Abstract
This paper presents an experimental demonstration of the Giant Rotor System (GRS), a heavy-lifting aircraft concept based on the Electric Power Reconfigurable Rotor (EPR²) concept and subsequent studies. The GRS is the first system to successfully demonstrate, under real outdoor flight conditions, the lifting of a payload with two off-the-shelf tethered fixed-wing unmanned aerial vehicles (UAVs). The non-optimized system demonstrated hover flight and slow vertical lifting (less than 1 m/s) capabilities while lifting a 20 kg payload with two 3.2 kg UAVs and a total of 2.1 kW. The lifting efficiency achieved by the GRS is approximately 4 times better than that of any conventional rotorcraft or heavy-lift VTOL system. The results of this study are promising and bring us closer to the reality of using available commercial airplanes for vertical lifting applications. The experimental setup, the control scheme, the flight test results, and a comparison of the GRS performance to that of conventional rotorcraft are described in this paper.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
