[MOC] RC Off-roader With SBrick

Recommended Posts

Like I said in my last topic, I’m a big fan of Japanese cars.

Today I’m bringing you a new MOC based on a popular off-roader.

Inspiration & Goals

This MOC was inspired by the Toyota Land Cruiser Prado series.

I didn’t want to make an exact copy of the original car, but focused on the chassis and drivetrain.

Also it should have a full-length body with five openable doors.

Compromises & Inperfections

1. The model has about 2700 parts. Given the functions that I achieved, that’s a huge number. I was expecting it to be around 2000.

2. It is WIDE. Even with those beveled window frames it looks wide.

(It is wide. The body covers the whole tyres from top view)

3. Gear ratios are 5:1 at 1st gear and 5:3 at 2nd gear(differentials not included). Safety fuse kicks in quite often when steering at full speed on 2nd gear(As shown at the end of the video).

I have to use 9V AA battery pack instead of Li-Po and stick to 1st gear most of the time.

4. A real Land Cruiser Prado has central differential & central diff lock. They were on my prototype. Rear diff lock and central diff lock work simultaneously.

But they are quite unreliable. 12-teeth half bevel gears inside the central diff got damaged after only a very short period of test drive. I have no choice but to remove them from the drivetrain.

A short video showing the prototype:

Anyway, I’m basically satisfied with the overall performance and looking. Building instructions will be ready in a while.

Hope you enjoy!

For me the roof is a bit off, could be 1 stud lower. But other than that, I can just say, it is amazing. Again. :thumbup: :thumbup:

Love the front :wub: , the rear, the drivetrain, and the video (+ points earned not to edit out the cute end :classic: )!

Thanks :wink:

I do prefer a lower body, but the body is already too wide, and I was planning to make it even more higher to compensate the width. :grin:

Stunning! I'm hard pressed to decide what is it that I find most impressive, body work or chassis... pure awesome!

Can't wait for the instructions :)

A brief update on building instructions:

Chassis is complete, around 1300 parts, right about half way done of photo shooting. But post editing work takes much more time, I’m assuming two more weeks at least.

  Sorry for the late, building instructions available now.

It is basically the same style as my previous BIs, but with some minor improvement, like red arrow with white outline.

Another feature: multiple steps with separated parts list in one page.

This feature involves a photo editing technique of cutting an object out of its background. It’s not a high end technique, but the process is very time consuming.

 

It’s now on Rebrickable: http://rebrickable.com/mocs/musenkevin/lego-technic-rc-off-roader-with-sbrick

 

Hope you like it :classic:
