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:

We've now had the SG 1602 brushless RC Truck (same as SG 1601, HBX 16889) for 6 months and it has been abused several times per weekend by my 5 year old (and myself!) in that time. I'm delighted to say that it is still running, still fast and I haven't needed to buy any spare parts. So far the list of casualties are:

• The rear spoiler. This was the first to go when my son kept reversing in to things.
• On of the front LED headlights. Continual front on crashes into solid objects at speed have damaged a wire. It's an easy fix but I am lazy! (Update, just fixed it last night)
• On of the tyres has become unglued in one spot on one rim but was an easy fix with some cheap super glue, the stuff that is like 99c for 6 packs.

So, as you may be able to see, this fast and light truck has taken an incredible amount of abuse and has very little damage to show for it, even then the damage is purely cosmetic. So what are my thoughts on the good and the bad of this now and my more recommendation based on the additional experience? Read on:

Firstly, "must do" is a bit strong and a bit of a pisstake of the clickbait Youtube videos out there. With that said I do strongly recommend them if you can to get the best performance out of you car and extend it's life. I've arrived at these recommendations by comparing the 144001 directly to the car it was copied off - the excellent LC Racing EMB-1h plus basic fundamentals of rc car operation of which I've been around for years. 

Sorry for overly long title. I've now had the Surpass Hobby 3650 sized 3900kv brushless motor and 60A ESC Combo for about 3 months now and have thoroughly tortured it in a very large 1/10 scale 4wd short course truck (brushed version of the DHK Hunter here) for this review. With these electronics you can easily upgrade any 1/10 scale hobby grade rc car to brushless which for the uninitiated offers significantly more power, efficiency and if done right, durability over their brushless counterparts. This stands true for on-road tourers, pan cars and offroad buggies, SCTs, trucks (2 and 4wd). The only cars this would be unsuitable for is where very fine control is required - drift and crawlers come to mind. Read on for install and review. 

A look at the gear
The kit is very simple - a 4 pole brushless 3650 sized motor (540 in brushed terms) and a 60a ESC. The motor I reviewed is 3900kv which is a good all purpose size on common 2s batteries. The ESC is another simple waterproof affair with built in cooling fan. They are both waterproof according to the specs but personally I haven't and would not put the ESC to the test. The ESC can be programmed with common features but does require this programming card to change. Parameters that can be changed are:

The SG 1602 Brushless RC truck is a 1/16 scale 4wd off road truck/buggy (truggy) that has a powerful and efficient brushless motor/esc system. Note, this appears identical to the HBX 16889 and shares the same parts. It is available from Banggood for less than $90 and as little as $70. I've had one of these for about 2 months now and for the times that my son lets me drive it I've had quite a few runs to get a good feel of performance and durability. My full review is below.

What's in the box?
Actually this is pretty well equipped:

• The Truck (4wd brushless 1/16 scale)
• 2.4GHz remote
• 2s 1300mah li-ion battery
• USB charger
• LED Headlight system (for user to install)
• Wheelie bar (for user to install)

In order to get this running you'll need 4 x AA batteries for the transmitter. These 2.4GHz transmitter are extremely efficient so you'll get good battery life even with cheap alkaline batteries. As mentioned above there is a nice set of headlights and wheelie bar included and these are very simple to install with well laid out instructions.
