Quick Q&A...
Q: Why does it steer to the right?
A: Because of the knock of Servo... Lego does not make PF Servo Motors anymore. As a consequence people have to buy one from Bricklink for up to 80€ (per Servo motor) or get a cheap Servo from a 3rd party manufacturer. And these non Lego servos are very bad. They do not allow partial steering, some do even overheat and they don't last long. The one you see in this video is about to die... I am lucky I could still make the video.
Q: Are there instructions?
A: Unfortunately not. I need my time for videos and building. Making instructions would mean less videos. Plus the number of parts and motors make this build very expensive to replicate. Only the Buwizz and the motors cost more than 250$.

there are not enough thumbs in this world for this video, outstanding job

[AwesomeDomi]

I knew this could be done in Lego, but I never expected it could be so compact as well! Seriously amazing job

[BillBoard.]

The ratio of a full scale car to the size of this model car is the exact same ratio applied to the UNDERSTANDING of how the transmission of a car works. Immensely GREAT work!

[Dan-shrv]

seeing the transformation from 3:12 to the compacted build in the car is jaw-dropping

A true lego master. As a mechanical engineering student, auto/motorcycle mechanic, and lifetime lego enthusiast, this was beyond enjoyable for me. Thank you!

[moctawolf]

Congratulations. You have built the most complex and compact technical lego build.
Simply unbelievable.

[mancazziashm]

This could easily be an official set. Absolutely fantastic.

[LEGOCOOKING]

so impressed with your video, keep it up buddy

[josephius]

Lego needs to hire this guy! Incredible! Not only does it function incredibly well, but you made it look great as well!

[Driftuner]

Wow. As a test-driver and development engineer i have to say, youve built this thing way better than some manufacturers i have to work with, no joke....

[filippus_]

I truly believe this guy should work for lego, this is just amazing!!

This is the first fully functional gearbox I've seen on Lego. Also attention to details like positive caster angle etc, unbelieveable. What could be added, as a showcase, is disk breaking system, which is redundant on electric vehicles on small scale, and maybe limited slip diff. In that case this is the ultimate lego RC. Cudos. I loved the video.

[KrisRatliff]

Your understanding of engineering, gear ratios, Lego, and artistry are through the roof my friend. I geek out every time you put out a new video. What you do is just so fun to watch! I wished I understood better all that allows you to do what you do, but regardless of my level of knowledge, your channel is just a joy to watch. Cheers!

Lost for words.. this is the most incredible thing. What an amazing talent you have for using Lego, engineering and videography. 10/10

[FromThaJump]

Can I just say that it was HILARIOUS when you switched to the thermal camera view on the clutch. You never commentate, but that transition spoke 1000 words.

[HarmonicaMustang]

Anyone notice how in the compact version the clutch is the first to release and last to be reapplied? Small detail but incredibly important. Genius.

[netherite]

The fact it drifts as well just adds to how insanely well done this is

[Anikanstern]

As a MOC builder who uses Lego technic a lot I understand how long it takes to perfect a build. Trial and error, different version and techniques. I respect your dedication and skill.

[Frog-kouu]

Amazing build! Not only did you make a four-speed sequential shift manual transmission out of Lego, you made it insanely compact too!
