Product overview

The Flash Hobby A1207 is a compact brushless DC motor for propeller propulsion, supplied as one motor with mounting screws. Its 15.7x13.8mm body weighs 10.3g including cables and contains a 12mm-diameter, 7mm-high stator in a 9N12P configuration. Construction combines an NMB bearing, a 7075-T6 aluminum bell and 0.15mm silicon steel laminations. Integration dimensions include a 2.0mm shaft, a 9*9mm mounting pattern specified as M2*4, and 115mm motor cables in 26#AWG. The package contains four M2X5mm and eight M2X7mm screws.

Motor selection spans 2500KV, 3100KV, 5200KV, 6000KV and 7000KV, with custom KV also offered. The 2500KV and 3100KV configurations specify 3 inch propellers; the higher-KV configurations specify 2 inch propellers. Suggested ESC capacity is 10A~20A throughout. Voltage specifications are 16V(4S) for 2500KV through 6000KV and 12V(3S) for 7000KV. Maximum pull varies by configuration from 244g to 445g. Electrical load also depends on the propeller and throttle: the 3100KV motor with GF3028 reaches 125.4W at 90% throttle and 15.99V.
