Key features of the Spektrum M-SPMXSM4100
- 4700Kv output – delivers high RPM for rapid launches and top-end speed
- Sensored control – enables smooth throttle modulation and low-speed precision
- Low-cog 4-pole rotor – enhances efficiency and reduces startup hesitation
- 5mm hardened steel shaft – supports robust gearing and resists drivetrain stress
- CNC aluminum housing – improves heat dissipation and structural integrity
- Precision ball bearings – ensure smooth rotation and long-term reliability
Why is this motor ideal for Losi LMT monster trucks?
The Spektrum M-SPMXSM4100 brushless motor with 5mm shaft and 4-pole rotor design is specifically tuned for the Losi 1/10 LMT platform, offering the power and control needed for competitive monster truck action. Its 3662-size format fits perfectly into the chassis, while the sensored operation allows the ESC to match throttle input to motor RPM with precision. This results in smoother launches, better cornering control, and more predictable handling—essential for both racing and freestyle bashing.
How does the rotor design enhance performance?
The Spektrum M-SPMXSM4100 with low-cog 8-magnet rotor and CNC aluminum housing uses a 4-pole configuration to deliver torque-rich output and efficient power delivery. The low-cog design minimizes resistance at startup, improving throttle response and reducing wear on drivetrain components. Combined with high-purity copper windings and precision bearings, the motor maintains consistent performance even under heavy load and extended run times.
What makes this motor a smart upgrade?
The Spektrum 4700Kv motor for precision throttle control and smooth acceleration is an ideal replacement for stock brushed or lower-Kv brushless motors in 1/10 scale monster trucks. Its sensored design ensures compatibility with advanced ESC systems, enabling telemetry support and fine-tuned control. Whether you're chasing lap times or launching off ramps, this motor delivers the responsiveness and durability needed to push your rig to the limit.

We want to make sure your delivery goes smoothly, so here are some important details about our service:
- For orders above £120, we offer delivery to most mainland UK addresses. For orders under £120, we can still deliver to Northern Ireland and the outlying isles, as long as the item can be sent by Royal Mail, weighs less than 30kg, and fits within 61cm × 46cm × 46cm. Some highland and remote areas may carry an extra delivery charge as couriers often apply surcharges in these locations. If you live in one of these areas, feel free to contact us before ordering so we can confirm the delivery options and costs for you.
- Most of our products include delivery in the price. If your order is under £90, a small delivery fee will apply but do not worry this will always be clearly shown at checkout before you complete your purchase.
