GEPRC GR2004 1750KV Brushless Motor

The GEPRC GR2004 1750KV is a 16.8 g brushless motor for ultralight 4–5 inch toothpick and long-range FPV builds, rated for 2S to 6S. This winding has a 1.5 mm shaft with a two-screw T-mount, so it takes T-mount propellers such as the HQ T5x3 — not props held by an M5 nut.

Key features

• 12N14P layout with N52H magnets for strong torque from a 20 × 4 mm stator.

• Dual bearings and a dynamically balanced bell for smooth running.

• 16.8 g per motor, light enough for sub-250 g 4–5 inch frames.

• More than 1 kg of thrust per motor on 6S with a two-blade 5-inch prop.

Bench data at 24 V (6S)

• HQ T5x3 two-blade: 500 g at 7.34 A, peak 1044 g at 18.42 A (441.5 W)

• Gemfan 5125 three-blade: 450 g at 7.31 A, peak 943 g at 21.05 A (505.4 W)

Peak draw on 6S is about 18–21 A per motor, so pick an ESC with headroom above that. GEPRC's full test table and dimension drawing are below; the figures are bench results for reference.
