How Few SPACE THRUSTERS Does It Take To Break The Sound Barrier?

Welcome to another episode of Trailmakers! Today I am putting the new space thrusters and rocket engines to the test to see how many of each is needed to reach the speed of sound and break the sound barrier on the test map!

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.

if you get an altitude sensor set to -500m (or a distance sensor set to 0m invert trigger) and set the output to 0.03 and link it to the thruster (or anything which has a ramp up) it will basically just remove the ramp up.

[@meowz0rz562]

the oprator seat, although it may look like a 2x2 from the top, is 3 blocks long, so you'd still have to use 3 stacked wedges to cover it completely when you put it on it's back.

[@adc109]

.01 works too, can't remember but I think .03 outputs visual thrust so I prefer .01

[@dalekelly5617]

​@@adc109ty

[@mayonasepizza]

idk, sounds like an exploit

[@Nevir202]

@@mayonasepizza That's literally how rocket engines work though. They make basically no thrust at very low burn rates, but they have to ramp up. So, IRL you could do something like that' except that the fuel would make such impractical. Since fuel isn't a thing in this game, if there is an "exploit", it's intentionally coded into the game by the devs, meaning that it's not an exploit.

[@JunohProductions]

I think it's the weight difference that allows you to get away with no wheels with the space thrusters. Everything else causes too much friction with the ground.

[@justadam358]

works the same with 2 dragon thrusters

[@bluewhalestudioblenderanim1132]

I Feel like the friction might also be a bit of an issue for some wheel-less designs , if the area of contact with the ground is too big . . but that could pretty easily be fixed with a few wedges

[@--cook--]

it's important to note that, in conjunction with the light weight of the space thrusters, their thrust is perfectly centered. with the large jet engines, there's the heavier weight to consider, but also the friction that is being added against the ground. because the off-center thrust works like a lever, pushing scrapman's sled into the ground with greater force than with the space thrusters, his speed is reduced.

[@TlalocTemporal]

I thought the same, if one jet was mounted upside down it would probably work. Of course that would require the flat connectors being the new point-on-contact on the ground, but maybe that could help? Like little dragless skis.

[@cryolitegem]

@@TlalocTemporalUnfortunately I think the connection points and the hitbox of the large jet engine make flat connectors unusable. Or if they can be use, they would do more harm than good with the extra blocks needed to make them work.

[@calig1236]

@@TlalocTemporal how about putting the jets on either side, it would probably require more aerodynamics, but that would even the thrust

[@TheFrozenKoroNeko]

If you have an even number could alternate left/right or up/down to have tthem cancel out

[@goldragon2543]

You could do a multiplayer battle between vessels that have to fight on the first round on the sea and then in the second round in space, without modifications between rounds.

[@mrnaris4852]

10:14 That was the most big brain yet smooth brained moment i've seen in this channel. Removing the 2x4 block underneath the seat was the right choice... *but you didn't have to replace the seat* The gokart seat has atatchments on the front of it.

I discovered a ‘planet detector’ in the form of the attitude sensor, basically i just set it to the max value and then trigger below. I would love to see you build something using this type of thing. Maybe like a VTOL thing

[@switch2282]

MISSED DETAIL! The large jet engine build when he removed the wheels and aero has 2 blocks down in the corners of the engines with no aero. May have been why he couldnt reach the sound barrier. At 13:00 you can see a yellow arrow. I know he kinda fixed it later but that may have been why.

[@ezra5154]

The editor is the best editor I’ve ever seen, he converted the kph to mph and calculated the Gs

[@catana3179]

I think the mass is important if you don't use wheels cuz friction is bigger

[@CorsaMaster]

Mass only affects acceleration. You don't need wheels because the test ground has 0 friction

[@solana2301]

damn... this is just wow! those thrusters are so powerful, some could say even too powerful.

[@Typicalrn10]

i was guessing 6 for the small thruster and 2 for the big ones but didn't expect 2 small thrusters to do the job

[@slayderplays2623]

Yo, your editor is the goat for all of the side calculations. Greatly appreciated

[@easygoing4964]

i hope they do the teleportation thingy on this flat map,so we could easily doing things like this without worrying about hitting the wall.

[@Spore_Spawn]

wouldn't work as the edge of the flat plane's geometry would catch on the wheels/ bottom of your creation at teleport causing you to crash or fall below the map depending on how fast you are going.

[@davecommander3958]

Sweet! I guessed 3 space thrusters, mostly cause I know how simple you can make these. Great video!

[@brodygamer83]

This is the man that made me play trailmakers٫ I love him

[@jthunter8529]

Could it be that the thruster is applying torque on your creation causing it to push into the ground when you're using those big engines, whereas the small engines are pushing directly forwards?

[@Anti-Smart]

Those space thrusters are great, I used 8 of 'em to propel a spacecraft with 8 quantum rudders to about 260mph.

[@maxwelljohnson8962]

Hey Scrapman! I had an idea for a really whacky challenge. First, you make a plane with an underbelly turret, and then apply air stabilization technology to float in the air with a massive laser turret. Finally, make the turret positionable to create the ultimate superweapon.

[@edgarviernes2532]

Multiplayer suggestion: do bombers vs defenders but the defenders use emp and the bombers have dynamite in them (in space or not)

[@francenkovcan5211]

reason it worked as well as it did without wheels was because small space thrusters were pushing the build up ever so slightly, which resulted in minimal friction

[@DarktideVtuber]

i once built a giant creation that went ~4K kph an i can say, at extremely high speeds, the flat connectors can have a slight effect on drag.

[@mrnaris4852]

I genuinely guessed "2 or 3" Space rockets for the sound barrier, I guessed that due to the fact that you can break the sound barrier with just 1 dragon jet engine.

[@turteschris3191]

I guessed 10 thrusters as well. Thank you for the videos, your the best!

[@mayonasepizza]

im so happy with the new update, space provides an unparalleled level of freedom when building

[@lstchance87]

I wonder if the space jets give the creation less friction since the were designed for a friction less environment. Like maybe the creators overlooked that aspect and those engines ignore friction when wheels are not present

[@darkfire_17]

Wheels add friction. Friction adds resistance and slows you down. In trailmakers, a sonic sled will be faster than something with wheels

[@MikaeldeMedici]

The editor and his physics thing, I LOVE HIM.

[@captainsnekk]

I think that because the space thruster had so much less contact with the ground, it had much less fristion, therefore only needing one.

[@keremo4885]

Contact area doesn't effect friction Weight does

[@thekiplingcats5595]

Love the videos👍

[@Tree_Bricks]

you could of used the jetpack seat and put it on its side to get a smaller profile for the space thrusters

[@edopronk1303]

I thought, I'll try that. The jetpack seat (operator seat) is 3 long, instead of 2

[@me_go_oof6137]

I feel like you might be able to get better results going vertical because no friction against the ground but ill try it out in a minute

[@arthurorenardeau7231]

but gravity....

[@aidenkyle6627]

You can turn off gravity in the session options

[@user-uy8ww8oz2j]

What you could do is remove the 4x1 and change the cockpit to spacefighter

[@meow7985]

The reason why no wheels was better is because without an engine on the creation they become static objects, and wheels have a lot of friction compared with the blocks.

[@mangomanatee3584]

You should do a 2v2 dogfight but you share a plane. Maybe one could pilot and one fires or a rear gunner maybe? Love your vids.

[@DakkaScrappa]

next multiplayer monday more trailmakers and a capital ship battle

[@wolvenedge6214]

I'd like to see you test what the effect would be of layering your shields. I imagine it would be pretty core-hungry, but a virtually invulnerable shield onion intrigues me.

[@antonschmitz2255]

You removed two wedges that were actually in front of the big normal thruster, it's hitbox is a rectangle. You can see it at 12:59 when you go into build mode.

[@petitloup5059]

scrap, in space you can directly go next to the flying chirpo and they will transmit you a message, the one tat i got said he was patrolling galia 9 so pirate don't invade them again

[@unownuserrr]

I've found you can break the sound barrier with one of the small space thrusters if you use the 0 drag glitch with no wheels

[@itsheks.21]

Let’s just appreciate how much times he puts to translate the measurements and weights

[@vtrm281]

use the Operator Seat on th space thruster vehicle, as it has just 2x2x4 dimensions and than you can lower your aerodynamic profile

[@sterlos1499]

It's due to how many points are on the ground, think of it like this. On small craft like the space thruster one, adding wheels will decrease ground friction by about 6 blocks while adding say another 6 to air friction, but air friction has more of an effect on speed. On a bigger craft, it still only adds 6 to air friction while it will remove like 25 blocks of ground friction.

[@lukasschriefer799]

I made a a sound barrier breaker with one of every thruster and it broke the sound barrier like 50 times in a row!

[@reapzf34r6]

7:07 You should try using a flat connector or shield piece near the wheel to cut the aero and keep ground clearance. Idk if it would improve performance but it’s just an idea

[@RobertJackson-vc9rk]

I didn’t have a guess for the bigger engine but the small ones I paused before your guess and also assumed 10

[@janusverbeek3187]

please do a thrust challange where you do the one thruster but then with the space thruster.

[@himenaaa3565]

i think you could revisit this idea again but with improvment, for the rockets engine, you could using the attachment block and attach it on the grounds, and when the time is right you could release that attachment block using disconnected block? or something, sorry but i dont know the blocks name. it using same principle with rocket launch where is holding the rockets until the power is enough to lift up itself before it launch

[@lunarwaffles7696]

since the flat connectors don't seem to have any aerodynamics could you make a wide "Base" to put skis on? they have almost no friction, tho i guess if they're better then wheels or not depends on if they have more drag

[@meowz0rz562]

Instead of swapping the go kart seat with the cockpit, you could've kept it as you had a 4x2 underneath the seat, thus needing 4 wedges, removing the block would've saved weight. Edit: using grid blocks is also better than using those 1x2 rounded blocks.

[@SPlegendYT]

Such a good video and bro what space thusters are that op just because they are small wth

[@rccookie6202]

You need to revisit the old thrusters now, they have a small profile, too

[@aidenkyle6627]

You can get a longer runway on the test map by going from corner to opposite corner ex: top left to bottom right

[@DoritoMan177]

Correct for both!

[@cryolitegem]

What’s even crazier it that I think the space thruster variant can be made slightly *faster.* 1x2 grid blocks are 0.2 kg lighter than rounded 1x2s. Now I know that a collective 0.4 kg will make next to no difference, but it’s still wild to think that an improvement, however slight, can still be made to what is already such a tiny and efficient design.

[@TinaGloria2012]

Space thrusters shocked me, too. I thought like 8, but 2!?!?!?!? I just can't...... they are really amazing.

[@Shakes__26]

Best vids ever

[@Bigbeansthataregreen]

Tip for aerodynamics in small spaces, use the side of the 1x2 shield block. It has the same aerodynamics and weight as the 1x4 wedge, while being half as long. It also cancels the aerodynamics like other regular blocks. The flat connectors also do not affect aerodynamics at all and the flat side of the shield has the same aerodynamics as a wall. Edit: shield blocks do not have quite as good aerodynamics as the wedge 1x4, but the wedge corner 2x2x1 and potentially the wedge corner 2x2x2. Both are also lighter than the wedge 1x4

[@Bigbeansthataregreen]

Another aerodynamic tip, if you want to fill in a space to remove the aerodynamics of that empty space, use the rounded corner inverted 1x2, being 0.2 kilograms.

[@Bigbeansthataregreen]

I have also made adjustments to your final design for the space thrusters and I managed to get a sonic boom without going from one side of the map to the other.

[@dakodamitchell9046]

so one thing i found out on accident that might help, wheels on their side will be frictionless, im not sure if this is patched though.

[@scrazad1601]

Everyone seems to have forgotten that aerodynamics on the backs of stuff actually also does stuff, even if it's not shown in the game. Maybe it got removed, I'm not really sure either.

[@LuncherXD]

[@SwineKing472]

Same.

[@nicki8731]

13:00 For a single frame, you can see some yellow arrows. I think you deleted two more wedge pieces that you needed to. Please retest :D

[@nicholasyost8400]

it makes a lot of sense removing the wheels as it heavily increases aerodynamics. You should be able to do the same with skis.

[@rickyrotarys1501]

Could try hoverpads to take ground friction out of the equation instead of wheels but center of mass and thrust gonna have to be even

[@ontdekkingszeiler1114]

now you found that wheels don't matter as much, maybe you could retry the dargon yet and pulse jet (forgot the name), and witht he nez propellor hitbox naybe the props as well

[@rocketrider6918]

The profile is part of the difference, but its also the weight difference

[@toughquail]

the reason why you couldn't do it with 2 jet engines with that design was probably because of the jet engines being both at the back and since there collision box is smaller than there hit box it caused your vehicle to angle up slightly which would both cause more friction and a slight loss to your forward velocity. try putting one of the jet engines in front of the cockpit to evenly distribute the weight and see if that will work edit: this would also mean that there would be less blocks touching the ground causing friction

[@agoodname7111]

Good job scrap, now make a ridiculously fast hovercraft

[@DryMexagon]

Try to get a sonic boom with quantum rudders! I have seen multiple videos using quantum rudders as propulsion, but always in space. We know quantum rudders work in atmosphere, so it would be cool to see you try!

[@Lexoka]

Maybe your aero blocks should be oriented so as to generate a bit of lift, and thus reduce friction with the ground.

[@Citadel15]

Imagine modifying the space thrusters version a little bit so that it could actually fly in space with directions. IT WOULD BE SO COOL.

[@mightygreen3364]

I feel like reducing downforce might be extremly important without wheels

[@vincentproulx5527]

hey ScrapMan, you could've just lowered the Kart seat by removing the bottom block instead of putting in a heavier seat (that's the same height!)

[@monkeybob151]

I remember that one time I was messing around in space bound and went 40,000 mph then clipped through a planet

[@danielyung7609]

What about an operator seat facing up for the space thruster? Its 2 by 2 compared to the cockpit, which is 3 by 2.

[@DashiellCampbell]

Video idea: Try to make a sonic boom with a vehicle that has to use one of every type of thruster.

[@jrunsvold7150]

Does aerodynamics on the back of your vehicle make a difference? Like a more teardrop shaped vehicle in trailmakers?

[@Drefar]

use those connectors on top of the jets as skits 2 lines of those are less friction than 4 in line blocks

[@jonathantucker5534]

You should do a giant spaceship multiplayer battle with multiple gun turrets, like a capital ship space battle.

[@martas__]

Just to clarify large jet is designed to have a lot of power (example is the raw engine) and the space thruster is built for speed, but it doesn't have the power of the dragon engine
