Happymodel EX0802 19000KV Brushless Motor – UDL Spec Ready (1S, 1.7 g)

Spec class performance in the lightest package.

The Happymodel EX0802 19000KV is a proven choice for Ultra Drone League (UDL) spec racing and other competitive 1S builds. At just 1.7 g, this is one of the lightest 0802 motors available, giving pilots the perfect balance of thrust, efficiency, and agility on tight indoor tracks.

Its Unibell design improves crash durability, while the double E-clip system prevents bell separation — a common failure point in hard racing conditions. Combined with smooth dynamic balancing and high KV output, the EX0802 is built for consistent, repeatable performance round after round.
