Build the ultimate indoor cruiser with the Sub250 M1 0803 16500KV Micro Motor. Designed specifically for 1S toothpick builds and tight-space freestyle drones, this high-efficiency brushless motor delivers an exceptional thrust-to-weight ratio. Weighing in at a feather-light 2.2g, it keeps your 1.4-inch to 1.6-inch micro quads incredibly agile and responsive.
Smooth Indoor Freestyle
While higher KV motors are built for raw speed, the 16500KV variant is tuned specifically for smooth control, low-vibration setups, and general-purpose indoor flying. It provides a highly manageable throttle curve, making it much easier to navigate tight hallways, hit small gaps, and execute precise freestyle maneuvers without accidentally blasting into the ceiling.
Versatile Prop Compatibility
This motor features a classic 1.0mm shaft, giving you maximum flexibility when it comes to choosing propellers. It is compatible with a massive variety of popular micro and whoop props on the market, allowing you to easily tune your drone’s flight characteristics to your exact preference.
Efficient & Durable Design
Built to last, the M1 0803 features a durable 9N12P stator wrapped with high-temperature copper windings. This low-loss, high-efficiency design ensures the motor generates very little heat, providing consistent power delivery and longer flight times on standard 1S LiPo batteries. It is the perfect match for frames like the Sub250 Whoopfly16 and Nanofly16.
