### ⭐⭐⭐⭐⭐ Works great!

Quick shipping, good price and performs well

### ⭐⭐⭐⭐⭐ Drop in and drive
*by J***N on March 12, 2026*

Perfect replacement for the 1/18 scale hbx. I use a 30amp hw esc and 3s lipo so I added a fan. A plus that it is a direct drop in up and running in 10 minutes . I will need another since i over power it 😏

### ⭐⭐⭐⭐⭐ Great Upgrade
*by D***. on November 14, 2024*

Used this motor to upgrade my son's car (model 18858). It is much faster and less likely to cease, as the motor is fully closed. The brushed motor that originally came with the car was brushed and had an opening that allowed sand to get trapped inside. Overall, very happy.
