Two motors, tracks and a remote control. Seems simple enough. Does this equal FUN? Or do you need more?

This is the 2nd remote controlled tracked vehicle with PowerFunction, after the 42065-1 RC Tracked Racer. The idea looks good. Remote controlled vehicles always means play fun. Let's see if it works.

The Set

Pull high-speed wheelies, spins and turns, and traverse rough terrain with this fully motorized LEGO® Technic™ 42095 Remote-Controlled Stunt Racer. This tough model features large ground-gripping tracks with large rear sprockets for optimal acceleration, plus a modern design with a fresh yellow and blue color scheme and decorative stickers. Drive forward, backward, left or right and make 360° turns. Rebuild this 2-in-1 remote-controlled tracked vehicle to create a Remote-Controlled Racer for a double build-and-play experience.

The Box

The box measures 382 x 262 x 71 mm, and weighs 790gr. Inside we find 3 unnumbered bags, the instruction, a sticker sheet and the loose powerfunctions.

The Instructions

The instructions measure 279 x 211mm. It has 71 pages with 86 steps.

The Parts

The set contains 323 parts and 7 spare parts, in 12 different colors, and 18 different categories, with a total of 78 unique parts/color combinations.

Main colors are:

Main categories are:

There is 1 new part in this set: 42529 Technic Tread Sprocket Wheel Large Diameter 7 Holes

There are 2 parts rare in Dark Azure: 11946 Technic Panel Fairing #21 Very Small Smooth, Side B and 11946 Technic Panel Fairing #22 Very Small Smooth, Side A. The only other set thses parts come in this color is the 42083-1 Bugatti Chiron , and recently the 42098-1 Car Transporter.

The Build

The build is very straight forward. Dare I say even boring? The focus clearly leighs on the playability. The build is little more than creating a chassis for the motors and tracks, and slap on some panels for looks. The only nice detail is the headlights. They used a paint roller as a bracket.

The endresult is not ugly, but it won't win any design awards either.


Because the build is so simple and quick, I've also build the B-model, which is similar to the A-model, but wider.

There is also a MOC for this set, that claims that by moving the motors from the small to the large sprockets, this version is faster than the B-model. I've build this MOC as well, to test the theory.


The first thing I noticed after building this set: It does not have any grip! I tested it on a stone tile floor. The tracks skid a lot, and taking a corner puts it into an uncontrolable spin. I can't understand why LEGO didn't include some 24375 Rubber Technic Thread Attachment. I've added 1 on every second track, and this improved the driveability a lot! These are cheap, small parts, that won't add much to the cost of the set.
A quick test on a short straight track shows the following results (with rubber inserts):
Model A: 5.2 sec
Model B: 6.1 sec
Model C (MOC): 4.8 sec

The build itself is uninspiring. There are no clever techniques used, and the endresults is a bit dull. The aim is clearly to play with this set. But that is also not great. Driving a straight line is tricky, because the motors aren't going the exact same speed, so there is a always a bit of wobble. Steering is also tricky and requires some practice.
And then there is the price. €119,- for 323 parts, that comes down to a whopping 37 cents per part. This is clearly because of the PowerFuntions, but still, it's a high price for what you get. Nope, this is not a set I have enjoyed.

    Thank you for telling about 24375 Rubber Technic Thread Attachment! As for the playability it is worth mentioning that both Model A and Model B have no dust protection, so axles, gears and other moving parts will suffer greatly when driving on a dusty ground or sand. But these are one of the few types of terrain where steering is actually effective.
    For me and my 5-year old son this was our first Technic set. This set was bought as an experiment and simple RC model that, if not satisfying, could be disassembled and used to build something else (additional gears were bought to show my kid some mechanics). We played with it at most 10 times during last 6 months. Few weeks ago we found a way to make it more joyful: you can play polo with it! We added a bumper with two horns wide enough, built a pair of gates and now we play by catching a ball between these horns and pushing it into the gate!

    I build remote car c model from this set!

    Yes it's a nice  set for expanding power functions (got it for less than 50 € from amazon and it still selling for 55 € currently).
    It still strange that it came with PF when PU was already available. I second the fact that rubber technic should have been included. It's also a nice dark azure part pack if you already own rally car, tow truck or chiron.
    If bough only as a toy, I think a dedicated toy will do much more, for more or less the price (my son own a nikko velocitrax which is way faster and sturdy for the same price tag at the time of buying).

    I saw a boy having tremendous fun with this set. He didn't mind at all that it was difficult to steer. Perhaps he even found it more fun. It did indeed skid a lot on a hard floor, but he didn't find that a problem either. The grownups however were not happy with the noise, so maybe for them the thread attachments are an improvement for them. On a more rough floor, the machine lifts the front up  (staggers, or what is the word for cars?) when it launches at full speed. So, altogether, wild, raw energy unleashed in this little racer! Perhaps boring to build but tonnes of fun for the children playing with it.

      I do agree with you, it skids a lot, straight lines are difficult to drive as it wheelies, but that it's because the designed itself, and let's not forget it's aimed at 9+ kids, so for them I do believe all these features proportionate them plenty of fun, I'm 35 and this is my PF set, and I enjoy it a lot as well.

    By now, this set can be bought in my European home country for less than $65, while buying just the power functions components individually will set you back over $80 altogether. So if you want to expand your PF collection, this little guy is an excellent parts pack!
