I own a boring station wagon, so I guess this is what I wish I was driving. I don’t live in a war zone, but it would be perfect for someone who does and still wants to drive in style. This is my first big MOC, so I welcome praise and criticism alike. After all, that is how we improve.
About this creation
Functions
- All Wheel Drive *
- Steering *
- 4 Speed Transmission *
- Concealed Turret (Elevates and Rotates) *
- Opening Hood
- Sliding Canopy
- Independent Suspension
- Pistons

*Remote control functions


Exterior

I knew it was going to be a wagon, but other than that I had no preconceived plans for how it would look. I just started putting pieces together, and the shapes that I thought were interesting ended up on the vehicle. Overall, I really like the end result. It will probably not appeal to everybody, but that is true for many of the best designs.

Dimensions:
Lenth = 64 studs
Width = 29 studs
Height = 18 studs











I want to take a moment and give praise to Lego for all the body panel parts. With a bit of experimentation they can be used to make some really cool shapes.












They are a bit difficult to see, but the tail pipes match the triangular headlight arrangement. It was easier to see with grey tail pipes, but it was an awkward contrast, so I went with black. I may still make changes to the rear section of body work. Come to Bricks Cascade and you will see the result.





Turret

Concealed in the back is a turret for dealing with threats, or for sadistic owners, to deal with traffic jams, tailgaters and oblivious drivers loitering in the passing lane. I promise I’m not sadistic.

Elevation is achieved with a scissor lift combined with a small linear actuator and M-motor. A separate M-motor and turntable are used to rotate it 360 degrees. Rotation is limited by the length of the motor wire. Both are remote controlled.











With the turret lifted up, you can see the scissor lift, IR receivers, and parts of the transmission underneath all that.






Interior

There are no doors. Instead there is a “canopy” that slides open. This could probably be motorized, but I ran out of IR receivers to control it.





Most of the interior is easier to see with the canopy removed.








Engine Bay

The hood opens from the side to reveal a V6 engine with working pistons.








Steering

Steering is controlled remotely but the steering wheel still works. I used a power functions servo motor, which is hidden underneath the center of dash.




Undercarriage

The frame is loosely based on Sheepo's modular system.




Drivetrain

An XL motor sends power through a remote controlled 4-speed transmission, to a center differential for all wheel drive. The “circular” path that the drivetrain takes between the motor and center diff may seem weird, but turned out be an efficient use of vertical space.

All wheel drive was a bit of a challenge. It might have been easier to use the old style differential in the center, but I didn’t own one at the time, and it would take too much effort to redo it now.

The transmission is based on Sariel’s 4-Speed Compact Linear Gearbox. I wanted at least 4 speeds, remote control, and I did not want the gearbox dominate the available space. All of the axles in the gearbox are mounted only 3 studs above the drive axle, which was crucial to allow room for the turret and rear suspension and still maintain a low profile appearance.

Two L-motors are used to push the gear cassettes back and forth. I needed to shift gears rapidly and it takes a strong motor to do that when the gears are spinning fast and under load. It was definitely a challenge to prevent backlash in the motors from causing it to shift out of gear, but the solution I came up with was successful. Unfortunately, it is buried deep in the car. I will need to disassemble the car nearly to the frame in order to get pictures of it. When I recycle this thing in a few months (probably after Bricks Cascade), I plan on posting some pictures of it. Sorry for being ambiguous here.

If I did it over again, I would try to make the gear ratios closer together, and constrain some components of the drivetrain better. As it stands, there is too much flex in the drivetrain to cope with the torque. Gears occasionally slip in 3rd gear, and 4th is pretty much unusable unless the wheels are off the ground. As a result, this is a better demonstration of technical possibilities than driving performance.






Remote Control

I used 3 remote control units. This could be reduced to 2 if I control the transmission and turret from a single unit and switch IR channels.

Very impressive!!! One of the reasons for me not to build with stud less Technic is that I don't want models to be transparent. A model you can look through for me is not expectable! You on the other hand managed to build a model that is "closed"…well done my friend!!!

This is brilliant, wish this could be a set, but I would be afraid of the price. Still, crazy awesome design.

This is a truely magnificent build. I like everything about it. The color, gadgets and gizmos. You can probably tell I'm not a car person. Since I live in the 3 1 3 and must drive through the 'D', I could really use a car like that. I especially like the turret. I could blast my way through town.

Simply brilliant. You've utilized the panel pieces and other Technic parts to create a very smooth exterior, much better than most any actual set. The shape and detail of the vehicle itself is very attractive, and the gun turret is just plain cool. IMO, you should send this to CUUSOO, I'd love to see it as an actual set.

Great imaginative design and RC gadgetry! But wait… no exterior wrap-around digital sign strip that would display your verbiage assault on some wayward motorist! Ha, ha! :)

It's a Vista Cruiser on steroids! Holy cow is that impressive. The hidden turret should be a standard feature on any vehicle meant for highway use. Fantastic features with a decked out interior as well. The dash is fantastic. Excellent work!

"I don’t live in a war zone, but it would be perfect for someone who does and still wants to drive in style" I imagine a commercial for this in Robocop style where the announcer goes "Someone took your parking spot? Fear NO MORE" followed by a sequence where the rocket launcher is used to create some space. Sooo many functions!

that thing looks like a right brute. i love the details, and the fact that it's technic and there's no panel gaps that i could easily fit my two cats through. amazing job, looks great!

Quoting Senator Chinchilla . You had me at "Drivers loitering in the passing lane". This is a great concept! Just a whole neatly built bundle of lunacy. All the paneling is great, and those headlights are super unique.
