The 1103 high-speed aircraft model brushless motor, KV value is 15000, is commonly used in high-speed micro crossing aircraft, circle machines, and other aircraft models, or as a modification for micro fixed wing aircraft models. The high-speed outer rotor has dynamic balance correction, neodymium magnetic steel or arc-shaped high-efficiency magnetic tiles, a standard shaft with a diameter of 1.5mm, and the fixed part of the outer rotor is thickened with steps.
The motor is suitable for operation in 1-2S lithium batteries, depending on the size of the blade you match. The recommended blade size for 2S is GF1635-4/GF1610-2/GF1608-3, and it is recommended to install it upside down. The front installation may be a bit loose. For 1S, the recommended blade size is GF1636-4.
Thrust test data (GF1635-4 for blade), 1S voltage: 50% throttle 22g, 75% throttle 41g, 100% throttle 50g.
2S voltage: 25% throttle at 26g, 50% throttle at 54g, 75% throttle at 85g, 100% throttle at over 100g.
Recommended racks: Mobula7 standard mount, ACK75 inverted mount, beta75pro, toothpick machine, and most commonly used three hole racks.
Generally, an electric regulator can use around 10A for 1 second, and 15-20A is recommended for 2 seconds. Note that some brushless electric regulators have poor compatibility with ultra-high KV, cannot move up or down at high speeds, or have light jitter. The current is abnormally large and may directly heat up and burn the motor. Pay attention to starting small current actual testing. If the Blheli electric regulator parameters are incorrect, they can be adjusted before use.
The total length of the motor output line is about 40mm, and the motor weighs only 3 grams.

Motors received in good condition. The package had adequate protection. Motors are real tiny! Will have to find an esc/prop to match it.

Excellent little motors – not sure the kv is 15000 but they are resonably powerful on 1s and very strong on 2s. Well packaged in bubble wrap. Does not come with screws (m1.4 4mm)

Owsome motor. Works great with a tiny controller from the same seller.

Surprisingly good motors, after a few test flights using 1 and 2s batteries on 1610 gemfan propellers i have to admit they are an amazing choice for budget build. I cannot comment on their durability for now, but it looks promising.

The motor is very quiet and really only weighs 3 grams. In the test, it runs smoothly without vibrations.
In use, he still needs to prove himself.
