Flight Controllers & Avionics

The brain of the aircraft deserves more scrutiny than any other line on the bill of materials. We source flight-controller stacks, GNSS and RTK positioning modules and industrial avionics factory-direct from Shenzhen — and specify them with the judgment of a group that engineers its own.

Scope of Supply

Three disciplines of avionics.
For OEMs, integrators and distributors.

01

Flight-Controller Stacks

Industrial flight-controller stacks for UAV platforms — from single-board controllers to stacked FC-and-power configurations. We match the controller to the airframe, the payload and the mission profile, not to whatever is on the shelf.

02

GNSS & RTK Positioning

Positioning modules from standard GNSS receivers to RTK options for applications where precision is the point — surveying, inspection and repeatable autonomous flight.

Industrial Avionics

The supporting electronics that make a platform dependable — evaluated as a system, so the components you receive are ones that work together, not merely ones that ship together.

Engineering Credibility

Specified by people
who build them.

Our affiliated brand Lthunder engineers its own flight controllers. That work stays inside the group — which means the avionics we trade are evaluated with in-house engineering eyes, not passed along on a distributor's word.

About our brands →
  • Datasheet claims are read against design experience — we know which specifications matter in flight and which exist only on paper.
  • Positioning fit is assessed for the application: standard GNSS where it suffices, RTK where the mission demands it.
  • Interface and integration questions are raised before quotation, so what arrives connects to what you have built.
  • Documentation is treated as part of the product — a controller without a usable wiring reference is an incomplete shipment.

Common Questions

Before you specify.
Two answers buyers usually need first.

Yes. Integration questions route to our engineering desk — pin-outs, positioning-module pairing and platform fit are reviewed before we quote, and deeper support is available through our Engineering & OEM capability.

Controllers ship with their factory firmware images. Configuration support is arranged case-by-case, depending on the platform and the scope of the order — raise it in your inquiry and we will confirm what applies.

The most consequential component.
Specify it with counsel, not a catalog.

Send your platform requirements — controller, positioning, interfaces — and a structured quotation returns within 24 hours.
