With the boom in popularity of the WL Toys 144001 1/14 scale RC buggy, there are a lot of aftermarket parts available now, all of which are currently available at here. For this article I'll be looking at why I chose the metal upgrade parts I did, how to install and my thoughts on the parts I did install. 

The first thing you probably think of with metal parts is that they will be stronger than the plastic parts they replace. Although this is true, strictly speaking, the stock plastic pieces do have advantages in some situations, specifically -

1. They are more flexible
2. Have a better bite with screws
3. Can sacrifice a cheaper more easily replaceable part rather than transfer force to a more complex, more expensive or more difficult to replace part

Because of this some parts are well suited to be replaced with metal and some are not. I've chosen the below components to be replaced with metal parts to improve the durability of the car. All parts are available in several colours: Blue, Red, Pink, Gold, Silver, Black.

I've specifically avoided these parts below because I think they will reduce net durability for reasons explained underneath the images. If you are just going for looks however they do still look great!

Plus other parts available with my comments

The WL Toys 144001 is an excellent low cost hobby grade RC buggy that I ordered from Banggood. I've already taken free and low cost steps to improve performance in part 1 and part 2 of my upgrades guide. This upgrade guide here is dedicated to installing a powerful and efficient 2838 brushless system that is optimised for balance, handling and efficiency. It will also be much faster and reliable that the stock system.

As mentioned above the brushless upgrade I am doing here is based on a smaller, lighter more powerful motor than stock so I can get the best handling by reducing weight and improving balance. For this reason I have chosen a brushless 2838 sized motor (28mm diameter, 38mm can length) that runs at 4500kV. This is the same spec powertrain used by the premium LC Racing EMB-1h on which the 144001 is based. The objective is to optimise handling by removing the extremely heavy and power hungry but inefficient brushed 550 motor.

I have not gone with a brushless motor the same size as the brushed 550 (3650, 3652, 3660) as these are really only suited to speed runs although this will be an upgrade I'll do later on with my second 144001.

Benefits from this 2838 brushless setup over stock will include:

• Stronger acceleration
• Higher top speed
• Better front/rear and left/right weight balance
• Lighter overall weight
• Ability to run 2s or 3s safely
• Much better battery life
• Greater crash resistance since car carries less momentum.

This is the second part of my free and budget upgrade walkthrough for the WL Toys 144001. The first part can be found here.

The first series of upgrades I made to the WL toys 144001 was to improve longevity and handling by getting the shock absorber fluid level right, the diffs lubed properly and camber and toe in set correctly. This articles expands on that by further improving the handling through minor tweaks the are either free or cost very little. It is really important you get the handling right to make the car more predictable, especially if you plan on power upgrades further down the line. The upgrades I'll detail in this article are:

1. Decrease the REAR toe in
2. Set the droop on front and rear arms
3. Improve the dampening in the rear shocks 

1. Decreasing the rear toe in
The WL toys 144001 comes set with a LOT of rear toe in (which is the amount the rear wheels point in towards the car when looking from above). Rear toe in does help with cornering stability by decreasing useful steering when powering on in the corner but comes at the cost of straight line speed, especially in high grip situations. In simple terms rear toe in does help make the car feel more stable through corners however I feel the 144001 has much too much and this is easily remedied for free as below:
