The only thing really extreme here is the price.........

[@jacekpietrzak445]

Audi is quite cheap for a Technic RC car but X-Treme Off roader is really expensive. It is 2 or even 3 times more expensive than Audi.

[@Viper69X]

​@@jacekpietrzak445i paid £200 for zetros mercedes

[@operaatio5117]

Turn the audi into a cursed crawler. Live axles on both ends, transfercase with diff lock and hi-low gears and lockers on both rear and front :D

[@mkprofessionalism]

The Audi one of the single greatest Lego Technic RC car of all time. Nice look,advenced building techniques here and there,new parts and recoloured useful parts.

[@Sauci55on]

I would say it’s the best among the recent ones, but I think the old buggy’s that introduced the buggy motors and RC units might have been better

[@Void_s]

Yeah, and with BuWizz it runs like "go-go to Hell", such a crazy light-weighted overpowered thing

[@cloudyfer7667]

It's also surprisingly cheap and basically an ultimate lego car tutorial

[@liamaston6545]

Great Video Balazs, very informative as to the pros and cons of each set. The level of dedication to grow the grass the right length for the off-road challenge is superb!👍

[@RacingBrick]

Making everything for the viewers ;)

[@octoslut]

Excellent video as always 😊

[@coffeeinhandproductions3238]

This was really cool to see. You can definitely get a lot more speed out of the Audi as already shown in the vid. But it could probably go even faster so my vote is for more speed.

[@carsonkalinowski]

Hi amazing editing keep up the good work!

[@jthairy]

Your hobbies are an inspiration, man! You must feel very blessed

[@ericoberle9794]

Cannot wait to watch you build the concorde

[@a_bad_channel]

these are great quality lego videos. you should have more subscribers

[@Shorjok]

Nice video Balasz, to be honest I'd like to see more of that crawler course, it looks sick. Try putting a couple of buggy motors in the Audi [or buwizz BMs] and see how well it performs on a hard sand [like at the beach]. It's obviously not designed to be an offroad monster, but the speed by default does disappoint, that's my only gripe with the set. Lego should really be doing better with their RC vehicles these days.

[@L2SFBC]

Great video, came here looking for drivetrain explanations and found it, confirming the Audi is twin-motor. A couple of notes; the taller tyres on the Offroader would help it on the grass due to greater ground clearance which means less vegetation drag, and also better obstacle clearance. You can also increase torque by reducing the wheel diameter and width on the Offroader. You want the tallest possible wheels offroad, generally, but there's no point if there isn't the torque to turn them. If you could link the front and rear axles mechanically, and have both motors turn that driveshaft, then the vehicle's total torque would be better directed to where it needs to be. Going to get an Audi now!

[@BatteryPoweredBricks]

Nice crawler course!

[@M0torsagmannen]

differential lock would help a lot, would like to see that first

[@ivansmith654]

I get the feeling that Lego vehicle are not made very well to be RC vehicles; fun to build, and look at! Just my opinion!

[@Felix-gv3su]

Thanks for the cool Video, could you try to close the differentials and try again?

[@MikeTwo9398]

Nice video (as alway) informative and to the point. At about 3:38 you tell that there is no big difference in torque between the differentials but I would like to see the differences. The differential with the red gear (ratio 12 to 28) should show at least more torque then the differential with the yellow gears (ratio 14 to 22). It will be about 1/3 slower but it might climb better.

[@jeremykhuu]

Amazing video, but I would love to see the audi with the buwizz motors compared to stock

[@a_bad_channel]

nice crawler course

[@nanocodethespectator2646]

Hmm... how about increasing ground clearance for the Audi and replacing the old planetary hub with the ones in the Audi for the Xtreme Off-Roader?

[@RacingBrick]

If I replace the hubs in 42099 with the new ones than I'd need to gear down the outputs heavily to have any reasonable torque.

[@riaandutoit11]

Looking at the electronics, powering the Lego Powered Up Technic hub with more than 10.5V could permanently damage the motor driver ICs (LB1836). The operating range of the LB1836 is stated as up to 9V with an absolute maximum of 10.5V. The voltage from the battery pack seems to go directly to the motor driver but is regulated for the other electronics (the absolute max of the regulator is 17V)

[@Hernanchi]

I think that te next upgrade that the both sets need, is a locked differential.

[@shroomzzz]

A locked rear in the audi should significantly improve it's off road capability with minimal impact on turning. Of course, you could build the Buwizz variant and throw it in there for comparisom.

[@aconcaguaushuaiamachupicch2518]

You could try different kinds of wheels and tyres on Audi. Also maybe there is a way to change ground clearance on Audi also. Maybe see different types of differetials, hubs and how would it behave if both axles would have locked differetials.

[@GundersenMarius]

It would be cool if these rc cars had a gearbox which could change from high speed to high torque and lock/unlock the differential. Probably too much of a modification for this set though.

[@BrickMania-BG]

More torque is better. ;) Nice video!

[@Steveogorek]

What about locking diffs in audi first? (With buwizz power?) how it performs on speed cornerns without diffs? Maybe even slightly different gear ratio between front and rear so it will drift a bit? :) Then swap for hubs with gearing should be easy too?

[@simonmills2250]

I need to get the Crawler, it's very cool. Got the Audi and it's OK but I prefer the TG Rally Car. If it was me, I'd be looking to get the Crawler more able to climb steep gradients

[@UrMomsChauffer]

I would like to see the Audi with more ground clearance and speed.

[@patrickfearon7942]

What is the new power you added to make it faster?

[@Espen_Danielsen]

I would like to see buwizz motors for both sets tested bot for speed and crawling power!

[@GalacticBricks2024]

@racingbrick you should make the Audi RS Q e-tron a rock crawler by giving it clearence, suspension ect

[@_Pikalika_]

Would love to see the RSQ goes faster

[@Viper69X]

how about try to still use the red heavy duty hubs as well as the planetary gears and if you want to get rid of the diffs then you will need to just put a regular 28 tooth gear and a slightly longer axle

[@brendan_creator]

hey racing brick if you could please tell me what brand is the batteries are you using for the 12v version?

[@RacingBrick]

Those are not batteries but BuWizz 3.0 Pro units, you can find more information on buwizz.com

[@brendan_creator]

@@RacingBrickok thanks

[@julianvandertoorn8342]

Do you have the lego concorde for review

[@iamjayrobinson]

A much higher ground clearance, and maybe larger wheels too, on the Audi - Trophy truck style, would be awesome. With maybe more speed too?

[@brendan_creator]

3:14 ive got an idea, what about we use 2 of the large motors to support a solid axle that connects the front and rear wheels by using 2 20 tooth gear on the 2 motors and on the solid axle we could use a 12 tooth gear.

[@ashwinaydansanjay1658]

hi Balasz i am 11 years old and since i love speed and off road, i thnk you should get the hubs seperately and add more hubs to the Audi. i live in malaysia so the price is quite high. which hub is the most powerful and fastest hub mixed?

[@stratophere0079]

Is there a way for you to connect both front and rear motors with a center diff locker for the audi to improve torture?

[@RacingBrick]

As the front motor is in the way there's no easy method to do this, the whole setup should be rearranged for that.

[@soundwave2098]

Bought the Audi like 5 minutes ago then this video popped up on my recommended and I giggled a bit at the coincidence.

[@mystero233]

Sorry I didn't get it from the video. What did you change to get higher speed? What power unit?

[@RacingBrick]

Buwizz unit

[@AKV119]

I hope someone can make a video of making the Audi a crawler because I took mine apart and bought gears but it is impossible to change gearing so now I have many pieces just on my floor.

[@rickretro4687]

Can You make a video e-Tron vs 42124

[@bournejsn]

The dakkar needs suspension with more throw and perhaps more powerful (moc/cada) motors, and the crawler needs locked diffs and aftermarket motors also for higher torque.

[@TheDethsight]

sadly, my audi always veers to the right a bit. tried recalibrating it a few times to no avail. i really don't want to take it apart though lol.

[@nanocodethespectator2646]

Maybe try taking a close inspection of the drive train? I don't have the set but I feel like that would be the most reasonable solution

[@gamingnoname_2718]

Balasz, what motor did you use to make the Audi and the 4x4 faster?

[@RacingBrick]

It was not the motor here, the Technic hub was replaced with a BuWizz 3.0 pro unit to give the motors more power

[@gamingnoname_2718]

Ok

[@drscre]

Two speed remotely controlled gearbox please

[@user-rw1ox3lp9f]

Can you make the Audi faster for the next video?

[@brendan_creator]

well i think for 42160 would look better with a faster gearing because the real thing is for desserts not climbing so if possible i would mod it to make it faster

[@McChicken1087]

Would love to see the Mercedes comp truck do the crawler course

[@RacingBrick]

That one suffers from low ground clearance unfortunately

[@radbot1]

Can you swap the Audi's 1:1 hubs with the off roaders 5.5:1 hubs?

[@RacingBrick]

Needs a little tinkering but it is certainly possible.

[@doytr2226]

speed speed n more speed :)

[@sypialnia_studio]

Make it faaaaasteeeer!!!

[@spartan-5795]

the Audi feels like it deserves a speed upgrade, but i really wanna see it have better crawling ability. Torque.

[@Nachitolv]

Plss try mercedes 6x6

[@levyroth]

For the Audi: bigger tyres, more power, more speed!

[@vladyslav_andreiev]

Lock differentials

[@laserturkey-tz8pt]

Speed her up!

[@IamSaud_YT]

It would be better if you also tested them in sand and slight mud conditions. After all that Audi is supposed to be a Dakar racer, not a rock crawler.

[@RacingBrick]

You can already see the speed and performance on road and in grass, sand and mud would be expectedly worse. And I won't put my LEGO vehicles in mud, sorry, don't have the time and patience to take it fully apart afterwards to clean it.

[@IamSaud_YT]

@@RacingBrick hey, thanks for replying. All I mean to say, is the test seems unfair to me. One is a sand racer and the other one is a rock crawler. Putting them into the same testing field is not a good idea. But anyways keep up the good work!

[@RacingBrick]

@@IamSaud_YT LEGO has a pretty limited range of RC vehicles, there's practically nothing in the same league. Lot of people had 42099 so I used that as a reference, as I mentioned in the video this is not a comparison or competition, simply showing the performance of these vehicles.

[@IamSaud_YT]

@@RacingBrick aah, got your point. So basically you used the Rock crawler as a reference to test the Audi. Sorry, I didn't get that first, I watched the entire video tho and the mod in the end really buffed the Audi. ✌🏻

[@allanallan4791]

Dakar Audi for speed and use the other as a crawler. All tech sets need to be motorized

[@hellraiser666666]

audi speed!

[@roborbob2913]

These motors dont seem as powerful as the old poer functions motors 🤔

[@Isimus]

Better crawler!

[@leonthomas8377]

You need a buggy motor

[@RacingBrick]

Only one? :D

[@rexrapid]

More capable crawler

[@TundeEszlari]

You are a very good KZbinr, can I get a comment heart?

[@deltazero3796]

DISAPPOINTMENT

[@dawiddawid835]

Żałosne są te napędy w lego

[@habich9072]

Diese Vergleich ist wie ein Fiat 500 und ein Porsche absoluter Bullshit !!!!

[@SgtSalt-rx3hb]

Extremely poor performance by both Models😱 shocking!!

[@MISTER_FORRO997]

the xtreem off roader needs a bit more tourqe and speed

[@MISTER_FORRO997]

more speed for audii
