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.

[@ledocteur7701]

I just tested it, and it's not worth it, however, I did find that putting 2 flat connectors at the bottom to act as contact surface helps significantly, not enough to do it with 3 tail propellers, but it significantly lowers ground friction without affecting aerodynamics.

[@loganroman5306]

Irl physics suggests that adding more drag would easily outweigh it because drag is speed dependent, while friction is constant.

[@edopronk1303]

IT'S POSSIBLE WITH THREE! With skis! If you lift your gokart seat one block, put 2 skis there, and put two skis behind the tail propellers, so, not under it, you get the friction reduction from the skis without extra drag! It worked with the dragon thrusters, then I bought the dlc just to try this out with the tail propellers.

[@edopronk1303]

Also, instead of the skis, with a hoverblock, gyro stabilisers and powered tailfins😁 Still no 2 propeller.

[@buckduane1991]

Not sure if you’ve thought of this or not: but you have mentioned how you start in the middle of the map, right? -So by starting at a wall as you sometimes do, you get twice the distance, yes? -but have you realized that the map is a square? If you start in a corner at a 45 degree angle, you will have even more traveling distance available to you going a diagonal NE to SW (C) than you do horizontal E to W (A) / vertical N to S (B) as a result. You’re basically turning the square into a right triangle. A^2 + B^2 = C^2, you know. If you ever need those few extra seconds, corner-to-corner is how you can get that! You could literally revisit your “if I only had a few more seconds” builds now and get your “what if?”!

[@outandabout259]

I'm pretty sure he knows that and has tried it before when he needed more space to accelerate. This time the top speed was reached or sound barrier broken before he hit the wall so there was no need to go corner to corner.

[@BatroSkywatcher]

I know acceleration does not mean higher max speed but what if the propellers are reversed? Also he should have tried the skis anyways just to see if 3 is achievable

[@raphaelfranzen9623]

I think you have the wrong idea there. It's easier to slow down , because the drag also slows you down..

[@Crazyclay78YT]

[@dermanager1671]

Sound barrier videos are what I live for

[@aaronp51mustang]

A helpful easy tip for these test. Instead of going side to side, go corner to corner in a diagonal line, you'll have more room

[@lubbelstengsel9607]

Things that could make it better: friction reduction: Skies, make the wedge touching the ground go up to make the frictionprofile slightly smaller. I think you were onto something with making the craft lighter to the ground, aerodynamics on angles combined with seatsteering could possibly work. What if you placed a flatconnector on every corner on the botten? Would that be enough to lift up the belly of the craft from the ground? Could you have used accessories as skies since they dont have any aerodynamics? Or possibly have a detachable set of wheels to help you accelerate faster in the beguining? Additionally if that isnt enough you could hold it in place at the start and let the engines ramp up before detaching it from the ground. Starting at the very corner of the map on a 45 degrees would also give you a tiny bit more room… What happens if you put the propellers at (-1.00) speed? Since pistons have a faster maxspeed at (-100) than 100. There is always room for improvements.

[@humphrey2754]

It would be cool to do a battle where everyone starts a fresh campaign and they have an hour to collect as many parts as possible, then you do a battle only using the components you founds.

bro i love scrapman's content it is always entertaining and fun to watch, keep up the great work.(btw i am subscribed)

[@chasemittl8729]

Focusing the center of mass above the center of thrust could cause the thrust to provide a slight torsional force around the center of mass that would try to lift the front, but less than the flipped wedges did. Even a slight upward angle should pretty significantly reduce friction with that amount of thrust/speed.

[@TodayTheFlash]

I very much like your thinking! But sadly it doesn’t work, I’ve tried putting the seat behind the thrusters and added skis aswell but could only reach 1190km/h, however I have found a way to do it with 3, you just got to add a gimbal jet to the centre but I don’t know if it’s considered fair by what scrapman uses

[@chasemittl8729]

@@TodayTheFlash Thanks for testing it and giving the nice response. I didn't personally test it with this build so I didn't really know if it would work or not, but I feel like I have observed some changes in automatic pitching depending on the vertical placement of the center of mass in relation to the center of thrust on a jet I made, but regardless of whether or not it is actually accounted for in the game, there are far more variables to keep track of with a jet that moves through the air instead of along the ground. A gyro that stabilizes it to angle slightly upward should also do the trick, but like you said with the gimbal jet, it might be considered cheating by scrapman's standards when testing these things.

[@MrGaleor]

Hey, Something I don't think I've ever seen outside of a few workshop hunts is the idea of a corkscrew aircraft. But jet propelled

[@nohax3691]

friction rn: bro please fix me scrapman: *doesnt even remember about friction on the ground*

[@Gnordlan]

I would have liked to see you try skis regardless, just to confirm. They have really helped in some of your other creation test videos.

[@phillipscott7582]

I think the thrust that doesn't have power ratings are ones that gradually build up speed where the ones with a rating just have an instant flat speed.

[@itsaqualight]

After watching your melee only dog fighting video and seeing your power coupling strategy, I had the idea of a jousting challenge using the couplings due to their destructive power ability to absorb kinetic energy. You could do it with cars or planes but a submarine one would definitely be interesting.

[@huey2026]

I freaking love the sound barrier vids.

[@commongaming4797]

It is a little cheaty but, if you were to replace the aerodynamic wedges and replace some with 4x1 and 2x1 flat connectors. Then fill the blocks in behind the with gridblocks would the flat connector make the gridblocks aerodynamics equal 0. If it works it would kinda be cheating the system but I think in the name of science it should be tested. Thank for your time Srcapman as well as the enjoyment you have brought me over the last 4 years.

[@knightbeforedawn]

It's probably been suggested already, but what if you used 2 lift slopes in the front and 2 in back to generate lift in both the front and back? This might make the flight more stable for just long enough to allow the sound barrier to be broken before losing control. Side view diagram: (very rudimentary) [Aslope][...B..][p][p][p] [Aslope][Seat][p][p][p][B] [Lslope][Seat][p][p][p][Lslope] Aslope = sideways aerodynamic slope Lslope = lift slope P = Propeller B = block Seat = seat

[@TinaGloria2012]

I'm wondering if you use a light seat, one fan in front and two in the back because of the great aerodynamics of the propeller itself. Should work better I would guess

[@favorites8651]

For the wedges on the front, you could reduce the number of pieces by having two triangles next to each other. \/\/ Instead of \\// which doesnt attach

Can't belive you didn't try adding skies or wheels as you did that every other time.

[@Dragoneer17]

Last time he removed the wheels because it was just as efficient without them, and the creation was pretty much touching the ground with aerodynamics. Although the skis would have been cool to test

[@KurzhaarBard]

Yes, last time he didn't use wheels at the end (space thrusters)@@Dragoneer17 but afterwards he tested it with jet turbines again and with wheels they were faster. Ofc it is still possible he tested it prior to making the vid.

[@robertdemare6140]

hey, u can fit hover pads and a gyro stabalizer to remove friction on the ground behind the propellers

[@robertdemare6140]

i tested it, actually can do 3 scrap. only took 6 hover pads lol, but completely glitchless (AFAIK)

[@pularis1629]

13:25 You could rotate them so they make a v. also, you have an extra small grid block that while yes, will barely affect it, it still will slow it down

[@Nomiswelt]

Maybe rotating the lowest wedges in the front upwards (and cancelling out the lift with downwards wedges at the top) would reduce ground friction enough to be able to do it with three

[@randomaccount-rw3bm]

You need to add aerodynamic pieces in the back it actually affects the drag in game, you can also put the flat connectors under the vehicle to reduce friction

[@evesing1281]

Tail Propellers can also be used instead of gimbals in cars for maximum downforce. They weight way more and have more power. The only issue is that these are quiet huge.

[@DeathmetalChad]

One phrase: Try to add skis and upside down 4x1 wedge. Counter on top with 4x1 normal wedge. Probably will work.

[@andreamarchetti1010]

Hey scrapman, did you try to break the sound barrier with only aerodynamics pieces and gravity? You should see how much weight it need to break the sound barrier

[@doublefoxww3658]

You could try breaking the sound barrier using hover pads with the tail propellers in order to eliminate friction

[@calebr8245]

I am curious about friction. Skiis have a fairly good aerodynamic profile. I wonder if the friction of the vehicle is greater than the drag of the ski. If so, that might be the push needed to get 3 fans to work.

[@-n3rv1o43]

You should use wedges to make your build lighter, but since what a moment you did forget about gyro stabilizers? You also had some extra space for them ontop seat and behind creation. And someone also mentioned about skis under seat (while not ruining profile), by combining all of that, you may evene beat with 2 tail propellers imo. At the same moment, this is not cheating or bug, cause this is the part of game ^_^

[@Helix142]

had a idea can you use power couplers to make some type of whip that could possibly break the sound barrier?

[@AlrenClan]

I’d love to see this series but how slowly you could go with the most engines, but also trying to have as few power cores as possible ( excluding the engines ), so you can’t use any quantum rudders or engines facing the other way, all of your engines have to be facing the same way and you can’t use any non engine power cores.

[@user-gh5vp6vh7j]

The top wedges can attach in the center without an extra block

[@Psycorde]

That was trippy, it looked like you were going sideways on the first speed test

[@allengrove1864]

Now you should try to see how few power cores hare needed to break the sound barrier

[@nateforlife]

11:53 / 19:54 For editor: deceleration is mostly mesured in negative G force bacause you would feel the opposite of the G to accelerate, in other words you get pushed foreward.

[@myfriendtata6386]

The way skis lose all friction is because the have a tiny thin layer of air so adding aerodynamics wouldn’t drag on the ground

[@biohazard_the_potato_muncher]

I wonder if hover pads could help, it adds a lot of air resistance but it also completely nullifies friction

[@karamkaram6197]

You should put a hover block in the back just one and a gyro stabilizer at full strength so you don't need to change a lot of aerodynamics 😊

[@net-koen]

Could you build a plane using only wedges for the lift? Keep up the good videos:)

[@cydtron7.081]

You should make a fighter jet style build that can actually go Mach with the tail propellers

[@ferncancersong]

If putting 1 in the gimbal jet makes it go upwards and -1 makes it go downward just put in √-1 to make it go forward😊

[@DoritoMan177]

He should have flipped the trailing edges, they were causing so much friction, but it didn’t actually go TOO much slower! Imagine the speed difference!

[@Reeck]

there should be a vertical tail so that it goes perfectly straight since you can see that the vehicle is kinda travelling sideways which makes the aerodinamics worse

[@GregDittman]

Since we know the connector bars don't add aerodynamics (or at least they appear not to) could you add wheels in-line with the vehicle so that it's cross sectional area won't change but you'd reduce ground friction?

[@rccookie6202]

Facing some wedges downwards to create lift didn’t work, but what if the they were at the center of mass instead of in front? My idea would be to extend some of the front artificially to more the center of mass forwards. This could create actual lift without flipping the vehicle
