WUQ Firma Brushless Motor 1250Kv 6.5mm Bullet SPMXSM1200

SKU CH-KTG6-W7EDW

Brushless motor rated at 1250Kv with 6.5 mm gold-plated bullet connectors and a 5 mm hardened steel shaft for 8S LiPo setups

  • TypeModels & Kits
  • 1250 Kv motor delivers high-speed performance for 8S LiPo setups
  • 5 mm gold-plated bullet connectors preinstalled for quick ESC connection
  • 4-pole 8-magnet rotor design reduces cogging for smoother throttle response
  • CNC-machined aluminium housing with insulated copper windings enhances durability
  • Hardened 5 mm steel shaft on precision bearings ensures reliable power transfer

Ideal Upgrade for ARRMA Limitless

This brushless motor is a direct upgrade for the ARRMA Limitless Speed Roller. It suits builders of larger scale models who want to run an 8S LiPo powered setup. The 1250Kv rating matches the demands of high-voltage applications. It is not for buyers who need a lower Kv motor for smaller scale or lower voltage platforms.

Simple Connector Installation

The motor arrives with 6.5 mm gold plated bullet connectors already fitted, so no soldering is required for the ESC link. Precision ball bearings and a hardened steel 5mm shaft support smooth rotation from the first run. Installers must ensure the motor mount pattern matches their chassis before tightening. Incorrect gear mesh or loose mount screws are the usual causes of vibration.

1250Kv Rating Defines 8S Suitability

The 1250Kv constant determines the RPM per volt and makes this unit the correct match for an 8S LiPo supply. CNC machined aluminium housing, insulated high purity copper windings and a low cog 4-pole 8-magnet rotor design deliver high efficiency. It is perfectly matched to the Firma 160 Smart ESC for reliable power delivery.

Questions about this item

How do I confirm the 1250Kv motor runs correctly after installation?

Verify smooth rotation of the 5mm shaft, check that the 6.5mm gold bullet connectors are secure, and ensure the 4-pole rotor delivers consistent power with an 8S LiPo and Firma 160 Smart ESC.

What comes with the motor and what must I supply separately?

The motor includes preinstalled 6.5mm gold bullet connectors, precision ball bearings, hardened 5mm shaft, CNC aluminium housing and insulated copper windings; you must provide an 8S LiPo battery and a Firma 160 Smart ESC.

Which Kv version suits an 8S LiPo setup in a large-scale model?

The 1250Kv variant is designed for 8S LiPo power in larger scale models and is matched to the Firma 160 Smart ESC.
