RotorLabYour custom heavy-lift rig is a real aircraft now, and the production, the insurer, and the studio safety officer all want its airworthiness story before it flies over a set. RotorLab gives a fleet of exactly one the same machinery a manufacturer gets: measured performance instead of a spec-sheet guess, a frozen design baseline, and a dossier with a verification code.
Build the rig in the Builder: motors, props, pack, payload. The physics engine computes thrust margin, hover time and power draw from published, cross-checked equations, for sixteen airframe layouts including coax and X8 heavy lifters.
Fly a hover with your telemetry streaming and live calibration inverts the model: figure of merit and maximum thrust measured from your aircraft's own data. The numbers in the dossier become the aircraft's, not the catalog's.
The finished design freezes as a type: parameters and approved performance, hashed at freeze time. One aircraft is enough; the point is that the configuration that got qualified is the configuration on record, and drift from it is visible.
The airworthiness dossier renders with the baseline, the measured performance, the declaration matrix you signed, and a verification code anyone on the production side can check. Repairs, batteries and every flight keep landing on the same record afterward.
RotorLab documents your aircraft's qualification; it does not issue airworthiness approvals. What it gives you is the evidence trail that makes your claim easy to accept.
