A build option for micro FPV quads
The BOOMFPV（炸机大叔） 1103 brushless motor on this page is the 10000KV version, featuring a blue-and-silver body with a slender plain shaft. The main photo, specs, and close-ups are shown in the nine-photo set above.
A small motor — check the fit before you install it
The data lists a 2–3S working voltage, a weight of 4.15g, a 14.2mm outer diameter, a 10.5mm body height, and a 1.5mm shaft diameter. The configuration is 9N/12P, with 28AWG leads, 65mm long. Before installation, check frame space, the propeller bore, the mounting method, and screw length. The current dimension drawing does not list a mounting-hole pitch; confirm that on the actual motor.
Read the electrical figures with the test conditions
The photos list 155mΩ phase-to-phase resistance, 0.61A no-load current at 7V, a maximum current of 9.44A, and a maximum power of 117W. The maxima are not a continuous rating. The photo set does not list full load conditions or duration. When you choose an ESC and battery, check them against the specific propeller, load, and cooling.
2 inch is a reference fit
This motor can be used as a reference choice on 2 inch micro FPV quads. Actual fit still depends on the propeller, all-up weight, frame, and ESC. The detail photos above show the body colors, the plain shaft, and the windings, so you can check appearance and connection space when you choose parts.
