@@GDVilluh that’s quite literally wrong

[@Krysgann1]

Ohhh even better

[@tomasmokrys4635]

There is one improvement that you can make. If you have two wheels, one in the front and one in the back of a vehicle, there is a gap between the two wheels. You can fill the gap not with blocks, but with shields. Shields have a "hitbox" of the size of a normal block for the air, but the real HITbox does not exist. In your case, put 2 by 4 shield blocks on the bottom of the vehicle. It is going to remove the green arrows on the rear wheels.

[@kuwi1061]

But there may be a problem with weight

[@tomasmokrys4635]

I think the improvement could be dramatic because the aerodynamics on the wheels are not the best

[@lamonttang9376]

You could use spoilers since they have a hitbox slightly smaller than a block, plus it’s only .1 kilos

[@tomasmokrys4635]

@@kuwi1061 We have seen in Scrapmans videos that the aerodynamics are way more important than weight. Btw the shield blocks are so light compared to the whole vehicle so there will not be a problem with weight for sure.

Also, that speed might make it lose control as seen with the ski versus compass.

[@Pystro]

@@londonnelson7359 Yes, the single wheel would be half a block off from the center. But didn't he have a gyro stabilizer for both directions?

[@Nariku]

for those who don't understand why it rotates like that with the ski: what's happening is that the power is only coming from the rear right, which is causing a gradual turn to the left; whereas before there was also a wheel on the front left, which balanced the output.

[@quakxy_dukx]

I thought so too at first but it was turning even when stationary

[@circuitgamer7759]

@@quakxy_dukx I'm wondering if it's a similar cause to something I've observed in a few of his other videos. In a few places, if a car lands at an angle so the edge of the tires are on the ground rather than the full bottom surface, the car gets a large force pushing it to the side away from those wheels. I'm wondering if the ski is adding a slight sideways tilt in addition to a slight pitch tilt, causing a significantly reduced version of that behavior.

[@JustWillB]

I think it is because it is falling over to the right and then being pulled back by the gyro. Each time it falls it rotates around an axis between the two contact patches, when it is pulled back it is rotated around the axis of the gyro, which runs down the centre line of the vehicle. These are two different rotation axes so it doesn't quite go back to it's starting point each time this happens. There is a net rotation about a third axis which is the sum of these two rotations. Because the vehicle sits on the ground any component of that rotation which isn't around a vertical axis gets cancelled out, and what we're left with is a slow turn to the left.

[@TheBaldrickk]

I think putting the wheel and ski in-line would help with this

[@SkidrowTheThird]

​Yeah... [at] Nariku is right, but as [at]quakxy_dukx said Trail Makers is also doing something weird too as the creation was drifting while "stationary".

idea 2 is literally just "make a stable aircraft without stabilizing your aircraft" the only method I can think of to do this would be to use the logic scrapman uses for his drones, with a speed sensor that turns on thrusters to stop any movement until you press the key to move that direction. however, you'd need to add them to be able to counteract all 6 degrees of freedom instead of just falling. depending on how complicated you make your logic gates and if there's any overlap between which thrusters handle what motion, that could be up to 24 thrusters with only two for each direction of motion

You could but some shields under the engines. They should not grind on the ground but there hitboxes should prevent the back wheels to have a aerodynamic field

[@mjb7015]

Multiplayer Monday idea: car evolution, but randomly, like actual genetic mutation. So, start with the most bare-bones block on wheels you can make, and then have a bunch of options (extra wheels, suspension, different engines and thrusters, aerodynamic pieces, some really random stuff like weight blocks and ball spawners and so on) on a huge wheel of fortune type thing, and each of you has to spin the wheel to decide what you can add to your car each round. I think it would be fun and a challenge for more experienced builders like yourself.

[@wfuller4986]

Scrap you should ask the devs to make grid map loop

[@DGDUGDG]

If you kept your wheels in-line, you could use the aerodynamic blocking capabilities of shields to block out the aerodynamic inefficiency on the rear wheel!

[@MasterWolfe18]

U should add shields to the botton to get rid of the back wheel arrow

[@Matheus_eckhardt]

One possible improvement is to put shields from the front wheels to the rear wheels, as the shields are aerodynamic, and would prevent having to "take" the drag on the rear wheel, reducing drag in general, but adding weight. therefore it would have lower acceleration due to weight, but higher final speed due to aerodynamics

The numbers we want are definitely in the background somewhere, we just wanna see them :)

[@ledocteur7701]

Dissapointed you didn't give the recessed skies a try, because it actually works, the skies hitbox is a about 1/3 of a block lower than it's visual bottom. I don't think it would be practical for engine powered vehicles, but for thrusters powered vehicles it's a huge improvement, so keep that in mind if you ever revisit some of your older thruster sound barrier videos.

[@FoxDog1080]

Since the ski works when it's covered, you can cover two skis on the front with 4x1 wedges It'll make your drag profile bigger BUT it might help with rotational stability

I think this would be an interesting challenge due to the need to balance aero, acceleration and the power limit. - Yes I will try on the discord, but I cant be bothered, and I'm stubborn, so I will try this method for 1 month and then start on discord.

[@XXXTENTACION43V3R]

If you want less aerodynamic drag put 2x4 shields on the bottom of the vehicle basically cancelling out aerodynamics through the underside

[@VroomNDoom2602]

Hey, Scrapman, Turn your nose wedge inside-out so that there is a pocket in the middle. You can then add connectors from the side of your wheel to the wedges. Realistically, it seems like this would make an air pocket, but I don't think the game works that way. If you need to connect the left and right wedges together, just add a connector on the top or bottom.

[@159asmos]

26 i was really close without the new tricks. isn't the benefit of the ski that the hitbox extend slightly below so you can have it flat with the bottom without drag? what if you have a ski and a wheel on the front and back flat with the bottom? does that extra few pixels bring the wheel off the ground?

[@vladimirputin3426]

Hey scrapman, just a few things of note about engines and the test map. Firstly, I suspect that the test map is actually *rectangular* , hence why the compass creation wasn't very accurate. Another piece of evidence for this is your perfect corner-to-corner run during the RAW engine test. You were clearly off-line due to the checkered pattern appearing to scroll, but you still perfectly went from corner to corner in a straight line. This is possible if the map is wider than it is long or vice versa. Secondly, two wheels is likely to be the most optimal setup for engine tests. I think that the engines in TM work by dividing the total engine power across the number of wheels, with the benefit of more wheels being better traction and acceleration while trading off top speed. In the case of the RAW engine test, having more wheels may have been beneficial due to you having top speed to spare and not enough acceleration to get to it. Likewise, dragon engines only need two wheels thanks to their high acceleration and top speed, meaning that it's best to keep the wheel count to a minimum to maintain the best top speed potential. Finally, if you're trying to remove wheels from the engines while maintaining rollers for stability, *you can disconnect wheels from engines, much like how scrap mechanic bearings work* . select the engine cluster, open configuration and simply untick the wheels you wish to keep unpowered. this takes them off of engine duty without the burden of actually removing wheels from the craft. Great video as always, looking forward to the next one!

Scrapman, I have a suggestion, please reply if you have any feedback. What if you used a gyro to make a monowheel and reduce the air drag. Also revisit other seats to see if you can reduce the hitbox, and try different orientations of the seat. Perhaps put 4x1 wedges in front of the wheels for better air drag. Perhaps use a piston and detatcher to accelerate the seat at the last second you break the sound barrier. Little bit cheats, but might work.

16:04 Before I watch the rest rq, I think skis are a bad idea for speed because of the higher (stationary) surface area being 'dragged across' instead of 'rolling on'. Theoretically, it would work if you can adjust the friction settings of the skis themselves...but then again that would increase the 'slide' side effect. As far as balance goes put wedges on your sides and get rid of the gyro. That would also help with the aerodynamics...and maybe even weight.

This might indirectly prove skis are better than wheels for thruster-based creations. Eventually you went to just skidding on the creations' underside for rocket sleds, I wonder if skis beat that. Intuitively I think they should. The outsized effect of dropping from four wheels to two might be due to rolling ground friction as well as aerodynamics. Which also makes me think: would adding a gyro stabilizer for pitch let you create a supersonic unicycle?
