[MOC] Vintage Monster Truck - instruction available

Recommended Posts

Hello everyone.

As a monster truck MOC was one of my earliest creations, the time has come to remake it!

800x450.jpg

Weight: 2030g

 - Powered by 2 SBricks

 - 4 XL motors for propulsion

 - 2 Servo motor for steering

 - M motor for switching steering mode (normal/crab)

 - M motor for raising front hood and rear bed

 - LED lights for headlights

 - Openable doors and tailgate

Those old-school power functions components still work sufficiently in this MOC.

The body was inspired by 80's monster trucks made from lifted and modified Ford pickup trucks.

The under structure was designed for robustness. Eventually it looks more like modern tubular chassis.
There could be multiple options for the sets of dual shocks. (Hard/Soft, Hard only, H/H, S/S)

Vertically placed M motor moves Polarity Switch connected to rear Servo motor.
Horizontally placed M motor is for two functions. Front hood opens via worm and 24T gear. On the other hand rear bed is raised via small actuator. That requires two driven axles of different torque and rotational speed for each side. Center differential enables single motor to transmit the power to both sides.

One of the benefits of portal hub is easy to change gear ratio.

Body parts could be replaced with different color scheme, though they are not fully modular.

On November 2nd and 3rd, Monster Jam live was held in Japan for the second time. I did go to the event and took photos of amazing real monster trucks and drivers.

Thank you, Bari Musawwir and Neil Elliott!

I love the classic look of the body! Many clever solutions under the hood as well - especially using the differencial to run two separate functions. I am surprised that swivelling gear rack for steering works! Was it really necessary to use so many shock absorbers? I guess the body was to shaky if not...

Under fine work of engineering! Congratulations.

Best regards,

Thank you for watching! I wanted to use dual shocks only because its look. As the black version does, using single hard shock for each wheel is enough to hold the body. But dual soft shocks was a little bit unstable.

This is just too cool! You nailed the classic look. Just how I imagined it when reading the thread title and then some. Would realy like to build this. Now, where did I put those shock absorbers from the 8880...

a few designs remind me to old tamiya Models like Clod Buster and Blackfoot. Love it.

Such a beauty! Love that boxy look of it. There's no shortage of power with 4 XL motors, I suppose?:sweet:

The blue one with dual wheel looks epic! Will definitely build one once your instruction is done, great work!

Wow, really cools MOCs. Who cares about 41999 when you can build this! I foresee an instant drop of the rip off prices on eBay. :tongue:

Thank you as always for providing instructions. Much appreciated!

Last night I visited the studio of my friend rm8. We made a review of my Monster Truck!

Now we arrived Moscow and will join the event of Russian Technic fans.

Instruction will be available after coming back to Japan.
