I bought the FCX18 LC80 back in March of 2024, but lost access to my printer for about 2 months. This initial log will detail a bit of the FCX18 design and the parts I have installed.

The first free "mod" I did was flipping the front diff housing screws to get a bit more steering angle, there are several guides on youtube that show how to do this.

Thankfully the FCX18 shares a lot of parts with the FCX24 so parts aren't too hard to find or expensive. I installed some metal diff gears from Aliexpress, as I have heard these are one of the first things to break. I also bought some metal portal axle gears, but it turns out the stock gears are metal. 

As designed, the FCX18 is a bit top heavy so I figured I'd get some brass wheels. However, I do like the look of the stock wheels, so I ended up buying these brass internal rings; these replace the plastic rings of the 3 piece wheels. HOWEVER they do not fit out of the box. If you want to go this route, you will need to sand down the inner and outer faces of the wheel until they fit into the brass ring. You will also end up with a slightly wider wheel, effectively increasing the amount of negative offset. I paired these new wheels with some Injora 58x24mm tires.

With wheels and tires, the truck is a little less prone to tipping at high approach angles. The next log will go over my first iteration of new shock mounts that are designed to increase suspension travel.
