Why is the FIRMA 1200Kv motor ideal for SCX6 and other 1/6 crawlers?
The Spektrum M-SPMXSM3100 1/6 crawler motor for SCX6 with 3.5mm bullet connectors is specifically sourced to match the demands of large-scale platforms like the Axial SCX6. Its oversized 5684 can size provides the physical torque and thermal capacity needed for extended crawling sessions. The 1200Kv rating balances speed and control, making it ideal for technical terrain and scale realism. With a 750W output on 3S LiPo, this motor delivers the power required for steep climbs and heavy rigs without sacrificing finesse or responsiveness.
How does FOC control improve crawling performance?
The Spektrum M-SPMXSM3100 sensored brushless motor with FOC control and magnetic encoder utilizes Field-Oriented Control to deliver ultra-smooth throttle response and consistent torque across all RPM ranges. This technology ensures precise rotor positioning and eliminates cogging during startup, which is critical for low-speed crawling. The integrated magnetic encoder provides polarity-protected signal output, maintaining synchronization between motor phases and ESC input. This results in a more natural driving feel and improved control over technical terrain.
What makes this motor durable in harsh environments?
The Spektrum M-SPMXSM3100 with waterproof sensor wire and locking gasket plug is built to withstand the rigors of outdoor crawling. Its CNC-machined aluminum housing offers excellent heat dissipation and structural integrity, while the waterproof sensor wire ensures reliable signal transmission even in wet or muddy conditions. The locking plug and gasket prevent moisture ingress, protecting internal electronics and maintaining performance. Combined with precision ball bearings and a hardened steel shaft, this motor is ready for extreme environments and long-term use.
How does the rotor design affect torque and control?
The FIRMA 1200Kv motor with 4-pole rotor and CNC aluminum housing features a sintered 4-pole, 8-magnet rotor that enhances torque output and rotational smoothness. This design minimizes vibration and maximizes efficiency, especially under load. The rotor’s construction supports consistent power delivery during climbs, descents, and throttle transitions, making it ideal for scale crawling and rock racing. The CNC aluminum housing not only protects the rotor but also aids in heat management, ensuring stable performance over extended runs.
Is this motor compatible with common ESC setups?
Yes. The Spektrum crawler motor for 2S–4S LiPo setups with 750W output on 3S is designed to pair seamlessly with the Spektrum FIRMA 120A Sensored Brushless Smart Crawler ESC (required for optimal performance). The motor’s 3.5mm gold-plated bullet connectors match standard ESC terminals, and the wire color coding simplifies installation. With support for 2S to 4S LiPo batteries, users can tailor their setup for torque-heavy crawling or higher-speed trail runs, depending on terrain and preference.
Why is this one of the best sensored motors for large-scale crawlers?
For drivers seeking precision, durability, and scale realism, the Spektrum M-SPMXSM3100 FIRMA 1200Kv motor with 5684 can size and 5mm hardened steel shaft delivers on all fronts. Its advanced FOC control, waterproof sensor integration, and high-quality rotor design make it a standout choice for SCX6 and other 1/6 platforms. Whether you're building a competition rig or upgrading for trail performance, this motor offers the torque, control, and reliability needed to dominate technical terrain.

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.

Orders are dispatched Monday to Friday only. Some items may take a little longer and if that is the case we will always show the expected delivery time on the product page.
- If your order includes items with different dispatch times we will normally wait and send everything together once all items are in stock. If one of the items is going to take a while we will give you the choice either wait for everything to arrive or let us send the available items now and deliver the rest later. It is up to you.
- We use trusted delivery partners to make sure your order gets to you safely and on time. We use DPD for next working day deliveries and Royal Mail for the 2 day option.
- As soon as your order is on its way we will send you a tracking number by email. If you provide your mobile number at checkout we will also send delivery updates straight to your phone so you can keep an eye on progress.
- If a product is marked as "Dispatched within 3 working days" delivery usually takes around 3 to 5 working days from when your order is placed.
- For customers in Inverness and other parts of the Scottish Highlands deliveries can take up to 2 working days even if you select next day delivery as couriers do not currently offer a guaranteed next day service to those areas.
