QUADIFYRC RC Car Review and Upgrade Guides

The WL Toys 124019 is a 1/12 scale RC Car released late 2020 by WL toys and is largely identical to the hugely popular WL Toys 144001. Although the 124019 did however have some notable improvements as covered in my review, a bit of simple setup and tuning can improve this much more. In this guide I will cover how to best setup and tune your 124019 to get the best out of it without spending anything on upgrades other than consumable items like grease.

I've already written over a dozen guides on improving the 144001 here which are applicable to this car as well but I wanted to use this guide to be very specific on the exact improvements I made since the manufacturer has fixed some of the issues mentioned in my 144001 guides here and here.

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 124019 is a 1/12 scale Ready To Run (RTR) radio controlled 4wd off road buggy which I will be reviewing in-depth for this article. It is an evolution of the hugely popular WL Toys 144001 1/14 scale which it shares over 95% of it's part with. It's also the same under the hood as the 124018 sand buggy. I have a lot of experience with these series of cars having written over a dozen guides which can be seen here so apologies in advance if I get a little technical (skip to the conclusions if needed!).

WL Toys scored massive success with the 1/14th scale 144001 which based heavily on the LC racing EMB-1 and released in early 2019 - it was well made with good components as well as being fast and durable. Perhaps more importantly it hit a great price point of $80-100 USD. With popularity came a large amount of upgrade parts and people like me have taken this further to adapt brushless systems to suit this car for off-road fun and even for speed run build capable of 80-100mph. The 124019 is the subject of this review though and in essence this is just the same as the 144001 except for a wheelbase that has been stretched by 45mm. This is at least how it looks on the surface but there are a number of key improvements that many have missed and these have addressed: motor overheating, differential durability, chassis stiffness and wheel security. I'll cover these all in detail here plus feedback on the cars performance, handling and durability as per a typical review.

Right folks, I've gotten back into RC cars in a big way this year (over 20 articles on RC cars!) and after all I've reviewed and modified I thought I'd list my favourite value for money RC cars for 2020. As a scientist in real life I can say this list is thoroughly unscientific and if you got me on a different day the order may be different but I'll at least share with you why I just what I did and in which order so you can see what things are important to your decision. Roughly speaking I'll cover off the key areas that make budget RC cars so much fun - speed, battery life, handling, durability and ability to customise/mod.
