motors are a great match for a heavier 3.5-inch setup. They have plenty of power, run smoothly, and handle the extra weight without any trouble. Really solid performance for this size of drone!!

Woow!! Unos motores espectaculares! Me llegaron súper rápido, muy bien empaquetado, y unos detalles alucinantes, volveré a comprar sin dudar. Probé los MEPS SZ1804 2450KV y la verdad van súper bien. Tienen muy buena potencia para drones de 3 pulgadas, sin gastar tanta batería. Se sienten suaves, responden rápido y el vuelo es bien estable. Además, son livianos y no se calientan mucho. La calidad se nota —los rodamientos van finos y el acabado está muy bien para el precio. En general, me sorprendieron bastante, rinden más de lo que esperaba y son una opción muy buena si querés algo equilibrado entre potencia, eficiencia y precio. I’ve been flying the MEPS SZ1804 2450KV motors and honestly, they perform great. Tons of power for a 3-inch setup without draining the battery too fast. They feel super smooth, responsive, and keep the drone really stable in the air. They’re lightweight, don’t heat up much, and the build quality is solid — the bearings run smooth and the finish looks nice for

Ordered the 1804 and realized they were too heavy for my setup. After a few messages they change it and sent the motors I wanted. Took less than 2 weeks from meps to USA. Will order again!
