The WL Toys 124016, 128017 & 124018, a 1/12 scale RC car that was produced in late 2020, is nearly identical to the wildly successful WL Toys 144001. Even though I said in my review that the 124019 had some noticeable improvements, a little bit of straightforward setup and adjusting can make this much better. The best way to configure and optimize your 124019 to get the most from it without spending any money on upgrades other than consumables like grease is covered in this article.

1. Reducing the rear toe to a more neutral position (free upgrade)
   The 124019 has significant rear toe in as it leaves the factory. By introducing a little understeer, this improves cornering stability, but the effect is minimal, and as a result, straight-line speed is reduced. The good news is that a more neutral setting for the rear to in may be simply adjusted as shown below.
2. Toe and camber should be adjusted to a more neutral position (free) Just take a look at the picture below of my car right out of the box to see how poorly the front toe (the angle the wheels point in or out) is adjusted from the manufacturer. But since this automobile has adjustable tie rods, the problem is simple to solve. The plastic cups that ultimately bolt to the car have opposite threads on them, one regular and one reverse, so that when you twist the shaft while both cups are straight, both loosen (get longer) or tighten (get shorter) at the same time. This allows you to lengthen or shorten the tie rods without removing the cups from the ball joints. Good in theory, but poorly implemented in this case because the cups pop from the ball mount on the car when the shaft is rotated. However, let’s get started. The steering rack should be squarely in the middle because this will serve as your center of reference. Install the batteries so that your automobile is properly balanced with the shocks loaded. Select a tie-rod that needs adjusting, then remove it. You’ll see that the rod is asymmetrical, with a reverse thread on the plastic cup closest to the hole and a conventional thread on the one farthest from it. Utilize this knowledge to adjust the length as necessary. Always make an effort to adjust both ends roughly equally.
3. Grease your differentials
4. The shock oil level has to be adjusted; mine was OK. A pleasant relief following the dangerously overfilled shocks in my 144001 that I fixed in this article, the shock fluid level in my 124019 was excellent. The images below show that I was able to accomplish full compression with no signs of hydrolock or air bubbles. Bravo, WL Toys!
