For people playing at home, a big part of what makes carbon driveshafts so great is the safety (on top of the obvious weight advantage). A normal metal driveshaft will bend, tear and keep spinning around causing chaos when it breaks. It'll punch through the floor, tear up the car and can even dig into the ground and flip you. A carbon shaft will basically rip itself apart and disintegrate. Still busted, still a bit messy but it doesn't turn you into a 200mph pole vaulter

[@SuqMadiq]

Mythbusters did that. I don't remember the exact outcome, but I'm pretty sure it fucked the car up.

[@helplmchoking]

@@SuqMadiq Oh yeah! I can't remember if it actually turned the car fully into a catapult but I'm pretty sure it left the ground. That shit is dangerous (and why drag cars run big steel hoops around the shaft)

[@workdesu]

@@helplmchoking u guys are talking about that steel driveshaft episode they did right? cant seem to find anything about them doing a trial on carbon driveshaft

[@helplmchoking]

@@workdesu Nah they didn't do a carbon one, but carbon is good at shattering rather than bending and launching your car into the sky regardless

[@EdwardM104]

@@helplmchoking funny thing is old Mercedes have driveshaft hoops for the same purpose. Nice to have an essential safety feature already there when building a car. I've actually had a driveshaft explode on an old W124 300D. 130hp maybe but we had put in a newer transmission w/ an aftermarket controller and the diff was worn out so after enough times of it slamming into gear, the flex disc exploded and the driveshaft bolts sheared off just pulling away from a stop light. Fun times.

Technically he started with a base model car, he just upgraded every single component on it to premium race grade/aircraft grade as he could and just keeps refining, testing, breaking, upgrading and so forth. He's his own shop, testing facility, research and development. I'm curious what this project will be like in a year from now, then 5 , 10 years.

[@mikeeyyss2150]

One of the most intricate builds I genuinely enjoy seeing. Insane.

[@tiaraguy7705]

I've always been impressed with how much research goes into creating these cars but the thing I've been even more impressed with lately is how you and your team understand that some knowledge is only attained by trial and error and you'll prepare days, weeks, or even months in advanced for things that you can't simply search up. The amount of times you've come across something that wasn't exactly an issue at the time, noted it down, made measurements, and even made marks for reference just to check them months down the line and making sure to tell us astounds me. It shows that this is nothing like a hobby or a passion, it's a whole different life at this point. You really do live and breathe this stuff and it's been most enjoyable to watch.

[@Cynical...]

Holy shit two mega long episodes within 24 hours of eachother?! Best valentines ever, give Isaiah some extra belly rubs from me please Rob

[@khobaibzafar3601]

Kudos on everything you've done in this small revision. It's a crazy car and will only get crazier

[@zachbowles4842]

Hey rob, the reason the end plates on the wing are ‘upside down’ as you think, is because most of the downforce occurs under the wing, on the underside of it, not the top. Similar to an airplane wing. But opposite, downforce, not lift

[@mavisky]

Came here looking to see if I was going to have to be the one to call him out on that.

[@zachbowles4842]

@@mavisky we always here to support big daddy dahm. even with my little bit of knowledge

[@mattypontheroad]

This comment needs to be higher.

[@Olimorveu]

Indeed it prevents higher pressure air from the top of the wing spilling into the low pressure zone under the wing.

[@justincharles6585]

I hope he sees this

[@joshmammen4285]

I may be drinking but when you show the car at 33:01 I shed a tear. I am so happy to see the dream coming together, and the progress you have made since the beginning. I am truly blessed to be in this time period where I can see someone with true passion learn and create their dreams by hand. I am also so happy that you found a group of true friends that have shared the dream with you and put in endless hours to help create this fucking gem I see now. I hope you never stop striving for perfection and creating purpose built machines!

[@Spademonkey]

I love how far this has come, and how these two work so well in tandem together. Seeing them both sign the patreon posters together was a really great sight to see. I met Rob at the start of a road rally in San Diego 5.5 years ago, was a great person, and glad to see that hasn't changed after these years and his passion project has come this far. To more and more success and progress!

[@Andrewlang90]

It can not be stressed enough how beautiful the 4 rotor is. This is a work of art at this point. You’ve left no stone unturned, left nothing to chance, and built the most cleanest and beautiful ride on YT, and in general. Ahura is smiling, well done Rob and Isiah

[@JD86Vintage]

FYI, you were right, the end plates for the wing are for containing the airflow. They're to stop the air taking the path of least resistance which is not over the face of the wing but off the side. The reason they point down, not up, is it's actually the underside of the wing that generates the downforce. So it's more important to contain the air on the bottom than on the top face... The same principle is why swan neck wings are becoming so prevalent. If you mount the wing by the top, it leaves more area for smooth uninterrupted airflow on the underside of the wing.

[@EnzoM]

Something about that spoiler looks seriously off, for some reason. Like it doesn't match the car, at all. I'm not quite sure as to why but perhaps it's too high up, too far back, or just too big. Or maybe it's the shape? Maybe all of those? Idk... It's size definitely looks a bit -diving board- overboard, and it's shape does not flow well with the rest of the car. I get that it's just a first spoiler, though, and things will most likely change in the future.

[@Kris-bp4td]

That spoiler does not match the 4-rotor's looks, at all. Something's really off about it. I'm sure it will do what it needs to on the track, but it's definitely a function over form situation, where with the rest of the car form is paid just as close attention to as function.

[@umbraelegios4130]

30:46 Can not belive you passed up a "That's what she said" moment.

[@MRcustomracing]

Without getting to deep on the aero rabbit hole, when mounting the endplates, they are used to speed up the air under the wing. Given the air pressure differential being the cause of the downforce, the bottom side of the wing is more important that the top, hence all of the gt cars have all switch to the top mount style wings. Short answer, hot Boi look is right

[@jordansmith567]

Hoping this response gets more attention. Was watching that part crossing my fingers that they figured out the correct way to mount the endplates.

[@jordansmith567]

Since Rob goes through several iterations of designs as he learns and grows, my hope is this was just the quick option to find a passable solution to the downforce imbalance. I would love to see a swan neck design or possibly a multi-element wing in the future.

[@MultiTravellingman]

Rob, your team and yourself do amazing work. From welding, fabricating, testing and refinement. However there are tons of small things I've noticed that you could tweak and upgrades that aren't expensive that will make your work better and safer. A quick example is in this video, at 12:13 you are using what looks like a basic set of plyers to act as a spoon for filling grease into the axle joint/hub. For starters, a quick phone call/text/email to the company would get you exact info on the amount needed of grease to add, when it comes to your life and others don't gamble and wing it unless you have to. You just broke an expensive part and have a replacement one, find out how much to add, why it needs to be that amount and what happens when there's less or more then that amount... besides not being accurate, you're potentially risking scraping the metal inside by coming in contact with your plyers. Get yourself a caulking gun, and that grease should be available in a caulk form, or can buy empty ones and fill it yourself with the grease. Pump it into the area you want with precision and because the tip of the caulk is plastic/silicone it will never run the risk of damaging the metal unless you really ram your caulk. If you don't want to go that route then at the very least look at heavy duty silicone spoons, scrapers to make the job cleaner and easier.

[@racerx2084]

Can’t wait to see this tv series. I’ve watched sone of the other KZbin competitors videos and it’s pretty stacked up with all the cars. Also I hope the hood is salvageable from the itty bitty clip I saw from the boosted boiz of you ripping down the drag strip. The 4rotor was one of the 2 biggest hits so far from what I’ve seen. There was another na 4rotor there. The sounds make everyone speechless.
