Easy to install. I like the space saving of the these 2 in 1 systems. I know on youtube some people said the motor is set opposite direction straight out of the box. I think it depends on how you install the motor. I have it forward facing in my rig and it and do not have the issue. Review: Great for 1/10 crawler - This was the best upgrade for my crawler. The sensor’d motor works awesome and runs cool. Love to run this thing in low speed and watch the truck clime like it’s in granny gear. ## Features - Pro-level Drag Brake performance and adjustability - Compact for easy installation in most applications - Ready to install — no soldering required - Integrated 40A / 160A ESC - Industry leading waterproof design ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09JBCJ2Q8 | | Best Sellers Rank | #245,208 in Toys & Games ( See Top 100 in Toys & Games ) #262 in Radio Control Vehicle Speed Controls | | Brand | Spektrum | | Brand Name | Spektrum | | Customer Reviews | 4.1 out of 5 stars 43 Reviews | | Horsepower | 1400 KW | | Included Components | Firma 2-in-1 Brushless Crawler Motor/ESC: 1400Kv | | Item Type Name | Car Speed Controls & Accessories | | Item Weight | 9.6 ounces | | Manufacturer | Horizon Hobby | | Material | Plastic | | Material Type | Plastic | | Model | SPMXSEM1040A | | Model Name | Firma 2-in-1 Brushless Crawler Motor/ESC: 1400Kv | | Number of Items | 1 | | Part Number | SPMXSEM1040A | | Speed | 1400 rpm | | UPC | 605482769072 | | Unit Count | 1 Count | | Voltage | 7.4 volts | ## Product Details - **Brand:** Spektrum - **Horsepower:** 1400 Kilowatts - **Model Name:** Firma 2-in-1 Brushless Crawler Motor/ESC: 1400Kv - **Speed:** 1400 RPM - **Voltage:** 7.4 Volts ## Images ![Spektrum Firma 2-in-1 Brushless Crawler Motor/ESC: 1400Kv, SPMXSEM1040A - Image 1](https://m.media-amazon.com/images/I/61YE6qiQPjL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ So far so good 👌 *by J***H on September 7, 2022* No complaints so far.
