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.

POWER COUPLERS! sorry it’s a habit.

[@changjared2600]

in case anyone doesn’t know, irl helicopter’s blades are allowed to flop around slightly, this helps reduce the rolling force subject to the rotor from the helicopter moving forward due to a difference in the speed of the air flowing over the blades on either sides of the helicopter

[@dylandebruyn356]

Isn't this also the case for planes? I know plane wings bend a little too but i'm unsure if it's for the same reason.

[@bungeetoons]

Yes, some plane wings bend(or really flex). I dont know if theres an engineering reason like the one for helicopters. If I had to guess, in some designs, having the wings flex upward slightly, may have been within the acceptable range of structural support, rigidity and flexibility, while also, maybe, adding some minor stability in flight.

[@changjared2600]

@@dylandebruyn356 yes, plane wings flex, for different reasons for different types of plane. earliest planes bend their wings to achieve aerial control while modern airliners allow their wings to bend to dampen turbulence and other vibrations. modern airliner’s wings can actually bend quite a lot.

It's only a matter of time until Scrapman tries to break the sound barrier with a power coupler plane. And, lemme tell you, trying to do so gets real weird real quick, lol

[@Echo_the_half_glitch]

He's already broken the sound barrier with power couplers because of it spaghettifying itself.

[@Echo_the_half_glitch]

But I agree, and that would be pretty cool to see.

[@Loop_Kat]

@@Echo_the_half_glitch Yeah, spaghettification is an easy means of accidentally doing so, but I meant breaking the sound barrier with a vehicle intentionally designed for it. I tried it myself before posting a comment and, while it's definitely possible, it presents some interesting design challenges if you want to keep the coupling-joined wings from spazzing out at those speeds

[@ameerzuher5347]

Video Idea: Make a plane with power couplers and make it so that the only way to control it is to bend the body parts of the plane using hinges that attached to the power couplers. So it looks like a chinese dragon

[@Raider_Gaming422]

I support this

[@bungeetoons]

That does sound like a cool ornithopter.

[@AlrenClan]

I’d love to see some dogfights where instead of being limited functionally, the limits are aesthetic. Such as, you have to build a chinook ( with a basic power core / block limit ) or you have to build a tri-plane, it would be really interesting to see how different people build these different vehicles differently. ( I explained this in a lot more detail in the video ideas discord channel )

[@Hadeks_Marow]

Hi scrapman, here to explain game physics again: When parts are welded/glued together, they are treated as a single physics object. HOWEVER, when they are detached via a rope-like joint, they are a separate physics object (similar in nature to the tractor beam thing). Because of this, when you detach wing parts, the force those wing parts isn't being applied to the whole creation, rather just everything that it's directly attached to (where in this case, the laser string is considered "indirect attachment") This explains why you spun out when you detached the top blades from the bottom. This is because the counter torque does not apply between separate physics instances, even when indirectly linked. It also would explain why the wings went up when you slowed the engines down. . . because the upforce of the wings. . . were only being applied to the wings themselves and not the main body. Where wings, by their very nature of being wings, are very light and don't need alot of speed to lift up, if the only thing they have to lift is just the weight of it's own wing'ed self. You can test this analysis by reproducing the top/bottom separation. . . but putting laser string between the bottom blade and the helicopter rotatee part.

[@coreytaggart128]

Challenge idea: functional parts and couplers only. must have a coupler between any functional blocks. Then after each round the stiffness is decreases. could be a race challenge or combat.

[@plaindumbvariety8403]

I really appreciate the new editor. They've been here for a while, and its been great. They obviously care for scrap man and his audience. They go out of their way to explain complex concepts in simple ways to make content more engaging. Past that they provide a wonderful viewing experience, all the little things they do stand out. We love you, editor.

[@AnthonyantARBY]

I love the explanations the editor gives on why things happen. as well as the brief few seconds of metal music when the power couplers go crazy. makes me chuckle every time. Great job, Editor!

[@Hen3349]

Having the blades droop like that is actually really realistic since helicopter blades do flex and droop irl

Would love to see the devs add a switch to the power coupler. Imagine the endless possibilities for multiplayer mayhem!

[@ThatOneHeather]

The detailed explanations were very cool, it could be a fun segment in future videos

[@justalilguy64]

theoretically you could to the traditional opposing stacked blades with flappy bits if you alternate which segments are power couplers, like the top set of blades could go blade + coupling + blade , and the bottom set of blades could go coupling + blade + coupling, since power coupling don't have collision on their body this might fix the whole spaget issue.

7:52 A froglike swimmer/boat thing, using how a frog would swim with its back lags as propulsion would be neat to try

[@ferininemailestrom5219]

Scrapman. You may or may not be aware of this, wings in trailmakers only apply down force when flipped. Reversing the direction so the down edge is forward still gives lift for some reason, i believe that is part of why pitching forward was so bad, the closer blade to the center of mass is momentarily getting more lift as its closer to the center of rotation

[@JossOwX]

This is the scariest scrapman video for some reason

[@zompigeon6608]

The 3d animations in your latest videos just looks so professional 👍

[@Aussie_Man]

It would’ve been so much smoother, if you transformed the plane into a helicopter as you Sid it in the intro

[@Alpha.Phenix]

Look at it this way: You may have ''failed'' at creating a helicopter, but you did succeed at creating a new type of ''land''mine which cuts everything to ribbons.

[@ClipThat69]

If you've ever seen those 3D screens that use a rotating blade with LED's. The LED's constantly change colour forming a picture as it spins. You could potentially create patterns with the power couplings with a lot of logic and syncing. Could be an interesting idea if it could work.

[@buckduane1991]

I think an ornithopter dogfight using the power couplings to make the wings would be new and interesting.

[@dylanhobbs372]

Multi-player challenge: to build drag cars and after each race extend areas of the cars by one powercopling, placement and stiffness chosen by the previous race winner.

[@final_catalyst]

So with power couplers, you can put them side by side or on top of each other to make the bend mostly in only one direction. Side by side and they mostly can only flex up and down. Stacked on top of each other and it mostly only does right and left. If you make a difference in strength you can effect the motion to be twisting or greater in one direction and less in the other

[@final_catalyst]

The effect is great the longer(more) couplers

[@snackgangsmokey]

We need more crash landers…love u

[@themultichannel77574]

[@HarrisonBennett-ps4pd]

new battle idea. Floppy Guns: A tank battle but all the guns are mounted to power couplings.

[@Jack_Wolfe]

11:55 you also have to remember the couplings are increasing the length of the parts, which will mess with the stability.

[@BunMoony]

"It's working, it's working, and yah shouldn't be a proble..." *Helecopter goes BRBRBRBRBRBRBRRBRBRBR* I spat out my chips seeing it.

[@RamadaArtist]

Okay so after your floppy plane video I went and immediately built a floppy helicopter. And the part at 7:11 didn't make ANY sense to me, because I didn't run into any of the problems you're having with the blades flexing into each other during pitch and roll maneuvers. And I couldn't figure out why until I realized that we built our flight mechanisms entirely differently. I used a swashplate under the main pair of helicopter rotors, (made simply out of a pair of large driving hinges and then another pair of large driving hinges immediately above it and rotated 90°.) I added a couple of gyro stabilizers to keep the body of the helicopter mostly upright, and then added a pair of horizontal gyros right next to the main rotor assembly to give some extra yaw control. With this arrangement, the moment of precession seemingly doesn't cause nearly as much interaction between the flexing blades. I haven't slept enough in the past few days to be able to sort out why right now, but I think it has to do with how and in what direction and everything that the forces are being transferred from the stator body of the helicopter itself to the rotating bodies of the blades.

[@jordanspurou8821]

I want a multiplayer fight with this

[@NyetJustSomeGuy]

I got an idea. I think you should try the parachute thing you did a couple years ago but with power coupler for rope to see how it varies to the solid rope that was used before😁

[@thesleepingone]

Increase distance from bottom set of blades to the body as well. Less likely for blades to catch on the body. Then if you put power couplers there too it might absorb the torque a little in the others direction equaling it out.
