[This review was collected as part of a promotion.] It was nicely stacked and packed for building it from scratch, what an engineering marvel to build this truck. It took me 4 days of continuous effort to enjoy me building this monster truck. In my true opinion I enjoyed more building (assembling) Legos piece by piece. it refreshed my mechanical memories. I absolutely enjoyed 4 days of building effort and playing after it was fully assembled. It was like watching a baby growing up.

Absolutely great brainer product

LEGO

As built, this is a challenging model with incredible structural strength. As built this is a 4x4 truck that can handle minor off-roading. As built, this is a fun truck! We had wet snow falling the day after I built it and I took it outside. In 1/4" (7mm) or less of heavy wet snow the truck did fine, but once you got in to deeper snow it would stall once the snow built up under the differential. Not very impressive. This is why this is a 4 star model. 

How to get to 5 star? Below are three changes you need to make, extremely easy if you built it this way outright, if you need to modify it look up on YouTube the 5-minute fix for the 42099 model. This little set of changes does two things, it cuts the speed in half, but it allows you to run in 1.5" (38mm) heavy wet snow and keep going. I drove around for over 20 minutes until I finally pushed my luck and high-centered. 

5 Star truck! You just need to do the following three things!

Halve you speed, double your power. Thanks to Youtuber: RacingBrick

Step 78 - use the tan gear from step 82 not the black one
Step 82 - use the black gear from step 78 not the tan one you already used
Step 159- left side of the picture, there is a black and tan gear, carefully swap them. 

Have Fun! Remember, LEGO allows you to explore! Never forget that!

A 4 star model with a 5 star option!

I was really motivated from that tower challenge video, that I went out and got this kit, as well as a FPV camera, and Receiver Monitor. I struggled mostly with trying to manage the cables in segment TWO taking almost FIFTEEN minutes to route them without them popping out, and wanted to give them enough slack as well (bit of a perfectionist trying to get it to look like how it was in the book). I was surprised this kit didn't offer a Model B variant chassis to build with other parts, though not really disappointed since this one turned out great without any of the stickers. Overall it was a great experience building it, and am having a ton of fun with my FPV RC Truck!

Great Kit to get started with FPV

Samuel

[This review was collected as part of a promotion.] I got this for my 2 kids, 9 yr old and 4 yr old. My son really just loves to look at cars and trucks so this was a no brainer. My daughter is super into legos and we started to work on this together. My son had fun putting on the sticker decals. Unfortunately, I had to finish the job but it was super fun for the kid in me too. I do think the recommended age is accurate as an older kid would probably want to spend more time with building it. But, being able to then use the app and control and drive it around made it so much fun. The motors are actually strong enough to go over small things which makes this "off road" toy actually work. The app was super easy to use even for my 4 year old, so he still gets to play with it. YAY!

I immediately started looking for the other builds in this product line. This is a great toy!

Such an amazing Build and Toy

My wife bought me this for my birthday knowing how much I love legos. This was my first Technic set so was kind of challenging. Took me 6 hours but worth it. Final product was amazing. Played it for two days.

First Technic set and I love it.

Hi, I'm Juan and I'm from Chile. This Christmas I asked for the 4x4 x-treme and I loved it. I have never built sets with such complex systems before.
the app is really good and the car is very flexible. I have several legos but this one has been the most challenging and entertaining.

incredible

Fun to build. On the app, to me, the controls are reversed. Steering on left gas on right. Takes a bit to get use to. Fun to build. Not repetitive at all. I like displaying more than playing with it. Mine seems to pull to one side when driving.

Built this with my daughter who Is showing a intrest in lego that I've built so thought ok get this one and the rally car .
The build was ok and no real problems.
Only down thing which I found and so did my daughter with both models they just don't go fast enough for kids .. my daughter loved the app control using the touch screen control . But today's kids want speed ? So please lego change the gearing so future models go quicker, as my daughter who's 9 get fed up with it going so slow .. I will look and see if can change the gearing myself for her but most wont and just give up on it..

Great start with the app control ...

Despite a price that may seem high considering its number of parts, the integration of 3 engines and the new Hub must be taken into account in the overall crap of the set! An aesthetic that I particularly kiff with a crazy color code, I really like its design! The set is robust (for having him make barrels... I confirm) On the other hand, clearly he lacks torque for the crossing and his ground clearance is limited! Nevertheless, for the couple, a very simple modification of two pinions allows to give it much better capacities! To finish as it is, the app is super intuitive and the kids will enjoy (the less young too) For the curious, a video on my Youtube channel where I explain everything: Geekme3

A really stylish 4x4! A beautiful toy!

It's a good set with which you can have everything you need for a first remote controlled LEGO car with suspension, it has good challenges on the app, easy to connect and quite complete, even if it sometimes lacks a little torque. At first I found it so expensive for the quantity of parts, but now I think it's a good price to have the new Control + system, 3 engine and enough parts to make my own cars. Plus, I have the set 42110 (defender) and with this one I can do it remotely.

Good car 4x4 and Control+

Callie

I love Lego and building with Lego but not this one. I did check to make sure my phone would operate this but after purchasing and assembling and getting the batteries for it the control would not download on my phone and I could not operate this. I held on to this for several weeks hoping I could download the app but never could and sent this one back. :(

Would not work
