from procuring drones or covered components from entities linked to China, Russia, Iran, and North Korea. The concern is supply-chain compromise: a malicious ESC at the power stage could affect vehicle control or enable data exfiltration. The prohibition applies regardless of branding or distribution channel.

What is the difference between §848 FY20 and §817 FY23?

NDAA §848 (FY2020) first restricted DoD from procuring covered drones and components. NDAA §817 (FY2023) strengthened those restrictions, tightened the definitions of covered entities, and added operational restrictions on existing inventory. Together they form the layered DoD prohibition that ASDA FY2024 then extended to all federal agencies.

What is the American Security Drone Act?

The American Security Drone Act (ASDA), enacted in the FY2024 NDAA, extends covered-UAS restrictions from DoD to the entire federal government. It prohibits all federal agencies from procuring, operating, or using drones or covered components from listed foreign entities, with an operational ban taking effect December 2025.

What is the Blue UAS Framework?

The Defense Innovation Unit's Blue UAS Framework is the DoD's pre-vetted list of drones and components cleared for procurement. Inclusion requires an independent supply-chain and cybersecurity review by DIU in coordination with DCMA. Lirith is currently pursuing Blue UAS listing for the QuadDrive 80A.

What control protocols are supported?

PWM, Dshot 300/600, CAN, and Ethernet, with bidirectional telemetry reporting RPM, current, voltage, temperature, and orientation per motor.

What platforms is it compatible with?

Group 1 (under 20 lb) and Group 2 (21–55 lb) sUAS including tactical quadcopters, FPV strike platforms, short-range ISR drones, and medium-endurance multi-payload platforms. Compatible with ArduPilot and PX4.

Is it compatible with ArduPilot and PX4?

Yes. The QuadDrive 80A is validated with both ArduPilot and PX4, the most widely deployed open-source flight stack platforms for Group 1 and Group 2 UAS. Integration guides are available to qualified customers.

What motor sizes does it support?

The QuadDrive 80A supports 2204–5008 brushless DC motors on 4S–6S battery packs, covering the full performance envelope of Group 1 and Group 2 sUAS quadcopter and hexacopter configurations.

What firmware does it run?

AM32 — an open-source, US-developed firmware supporting Dshot, bidirectional telemetry, and CAN. BLHeli is also supported. Neither firmware is manufactured or controlled by a covered foreign entity.

Does it have per-motor telemetry?

Yes. The QuadDrive 80A reports RPM, current, voltage, and temperature per motor via bidirectional telemetry, giving the flight controller and ground station real-time performance and health data for each motor independently.

Is it compatible with FPV systems?

Yes. The QuadDrive 80A supports Dshot 300/600 and PWM protocols used by FPV flight stacks. The BEC outputs (3.3V/3A, 5V/3A, 12V/1A) can power cameras, video transmitters, and other FPV peripherals without a separate power distribution board.

How do I buy or evaluate the QuadDrive 80A?

Contact sales@lirith.com to start a qualification conversation. We'll discuss your platform and program requirements, then provide pricing, lead times, and the documentation package. Evaluation units are available for qualified US drone manufacturers.

Does Lirith sell direct or through distributors?

Direct only. Direct supply ensures full supply-chain traceability and documentation integrity — requirements that distribution channels cannot reliably maintain for NDAA-compliant programs.

What sets Lirith apart from other ESC suppliers?

Lirith is one of the few US manufacturers of domestic electronic speed controllers purpose-built for NDAA compliance. We design, assemble, coat, test, and package entirely in the United States; every component is sourced from non-covered-entity vendors; and we ship a full compliance documentation package as a standard part of every program.

What documentation is available?

Qualified customers receive a Certificate of Conformance, Country of Origin letter, NDAA compliance documentation, Bill of Materials, performance and test results, traceability statements, 3D CAD model, 2D integration drawing, heat sink integration guide, and an ArduPilot/PX4 integration guide.

Is Lirith registered in SAM.gov?

Contact info@lirith.com for current procurement and registration status. We work directly with procurement offices to ensure all necessary registrations, certifications, and documentation are in place.
