The video was recorded at the end of September 2023. It is a 1/11 scale model of the Czechoslovak Tatra 813 Kolos 8x8 truck (although the manufacturer of the model declares a 1/12 scale). The model was built from the Cross RC DC8 kit, which I bought in the Belgian MCM Racing shop:www.mcmracing....
Including all the breaks, and there were a lot of them, it took me about 8 months to assemble the model.
The inspiration for such painting of the model was a photo of a real truck from the article: www.nztrucking...
Tara trucks have a characteristic structure - a central load carrying backbone tube, independent swinging half-axles. They had been produced since 1967 to 1982. The Tatra 813 can tow trailers with a total weight of up to 100 tons. A noticeable characteristic of Tatra trucks is also the fact that the wheels of the unladen vehicle are arranged in the shape of the letter "V".
I also put on the model elements that are not available in the kit from the Cross RC manufacturer: winch, reversing light, front marker lights, three additional headlights in the front (one on the roof, two under the front windows), two warning lights on the roof, I added the rear direction indicators in half of the rear lamps.
Of course, I also modified the electrics, among other things, I separated the main headlights of the model into separately activated low beam and high beam. My wiring diagram is available at the link: drive.google.c...
The original front suspension seemed too firm to me, so I replaced the springs of the auxiliary telescopic shock absorbers.
