I've seen a few others try this before. The physics engine in this game is surprisingly accurate when it comes to weapon recoil because recoil can only ever get a vehicle as fast as the projectiles speed. (Well until the projectile starts impacting yourself as the speed of the vehicle begins making the projectiles move in the opposite direction, this is why the cannon projectiles explode on you because they subtract the speed of the vehicle from the speed of the projectile. Therefore, untill they add projectiles that break the sound barrier, recoil will never get you past the sound barrier)

[@noonelivesforever]

Basically the Mythbusters cannon from a truck scenario :)

[@drsupergood8978]

What you are saying would be true if the weapons are modelled as air cannons (jet engines). In such a case thrust drops to 0 when vehicle speed and vehicle relative outlet speed become equal because the momentum of air in (stationary) and the momentum of the air out (stationary) are the same so no momentum can be imparted to the vehicle during the process and so no change in speed can occur. Vehicle speed is limited by outlet speed. Real cannons are more like rocket engines. They fire off some amount of the vehicle's mass away from the vehicle. As this mass is already at the speed of the vehicle, and some change in momentum will occur, thrust will always occur in the process. Vehicle speed is not limited by outlet speed. Trailmakers seems to have unlimited ammo, meaning that they are either using air guns, or realistic cannons with magic. Such magic would be that upon reloading or firing some amount of momentum is created by the addition of mass to the vehicle without reduction of vehicle speed.

[@zyeborm]

Rockets can travel faster than their exhaust velocity.

[@azazeldeath]

Just so you know Mat. The reason those drag racing wheels would not work well is a few reasons ill just cover the core. 1. They only go on the back drive wheels. 2. They have pretty high coefficients of expansion and also have alot of twist, try find a top fuel dragster launch to see why we don't use them on street cars. 3. Your basically a jet/turbine powered vehicle as long as your wheels give enough grip for your needs its a balancing act. The same also goes for downforce. The faster you want to go or accelerate the more the balancing act becomes. As an ex mechanic who has built a few racing/drag vehicles amongst others. Including driving them I can say its sadly not just about pure Aerodynamics, weight or even HP.

[@wyattruebush]

The reason the wedges are making it fly is because it's being pushed into the ground then getting flipped over

[@naughtyfoo]

Agreed, a bit too much focus on aerodynamics and not enough on balance, but then, explosives so...

[@talokay848]

Actually it's a glitch with the wheels (cause in contact with a block)

[@Demonslayer20111]

For real... Like what did you think would happen when you put all the thrust so high up instead of ya know mounting them on the sides or something, and cause loss of contact with the rear wheels? Of course it will lose control.

Matt accidentally creating an Orion drive out of cannons…

[@entername1107]

Canons go brrrrrr

[@dimitar4y]

kinda. Orion drive accelerates from the nuke's gas expansion. This is more a mass propulsion, where the acceleration comes from "Pushing away from" a solid mass, rather than gas.

[@dimitar4y]

I think the reason the cannons explode everything is because the vehicle is going so fast, that when the projectile is launched, you drive right through it before it has had a chance to separate away from the vehicle. Essentially in a single game frame, you shoot the projectile, but it's collision is disabled with its firing cannon, and then you drive forward so fast you drive the second cannons into where the first cannon was. So it's like the cannons are pointing into eachother.

[@spacemanspiff8635]

Correct, the vehicle is running into the projectile before the projectile can separate outwards

[@joserene-t5z]

Matt: I'm going to make recoil into propulsion Me: I never thought I'd see a Civil Engineer make a pulse detonation engine. Next thing we know, he'll be making a rotation detonation engine. Me a few minutes later when he used a minigun's recoil for propulsion: I think he just make a rotation detonation engine

[@kraftyfox.2658]

I'd love to see an attempt with the Miniguns, with the Articulated style too. I dunno if that would help or not? Keep up the great work!

[@thattomciccone]

For sure! he needs to put those miniguns on the 45 degree angle. There are no explosions so it should work wonders.

[@YoungGandalf2325]

"If we can fly, then explosions won't be an issue." 😂

[@thechap82]

Matt, you can make your wheels have a wider base so that they're more stable. Remember the thing about triangles.

[@iliketrains3546]

I like how Matt used engineering to not widen the wheelbase of the minigun vehicle

[@Yoshijosh31]

I believe the aerodynamics does work differently in that it's more realistic now. When you swapped the front wedge's orientation, it sucked it to the ground then flew up as the rear wheels were no longer gripping to the ground. I guess they had to make the change in favour of realistic aero for all the airplane stuff.

[@samplename5159]

Acceleration changes the effective angle of cannonballs firing to more steep, it's just not going to work. Perhaps you can get more angle aiming them to the sides and hinging towards the back end. You can also try spacing them out a bit more length-wise, but that will add extra weight. It's probably worth exploring if the minigun glitch works on cannons: 4-5 rows of miniguns with cannons on the back. Really fun one, a bit disappointing we don't have an official speed record yet!

[@Brakerjw]

As an engineer that’s not a civil, the lack of understanding of why bicycle wheels were fastest was so painful to watch unfold. Racing wheels are wide and high friction because they need to grip the road because they are the interface between the car engine and the road. Wheel spin is lost power. When you’re not using the wheels as the source of acceleration, less friction is better. Make no mistake, I couldn’t build a proper bridge but this lack of fundamentals in physics outside stress and strain is why other disciplines of engineers make fun of civils.

[@CrxzyYT]

the award for "Most Destructive Vehicle" goes to... RCE. Just beating an Apache attack helicopter

[@lordgenerias]

I think the miniguns at an angle would be the better option. Less of them, but constant acceleration until they overheat. But it does remove the issues of them destroying the back rows. If cannons are still the choice, a sort of fan might do the job. Wide at the front, narrow at the back. Hinges would still be needed to avoid blowing half the vehicle up from the first shot, but other than that, I think that would work.

[@Jesse-zk9ge]

Hey real engineer, I mentioned this to another guy who was trying to break the sound barrier with the guns. I guess he just didn't borrow the reading light suggestion. One property had is when you line the guns up before another they tend to blow each other up. I had the idea that if you line the guns up on a wedge shape where each row is shooting over the top of the other row, I believe you could essentially Ustick recoil from each row without blowing up the other guns in front of them. Plus if you make the vehicle a teardrop shape with the longest part what's a Gunther range on it might improve aerodynamics.💧 this is why I mean by Teardrop shape I would imagine that the mini guns what shoot wait for the longest end. Too bad you couldn't make actual Brown shapes I would think it would be absolutely awesome if each minigun was arranged in concentric rings with each one being the smaller one within the other.✌

[@arctic_void]

Small tip, use the flat connectors underneath the cockpit going all the way back to connect the miniguns, it'll help apply the force horizontally to the center of mass and stop the vehicle from digging in the ground, which makes it eventually fly out.

[@monstermonster636]

Minigun powered vehicles, that are bright red. You just made an Ork's dream ride. Red Dakka goes fasta, Waaaaaggghhhhhh!!!!

[@duskyrc1373]

I think part of the problem with the camnons may have been due to them still hitting the vehicle even when angled outward. I think the outward speed of the shots was not enough to clear the vehicle before the acceleration pushed the vehicle forward enough that the back collided with them. If that's the case, then angled miniguns (with their higher projectile velocity allowing them to clear the vehicle, plus the grace period they seem to have before hitting your own vehicle) might work.

[@ag4765]

Actually, the explosion itself is the breaking of the sound barrier by the expansion of the air, so you technically break the sound barrier

[@khaaaaaaaaaannn]

The start reminds me of Grand Theft Auto 3, turning the tank turret backwards and constantly firing made it one of the fastest vehicles in the game

[@supraman221989]

Definitely would not want to draft behind this car LOL.

[@AdamSaltFPV]

You were so close Matt! Use the final vehicle chassis, but with the miniguns instead of cannons, also cover the top. Articulate and copy paste.

[@codysimonson6260]

And by giving them a slight delay so it's more consistent

[@MrCipher96]

I might be crazy but I think the front wedge orientation does infact matter, not for drag and topseed obviously but for aerodynamic stability. It seems the front wheels of the car gets pushed down way more when the two front wedges are the same orientation compared to having them the "logic" way.. might be useful for aircraft builds

[@alexmonk]

I was expecting to hear singing "Welcome back to Trailmakers"

[@RylanYakel]

There’s a part in the blocks section it’s called flat connector 1x# and it doesn’t have any affect on your aerodynamics but connects blocks way better than moving a load of stuff up and needing to put more aerodynamics. JSYK

Well done Engineer! You have done an outstanding job! You have showed an amazing aptitude for your craft and really impressed me. Kudos!

[@onedrop2892]

Matt, you were blowing up with the cannons as you were matching the firing velocity of the cannon balls. If your forward speed equals the firing speed, the balls would simply fall to the ground and explode and not really travel backwards much.

[@WJayther]

What if Matt covered only the wheels and not the entire clearance with wedges? Or is it scratching of under-the-hood on the surface that slowed him down? P.S.: Oh, he did it 4x1...

There's a video somewhere in which we can see guys using a cannon to launch tennis balls at 100mph, then launching them again from the back of truck traveling at 100mph in front of a high speed camera, and viewed from the side the tennis ball drops straight down to the ground.

[@taylerporter6049]

You might run into the same issue with the cannons but did you try inverting the delay? As in, the back cannons having zero delay, the second to last having 0.5, and so on?

[@djmintyfreshful]

[@Gamelycan]

Because I didn't see it mentioned yet: The reason the cannon explosions kept getting closer and closer to you is because you were getting closer and closer to their launch speed (which is capped). With the cannons being so close to the ground, the projectiles were just dropping.

[@takumi2023]

i like how you're thinking that it's an aerodynamic issue but in reality it's just leverage issue lol. all your weight is in the front and you have no weight in the back. the sudden acceleration is pushing the car down causing it bounce. and when it bounce back up it takes off. you can solve this by adding guns in the front or to the side of the vehicle.

[@abdiasization]

Could you make the last canon the first to shoot. So that when the first one shoots the vehicle is moving and won't blow up?

[@TheInternetHelpdeskPlays]

The cannon issue is easy. They fire the balls out at 130mph, when you get to 130 they come relative to the forward speed so effectively zero meaning they explode closer then when you are stopped. Because science!

You are fighting physics, the faster the car goes the shorter the path of the cannons because you are countering their velocity with your own, so eventually you are at the same speed that the cannons fire, giving the cannon balls net 0 velocity and causing them to drop straight down destroying the car

Anything projectile based is going to drop the projectile _straight down_ once you are moving at the speed of that projectile. If only the ground wasn't there! lol Check the mythbusters episode where they fire the soccer ball off the back of the moving truck.

[@ThePandaInTheTrash]

This is the 3rd person I've seen try this with cannons. Has no one seen myth busters? They shoot a ball out of a cannon strapped to a pickup truck and match the speed of the shot so that the ball drops straight down. The cannon balls have a set speed at which they leave the cannon. If you match that speed, they drop straight down and explode your vehicle.
