Tool
AUW calculator
All-up weight shapes handling and can affect which operating rules apply. Plan it here before ordering, then weigh the finished aircraft: this calculator is not a legal determination.
This is a planning tool. It combines published weights where available with explicitly named estimates and allowances. Those figures are not the finished mass. Before flying, weigh the complete aircraft in flight configuration and trust the scale.

EU readers: For a privately built aircraft, the EU Open A1 route requires maximum take-off mass including payload below 250 g and maximum operating speed below 19 m/s; all other applicable Open Category and national requirements still apply. Weight alone is not permission to fly. Check the EASA privately built drones FAQ and your local authority.
