Firma 4274 1900Kv 4-Pole Brushless Motor: 5mm

Spektrum Firma 4274 1900 Kv 4-pole brushless motor – 5 mm shaft

For 1/8 buggies, truggies and monster trucks on 3S-6S LiPo. The Firma 1900 Kv has a 4-pole rotor with 8 magnets and low cogging, a CNC-machined aluminium can, insulated high-purity copper windings and a 5 mm hardened steel shaft on precision ball bearings. It is matched to the Firma 130 Smart ESC, and 4 mm gold-plated bullet connectors are fitted at the factory.

The Safe-D shaft has a groove for a c-clip so the pinion does not slip – a smart touch when the going gets tough.
