Product overview
The Happymodel EX1103 KV11000 is a brushless motor for Mobula8/Bassline. Its physical architecture uses a 9N12P configuration with an 11mm-diameter stator measuring 3mm long. The motor measures 13.5mm in diameter by 15.5mm in length, has a 1.5mm-diameter shaft and weighs 3.8g. These dimensions define the motor body and shaft interface for integration. The product is a motor component, with a specified battery range of 1–2S LiPo.
Bench figures pair the motor with a 2023R propeller at 7.4 V. Across nine operating points, current rises from 1.07 A to 9.20 A and thrust increases from 23 g to 121.9 g. Power rises from 7.92 w to 68.08 w, while efficiency declines from 2.905 g/w to 1.791 g/w. These figures describe that voltage and propeller combination; the highest listed thrust is an operating point within that configuration.
