Sub-250g 4-inch Quad — Throttle Sweep

ThrustLab couples a multi-fidelity propeller solver (validated against the UIUC wind-tunnel database) with a motor, ESC, and battery model to predict thrust, power, efficiency, and temperatures at the chosen operating point.

Yes. Create a free account, pick your battery, ESC, motor, and propeller, and run the same physics on your own powertrain in seconds.

Engineering aid — ThrustLab results are physics-based estimates, not certified data. Always bench-test and independently validate before committing a real build to flight. Not for safety-critical or certification use.
