GEPRC EM3110 900KV Motor

The GEPRC EM3110 is a 900KV brushless motor built for 6S long-range and heavy freestyle quads, sized for 8–10 inch propellers where a large 31mm-diameter stator does the work at low rpm. The low 900KV winding suits pilots who want long flight times on 6S with big, slow-turning props rather than the high-rpm response of a 5-inch race build.

Key features

• 3110 stator (31mm diameter) gives a large magnetic area for torque on 8–10 inch props, so the motor swings them without over-revving
• 900KV on a 6S pack (22.2V nominal) keeps prop tip speed and current draw in the efficient band for cruise and mapping flights
• 5mm shaft with an M5 threaded prop mount, taking standard M5 nut-on props directly
• 19x19mm four-hole mounting pattern, the common bolt spacing on long-range frame arms
• Rated to 1480W max and 57A peak current, so the manufacturer recommends a 60–80A ESC

Pair four of these with a 6S 60–80A ESC and 8–10 inch props for long-range cruising; check that your arms are drilled 19×19mm and that the arm plate clears a 33mm bell before ordering. Motors are sold individually.
