Comparing the gearing upgrade options of the LEGO Technic 42099 4X4 X-treme Off-Roader

The LEGO Technic 42099 4X4 X-treme Off-Roader is a great set and it offers a relatively easy way to change the internal gearing, allowing us to find the balance between speed and climbing abilities.
Last year I published 2 upgrade options, now I compare them with the original directly to show you what are the differences.

Stage 2 upgrade - • LEGO Technic 42099 4X4...

42099 could definitely use a gearbox, would be cool if it was also remote controlled or automatic.

[@handsomejack4947]

Yeah but every gear between the wheels and the motor reduces its power.

[@KennyMinigun]

@@handsomejack4947 But still, a gearbox would make 42099 overall faster and more capable on an off-road course

[@Brato1986]

@@handsomejack4947 Does silicon grease help on the lego wheels ? Would be nice to have bearings for lego.

[@handsomejack4947]

Brato not sure, graphite powder helps but can hinder the gears performance if it gets in them

[@Bmr4life]

@@handsomejack4947 Not by a significant amount.

[@MrDorino]

Great video, like always! Will you release instruction to build 42099 with Power Functions motors? Thanks

[@RacingBrick]

I will when I get my mod back, it's still in the warehouse

[@clevmagyk770]

wow, your grass must require a lot of effort to keep mowed and green-looking! seriously though, amazing video, great to see how the two different modes compare.

[@defaultdaniel]

Hey so I discovered that with Buwizz I have less power cuts than vs. Technic Control. I tested each on the same obstacle course (this exact set 40299) and where Technic Control would cut power earlier or give up on a certain incline, I would power through it instead w the Buwizz app. All the controls were set up accordingly, but for the life of me I can't figure out one thing - how can I have the steering reset to "straight" after a turn. I want the steering to be identical to the Technic app, but w/ Buwizz, steering the 4x4 keeps it turned left or right, and its so hard to control like that without the reactive steering.

[@RacingBrick]

The BuWizz app does not support yet return to center steering, you need to wait for an update from them to have that resolved.

[@sailovspider]

Efferman's moc based on 42099 is the best. Stock chassis is ineffective in any configuration

[@meil.519]

When you swap all the gears (all four sets), performance is the same as effermans.

[@iphone7149]

your tires are on backwards,, much less gripping power. I had tires with this arrow tread on backwards on my bike and when I braked hard, I did well over a 360, I spun around almost twice.

[@RacingBrick]

Now try this with a LEGO car and you'll be surprised

[@swatibhosalay815]

Fourth

[@basberend]

this set needs the strength and speed of the buggy motor,

[@scottwhibley8392]

Is it just me or dose the set look better without the stickers?

[@zuanverreynne8301]

@Racing Brick, could you please make a video on 42099 with normal wheel hubs? That would be great! So that we can see how fast it can actually go

[@KaptenN]

Now to use a clutch gear to automatically switch between the speed and torque configurations depending on the resistance.

[@Qui-GonJohn]

Thanks for this terrific upgrade

[@jliu1596]

def upgrade. Stock version isn't like a high speed racer anyway so better imo to sacrifice the speed for lots of torque.

[@billyjoesamules9806]

What if you combine the both to make an 8x8 with rear steering

[@billyjoesamules9806]

And see how that gose

[@Hide_and_Tweak]

wow! the 42109 and 42099 sets are really not well engineered... With a proper set of gear, you can climb super steep hills with only one XL motor. So, with 2 XL motors there is someway to make it fast and strong. I've actually purchased a second XL motor and I can definitively make something much faster than the original 42099 which also have two XL motors...

[@KastaRules]

Is it possible to achieve the speed of the default version and the climbing capabilities of a stage 2 mod at the same time? Perhaps with something like an SBrick or BuWizz? Using a gearbox would allow to switch between speed and torque but with the double engine configuration it would be really difficult to implement.

[@RacingBrick]

SBrick does not change anything with speed or power, that's just a Bluetooth controller. With BuWizz you can get a higher voltage, but that requires Power Functions motors, and they require a fully redesigned base.

[@KastaRules]

@@RacingBrick I see. Only a scratch made MOC with a gearbox could have the best of both worlds then. The upcoming set 42114 could be helpful in this regard, it looks like it will have an actual gearbox unlike the rally car.

[@SubscribetoAthinandAnay]

He bought another one for us and he is a kind man for giving us information we love you racing brick go subscribe to this man let’s get him to 100k.

[@robl39]

Mr. RacingBrick - Do you know why Lego doesn’t make better motors? I would be willing to pay much more for these sets if they had better motors. Or even if they sold them separately as an upgrade.

[@RacingBrick]

Define "better"... it's a toy for kids, and as such the system does not really need more powerful motors. Plastic is easy to break or bend, even with these motors.

[@robl39]

@@RacingBrick You make some good points. What I guess I meant was it would be nice if they had faster and more powerful motors available. As you know many of these sets are painfully slow.

[@Brickabrac]

Nice 👌

[@MrAmorti]

If you want major climbing, get didumos's rocky b-model

[@RacingBrick]

Been there, done that :) But it also requires locked diffs for the magic :)

Can you add weight inside front wheels to prevent tip over?

What a great helpful video. THANKS. please do one for the 6x6 Volvo A60H too!!

[@RacingBrick]

I already have 2 videos about that set :)

[@Hide_and_Tweak]

I think because the differentials are opened, you lose a lot of torque. Locking differentials would probably help with obstacles.

[@Bmr4life]

But then it would turn horribly.

[@Hide_and_Tweak]

@@Bmr4life no, the wheels would just slide a bit to reajust, and it does not matter at all in an offroad context. When you drive an SUV or a 4X4 truck on asphalt, you need opened diffs, but that's pretty much it.

[@GJBricks]

I was thinking like @KennyMinigun. It would definitely benefit from a gearbox of some sort. Shame the Land Rover gear box causes the motor issues. Need a middle ground

[@meil.519]

I swapped all of the gears

[@EvanMoon]

I would enjoy seeing what adding more motors could do. Duel motors on both ends

[@defaultdaniel]

Cool video man, I just got mine today and am enjoying it. Definitely wish there was a little more stock torque and / or the bluetooth motor didn't cut as much power. Now for the real question - say I want to do the opposite and make it faster than stock? I should use an even larger gear on the drivetrain motors?

[@RacingBrick]

I don't think there's a point to make this 4x4 faster, even in stock form it can barely climb anything because it is tuned more for speed and not for torque. Theoretically you can swap gears to make it faster, but for that you'll need to make some structural changes since the bigger gears won't fit in the 3 stud wide spaces where they are currently located.

[@defaultdaniel]

@@RacingBrick I was thinking about using an old gray technic 24 tooth gear on the motor and the extra small 8 tooth gear on the bottom, but I haven't test fitted yet

[@GreatBallPit]

Nice upgrades and explanation. 👍 I should upgrade the one I have, or take it apart... :P

[@MrAmorti]

Now you have two, would you race them one with brickcontroller2, versus one with TLG's app?

[@RacingBrick]

Not many differences with this one as it does not have the virtual gearbox of 42109

[@MrAmorti]

@@RacingBrick yep, after I typed it, I thought to test it myself by timing across a set number of floor tiles. The time was exactly the same.

[@betterthenspirit]

i did this except i put it in a gear box, its kinda bulky but it works fairly well, and ye.

Show us!

[@zuanverreynne8301]

@Racing Brick, since you have two 42099s, could you please make a video where you compare 42099 with the Control+ App and with Brick controller 2 like you did with the Top Gear Rally Car to see if there is any limit in the App

[@RacingBrick]

The app is not limited for 42099 as there's no virtual gearbox, there would be no difference

[@zuanverreynne8301]

[@przemekwojcik4450]

let me remind. do you have comparison of all the pf nad powerd up?

[@RacingBrick]

I don't have a full comparison of all parts since new PU components are popping up every month. I did a comparison when the first set of Technic motors were introduced - kzbin.info/www/bejne/gZPTnoGseK98Y7M

[@Maxiie_TM]

This is good video. I love this kind of video

[@McKrushi]

I changed the gears directly at the motors to 2*16, so it's easy and fast to switch between "super slow" and "slower than original, but faster than 5min upgrade". That's a good mix for me.

[@Void_s]

So, there are four possible combinations (in order of speed decreading and torque increasing) : 1) Original (20:12 + 20:12) 2) Slower (16:16 + 20:12), which also turns the "5 minutes mod" into a Crawler mode. 3) "5 minutes mod" (20:12 + 12:20) 4) Crawler (16:16 + 12:20)
