TLR 8IGHT-E 4.0 | Build report, pictures and review

The TLR 8ight family has a new member, the TLR 8ight-E 4.0. This new car is the successor of the former 3.0 version which we loved so far (and still do). Horizon Hobby has send us one of the very first kits which we have build last days and hereby our review and pictures. Here we go!

The box and contents

Before GLS was in front of Planet Losi Racing's door we didn't know how the box looks like. As TLR addicts we love the boxes and store them from every car we build (do you?). So we were curious about the box design and this time the car of TLR Team Driver Philip Atondo has the honor to be printed on top of the box. That's an honor!

After you cutted the warranty seals there are a huge number of bags in the box. All tagged and the labels are corresponding with the pick order when you follow the manual during the build. Because this kit is all about a competition buggy the tires and electronics aren't included. But the yellow and white disc rims are in the box so you are able to glue the wheels of your choice on them. We love it to build the chassis and choose the setup of your choice. This is a huge benefit in comparison with Ready to Run models we think.

After we saw the chassis plate and body we were surprised how wide this car is. It is so much wider than the 3.0 version of this electric powered buggy (see picture below with the body). When you have read our article of this car after the release you know this has everything to do with the variable center diff position. We will discuss this later to clarify what is does.

The build of the 8ight-E 4.0

We have builded several 8th scale TLR kits and it's always a pleasure, nothing different this time. The manual is very clear and we have chosen a setup for high grip Astro tracks which we have plenty available here in the Netherlands. That is completely off from the standard setup by the way. The recommended setup by TLR is an all round setup which will work most of the time but as said our tracks are really high grip and to keep all 4 wheels on the ground our suspension is much softer for example.

We have also build the nitro version of this 4.0 chassis in the past and when everything is completed you will notice that it isn't as smooth as the 3.0. This has everything to do with the booted driveshafts but we love this new feature to add extra durability to the car. We know some guys are keeping the boots in the box but this part will prevent your drivetrain for wear so we don't understand why some guys are doing that. With the nitro car we had already some racing days and it will definitely loosen up so the car will run smoother after some hot laps. This is also with the steering. The spindles aren't that smooth and some drivers are drilling the holes an 0.5mm extra to get a smoother steering. But the opposite is that there will be play after some time and we hate that. We will run this car in the out of the box state and will break in everything correctly.

With the new 4.0 electro version you are able to run the car in battery forward configuration. This wasn't possible with previous models and TLR introduced this with their latest electric Truggy. And now also available in the buggy and that's really cool. You may run the battery forward to get more weight in the front so this will result in better cornering and weight balance when taking airtime. We have definitely chosen to run the Dynamite lipo right behind the front wheels. It is easy to change the battery to the rear of the chassis by the way.


The above video shows you the different center diff positions. This is a completely new feature in the 4.0 e-buggy and we like it a lot. This is the feature to make the decision much easier to replace your 3.0 buggy. What is it? Well you can now change the angle of your differential in two different variants. First you can run the center diff in an 0° angle, this is the same setup as the 3.0. A negative of this is that the rear center driveshaft is in a straight line and the center front shaft in an extreme angle. This is why more power is transferred to the rear side of the car and it will act like a 2wd sometimes. To experience a complete 4wd car you are now able to change the center diff into a 4.4° angle by replacing the bottom insert. Now both driveshafts have the same angle and the power is even between front and rear. Of course we have chosen the 4.4° setup because of the high speed and high traction tracks which we have here :-)

When driving a narrow track with lots of corners you probably choose the 0.0° insert.

  • Optional: Arm guards (LOSA1721​)
  • Optional: Front top brace aluminium (LOSA4440​)
  • Optional: Aluminium servo arm
  • Optional: Aluminium servo saver top (TLR244021​)

Last words and final pictures

​We still have much fun with the 3.0 version of the TLR e-buggy and now we are looking forward to get the 4.0 on track. Unfortunately the weather in the Netherlands isn't that good and we can't visit an outdoor track caused by rain. But we will do that as soon as possible. The build of this car was a pleasure and we are convinced that the new innovations in the 4.0 will result in better lap times and more fun.

We will drive this car and take a video of the first runs. Stay tuned at our Facebook page and we will share some footage soon!
