Where this data comes from
The rows are Happymodel's own bench table, an HTML table in the body of its 2018 SE0802 1-2S product post on happymodel.cn ("Happymodel 0802 Brushless motors benchmark"), so every figure is the source's own text. The table covers four windings (16000/19000/22000/25000 KV); only the winding this page sells is carried here. It steps CURRENT, not throttle, and prints no per-row RPM, so both columns are empty. Every row's printed power equals Voltage x Current and its printed efficiency equals Thrust / Power. Cell counts are not printed per row: 4.2 V, 3.8 V and 3.7 V runs are filed as 1S, the 7.0 V run as 2S. Prop names are the table's ("4-blades propeller" written singular). Happymodel's block for the line: 9N12P, 8x2 mm stator, 1.0 mm shaft, body Ø10.5x14.9 mm, 1-2S, 1.9 g. No-load blocks for 16000 KV: 0.27 A, 31150 RPM at 1.9 V (16394.7 KV) and 0.29 A, 29710 RPM at 2 V (15852 KV); wire length 40 mm. Peak 43.1 g is the 2S run at 5.00 A.
