Manufacturer bench figures (BrotherHobby bench (2018-2023 sheets), 8 throttle points (30-100%) per winding on one prop each; 400KV on 8S and again on 12S, 480/640/900/970/1050KV and both 1200KV runs on 6S, 1520KV on 4S); real-world thrust varies with ESC, battery sag and prop condition.

Where this data comes from

BrotherHobby publishes ten Tornado T5 3115 PRO Test Reports; our listing sells the 400 and 1050 KV windings, whose blocks give 212.00 and 34.00 mOhm and 110.00 and 108.00 g with cable (16# 300 mm), against the 110 g our retail source prints. Every block states a 31.00 x 15 mm stator, 12N14P and N52H; the 900 KV sheet's lamination is nippon 1500# where the others are Kawasaki 1200# 0.2 mm. Two source facts recorded rather than repaired: the 400 KV HQ 9X5X3 sheet is headed 12S and states 220.00 g - twice the 110.00 g the 400 KV 8S sheet states for the same winding, and above the 5-8S our listing sells - and the 1200 KV drawing calls out 18AWG 250 mm leads where its own block says 16#, 300 mm. Peak thrust 4480 g is the 1200 KV 9.0*4.7 run, a winding our source does not sell
