The WL Toys 144002 1/14 scale RC Monster Truck is a recent release from WL Toys setup as a monster truck and based on the hugely popular 144001 buggy which I have extensively reviewed, modified and tuned in over 40 guides here. This newest version looks to be better suited off-road with the larger wheels and has a number of improvements that are not noticed at first glance. Here I'll review the car in full and let you know what I like about it and what I don't like about it (+how to fix it)
The 144002 is now the 7th time the original 144001 platform and gear have been recycled by WL toys and I've reviewed them and modified every step of the way. In case you are wondering:
This summary is simplified but all along the way WL toys have been making evolutionary improvements to poorly setup or weak points of this car meaning that this latest truck is very much improved over the original 144001. I will of course detail these in the review. Sadly there are still some fundamental flaws too which I will also outline. Let's have a closer look at the car before we take it for a drive so we know what we are dealing with. I'll break this down into sections of power train, driveline, suspension, steering, body and chassis to give it a bit of structure. Then, I'll follow up with a full review of the performance in all areas (including GPS-measured top speed) and my conclusions and recommendations.
The HBX 901a 1/12 brushless truck as reviewed here is a brushless 1/12 scale desert buggy and one of my favourite RC cars of 2021. It was light yet very durable with a very efficient power system and drive train. Short gearing ensured very lengthy battery life and ensured motor and ESC temps remained extremely low with the preference of strong acceleration over top speed. In this article I'll show you how to install a larger 14t pinion gear and talk about the performance improvements.
In my original review I mentioned that the motor mount for this car had preset motor holes that should allow the fitment of a 14t pinion and recommended the Surpass Hobby M0.6 13-17t pack. I can now confirm that these do fit as expected - see the images and steps below to do this yourself - it is very easy and takes around 5-10 minutes.
