- John and I are at it again! This is Part 1 of our newest idea... a launch coaster! We're going to start with a wider gauge track than we've ever used before and a super-powerful electric launch system.
PLEASE SUPPORT OUR PROJECT at www.patreon.com/willpemble
YOU DECIDE how fast this coaster gets done and how fancy it is!
YES, the backyard roller coasters are back!
A kingda ka type coaster?? This is gonna be awesome!
I doubt it'll be that tall but it looks amazing.

BACKYARD COASTER YESSSSSS
The time has come for another coaster. Round 5(?)
I am so stoked for this. Too bad the Mack style track doesn't work.
This Is incredibly Ambitious. I hope there won't be too many issues, because it sounds truly amazing. Also, it'd be cool if the top had was an inverted top hat
Very cool! Can't wait to see how this turns out. An electric launch will be awesome to see.
didn't u make the air launched coaster??
YES!
This is a great idea and I can't wait to see the finished product. The only thing you should consider, is that if the launch fails or is too slow, the launch track needs to also be fitted with brakes incase of a rollback.
It should also be at an angle so the train returns to the station if the launch doesn't activate or the train doesn't leave the launch track
It would be cool to see eddy current brakes on this one.
Maybe you could make a weighted launch like the old Schwarzkopf shuttle coasters. It uses less power but using a heavy weight is difficult. Also a top hat requires lots of speed and expert shaping. Probably a good challenge but maybe an over bank would work better?
top hat is more exciting but is see what u mean
I love this channel especially the backyard coasters
Jeez, a launch coaster. Also, what happened to the barrel roll.
Memes.u Table it failed, it was too rough from what I heard
It was from a video on CZcams it’s from insider
Memes.u Table it was like some kind of documentary on the backyard roller coaster
@ColdplayFan360 RollerCoasterFreak Well I mean, it wasn't even heartlined
The roll was not viable for a human to ride.
Thank you!!
You can build a LIM or LSM Coaster (an launch coaster with linear electric motors) in your backyard even with a house power source. You just need to store the energy. The Rollercoaster "Fluch von Novgorod" in the German "Hansapark" used a huge Flywheel to store the energy needed for a Launch. Now they use Supercaps to store the energy needed.
Ahaha yay love the new ideas and can’t wait for the next video
Thank you, Donovan!
Will Pemble no problem 😎 thx for the reply
Whoohooo finally a launch coasterrr
Will Pemble is a god
If the powered launch doesn’t work out, maybe consider a weight drop system like the original Shwartzkopf shuttle loops, or like catapula at Ai Pioppi (Italian handbuilt amusement park)
Or a hydraulic launch. What I love about the electric launch is that we could manage speed without regard to the weight of the rider. That way, the cart will be going the same speed if it's me (very heavy) riding, or a kid (very light).
We'll see!
Omg omg omg omg freaking out with excitement!!!
Me too!!!
YEEEEEEEEEES!
Incredibly excited for this coaster! I'm glad John is working on this coaster with you, you seem to gel together nicely. Hope there's a lot more in depth videos to come. Good luck!
There's this one person building a launched backyard rolled coaster called Gravity. You should check it out.
Who dislikes a video about a new back yard coaster?
LOVE IT
YES YES YES YES I KNEW IT, LAUNCHCOASTER BABYYY
Yeah they’re back
I’ve been waiting for this for so long!
Just saw that wired vid and I wanted to See more keep it up
YES THERE BACK
Excited!!
Carnt wait for next part of this build I lv ur coaster builds will they are awesome pls keep us posted so we can see it as it develops. Keep up the good work
Kicker wheels or a weight drop catch car system might be the best way of doing a launch.
Cant wait!
Gonna follow this alongside Marble Machine X. Hoping for frequent updates! Good luck Will!
have you seen "Gravity Backyard Rollercoaster" it is (at this point) a 3 part serries (on youtube) of a dude also building a launch coaster in his backyard. only thing is he hasnt uploaded anyting for the last 2 months however for what he has got it looks promesing.
Accelerator is so funnnnn
Oh man, sorry if it's early for suggestions, but whatever vehicle you use should have wings and you could theme the coaster around an airplane carrier...
Finally you made another video love your roller coaster videos
Thanks!
Cool beans
YES
But you already have a 350V DC power system with a great motor and controller, just use that! ;-) (You might think I'm joking, but it'd be fairly simple to machine a remove-able wheel hub attachment to a sprocket or some kind of coupling, and jack it up, and launch it)
Seems like your braking system will have to be even more reliable than your acceleration system, if I'm reading you right. You might consider a copper and supermagnet braking eddy current system, the main advantage in my mind being that it's a passive system, as opposed to an active system of, say, electromagnets.
Look it up on CZcams "SuperMagnetMan Magnet Braking on a Skateboard". Probably would cost a lot.
For safety and staying away from the cable side. The sled cart is risky, and adds lots of areas for things to go wrong that could lead to derailment or injury without a very serious build. Stress aside. Might be best to just stick with a tire drive systems with spring load for tire uplift, chain drive the multi tires along the launch section. tension either underside or both sides of ride veh, run off a 8hp plus dc motor “golf cart motors should be fine) geared for the speed you want to achieve. Other approach why not launch it into the spike forward or backward, goes thru load area (can have the drive motors reverse to gain it additional speed from second pass) into air time hill, then climb turn and into tight course in the wider area, then have it reach second spike , and reverse back thru course basically a boomerang leaving the narrow part of the yard with the most space. Return speed will be tricky to calculate depending on the end of property run element used..
Finally
YEEES
Hype
I'm speechless.....
In a good way, I hope?
@@WillPemble ofcourse! Good luck on the project!
Hey will you should do an entire video where it is just a timelapse of the build while you talk about the struggles and things that you had to make to make it work
yeeeeeeeeah
Hey how do you make the cart and the track and what math do you have to do when you if you make the coaster?
With the speed this has, you will probably need magnetic brakes. Would be cool to see you install a simple drive system on this as some type to prevent the need for the car to be pushed... Possibly just a downhill slope with brakes on it like on old Arrow coasters and wooden coasters?
Call me crazy, but this would be a perfect opportunity to introduce a inversion into your coasters, if you plan on making one large element a large inversion would be cool
I’m pretty sure you’re not crazy.
Maybe I’m the crazy one for not thinking of this from the start!
Wonder if we could do a super fast electric launch into a loop, then over a top hat and back to the start.
Hmmmm 😁
@@WillPemble A inversion could potentially help reduce the breaking force required at the end of the run... Food for thought? Also with a launcher system, you could calibrate it to get just the right amount of "oomph" to get around an inversion, while still being enjoyable. What about a top hat into a loop, using a calibrated launcher?
I see Reduction gears everywhere!
Blunder Man!
Where have you been???
@@WillPemble living the dream and making my ancestors proud!
Im super excited. I cant wait too see the progress. How tall is it going to be?
Make a full loop
The steel store yay
So is it going to be a hydraulic launch or lsm or lim
Do need help with the physics and performance predictions? I can get you in the ballpark if you want to know how the top speed of the cart, and how fast it goes at the top of the hill, given cart weight, rider weight, and hill height. Also, how much acceleration you will need given the acceleration track length. From this, you can know how much energy is needed for your electrical system, and if it's even feasible with house power. The higher you go, the more expensive and complex it will be to support your tower, either by digging down and making a concrete foundation, or providing side struts which will take more room. Working high will have safety issues, so be careful.
How do you plan to dissipate the energy at the end of the ride? If you had a long track, it would slow down gradually, but if the track is short, you're going to have to have a reliable way of slowing the cart down. Something bomb-proof, for safety.
Hi Paul!
It would be fantastic to have you weigh in on this one.
Who wouldn't want an actual rocket scientist on the team!
@@WillPemble This is risky business. I personally think you should do a long coaster (like 1000 feet or more) down a hillside with really nice turns and features, like an alpine coaster.
I don't have a lot of confidence in these numbers, but for what it's worth: Assuming you want to achieve 25 feet in height, with a max 250 pound rider on a 50 pound cart, and an acceleration distance of 25 feet, you'll need to a top speed of 13.6 m/sec (30.42mph), accounting for some drag (10%) and a little speed (1.8m/sec) left on top. You will need to apply 371 pounds of thrust ((less for a lighter rider) for 1.12 seconds to get to that speed in just 25 feet. The upturn track radius will need to be at least 15.5 feet in order to keep the g's below 4. Centripetal load in the upturn would be 1198 pounds. Distributed evenly over 8 wheels would make 150 pounds per wheel. This is all in a spreadsheet, so we can play with the numbers easily. I should probably make a video on my channel explaining the calculations, if that's all right. Treat this as brainstorming for now. I probably made mistakes.
@@WillPemble I ran the numbers againwith 15 ft height, 200 pound rider. The upturn radius to keep under 4 g's is only 9.5 feet.
I added a power calculation, but I don't trust it until someone checks it out. Not my area of expertise.
I tried an acceleration distance of 10 feet, but, If my calculations are correct, that would take 16667 Watts or 22.34 electrical horsepower.
I increased the acceleration distance to 20 feet, and that takes 4167 watts or 5.6 electrical horsepower.
Like I said, I don't remember much about electrical power. Maybe John or another subscriber knows how to calculate the required power.
I made another video investigating a air pressure piston launch system. Short answer, I think it's feasible with a 10-ft cylinder of 4-inch diameter PVC schedule 80 with 45 psi pressure, and a 8-inch diameter schedule 80 PVC accumulator 70 inches long. You would need a large valve you could operate very quickly. See the video on my channel for more detail.
I think the best and easiest launch if it would be a full circuit coaster is a tire launch
BUILD A LOOP AFTER THE TOP HAT.
money...............
The loop idea is fantastic!
Maybe we could find a way to launch into the loop, then do the top hat after that?
Ambitious? Yes.
Sure is fun to imagine, though, eh?
how is the launch system going to work?
What about a spring+pulley launch like in modern slingshot rides?
Try a kanonen type top hat after the launch
What about the barrel roll on the goal boss?
check out a vid from insider they did a vid on it but the barrel roll wasn't successful
wait you're doing WHAT
So what type of launch is it?
You should make one like superman escape from Krypton
So the Launch on this will Be Magnetic?
Why don't you incorporate a flywheel ? You can ramp it up slowly and then couple a steel cable pulley with a clutch to release all the energy in one time.
Do you make a rollback on your rollercoaster
Fartzan good point
Are you tearing down the old one then?
its in the other guys backyard he said in the vid :)
I am interested
Me too!
Please tell me that this will actually work..... It'll be so awesome if it does
We're gonna do our level best! I can promise you that :)
Lol wow
The truss could work, but I think you went about it the wrong way. Maybe start by building the regular flat track like before, then build the truss onto the bottom of that with an inch or two of clearance between it and the rails.
Tire launch wood probably be easiest
i think you should try to make magnetic brakes
I know you have a small space but you should at least add a couple bunny hills before the brakes
Inversions plz
Can you make me a coaster
I hope your joking
Why
@@wickothyplaysgames3572 because he isnt just going to make u one out of the blue for no money or anything is he? You act like your about 6...
@@Archman155 do you know what a joke is
You’re the tony stark of real life
A preliminary list of wild ideas for acceleration:
solid propellant rockets(s) on cart
water rocket(s) on cart
water jet shooting plate on back of cart
bungie cords on catch cart
dropped weight w cable/climbing rope and cc
catch cart attached to cable attached to spool drum motorized with hydraulic motor(s)
cc attached to cable attached to spool drum with large cantilevered weight (like trebuchet)
Tesla on jacks with tire off and bare wheel acting as spool for cable/rope attached to catch car
used Tesla motor and drum/cable/ccart
tie a rope from your Tesla to the cart.... what could go wrong?
hydraulic ram with pulley system to multiply distance
linear accelerator with electromagnets
large vacuum tube (hold plunger with cable to ccart, pull vacuum, release)
large pressure tube
propane cannon
I currently might favor the weight on a rope (24KN arborist/climbing dynamic rope, 5000 pound test) idea, seems simple to raise a weight with a counterweight. Anytime you are dealing with this much energy (up to 10,400 Joules by my preliminary estimate), it's going to be dangerous.
Migth want a proper station and brakes
Can I hire you to build me a backyard rollercoaster?
LIM is so much simpler. Or multiple tire drive launch.
I think you mean LSM
@@OT3S I stand corrected. You are right. I guess you could use LIM, but that controller would be massive, and expensive!
Insert airtime here
When are you going to make part 2
We are editing Part 2 today. it'll be up very very very very very soon!
Kitty Hunt instead of cheetah hunt
you are making a launch coaster but be careful if the seatbelt fails you Will not survive like the gold bloss because this coaster haves airtime that you building and gold bloss not

This can’t be safe
