Hello everyone!

Im glad to introduce a new RC MOC that I build! It is not a 100 replica of Jeep Wrangler, but I was inspired by it while building the bodywork.

The instruction could be found here:

https://rebrickable.com/mocs/MOC-93754/danil.nig/jeep-wrangler-rc/#details

 

Features:

 - Universal chassis

 - Live axle 4-link suspension

 - 4 wheel drive

 - 4x PF L-motors for propulsion (2 for each axle)

 - PF Servo motor (or PU L-motor) for steering

 - Ackerman steering geometry (not that essential for off-roader  )

 - Buwizz 2.0 (Buwizz 3.0) for power

 - 1.5 kg of total mass, well-balanced

 - admit a trial mod with planetary hubs and 4-wheel steering!

 - >90% of parts are taken from 42110 set (except motors, new joints and few more pieces...)

I have to mention, that the front of the car was taken from gyenesvi`s MOC. But I made it 2 studs wider and use my own mounting system to connect it to the custom chassis.

Here is the chassis of my car

After taking the previous photo, I made a new body for it!

 

Here is an official video!

 

Hope you like it!

Looks very good , does it drive well? With BuWizz it should have much power. I just can't recognise the tyres, are they non-Lego RC tyres (if yes, the performance may be even better)? A video would be nice.

Glad to see that my model inspires others! Nice build, the general shape looks good, although I have to admit that it feels a bit unfinished. But I guess you were not going for the looks but the functionality and keeping the weight down. I like the chassis, the suspension with those long shock absorbers should be much easier to build and make it smooth and largely articulated (it reminds me that I should start doing more non-alternate builds). Those tires also look good on it, what are they? I guess some custom RC tires, something like 85mm ones?

I have seen a video of this in your long review post in the Zetros mod thread (maybe would have been better placed in the original Zetros thread to get to the right audience, but I'll admit that I have to agree with some points you made there). Anyway, it seemed to drive quite well, you should post that video here as well.

Thank you for your big and useful comment. Im not good enough at bodywork as you might understand, and yes, I place the drive experience as a top priority, so some decorative parts are missing ;-) (in order to lower the weight...) But I believe, that a PRO builder would get all thous details without adding extra weight!

I have posted my MOC at Rebricable, but does not pass the checking yet. So the link for PDF instruction will be available soon. The Rebricable version will have 7L shocks in front (to make the car lower, stock version), but the bridges are easily customizable. If i would tell you a full story of the build, i started not with the body but with chassis. And the general idea for the chassis was inspired by Attika`s Pickup X: 

But after some time i changed it a lot... Add 2 more L-motors. I REALLY like the idea of Live axles... it totally changes portal hubs!.. But to build it you need to modify several parts!

Benefits:

 - high ground clearance

 - no stress on the transmission

 - good scrab-radius (that is 3 times better than with portal hubs)

Here is this crazy trial version:

I think, it is possible to obtain even better articulation by moving the mountain points of strings closer to center. The double soft strings are very appreciated to handle this body (hard 9.5L strings are too much).

 

Also, I will make another video with the car that is build bu Rebricable instruction... But it will take me sone time ;-) 

 

P.S. Wrangler has 90 mm RC tires and purple pickup (I will speak of it later) has 85 mm RC tires... Hope Lego will come up with this tires some time case they bring a lot of realism to the cars...

 

P.P.S. Cant wait for your RC MOCS, gyenesvi!

Man that looks awesome! I'd love to build that chassis and make a tubular frame crawler out of it.

Thank you for your comment! I have 3 videos for now, but they are showcasing the TRIAL MOD of the car (with portal hubs), so the stock version drives 5,5 times faster and thus has a lot lesser torque... I will make a video with a fast version later. And for now:

 

Here are two trial competitions I made! Sorry for the video quality, I have zero skills in them. Also in the last two videos i was playing a role of a driver and operator of the same time...

 

Zetros has a lot of problems with geometrical pass-ability, while 9398 perform really well with small changes: 1:3 ratio in hubs and Xserion tires.

 

Does it drive well? In is not a fast car for flat surfaces, so it is boring to drive by roads, but it has very good for trial! Since the car has 4x L-motors for propulsion (twice as much as common lego set) and a total mass of 1.5 kg, it perform really well! Actually, it has more torque than the Zetros set!

 

If you want to see a faster version now, my purple pickup (i will make a post on it later) has an off-road setup (with new differential instead of old one) 

So the stock model will go even faster than the purple pickup!

By the way, the off-road version pass all the trial tests except "high stair test", and due to my research it very close (in torque) to the 9398 set, but 3 time faster!

Thank you! Hope to see your version. I think it will be a lot lighter! (about 1,1-1,2 kg)

If you can PM me instructions for the chassis only, i'll see what i can do!

Im glad to announce, that the instruction is available here:

Hello everyone! Wana see a real driving test? Here it is:

As you cam see, 4 L-motors can really make these cars drive!

Jeep Wrangler has 90 mm RC tires while the Puirple Pickup 85 soft RC tires. The difference in resin is visible in snow: soft resin was always covered with snow... But it will work for summer rock-crawling I suppose!
