Where this data comes from

The rows are BetaFPV's own load-performance sheet image on betafpv.com/products/1103-brushless-motors-aquila20, headed on the page "Load performance of the 1103 Brushless Motors": one winding (10500 KV) on one prop (GF 2218-3) at 2S, nine throttle points 20-100% in 10% steps, with the voltage sagging 7.94 -> 7.82 V under load. It is the 2026-line template the 0702 (2026) sheet uses - a published Speed (RPM) column, a per-row voltage and no Coil temp column - not the struck-through-RPM shape of the 0702 II and 0702 sheets. Identity with our RaceDayQuads listing and with BetaFPV's own spec block is five figures to the digit: the 1103 stator, 10500 KV, 3.5 g +/-0.1 g, a O1.5 mm shaft 5 mm long and 2S (4.2 V x 2); the table's Model cell reads "C23 P1103-10500KV". Max thrust is 142 g, the 100% row, where the page carried none. No spec-block cross-check is possible here: unlike BetaFPV's 0802 (2026) and 1102 (2026) blocks, this product's block states neither a Maximum Power nor a Maximum Current. Three source facts recorded rather than repaired. First, the 20% row's Input is 2.26 W where its own Voltage x Current is 7.94 x 0.29 = 2.30 W (the printed power implies 7.79 V); every other row reproduces V x A inside the two-decimal rounding of its own columns. Second, the 30% row prints 4.03 g/W where its own 26 g over 6.33 W is 4.11 - the Thrust column is an integer and 25.5 g / 6.33 W is 4.03, so the efficiency is computed from an unrounded thrust; both rows are inside check_thrust.py's band and nothing was reconstructed. Third, the outline drawing's own inch conversion for the shaft is wrong by a factor of ten ("1.5mm/0.6in" beside "5mm/0.19in", "13.8mm/0.54in" and "13.6mm/0.53in", which are all correct). That drawing gives the motor as O13.6 x 13.8 mm overall, 8.8 mm of body plus the 5 mm shaft, on a 52 mm 30AWG lead with the connector included; the spec block puts three M1.4 screws on a 6.6 mm hole distance, which is a bolt circle and not a mount span, so mount_mm stays empty. Recommended props are BetaFPV's own Recommended Parts entry for the page, replacing our derived whoop-prop class. This is BetaFPV's only 1103 product - our other 1103 page, betafpv-1103-micro-whoop (8500/11000 KV), has no sheet anywhere on the brand's site.
