WL toys have had a series of hits with the 1/14 scale 144001 and now more recently with the 1/12 scale 124019 and 124018 - same car just a little longer. In order to hit their price point though they have had to compromise on the power train - opting for brushed motor technology that although surprisingly fast offers poor long term durability and even worse efficiency leading short running times. Upgrading to brushless is a solid option but has required hacks and workarounds in the past to get anything other than basic speed run builds. This new guide aims to be drop in solution with no mechanical modification required.

Just to recap I've already made 3 brushless builds. If you have the ability I still highly rate the ultimate brushless upgrade as I believe the motor and gear combination is perfect for fast, reliable and efficient 2s running.

DumboRC have a range of very similar 2.4GHz digital surface radios (for RC car and boats) with subtle differences which makes them confusing to buy. All of them around around the $30 mark which makes them extremely good value if you know how to pick the right set of features for you. In this guide/review I'll break down the differences and review the two variants that I recommend - namely the DumboRC X6 2.4G 6CH Transmitter and DumboRC X6A 2.4G 6CH Transmitter with X6FG Receiver and will of course review them and give you my recommendations.

The WL Toys 144001 is a very fast little 1/14 scale RC car thanks to it's massive 550 brushless motor that powers it with some rather tall gearing. The downside to this is the heat that it generates. Over time this heat can damage electronics and cause a decrease in performance and indeed motor failure. This is a quick and dirty guide to significantly improve motor cooling for less than $2 which should only take 5-10 minutes to do with simple tools.

The WL Toys 144001 is a small 1/14 scale 4wd buggy with a massively oversized brushed motor that can reach well over 30mph. When this massive brushed motor is replaced with a massive brushless motor the top speed can become over triple that with the right setup. The below guide goes into detail the build components I used for such a build, the build process and setup to optimise handling.

By now you've probably seen some wild speed run builds based on the WL toys 144001 of up to and over 100mph. At the top end of the scale these are highly customised with expensive race-oriented gear and outboard twin-battery power supply. The objective of my build was stealth: to retain the stock look, making everything fit (somewhat tightly) under the stock bodyshell and be bolt-on without the need for machining or fabrication i.e. as simple to replicate as possible. For this reason I have specifically chosen to run my car with stock gearing on 2-3s only. To that end here are the parts I chose and why,

I've separated this into power system for the key components...

For those that upgrade to a much larger ESC in the WL Toys 144001 these is often an issue where the fan and or heatsink of a larger ESC fouls against the shell in the stock position. If you don't want to change the shell and don't want to jack it up I have a solution for you.

Although I recommend the 2838 brushless motor/30a ESC upgrade in this article for the 144001 for general bashing, speed runs require much larger ESC that typically have fans installed. In this particular build I used an 80A Flycolour lightning ESC that, although compact, fouls against the ceiling of the 144001 shell. Because this build is for road only I didn't mind a cutout in the shell but wanted it to be tidy and discreet. The easiest way I found to do this is as follows. Remember, click on an image below to embiggen and see all of the pixels

I've now built up quite a library of articles for the WL Toys 144001 (and 124019 / 124018) and thought I would use this page to share them. I've separated here into beginner, moderate and advanced ability but hopefully I have enough information in these guides to make them straightforward enough for anyone to try.

Now that I've had experience with quite a few upgrades and replacements, here are the parts I can actually recommend:

I've now completed a number of articles that have improved the handling, power and efficiency of the WL Toys 144001 and 124018 and 124019 which can be found here: All my WL Toys 144001 /124018 / 124019 upgrade articles. ​The next item I am addressing is the tyres. The stock wheels and tyres (like the rest of the car) are modelled closely on the LR Racing EMB-1h micro pins which are designed for carpet and hard packed dirt racing. Outside of these grip isn't great, and when you take into account the the rubber is firmer on the 144001 tyres then you are left with a tyre that is not really suited well for bashing off-road. In this article I'll explore some better bashing alternatives that shouldn't compromise the rest of the car

Stock tyres have an outside diameter of 72mm which is the same front and rear (it needs to be on a 4wd). Widths are staggered meaning they are slightly wider at the rear - 30mm compared to the front - 26mm. Again typical for a buggy because on acceleration weight transfers to the rear and the extra width provides more grip. Drive on the wheels is provided by a 12mm hex drive which is something of an industry standard on cars around this size

The problem is that a combination of the design and compound of the tyre mean that they don't grip well on the majority of surfaces we run (off road bashing and tarmac). Since the 12mm hex drive is common there are a lot of wheels that physically fit but not a lot that work well because of the uncommon diameter. On to the theory:

Recently I upgraded to brushless power in the WL Toys 144001 as you can see in the below article which is also relevant to the new WL Toys 124018 and 124019:

WL TOYS 144001: ULTIMATE BRUSHLESS UPGRADE GUIDE

Performance is so much better than stock and battery life has increased by over 50%. I much prefer this smaller brushless that the larger 3650 size that are usually limited to on road and speed runs. The install is fairly straightforward but you need to slot the motor mount to set the mesh on the smaller 17t pinion gear and this can be tricky. Good news though, I've found a workaround where no machining nor tricky gear mesh setting is required.

The 144001 uses a 0.7 modulus gear pitch and is very rare for pinions. We are typically limited to the very large stock 27t pinion (way too big for this application) or the 17t pinion from the WL Toys A959 / A969. The 17t pinion offers an excellent ratio for the 2838 and 2845 motors but you need to mod the motor plate as mentioned in my original brushless upgrade article.

Good news though, I've found that using the stock 380 motor mounts on the motor plate you can use a 15t pinion gear. Up until recently these have been impossible to find but I've done a LOT of testing and have found three options for you. 

Option 1: 15t from Hobbyking
Hobbyking still have some old stock of a 15t 0.7m pinion that we used on certain helis but it is not a bolt on option - as it has an oversize 5.0mm bore. Because of this you need a 5mm to 3.2mm reducer which is available here. You may also need to file down the grub screw a little if it fouls on the mount. Please note this may now be out of stock depending on warehouse

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. These upgrades are also applicable to the extended wheelbase 124019 which is identical other than the length

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. This upgrade is fully compatible with the new 124019 and 124018 as well and an excellent option to improve performance and battery life.

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-1 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 - see my speed run build guide if that is the kind of build you are looking for

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.
