Testing LEGO Tank Suspension...

Can you make a nuclear warhead out of lego

The test would be more accurate if you've used sprockets with no teeth in the suspension. In this case, the teeth were caught in the treads, causing way too much vibration and sometimes even the kickback

Very impressive how well you managed to reproduce the jarringly uncomfortable ride the Christie suspension was known for.

"Keeps track tension" The Chieftain liked that.

Now put a laser pointer in the cannon and compare each suspension's effect on accuracy.

As a bit of a tank enthusiast, I’m very impressed with how well these suspension types were implemented and demonstrated, but I do have a few suggestions that are also echoed by other commenters. Firstly, having the drive at the front of the tank causes slack in the section before the roadwheels, potentially causing problems and instabilities. Changing the drive to the rear of the tank would help with this. This was a historical problem encountered in WWII, specifically both the Americans with the Sherman and its predecessors as well as the Germans with their Panzer III, IV, Panthers, and Tigers (I and II), so it is an easy error to make. Speaking of German tanks, interleaved suspension would be interesting to explore, and comparing how it stands up to normal suspension. Secondly, as @k0lliak553 said, the roadwheels and the idler wheel (or tensioner wheel) should be straddling the center ridge on the tracks, like the return rollers are, rather than meshing with the tracks. This also causes a lot of instability in the tracks, and it should improve the performance over terrain Thirdly, a lower center of gravity would be helpful in lowering the amount of motion the suspension would undergo from the momentum of the turret, improving the ride of the suspension. Another point would be to increase the amount of roadwheels by making smaller versions of the suspension types or a longer tank, comparing a setup like the British Churchill with a ton of small roadwheels to something like the Soviet T-34 with fewer roadwheels. Either way, it is still interesting comparing each type of suspension, from HVSS to VVSS/Christie suspension, and modern torsion bar suspension, and I’m sorry if I come off as a bit pretentious or annoying, I just like tanks and it’s 3am so I’m tired lol. I just think that it could be taken to an even more interesting and in depth exploration with a bit of research and comparing historical concepts, as there is plenty of information surrounding WWII tanks, and it can show the sheer speed of advancement that happened over that 5 year period and beyond. Alright now my yap sesh is over, and imma go sleep lol.

Plot twist, these videos aren't edited, this guys just a lego wizard

One inconsistency i would like to point out is the different sized sprockets used, as larger wheels will always provide a smoother ride regardless of suspension. When i built my flamethrower tank (butane canisters) i played with a few suspension types. The best one i used was a hybrid of torsion bars and the horizontal but with considerable sag when the machines weight was exerted on them. Tortion bars provided the spring and every set of 2 wheels could also 'rock' in opposing directions. The softer force made the whole ride smoother and less bouncy. Plus when the weight lifted off a wheel it had room to move down with the track but still provided some support while the rest of the weight is being soaked up by the neighbouring wheels. I also learned that a higher amount of small wheels is better than fewer large wheels. That way changes in terrain have less effect on the whole suspension as a collective because it is spread out. The best way to imagine it is if a wheel were to break off, which system would shrug it off like nothing happened. Sorry if im going on a bit of a tangent here. Track suspension has fascinated me since i was a kid :)

Next video is going to be how you made a shooting mechanism insinde that tank? I'd appreciate that lol 😅

Wow... the part at 12:35 is insane. So so so smooth with the editing and filming. AMAZING JOB

Wow, I really like the originals ways of using suspensions on a tank 👏

Love the ASMR, please include more attaching lego clicky sounds!

Even Thanos can't snap his fingers that well. 😂

With the Christie suspension, using stronger springs as well as toothless wheels would help smoothen a lot. Some extra mass may help too, specifically towards the bottom of the tank in order to keep better balance

Okay, I have been watching these for over a year, and they have become a lot more entertaining with your personal flair sprinkled in. Sure the technical aspect is wonderful, but this video comes across more polished somehow. Sweet tank!

Sooooooo, you basically made a KV-2 or what I call “The Cube”.

Your passion for LEGO Technic really shines through in your work. I can tell that you put a lot of time and effort into your creations. Keep up the great work!

As someone who likes tanks I'm glad you made this video, really helps with understanding the different types of suspension. (I also like LEGO's and what you make is really cool)

problem of this tank is that its point of gravity is too high and the tracks have small lenght of contacts on the ground, but still nice experiment!

Cool to learn about the different types of suspension. I love how educational and cool your videos are!
