Arbitration Result

Status
completed
Resolved Value
1.57
Positive Spin
✓ Optimized for stable and efficient flight with 1.57-inch propellers.
Reasoning
Multiple high-confidence sources support 1.57 inches (BetaFPV official site noting 1.57 (40mm) and Oscar Liang's review with 1.57). The conflicting 1.22 inches appears in one lower-confidence source. Therefore, 1.57 inches is the most supported value.
