Technic Hummer H2
This is a very large Off-Roader, with the emphasis on functions, not performance.
About this creation
This is my first big, functional Off-Roader in ages, it seems, so I am glad to make this model. It isn't my most refined model, but it looks OK, and has interesting functions, and drives!
Aesthetics:
The model has a blocky body, like the real one does. There are opening doors, a swing-out spare tire, the rear liftgate, and a hood that I am ashamed to say opens the wrong way. (I discovered this late in the build process, and I was so short on grey (And just wanted to be done) that I left it that way) There is a simple interior, but with FIVE seats!






























Drive: There is 4WD with two XL motors. It could drive well in at least some gears.


Steering: A Servo motor steers the front wheels. That's as fancy as it is.



Winch:
There is a winch driven by a PF L motor through a 24:1 worm ratio. I used a little trick to be able to manually slide an axle through the 24T gear and out of the winch piece (Which allows axles to slide through it). This allowed me to pop the hood, slide the thingie, quickly extend the winch, then reconnect it and power it back in.







Adjustable suspension
On Wikipedia I learned that the H2 has an "Adjustable rear suspension". I didn't know whether that meant height-adjustable or hardness-adjustable. I went with height, using a PF M-motor, a worm drive, and small levers connected to the rear shocks. The height difference was minimal.










Suspension: There was front independent suspension, sprung using torsion bars (Like the real H2), and also rubber bands for extra stiffness. There was a rear live axle with two hard shocks. The front was longer travel than the rear. Wow. The pictures of the suspension are pitiful.









Gearbox:
There was a simple 4-speed sequential gearbox using the new Chiron shifters. It was shifted by an M-motor tucked in the front, driving some U-joints, which drove a stepper (Yes, that is a modified white knob wheel in the picture. In my defense, one of the knobs broke off naturally in the line of duty, so it isn't like I savagely mutilated a flawless element) There was a simple speed indicator. (Again, I gotta take more pictures. It also might not hurt to let the model survive at least 24 hours before I rip it to shreds and start on the next project. That way I could actually take MORE!)





Drive Mode Selector:
There is a fancy dancy drive mode selector that allows you to choose among 2WD High, 4WD High, 4WD Low, and 4WD Low all differentials Locked. This is controlled using a PF L-motor with a stepper. This stepper turns a longitudinal axle that controls the five variables. In each position it pushes an exact combination of variables, while the others are kept in their default position by rubber bands. I hope this makes sense.
















Overall, I think this was a cool model. I liked the drive mode thing, and the winch disconnect. It looked fine, drove decently, and was fun to make. The weight really hurt the performance. There is a video at: https://youtu.be/on_5oGaa5o4
