[MOC] 1:10 Land Rover Defender 110 RC (42110 Mod)

[burak]

Hi Eurobricks,

I proudly present to you my first MOC. A Land Rover Defender 110 with RC functions.

This is an original MOC, which was built from the ground up and has very little in common with the official 42110 set from 2019, except for ~64% of shared parts. To start with, unlike set 42110, this is the 110 version with a longer wheelbase and true to scale proportions in 1:10 scale, which were derived from the original car’s blueprints. To accommodate this the chassis and bodywork have been completely rebuilt with realistic proportions and the iconic details of the original in mind.

 

Specifications:

• L x W x H: 50cm x 22cm x 22cm (with accessories)
• Weight: 2925g
• Parts: 2853
• Scale: 1:10
• 6 motors
• ~5m of electric wires
• ~3m of pneumatic hoses

 

The model features full remote control of many advanced functions:

• All-wheel drive through 3 differentials powered by 2x BuWizz Motor and 2x BuWizz 2.0

• Steering with Ackermann geometry and working steering wheel
• Signature front and rear LED lights
• Center, front and rear differential lockers with 4 locking modes
  • None locked
  • Center locked
  • Front & rear locked
  • Center, front & rear locked

• Adjustable air suspension
  • Variable adjustment of ground clearance from 22mm / 2,75 studs in standard mode up to 32mm / 4 studs in off-road mode
  • Infinitely variable adjustment of pressure for optimal suspension stiffness
  • Realistic approach, breakover and departure angles (standard mode & off-road mode)
    • Approach angle: 35° standard & 42° off-road (real: 30,1° standard & 37,6° off-road)
    • Breakover angle: 18° standard & 28° off-road (real: 22° standard & 27,9° off-road)
    • Departure angle: 33° standard & 41° off-road (real: 37,7° standard & 41,9° off-road)

• Auto-compressor powering the differential lockers and air suspension
  • Automatically shuts off at a system pressure of >2.1 bar / 30 psi and restarts at <0.9 bar / 14 psi

• Additional auxiliary PF output accessible from engine compartment

 

 

Those „guts“ stay mostly hidden and the model features a detailed and spacious interior with further manual functions:

• Working door locks on all 5 doors
• Manual system pressure release valve below the dashboard
• Adjustable and foldable front seats and completely foldable 2nd row
• Spacious loadspace
• Small details such as air vents, climate controls, storage compartments in all 4 passenger doors and between the front seats

 

 

Additional features:

• Easily detachable roof panel
• Front and rear independent double-wishbone suspension with camber angle providing 44mm / 5,5 studs of travel per wheel
• Partly modular bodywork, which is attached to a rigid monocoque chassis. The model is therefore very sturdy and can unhesitatingly be picked up by the roof
• The suspension setup accommodates easy interchange of the wheel hubs
  • I’ve fitted hubs with planetary gear reduction as standard, because they enable superb off-road capability
  • Those hubs can easily be switched out for hubs without planetary gear reduction (from set 42160) to enable higher top speed. However I did find that the BuWizz 2.0 units quickly run into power cutouts when you’re not easy on the throttle. If there was a juicier power source I can image how much fun driving with those hubs would be

 

 

You have surely noticed that there is a few random colors in less visible parts of the model. This is due to the model being optimized to use as many parts of set 42110 as possible (~64%), because I’ve created instructions for it.

Here’s a video showcasing the main functions and the model in action:

 

 

You can find a few more pictures on my bricksafe here or check out the instructions on rebrickable here

I’d be happy to hear your feedback!

If anyone is interested I can also share some background on the development and a few tricks of the model some time

Nice model, I watched the video and it just got better and better. 3 diff locks, pneumatic suspension, full interior, I'm impressed. Are the gearbox driving rings on your cv joints there to act as a smaller version of the long cv joint in the zetros? Also, could we see a photo of the underside of the model?

[Paul B Technic]

Wow, this is amazing. The more I read, the better it sounds. You have packed in a huge number of features.

[StudWorks]

Amazing! You should consider posting the instructions on Rebrickable.

 Incredible model. Fantastic mix of looks, features and rigidity. Technic doesn’t get better than this

 

[HorcikDesigns]

Hats off, this is piece of some serious engineering and skill. Good job!
I add to the group calling for chassis pictures with emphasis to the drivetrain (especially area behind the motors) and axles.

Nice job! It's quite interesting to see a complete rebuild of an official set's premise-same scale, same color, but with MOC-level functionality. Very nice!

Thank you! Exactly, because the upper and lower wishbones on all 4 wheels are not parallel there is a slight longitudinal movement of the CV-joints between the highest and lowest suspension setting. The driving ring holds the joints together loosely but securely, while allowing a slight longitudinal movement. You can find a pic of the underside of the model below

Thanks! Already working on it..

Thank you! It's nice to have some kind of a baseline to start with, even though there is not much left of the official set after all this time

Thank you very much! It's pretty simple actually: The motors drive the newish-type 28-tooth central differential through 20-tooth gears. The differential outputs go straight to the front and rear axle differentials. I believe you can see the most part of the drivetrain in the drivetrain render in my post. Here's a better resolution version:

 

And here's a pic of the underside:

Amazing! I prefer your clean interior over the original one. Finally we can have passengers with legs using the back seats.

What about heat/cooling of the Buggy-Motors?

Really liked the way you implemented the looking glass for this MOC. Five years (almost) gone and it feels amazing how this set still keeps getting such awesome creations ❤️‍🔥

Thank you! 

The motors get pretty warm when putting them under high load constantly, such as when I drove up the hill in the later part of the video. Btw I've measured that slope at around 35° in the steepest sections. So far I haven't had any issues with overheating or power cutouts thanks to the combination of planetary wheel hubs and BuWizz 2.0 in normal mode. When using ludicrous mode or wheel hubs without planetary gear reduction, power cutouts can occur when accelerating too fast or putting the model under high load for a continuous amount of time.

Thank you! Since then I restarted the project multiple times, because there was constantly new parts available. It was quite interesting to see how Technic in general has progressed throughout the years.

What a terrific model.  TY for sharing.  I also enjoyed the video and how you illustrated the functionality.  Not only in nature, but also on the dyno-meter like contraption you made.  Extremely well done.  

Wonder if the new G500 could ever become something like this. Also would be interested if the wheels from the G500 would fit on this.  Prob. not on suspension low setting, but def. on high suspension mode.

Thank you very much for your feedback! I thought of ways to show off the different diff locking modes and their effects and this seemed like the best option. To make the effects visible the dyno had to provide different rolling resistances on each wheel, so there is a few different gear ratios going on.

I'm actually pretty excited about the G500, it would make an interesting project for sure. If I get my hands on it this is something I will definitely try out!

[burak]

So I got the G500 and before building it I had to try the new tires on the Defender (as requested by @nerdsforprez  ).

They fit without problems, there is no rubbing when steering or raising and lowering the air suspension and wheel articulation is still as great as it was with the stock tires.

Here's a few quick pictures I took, what do you think?

[2GodBDGlory]

Very nice! That thing looks like it means business now!

[Paul B Technic]

That looks much better.
