QUADIFYRC RC Car Review and Upgrade Guides

The WL toys 1/14 and 1/12 scale cars are fanstastic value and offer a myriad of options for tinkering and modding. One area where they are woefully inadequate though is gearing. They have chosen a very uncommon mod 0.7 gear pitch meaning there are very few options outside of stock because the standard 27t or even the more recent 19t offer very tall gearing only. In this gearing guide I have laid out all known available options in this guide to help you get the most out of your car.

Let's start this conversation by saying that the stick spur gear for these cars (44 teeth) is fixed - an immovable object with no alternative options*. Thus it is only the pinions we can change to alter gear ratios. Next we can say that motors with a 36mm diameter (ie stock 550 brushed, 3650 brushless, 3652 brushless and 3660 brushless cannot move closer to the top brace and therefore cannot use a smaller pinion, even with this adjustable mount. This with these motors you can use the stock 27t pinion only and the tall gearing (4.074:1)

This means that the only way to alter gear ratio is to use a smaller motor suck as a brushed 380 or 390 or a brushless 2440, 2445, 2838, 2845, 2850. This is a good thing because for the brushless motors in particular they are smaller, lighter, faster, more efficient and run cooler but with less torque they need the smaller pinions which provide shorter gearing. This is the basis of every brushless upgrade I have written which provide a much more well rounded performance for these cars. Anyway lets go directly to the options readily available.

*Custom made Mod1 spurs are available, talk to Michael Koebbe on the QuadifyRC facebook group.

The WL Toys 144010 is a brushless 4WD 1/14 scale RC Car. It comes ready to run (RTR) meaning that everything except 4 x AA batteries for your transmitter is included. My tests have shown this car to be extremely quick and I will share all of that information and more in this review. In addition to this I have also added a section for tuning tips and other RC cars to consider in this category.

WL Toys is a Chinese-based manufacturer of RC cars that has been really popular over the last 2-3 years because of the great balance of price, speed and handling. The 144010 I am reviewing here is based on the same car that was released back then but has had 5-6 rounds of iterations with multiple improvements since that have culminated in a very well rounded car. This latest iteration includes all of those improvements and the latest brushless power system from WL Toys making it extremely quick as well. In fact I'd go so far as to say that you cannot buy faster for cheaper. Below I will break down the main systems of the car and will then give you quantified tests results plus my own opinion and finally my recommendations. Grab yourself a drink or bite to eat and let's get started.

The ISDT AIR8 charger is a DC powered battery charger made by ISDT. It is capable of charging lipos and batteries of all chemistry at up to 500W (up to 20a) using an industry leading user interface with multiple idiot-proofed systems. This is the first charger that supports BATTAIR - a new technology that allows you to retain battery specs and charge history with a lightweight and low cost balance connector that connect to a phone app via blue tooth

For this review I will start out with the charger itself first before I cover off the BATTAIR TECH and how it allows the battery to interface with the app
