We supply flight controllers, video transmitters, cameras, motors and GNSS modules from audited partner factories — built to our specs, checked by our QC team, shipped from our own stock. Our own production facility breaks ground this year, commissioning in 2027. Consistent batches, honest specifications, and an engineer on the other end of the email.
Everything that sits between the battery and the goggles, sourced from one supplier so a build does not stall on three different lead times.

A power figure on a box is a marketing number. We publish the test that produced it, and we keep the fixture that ran it.

Six lines that move every month. Stocked in depth, with the documentation your customers will ask for.






Schematic, layout, firmware and test fixtures are all ours. Production runs on partner lines, but a change request never leaves our own bench.
Same BOM, same supplier, same fixture. You reorder in March and get the March build, not a silent substitution.
Commercial paperwork, HS codes, battery-safe packaging and EXW Shenzhen as the standard delivery term to the EU, UK, US, Gulf and ASEAN.
Model, quantity, destination. We send a quotation with lead time and a sample price.
Spec sheet, pinout and firmware target confirmed against your build before anything is made.
Units from the production fixture, tested and shipped by express. Report included.
Batch build with 100 % functional test, burn-in on request, photo report before dispatch.
Private label from 100 units. Full re-spin from 1,000. We keep the tooling, you keep the customer.

Germany, UK, France, Poland, Czechia, Spain — EXW Shenzhen, forwarder nominated by you.
United States, Canada — UPS / FedEx consolidation weekly.
UAE, Saudi Arabia, Qatar, Turkey — air freight to DXB and RUH.
Japan, Korea, Australia, Singapore, Malaysia, India.
Send the drawings, the target price and the volume. Our engineering team replies with a feasibility note inside one business day.
