The Rotabuggy Was Vehicular Evolution Gone Wrong... SO I BUILT ONE

Welcome to another episode of Trailmakers! Today I am attempting to recreate the Hafner Rotabuggy. It looks like the offspring of a helicopter and a jeep combined, but it is actually more of an autogyro than a helicopter. It was designed to glide onto the battlefield after being towed by another aircraft. I've never tried to build an autogyro before, so let's see how it turns out!

About Trailmakers:
In the toughest motoring expedition in the universe, you and your friends will build your own vehicles to cross a dangerous wasteland. Explore, crash horribly, use your wits to build a better rig, and get as far as you can with whatever spare parts you find on your way.
Welcome to the Ultimate Expedition!
Journey over grueling mountains, hazardous swamps, and bone-dry deserts on a distant world far from civilization - it is just you, your fellow adventurers and the amazing, jet-powered hover-buggy you built yourself. Explore, crash your vehicle, build a better one, and get as far as you can with whatever spare parts you find along your way.
Trailmakers is about building very awesome vehicles and machines, but you don’t need an engineering degree to get started. The intuitive builder will get you going in no time. Everything you build is made from physical building blocks. Each block has unique features like shape, weight and functionality. They can be broken off, refitted and used to build something new. Individually the blocks are fairly simple, but combined the possibilities are endless.
Expedition Mode is the challenging campaign mode of Trailmakers. You are competing in an off-world rally expedition with only a few building blocks to get you started. You must build, tinker with and rebuild your machine to progress. Journey through a big world, overcome deep gorges, angry wildlife and dangerous weather to progress and find new parts that will juice up your machine. The world in Expedition Mode will test your survival skills and ingenuity.
Sandbox Mode is where you want to head for an unrestricted, sandbox, vehicle-building experience. Here you can build anything you can dream of, and play around with it in the world of Trailmakers. It is a great place to test out crazy machines, and experiment with the physics engine. With tons of different blocks, hinges, thrusters and interactive vehicle parts - the skybox is the limit.
Trailmakers is even more fun if you play it with other people. Build cool vehicles and compete in mini-game modes with your friends or other Trailmakers online. Build a helicopter, send it to your friend, and shoot them out of the sky. Put two seats on a tank, and let your friend control the turret. As we get further in Early Access development Expedition Mode will also be adapted to multiplayer.

As somebody once said ..."That's not flying, that's just falling ... with style" ;-)

[@italianhillbillytexan]

Yes sere

[@NetralFN]

Flying tank be like

[@poonamsaini741]

🤛👏👏👏

[@Targetstrike]

Ah yes Toy Story moment

[@BeefIngot]

The rotochute would have theoretically allowed them to autorotate to a safe landing slowing down significantly before actually hitting the ground rather than glide.

[@quakxy_dukx]

I was hoping someone would say that the principle mechanic is autorotation. Another interesting fact is that in the case of an engine failure helicopter autorotation is actually far slower and safer than a plane gliding

[@daniellclary]

I bought this game a few days ago because of you. I am doing the story mode thing. I tried making a plane with the parts I have. I only have the basic modular wing, the first steering hinge, and the booster jets, which have a cool down. Say the least, its a sketchy bird to fly. I call it CAWW! But the creation I like the most so far is my shark. Its so cute when it picks stuff up in its mouth.

[@TastelessCub797]

If you need a reliable vehicle, put a propeller on a seat with fins and you have a really fast and just as sketchy helicopter.

[@moroblizniak4457]

1:39 new cannon has more dmg, shoots further and has slower reload. Also blow ups on contact with water, not going under. Loking forward for ships battle on Your channel with the boys.

[@antoniolozic1517]

Hey scrapman here's a really cool idea for trailmakers, try recreating the ME-163 rocket powered plane prototype, it's weird looking but fun to do, or other ww2 experimental german planes and other prototype vehicles as such.

[@moroblizniak4457]

It's just plane with extra steps...come on.

[@rhythm2620]

Wow just found a super cool video on its flight, pretty funky lookin plane, I second your suggestion! Link to flight: kzbin.info/www/bejne/eH-soX2ZhL-DoqM

[@unholyhardy4359]

Isn't that the thing from Spy Kids?

[@kingwitherasher4628]

Hi scrapman i like real life vehicles brought to that game and being historically correct. thanks for the content.

[@SecureGM]

Just add a spring mechanism that accumulated energy during the fall and activates just before landing to allow silk smooth landing.

[@the_Acaman]

The total energy would be the same so the end result would likely be too

[@DigitalJedi]

@@the_Acaman It would arguably be worse, as any mechanism will not be 100% efficient at storing and releasing the energy, and would add mass.

[@kepstin]

I think the way you'd do this in a real autogyro is by having the blade pitch adjustable. As you go down, the blades pick up speed - and then right before landing you change the pitch so it generates a little bit of lift from the stored speed to slow you down.

[@SonOfmowgef]

I'd still like to see you re-create Danté, the volcano exploring robot. It had a walking mechanism that should prove to be a challenge to make in Trailmakers.

[@rhythm2620]

That would be an awesome walking mechanism for trailmakers, I'm gonna go build that now lol

[@THESLlCK]

looks pretty basic

[@The_Guy_Who_Asked72]

That would actually be interesting

[@i_forgor7268]

YESS FINALLY, TYSM scrapman you finally made it

[@somedude4227]

LETGOOO

[@somedude4227]

you did it boy, you did it

[@Sportkid-wi7zw]

LETS GOOO

[@i_forgor7268]

TYSM FOR THE SUPPORT GUYS!!!!

[@cyberwolf5075]

Yayyy

[@JustWillB]

Hi Scrapman, For an autogyro the rotor blades actually need to point downwards (i.e. a negative angle of attack). That way the air passing up through the rotor disc accelerates the blade rotation. As the rotation of the blades get's faster you can reduce the negative angle of attack in order to generate more lift. But it always points down. if you look at your rotorbuggy the wing segments are going backwards compared to their normal direction. This is why.

[@JustWillB]

Also to take of from flat ground make the rotor disc lean backwards a bit. That means air rushing past from the front goes up through the rotor disc and accelerates the downwards pointing blades.

[@Orkzslayer]

The Autogyros you found are also called Gyrocopter. They are producing lift by angeling the upper Rotor in the correct position while getting velocity by the small rotor.

[@owenkegg5608]

Autogyros will generally function better with a small flywheel of sorts (or just by making the rotor heavier) in early and late stages of flight by providing more lift.

[@shwellava]

You should check out the Cyclocopter

[@moroblizniak4457]

Yes

[@quakxy_dukx]

I can’t help but laugh whenever I see the word cyclocopter because clearly whoever named it didn’t know that the etymological breakdown of helicopter is helico pter meaning spiral wing which would mean cyclocopter would be broken down into cycloco pter which doesn’t make sense. Cyclopter however does make sense by combining the intended cyclo and the original pter. Also that was a really long sentence

[@matthiasm.official331]

It's nice to see that You try to build anything Your viewers came up with! Thanks for that! 😉👍🏻👍🏻👍🏻

[@ImVenrix]

this mechanic is called an autorotation and it can be used to land a helicopter in the event of an engine failure. you can try increasing the collective right before touchdown for a softer landing

[@freedom_liberty_democracy]

Now we need the rotatank Imagine if they continued it to the rotasub and the rotaship 😂

[@squiddudis7706]

Hey Scrap Man, could you try to build the strv 103, it's a wedge gang tank that uses it's treads to aim, super cool.

[@weeveferrelaine6973]

I would love to see it, it's my favorite tank

[@-dianthoraptor-213]

Finally!!!! Thx scrap man, never gets old..

[@Hlebuw3k]

The Ekranoplan is a massive Russian plane-boat hybrid, the pictures says it all. It was supposed to glide 10 meters above the water, removing the force of friction against it, lifting off with the whole front engine array, and then staying afloat just with the back low power engines and the power of the ground effect (when close to the ground, the high pressure air bellow the machine would lift it naturally). It was supposed to revalutianize water travel, giving Russians a huge advantage in military power. Because of how the ground effect works, the bigger the machine, the higher above the water it could hover, so the engineers invisioned huge airliners and military machines floating high above the waves. But, the small prototypes were not enough to impress the higher ups, and so the funding was not enough to build the final plans, and the project had to be abandoned.

[@turnedwheat2013]

I can't believe you were able to make it work, unbelievable! 🤯 Now for the rota tank 😂👍

[@nukeduke7018]

Scrap man can you make a wired tank cald the UDES XX 20 an increasing tank that have 2 tank hall.

[@langitn.a.absen1946]

This series in ironic, since you know; "History repeat itself"... and scrapman is continuing this series... and this series is about vehicle in history

[@souptime3070]

I like how Scrapman completely missed the fact that the whole roto section of the rotobuggy was supposed to detach when it landed 5:30 look at the lower part of the bottom picture there

[@greymatter1999]

I was thinking the same thing and was going to comment if I didn't see anyone else

[@tnapeepeelu]

Oh yeah

[@TommyCrosby]

This is why, in some conditions, helicopters are better for emergency landing than airplanes when losing the engine. They can use autorotation to slow down the fall and control where to land in a short distance. They can land everywhere uncovered right on the spot. Airplanes might have the "glider" effect giving you more time to react, but you still need to find a strip of land with enough length and glide there.

[@limehuzki]

As an engineer autogyros and helicopters alike use a ballast balance system so yes you are on base with the assumption, autogyros use their enormous weight and the counter rotating horizontal prop , my suggestion..... Add more weight on the center bottom, then make the propellers on a rotation point to generate lift once the top blades gain enough momentum

[@short0811]

15:57 is super satisfying! Good job on another creation working better than (at all) compared to the real design.

[@kitsnap1228]

Nicely done! Love your content, especially this protoype serie :)

[@TKMatthew]

That was a good hint you gave in the comments of the last video Scrapman.

[@TheDreruptp]

Flips over when you turn. Yup, that's a jeep!

[@omegafalconoriginal]

PART 2 needs to be adding the disc connecting. try making it were you get rid of rotor and tail just be fore impact and drive off.

[@mudgygaming3683]

Finally YES! Stabilizer mug in Trailmakers!

[@armedpotato_chip45]

I think it would be cool to see you build a Lockheed Martin Sea Shadow, or maybe the Cold War UFO.

[@hawkeye2b715]

Hey scrapman, love the prototype series and keep it up, also a good site for inspiration is the tank encyclopaedia if you're not already using it

[@nadatellin4866]

Just stumbled across your channel last week and fell into a KZbin hole really like your content, also had to get Trailmakers, Dude thanks so much awesome game I will likely be spending all my non TTRPG DM time playing, really brings out the Mad-Scientist in one....

[@Event_Horizon16614]

Thanks for telling me that the update finally came to console, I was waiting for what felt like forever

[@redpug5042]

for autorotation, you pitch the blades to dig into the air, then flip their rotation to transfer all the stored energy into a negative acceleration to land.

[@weeveferrelaine6973]

Already hearing Betty say "Pull up... Pull up" in my head, just from reading your comment, haha.

[@zippythinginvention]

I've just discovered your videos a couple days ago. Been watching for many hours! Thanks. I've got two ideas. One is like a tennis ball launcher. Like, two opposing racks of tires. Each pair spins faster than the last. So, any object stuffed between the first two tires is thrust between the next set, and so on. Massive speeds could be achieved! Probably an easy sonic boom maker. Second, wheels on wheels. Like, one big wheel with lots of smaller wheels around the perimeter. When they're all spinning, it might double your ground speed. It's probably impossible unstable though.

[@tnapeepeelu]

You need to tilt the rotor back slightly to catch the wind

[@buddydalastjedi2140]

You are so good at building. Keep doing what you’re doing 😀

[@thisguywalksintoa1267]

great episode, thank you

[@danielcampbell1660]

14:22 You’re falling in style

[@mathiasg8350]

1:12 "This is a damn fine cup of coffee"

[@FUGP72]

It was nice of them to put a target on the side for the laughing enemies to focus on while waiting for you to slowly get in range.

[@yjoth3977]

history : *makes an utter failure* scrapman : "... so I built one!!"

[@knotlegend5479]

Congrats Scrap man I cant believe you've gained this much subs that quickly ive been subbed sense 100k!

[@noahtremblay4429]

Now I think we all wanna see something like the ROTATRAIN!!!

[@exafawn]

Really liked the editing in this one

[@darkswordsman0633]

Hey scrapman, small modular wings with heli blades work at slowing you down. Sadly you need to be able to effectively control the way you fall with surface controls to level you out. If the smw + heli blades have their bottom facing the direct direction you are falling they will slow you significantly. Also, forward momentum with unpowered heli blades make the blades function more like stubborn wings.

[@mansengus940]

try recreating the war tank on one wheel. love your content!

[@Krokmaniak]

So it's basically Autogyro (it's actual type of flying machine used to this day) without horizontal rotor to gain horizontal speed in air. For my understanding with horizontal speed really help autogyro. Scrapman. You know what to do

[@TOPSYKRETTSHERE]

i am indeed on console and i was indeed upset that we didnt get the update. thanks for the headsup and great content

[@TheVideoGuardian]

This technique is something all helicopter can do, as a means of emergency landing when engines fail. Some flight simulators are accurate enough for it to work. When falling, the goal is to keep the rotors spinning fast, which both stores energy and also slows the fall. The secret to landing is then to gradually raise the collective just before you hit the ground, transferring the stored energy into lift. Not only can you reduce fall speed to zero, you can end up moving upwards again if you pull too hard. (Which is really bad if a soft landing was your goal... since you probably have very little rpm left at that point...)

[@burtard3983]

The scrap mechanics team posted on Twitter that the dev blog will come out soon

[@nic2097]

I like how if you fail in recreating something you look it up to see how others did it. Nice to see you don't just quit

[@jedisongaming7261]

Yesss thanks scrap man love you

[@snipersnipes4475]

Can you build the cyclomer, Scrapman? I think it’d be a fun concept, but it might be too easy for you. I’m not sure, though.

[@sovietducc1375]

I think ScrapMan is now obligated to complete the duo and make a rotatank

[@nickd.7475]

I love how the design sketches are done in crayon.

[@staceysheets3482]

I have an idea for a MM challenge there are 3 ways to do my Idea. 1 you all make planes with 1 pilot and 1 gunner and either make your own 1 person plane or use the same one person plane. 2 you all use the same 2 person plane and you make your own 1 person plane. 3 if you have 4 people you could all make 2 person planes and do a battle. The way you win is which ever team lives the longest and the way to win the first 2 is to shoot down the enemy 2 person plane in with the fastest time.

[@Bendigo1]

A few problems i noticed with this design. 1. The rotors were spinning the wrong way. 2, The blade pitch was too great and the wrong direction. 3. The rotor needs to be tipped back so that autorotation can occur while moving forward and not just while falling. I think if those issues were corrected, it might actually work as intended. I do not know how accurate the physics and aerodynamics are in the game, but i see potential in this design.

[@lenorelestrange]

Just started playing SM again after like 4 years and honestly really enjoying it, started watching your content when I was looking for build ideas and you're like one of the few SM youtubers that still does this game. If you have room in your little friend group I'd love to join yall in your mini games, I'm a bit of a tinker and I have a very entertaining personality. I stopped doing twitch to kind of move do my own thing and meet cool content creators like yourself and always enjoy playing with like minded people on fun niche games. hmu yo.

[@xenogryph7169]

@ 10:07 You made a flying frog! lol.

[@sethmarciante3626]

Something very interesting and quite unique would be the Me P 1109 ScissorsWing

[@fel1xisboodayuis696]

I like the inspector gadget reference

[@Jack51615]

imagine, you're a german soldier and all you see are dozens of jeeps falling from the sky. F*cking terrorfing.

[@shiny4984]

Nice, now that you made that, maybe make the arctic snow cruiser or the rotodyne You can watch mustard's video on either creations, they give you a quick and easy explanation thst gets you into the subject so you can read about it

[@nyscersul42]

Also, thats real nice, the hop into the workshop for help :)

[@PainApple96]

Now you HAVE to build the "Cierva C.4"!!

[@ElliotMarkussen]

Fun fact Autogyro is actualy called autorotation in helicopters if the engine fails

[@alexandervasquez9324]

You should do a rotodyne. It was a plane with a free spinning propeller that would use jet engines at the tip of the blades to spin them in take off and landing and during flight the actual propellers that provided forward motion would activate and the giant rotor on top would keep spinning because of the air hitting it and it would generate lift without the use of wings. It had prototypes built and was meant to be a cheaper way of transportation that would leave airports and big airliners obsolete in city to city flights inside the country being able to land on the roofs of buildings that had helipads. Removing the need to take a bus or a cab from and to the airport. But it didn't make it far. Mustard made a video about it and google also has some kind of helpful informatio. If I said anything wrong I am sorry this is just what I remember but something close to what I said.

[@Koljon]

Hey Scrapman, I would rally like to see the heavy gustav or in german the Schwerer Gustav. Its a giant tank on rails. Keep the good work on and never stop making such amazing Videos.

[@bowlinfool4304]

I’d like to see you attempt either an ekranoplan or a rotodyne. Although I doubt trailmaker physics are good enough for either

[@jacktedcastle938]

idk why but that weee at 10:58 made me laugh so hard

[@austinharbourn1045]

Next Project: Fairey Rotodyne! I love the Fairey Rotodyne.

[@EatMyYeeties]

So the idea with an autorotation is that you store up kinetic energy at a lower rotor angle, and then as you get close to the ground, increase the angle of each individual rotor to take that fast balde speed and turn it into a lot of lift and slow you down! So it'd be cool to see this with adjustable rotor angle and see if you can land it at an even slower speed

[@MechanicalFreak]

Great videos

[@stevesmith-kf9iw]

Scrap man your a good builder

[@microtheguyfromearth]

Cool!

[@lehazing5957]

hey just wanted to say that for "correct" auto-rotation (the one that helicopters use in an emergency) u need to be able to control the pitch of ur rotor blades.

[@Hlebuw3k]

The Rotodyne actually had a similar idea, it was a commercial plane-helicopter hybrid, with the helicopter blades providing the lift in horizontal flight, but it was too loud to land on the city buildings, so it was scrapped

[@TechbloxGame]

I'm curious if the Rotachute would work better if the person in the first image was rotated anti clockwise by 90 degrees. Maybe it would have provided greater stability. Love these historical prototype builds!

[@jonahscott7826]

Since wind was added to Trailmakers, you should make a rotokite.

[@cp_1916]

Wait I just realised wouldn’t it be cool if the trailmakers devs added angled shield Blocks to place on the side of wedge blocks?

[@quintonconrad5745]

The Toto shoot is how a helicopter without power lands it’s actually really safe

[@dasbratkeks3092]

You do a great job with rebuilding these weird vehicles! But can you build a "Rail Zeppelin"? 😅

[@Hlebuw3k]

I remembered there was a channel with a lot of failed (and successful) historical machines, its called Mustard with 1,26 million subscribers right now, there is a lot you can take inspiration from

[@AubiNation]

4:00 “they hadn’t invented colors yet”. Thanks. Now I have coffee all over my table and lap…

[@munchielovin]

This video is epic just for the return of the suspension mug.

[@utsavwhysytsobadrecently]

Hoping you make all of the rotachute evolutions

[@pcvids]

You should try the Fairey Rotodyne concept

[@dahgman3225]

Somewhere between gliding and falling... Buzz lightyear looks up and smiles

[@Regge5]

more like the line between falling and patachuting, and you def did parachuting:)

[@greenglass1638]

Hey ScrapMan quick Tipp I found that treasure island has a better Launch platform on the mountain top than danger island

[@Rbobclips]

Your videos are the best

[@drprzemek9374]

Hello scrapman. A request for you to try to recreate the ‚vespa caproni’ An experimental armoured car with a rombus shaped wheel base. which allowed for a small turning radius.

[@TheyfwMatthew]

You should try making the Navatek UHAC

[@crossbonesxxbeast2128]

Love your videoss keep on scraping

[@SpecialFX99]

Next MP challenge: cannon powered car racing, maybe even cannon steering

[@thenerd4751]

What if you tried to recreate the drill ship from Volcanoids in scrap mechanic that has survivability functions? (Basic working drill, maybe a cook bot to act as a healing station, maybe some mock modules like storage and a craft bot as production modules)

[@austincooper4335]

Scrapman, Kan, and kosmo, and maybe a 4th, should all design 1/3(more or less. Just evenly spread out amongst all participants) of a vehicle and then they have to combine all of them without any major alterations to the individual sections. Can attach them in any order they want. Then race and/or battle each other
