Behold! The all-mighty, all-traversing Duck!

Jokes aside, this is a replica of a 1950's 4x4 light truck. Manufactured by the Czech company, Tatra, it was originally intended for military service use as an off-road transporter.

Over their production period, the trucks were mainly equipped with sided flatbeds, but were also fitted with radio equipment (as seen here), fuel cisterns, ambulance and even fire truck equipment.

Further uses after their manufacturing made their way into the private sector, with people and companies using them to traverse the woods, harsh snow, off-roading trials, and even road sweepers!

As for a powerplant, the 805 used Tatra's mainstream 8 cylinder, air cooled and gas-powered 603 engine. Does it have loads of power? Eh, not really (It was the 1950's, after all). But, thanks to its gearing, it had a top speed of about 83 km/h on dry pavement, but kept plenty of down-low torque and traction for offroad capability. Pair this with its 4+2 speed axle-mounted transmissions, (4wd needing to be engaged to access the +2), it's tall clearance, diff lock, and you have a serious offroad machine.

For suspension, the real life truck used a torsion-beam suspension (an early, early version of their famous "Backbone" system) making it quite stiff. Yet, it was still quite stable and comfortable enough for highway use. (The suspension system presented is a simplified version, as I am unaware as to how to make torsion beams work in SimplePlanes.)

The truck's cab was further used in Tatra prototypes, serving as a base for their passenger/delivery vans and low bed trucks (which didn't make it to production) using the 603 powertrain.

Inspiration to build this piece came from playing Snowrunner, as they had released this truck and the T813 as part of a paid dlc. That, and I was bored one day and just started thinking about it's unique suspension and drive axle system.

Lastly, I present to you two extra trucks, free o' charge.

This current page holds the radio operations upfit, while the two links below take you to a the version with the bed as shown, and an empty frame version for you to build your own off of.

The steering mechanism in-game is slightly different on the bed truck, as an experimental and slightly less reliable yet more realistic steering box is used. Additionally, a low-part count version could be pushed, if requested.

Anyways, here's some screenshots and the controls to pique your interest.

Pitch and Yaw - main driving controls
VTOL - Open front windows
Ag1+2 - lights
Ag5 - self-righting
Ag6 - Open Doors
Ag7 - 4WD

As for VR users, all control equipment is labeled inside the near-fully recreated interior. As usual, pressing the trigger on any controller will activate the brakes.

Forgive me if any of the interior controls are wrong, I struggled to find a decent video or diagram of their uses and I don't exactly own one in real life to find out.
