1604 Motors

1604 Motors Collection is designed for high-performance 3.5-inch FPV freestyle drones, especially sub-250g builds that require a balance of power and lightweight structure. Leading products in this series include the T-Motor P1604 2850KV/3800KV, Hypetrain Let’s Fly RC 1604 4000KV by Rotor Riot, and MEPS SZ1604—trusted names among micro drone racers and freestyle pilots.

These motors typically feature:

  • KV Ratings: 2850KV (6S), 3800KV (4S), and 4000KV (3S–4S)

  • Weight: Around 11.5g–12g with wires

  • Voltage compatibility: 3S to 6S

  • Mounting pattern: 9×9mm, M2

  • Shaft diameter: 1.5mm

  • Peak thrust: Up to 618g (as in T-Motor P1604, on 6S with 3.5" props)

These motors are best paired with 3.5" props and 130–160mm wheelbase frames, commonly used in agile freestyle drones like the iFlight ProTek R35, Diatone Roma F35, or custom toothpick-style builds.

Ideal for tight, dynamic flying environments, the 1604 motor class offers punchy acceleration, smooth throttle response, and efficient cooling—making it a favorite in indoor freestyle and light cinematic builds.
