Engineering a HYPERSONIC JETPACK was a huge mistake...

We're back in Trailmakers and this time we're trying to make the worlds fastest jetpack! Can I engineer a hetpack that can travel faster than the speed of sound? Engineering a supersonic jetpack in Trailmakers!

So basically a rocket with a tiny cockpit. You are on your way to space good sir.

Can't wait for the super sonic space speed record

[@michaelchen695]

@@samherriot2617 You realize the speed of sound in space is zero right? If you are moving at all, you are supersonic

As opposed to the UK space agency... 🤣

Makes a mech. Turns it into a rocket. Matt: Is this a jetpack?

[@SallinKari]

More of an Iron Man suit then a jetpack I feel.

[@vnd5160]

"if it has wings, it's a plane" "if it has thruster, it's a jetpack"

[@Nick-hi9gx]

@tristan wienen If you are like duct taped to the outside of it, yes it is a jetpack.

[@monad_tcp]

@@Nick-hi9gx that's a good way of defining it

[@Catraaa]

What is a jetpack but a rocket you strap a person to?

[@spiderwebber32]

If you use or logigates, you can program your multiple controls into one set up. I believe thatdomguy has a video on logic for trailmakers.

[@robertosinjolu2931]

I don't know how he doesn't know that

[@robertosinjolu2931]

Architect vibes

[@vaihacky]

Goal: make a supersonic jetpack RCE: we are building a frickin open plan rocket

[@smilemore1997]

Matt, this isn't a jet pack.. you basically strapped the guy to a giant rocket.

[@JohnCooper-gm6mn]

Matt, you were so close trying to figure out how to make the jets turn you properly. Instead of using two servos on each engine with matching controls, you give them a single servo with independent controls. You also don't need to reduce the angle the engines fire at for a spin, quite the opposite actually. The closer the angle is to 90°, the tighter the spin will be. By reducing the angle, the engines are giving more of their thrust towards increasing your altitude, rather than changing your direction. Left engine forward = W Left engine back = S Right engine forward = E Right engine back = D Then, when you want to fly forwards press S&D, to fly backwards it's W&E. To rotate right press S&E, to rotate left it's W&D. This method also gives you the ability to do a sort of banking arc, left or right, forwards and backwards, by just firing one engine at a time. Happy Engineering 😊

[@suther2]

“So close trying” Pat pats for Matt😂

[@josephmatla1743]

.... Way too complicated for mat.... 😂🤣

[@luthva]

its easier to use a logic block too route the secondary inputs through

[@renascitur7051]

Pretty sure he was trying to increase the controllability of the turning rather than just spiraling out of control.

[@maigepresents5840]

You should apply to the UK space agency... they are still trying to figure out how to get basic rockets into space. 🤣

[@Johan-kk1sh]

People usually try to break the sound barrier.Matt tries to blow it up

[@DatGuy_83]

I love that RCE basically immediately made a knob version of MODOK

[@abqc8498]

3:08 Imagine if you make a Wheelchair that breaks the sound barrier. That would be a great video.

[@link_team3855]

Dont encourage him...

[@CptMaistro]

I'm just amazed at how, when RCE builds something, it just naturally takes on the strongest shape. Is it a gift, or has he just programmed himself so that always happens when he builds? 🤔

[@GR.455]

Matt: calls it a jetpack. me: man thats no jetpack thats a rocket chair

[@T1Camp]

I broke my arm yesterday and your videos keep me entertained in this boring hospital... thank you RCE

[@jacksonstarky8288]

Okay. The video title promised a *hypersonic* jetpack. We got a *supersonic* jetpack. I think Matt owes us a hypersonic jetpack... although I don't think it would meet the definition of "jetpack"... which was already being stretched substantially by the supersonic contraption... which was, admittedly, an amazing piece of engineering.

[@wolfgangbuttner5909]

The air speed record without glitches is 16.000!!!!

[@mikokamin2586]

Oh what a nice rocket you created.

[@padraicbrazeau5251]

“You can have negative speed, what does negative speed do” hahaha love it

[@duskyrc1373]

To be fair, strictly speaking negative speed isn't a thing. Since speed is just magnitude, not direction. Velocity can be negative.

[@pequenoZero]

Just for future reference, you can use Logic blocks (or, and and such), which takes input, and then connect them to the other blocks to serve as multiple inputs to the same blocks.

[@twisted_spirit6223]

So in trailmakers for flying vehicles for pitch and roll you can use helicopter engines without blades to pitch and roll because they create torque so that’s how you can pitch and roll without using thrusters and servos

[@firesidestories5714]

Surprised you didnt add stabilizer engines at the bottom for the strongest most efficient form for the jet pack

[@Music7Ada]

RCE becomes a Sonic fan when he plays Trailmakers "What's your favorite song?" "Sonic Boom" "What's your favorite show?" "Sonic Boom" "What's your life's moto?" "Gotta go fast."

[@tjones1702]

How about a submarine in a boat in a large truck in a plane

[@moroblizniak4457]

4:06 Yes you can! All you have to is use AND logic gate. Extremley easy, barley an inconvinience. Im suprised you didn't know that after this many crazy vehicles.

[@Ifx-]

Yo I love these trailmakers videos!

[@meneermankepoot]

3:08 can confirm this is what my wheelchair looks like

[@RionPlaysTV]

13:26 That's no longer a Jetpack He's made a Rocket lol

[@Falcon-_-]

Love Trailmakers (But only when others play it, too complicated for me)

[@alepaz1099]

"The top is all the way up there so, I have to [use a] jetpack yo get into the jetpack" got it 😑 😂🤣😂 Cheers mate

[@h3b3og84]

Please please make a space engineers series! It even has engineer in the name

[@nyafu_uwu]

you can use a logic gate to have multiple controlls for the servos

[@Tminus89]

Oh man that spinal compression on take off looks fun!

[@valecasini]

Lmao the Ironman citations at the start made me roll 😆🤣

[@UBAT128]

Sonic Boom Idea: Build a "rocket" that has a LOT of mass under it. Go to height limit. Get rid of the thrusters. Fall Down due to gravity. Sonic Boom because of free fall speed

[@cubboard98]

13:59 The exact moment it became over-engineered, when Matt needed to use a second jetpack to get into his 'jetpack'

[@Greg1096]

This is hilarious since you can break the sound barrier with only 4 gimbals a seat and some aero bits

[@tempestarashi5682]

Only a minute and already with the Iron Man references, don’t know what I expected.

[@epicgamez9266]

Oh goodness Matt, you really have outdone yourself again

[@smae5275]

You can add multiple controls to servos using an XOR/OR logic gate!

[@dravenlamb680]

Wow two iron man clips in a row and from different movies no less

[@bharatidalai8938]

Always waiting for your video at this time. You doing great.

That looks more like a rocket than a jetpack

"Negative Benefits" -RCE

[@D_Danya_D]

Hi! RCE, there is a guy on YT named Atomic Gaming (it’s not an add!!!), who got a new video where he built great city in Timberborn game. He said, that he’ll build The Strongest Shape Megabuild if you react to his video) We are all waiting😂

[@hornyrhino9874]

your amazing thanks for these vids

[@kekskrieger4463]

Honestly this game would be awesome to try a giant mecha

[@piotrk1584]

Challange RCE ! Build a super sonic build that’s not a bunch of jets attached to a seat

[@masonhunter2748]

Try the airport expansion. It came out yesterday. you can also see the center of forces try breaking the blimp speed record and yes, you can make blimps now and repair in mid air

[@Paradiso.21]

2:28 Matt, why did you build an electric chair? 🤨

[@progaming-2425]

so it's the try number 2 of telling RCE to play scrap mechanics and build an EFFECINT buildings

[@RedCocoon]

At what point is a jetpack just a regular jet plane?

[@rpgaholic8202]

As soon as you add in extra protection for the guy flying it.

[@MrMan88_]

Woah he said my name 1:38

[@BaeronBubba]

Servo Speed- I presume this reverses the direction when it is negative. (negative clockwise is counterclockwise) So you can have one going forward, and one going backward with no key changes.

[@Read.selppa.backwards]

As a veteran of trailmakers, watching this video hurt my soul

[@JackTheRifter07]

At Like 8:50 all I'm seeing is a Tie Fighter, great video as usual.

[@jeffreyblack666]

You should be able to use logic to control a servo, with multiple inputs feeding into the logic.

[@seyeruoynepotsuj]

I haven't finished watching the video yet but I'll forget to comment: you can give a part different controls by adding an AND gate from the logic blocks section. Connect it up to whichever part you want alternate controls for then set the new, desired control.

[@SonGoku-yw5tr]

“Is it a bird?” “Is it a plane?” “Is it a shooting star?” “Close but no,it’s a man strapped into a super jet width 1000 thrusters and thinks that it’s a jet pack”

[@jhettblack]

That's a really strong shape you got there

[@griffinbastion]

2 things, you could make the two rockets move independently to get left/right turns, also instead doing forward/backward it's better to do backward/down instead when trying to turn

[@potterprog955]

Love how this guy makes a normal looking piece of tech then makes it a monstrosity

[@jozefpro1475]

RCE you CAN give multiple controls to a engine, you just need to use logic blocks

[@Slikx666]

Next Mat tries to get the strongest shape to break the sound barrier. 🤔

[@SallinKari]

I feel this is less of a jetpack and more a reverse drop pod, for a person getting to something into space from the ground in like a minute flat.

[@monad_tcp]

3:00 Achievements : upside down broken

[@krankerkarpfen]

The wild fever dream for some Mekka-Anime fans. RCE nails it xD

[@tipiletsplay1036]

i know im a bit late but... if you cant toll the joint to have different controlls, but you can set individual angles and speeds, and speed kann be negativ... set 1 joint to rotate 10 and the other to -10 :) lets say its 10 degree per second in the given direction, the other should move -10 in the same, meaning 10 in the opposite direction :)

[@michaelmurray2595]

Matt, you're an engineer? Rotation thrusters.... Hey, it's the world's fastest flying office block :)

[@erikcarlsen2179]

Starts out as a jetpack and turns into an all out jet lmao.

[@sebastianacacia7621]

11:00 RCE: ⚡️UNLIMITED POWAH!!! ⚡️

[@nameless5413]

*Space kraken notices someone doing KSP stuff outsside KSP and visits* Jetpack? thats just engines straped to seat with very frightened kerb- person inside, in short its great

[@mathewhawse8858]

Absolutely love the content! Keep up the hard work! Please try the game Satisfactory, to me its kinda like a first person infraspace, but instead of cars you got super highways made out of conveyor belts.

[@_IcyCube_]

Really you could also use different buttons to rotate each rotor like you would do tank controls. If you for example Left side rotor - W forward - S backwards Right side rotor - E forward - D backwards To go forward you'd press W and E, or S and D for backwards, but then you can press S and E to rotate one way, or W and D to rotate another way instead of adding more parts. I also haven't finished the video while typing this comment so if he does do that later in the video and I forget to delete my comment then oops.

[@stickybob5245]

love the content keep it up🙂😁

[@whitetailprince]

matt: im going to make a jet pack. *straps a saturn 5 rocket to the guy.*

[@TheXak662]

12:52 I don't think this is a jetpack. this is just an open concept rocket. very trendy and hip, but not a jetpack lol

[@alphateam6580]

Matt, there should be a setting somewhere to auto-copy the building done on one side to the other

[@patrickharris3296]

You could try adding fins made out of more jets?

Can you imagine? Yes that's what the Apollo astronauts experienced.

[@puksybanda4102]

Scrap mechanic 🥲

[@Map71Vette]

I'm pretty sure that's called a "rocket", not a jetpack, lol.

[@moroblizniak4457]

13:50 Its not pieces. Its complexity. Every normal block is worth one complexity, no matter the size. But moving parts (Hinges pistons etc) cost 5 complexity. Also wheels and skis cost even more complexity.

[@shorttrains]

You could add multiple controls to one servo using and gate switches so the servos won't be a mess

[@UtopssAKAPJ]

He actually did it, what is the next challenge? HYPERSONIC TOILET

[@jacobbowden9936]

I would argue a jet pack requires your feet to be able to touch the ground! Back to the drawing board!!!

[@Im_very_hungry]

fun fact: you can turn a helicopter thing for a really small steering thing, just set keybinds to a and d for it

[@jhettblack]

For multiple comtrols you can use a logic and/or block

[@peterfielding4527]

haha starts off a jet pack ends up a rocket lol

[@rbo_]

yiou can give them multiple controlls you just need logic blocks love the vids :)

[@greenaum]

Having the engine at the top, and the pilot and other gubbins hanging down, so that the thing will be intrinsically stable, "hanging" from it's engine, is a mistake. It's a popular misconception in rocketry. I'm not sure why though, I think I understood it at one point, but that day has passed. As a Civil Engineer you're probably better with static things than dynamic ones, bridges not generally having a thrust to weight ratio. But anyway... engine at the top is unstable, for very important rocket science reasons. How the game implements it's physics, I dunno, but it's wrong. Unless the gimbal jet is just hard-coded for "down" no matter what, but that's not very realistic. What really happens, is that any imbalance gets worse, rather than correcting itself, and the thing nosedives. But again, proper proper rocket science, don't ask me.

[@theodoric4270]

Next up: Supersonic sailboat.

[@thesailsguy]

hello civil engineers and welcome back to 🔄(loading circle thingy)

[@vincentsolus9227]

you could just stack rotors, having 2 in each side, so you put the control for forward and back in one pair and the left/right int the other it may not work well if try push both butttons at same time

[@vincentsolus9227]

oh, he did it some time after lol
