FAQ

Common questions

Do you supply datasheets and 3D models?

Yes. PDF datasheets, pinout drawings and STEP files are available for every product on the site. Ask with the SKU and we send the package the same day.

Can I get samples before a bulk order?

Samples ship at list price with express cost at your account. For OEM programmes the sample cost is credited against the first production order.

Is firmware locked?

No. Flight controllers ship with a standard Betaflight / INAV target and are reflashable. We publish the target name and the pin mapping.

Do you handle certification for my market?

Registration and corporate documents are not released. For each shipment we issue the commercial paperwork and the transport files the carrier requires, including MSDS and UN38.3 for cells. Market-specific approvals are the buyer's responsibility.

What about radio spectrum rules?

High-power transmitters and amplifiers are sold to licensed operators and OEMs only. It is the buyer's responsibility to confirm that the power and band are permitted in the destination country.
