Tamiya Konghead 6×6 Monster Truck

Ever look at your RC collection and wish you had something a bit different than everything else? The Tamiya Konghead might be what you’re looking for.

This six-wheeled monster semi truck includes six chevron monster truck tires and a six-wheel transmission. The truck comes as a kit and requires assembly, but hey, building kits is fun. Let’s take a closer look at this unique monster truck.

As usual, the Tamiya box is well detailed with a top notch representation of the Konghead which is sitting inside.

The inside of the box is just as neat as the outside.  Everything is fitted just right and well packaged.

The majority of parts are located on parts trees. the manual tells you which tree you’ll find the needed parts on.

The tires will need to be mounted to the chrome plastic rims and the clear body will need to be painted. We’ll get into that more a bit later though.

The Konghead comes with a brushed motor, but no other electronics. The gears are extremely beefy and there are many of them.

The smaller parts and hardware are packaged into smaller bags, labelled for your convenience.

The manual is top notch with parts pictures listed on each page. The hardware images are life size, making it easy to match up the correct screws needed for each build step. the Konghead also comes with a high quality decal set.

The build is smooth and the parts go together well. As you can see in the above images, there are several gears lined up inside the chassis. The thickness of the gears should ensure their longevity. Tamiya also includes the necessary greases and thread lock to complete the build. Three gear differentials are used in the Konghead and the diff casing also doubles as the gear.

Plastic bushings are used to support the gears and brass oil bushings are used in key spots, where durability is needed..

The chassis has a built in motor mount which allows for two different pinion sizes. This means you don’t have to worry about setting gear mesh, just insert the motor with either the included 18 tooth pinion gear or a 20 tooth pinion and tighten it down. It’s that easy.

The suspension is pretty straightforward. The Konghead uses a lower H-Arm and a fixed length upper arm. While the suspension can’t be adjusted, it looks to be incredibly durable.

Dogbone axles are used at each wheel, which rotate on plastic bushings. While steel ball bearings are preferred, at least you don’t have to worry about the plastic bushings rusting if you hit a puddle.

The plastic friction dampers need to be assembled with the included piece of rubber tubing cut to length and placed inside each shock. As you can see, the suspension travel is greatly limited by the shocks, perhaps removing the rubber tubing from inside the shocks will help increase overall travel. For now, I’ll build it as the instructions state.

I mounted up a Ko-Propo steering servo to the chassis and installed the included servo saver. Steering geometry seems a bit weird, but it works completely fine.

The battery door is a neat design. It is simple yet effective. One side of the door locks into the chassis and the other side is secured with body clips. A piece of foam tape is used to keep the battery secure.

A plastic wheel hex fits over a steel pin. As you can see in the image, the wheel hex is fairly deep. The tires are mounted to the rims and do not include foams. The tire compression will help with traction and may add a bit of cushion to the ride as well. Once all six tire/wheels are secured with the locking wheel nuts, it’s time to get to work on the body.

Before breaking out the paint, it’s a good idea to trim the body and temporarily install all the plastic hardware. This will ensure a good fit before any painting is done. The instructions tell you what size to make each hole, and I used a Hudy body reemer to get the job done. The plastic smoke stacks and air filter canisters are really gonna make this body stand out.

After trimming the body with curved scissors, I sanded the edges for a clean finish.

Once satisfied with the way the body is trimmed, you must wash the body with liquid dish soap and warm water. This will clean off any of the oils left over from manufacturing, allowing the paint to stick.

Using blue masking tape, I taped off all areas that weren’t going to be painted blue. The kit includes masking films for the windows too.

I soaked the Tamiya paint cans in hot water to thin the paint, which made it easier to mix the paint by shaking. After laying down several light coats of Tamiya metallic blue (PS-16), I peeled the tape off all areas to be painted silver (PS-48). I sprayed several light coats of Tamiya silver and let it dry. I also used the silver to back the existing blue paint. This should make the blue pop a bit. The only color left to paint was Tamiya black (PS-5).

Once all the paint is dry, the window masks can be removed and the outer decals can be applied.

I tried to follow the decal placement instructions as closely as possible, but I decided to alter just a few things to give the truck my own touch.

The decals are excellent quality and once they’re on, there’s no removing them.


PERFORMANCE

The Konghead performed as expected. It wasn’t super fast, but had adequate speed for a fun time. Keep in mind here, the kit comes with a brushed motor, but that’s it for electronics. If I was looking for a fast truck, I’d throw a brushless system in it, plug up a LIPO battery, and let it rip. The beefy gears inside the chassis should be able to handle that added power, however, that’s not what I wanted from my Konghead. I was looking for an experience that was relaxing and fun, and that’s exactly what I got. I enjoyed watching the Konghead drive around, hitting an obstacle every now and then.

I found the large front bumper got in the way while trying to drive over large tree roots and rocks. It will however, come in handy when new drivers run straight into a block wall or something like that. Lol

The Konghead is unique. That’s what I like about it. It’s not super fast and it doesn’t handle like a race truck, but it’s unlike anything I’ve got, and that’s why I like it!

I built my 1st real RC vehicle in 1986 and have enjoyed this hobby ever since. I like all RCs, cars, trucks, boats, planes, helis, etc. I think every RC vehicle has its place, whether it be toy grade or hobby grade. They’re all fun to me, but the best part about this hobby is the people I’ve met and friendships I’ve made. But hey, enough about me. Share your background in the comment section of this article.
