QUADIFYRC RC Car Review and Upgrade Guides

The WL Toys 124019 is a small and fast car out of the box - it'll do 55km/h on the old technology brushed motor that comes stock out of the box. For bashing and off-road I prefer to upgrade with physically smaller and more efficient brushless motors but if straight-line on road speed is your objective as is the case here, then using a 3650 sized motor can get you massive speed... there are many examples where this car can go well over 100mph. The objective of my build here is to see what kind of speed I can get without pushing the budget or modifications too far - bolt in parts, stock body and a car than is as reliable as stock and can easily be converted back.

For this build I've chosen the WL Toys 124019 which is a long-wheelbase version of the popular 144001. The reasons this car makes for a good speed run build is:

1. It's cheap - around $100-$120
2. It has a fairly strong and efficient 4wd drive line
3. The comparatively massive brushed motor can easily be replaced with a comparatively massive brushless motor
4. The long wheelbase allows for more room for large components (namely ESC and motor)
5. The car is relatively durable with low cost replacement parts

Let's get on to the build which I have broken down into sections. We'll start with the powertrain which most of you are here for but I'll also cover important lessons in wheel/tyre choice, suspension set up, aero, speed measurement and driving technique. Read on for more

As we all know by now the WL Toys 144001 (and 124018 / 124019 by extension) is a budget copy of LC Racing EMB-1 that utilises cheaper materials and electrical components to make it a lower cost offering. LC Racing spares for the EMB series are surprisingly cheap - often cheaper than the WL toys parts. In the list below I've made it clear which parts are a direct fit and which parts will fit with a little modification.

Link below are to the AliExpress store that I trust - they have been running successfully for over 7 years and will ship worldwide. You may of course have other options locally like Troy Remy in Canada (find him in the QuadifyRC Group), Warren RC in USA, RCMart out of Hong Kong and direct from LC Racing themselves.

The WPL C24 1/16 2.4G 4WD Crawler Truck Is a highly realistic 1/16 scale radio “crawler” RC truck. It has proportional steering and throttle (forward and reverse) and has a huge list of upgradable parts making it a legitimately hobby grade vehicle. Being a crawler it runs at low speed but is very powerful = this in combination with 4wd, grippy tyres and large suspension range makes it very capable in scaling obstacles. Best of all it is extremely cheap - less than $50 with everything you need to run. In this article I will review this truck in full

The small scale crawler market has really taken off recently based on the following because they can be used in so many ways:

• Small scale and low speed means you don’t need to travel to find fun spots to run – in your backyard, local park or even inside your house or garage. This also makes them really suitable for beginners
• Price is very low for a hobby grade car
• Reaplcement parts are inexpensive
• There is a huge range of upgrades – more powerful motors, metal parts, grippier wheels with weights and even a 2 speed gearbox controlled by a third channer
• Even stationary the plastic moulded body looks fantastic and is very presentable even as a scale model of the legendary Toyota Hilux
