Which build is for me?
Five questions turn flying space, local constraints, goggles, budget and footage goals into a first-build and second-build path.

Build planning tools
Start with the kind of flying you want, test the weight, then inspect the parts. These tools expose the book's planning data; they do not turn changing specifications, stock or regulations into guarantees.
2 Plan the weight
AUW calculator
Combine a frame, electronics, video system and battery into an estimated all-up weight before buying. Replace estimates with measured values as your build becomes real.

Bill of materials
Filter the book's curated component catalogue by build path and video ecosystem. Prices and availability are snapshots, not a live retailer feed.
Open Bill of materialsMeasure and verify before flight. A calculated weight is a planning estimate, being below a mass threshold is not by itself proof of legal operation, and a listed component may have changed. Check the finished aircraft, current manufacturer documentation and the rules where you fly.
