Flying machines are mechanisms that employ slime cakes and/or love blocks, redstone blocks, observers, and pistons to move a structure of blocks in one or more directions, moving freely through air or h2o without support. They can also exist designed to carry along a player and/or other entities, which may be riding in a minecart or towed forth by honey blocks.
The mechanics of such machines vary slightly betwixt the Java and Bedrock Editions of Minecraft; This guide covers Java Edition and Bedrock Edition in split up sections.

The key blocks for flying machines, more than or less in order of advent:
Pistons are capable of pushing or (gluey pistons) pulling up to 12 blocks. These tin merely be bundled in a line in front of the piston, simply slime and honey blocks allow carrying forth blocks placed to all sides of that line.
Various immovable blocks (notably obsidian and tile entities such every bit furnaces[JE only]) provide limits and frameworks.
Redstone Blocks: The key bespeak here is while most other redstone ability sources are partial blocks that get broken by pistons, this i can be pushed or pulled past pistons, so a machine tin can conduct its own power source.
Observers are sensors for both the environs and adjacent parts of the same machine, which can likewise turn a change in i part of the machines into power elsewhere.
Slime and Honey blocks are similar -- both tin "stick to" other blocks at their sides, carrying those along with them when pushed or pulled by a piston. Their differences are as follows:
They do not stick to each other.
Slime blocks are solid blocks, which tin can take and transmit a redstone point, while dear blocks are transparent blocks which cannot.
Slime blocks bounce entities away from them, while love blocks drag entities forth with them (and preclude players or mobs atop them from jumping).
There are 2 master components of slime block flight machines:
The engine provides the basic control and motion, based on the idea that a slime block pushed past a piston will move next movable blocks, including other slime blocks, when pushed or pulled. However, each piston is limited to moving 12 blocks total.
Extensions uses additional pistons to allow tow along additional segments of a larger auto. Honey blocks tin can also be used to bypass the piston push limit past using adjacent slime block and honey block flight machines to divide the number of blocks in a structure among pistons. In Bedrock Edition, extensions are divided into leading and abaft types.
Note that the schematics in this section utilise the usual building scheme where layer i (or occasionally layer 0) is the bottom layer.
Engines
A simple flying engine. The fundamental piston is the but mucilaginous piston used in this configuration.
Engines are mechanical parts of slime-block based flight machines used to motion them.
In all cases, a major issue is control, especially how to commencement and stop the automobile. There are several options here:
A semi-automatic engine needs player'due south intervention to motion information technology, generally past updating a piston -- e.yard., using flint and steel on information technology, or rapidly placing tripwire against information technology.
A fully automatic engine can be started by a single update, say by breaking a block (maybe a push or a sign). A switch can be used, only is likely to exist left behind once the machine starts to move. Stopping them tin be more than difficult -- many engines volition stop only when they see an obstacle. If the obstacle is wrongly shaped, information technology may break the machine, thus a prepared docking station may be needed.
A few "drivable" machines take advantage of the indicate that a note block produces an update when played, so a player riding the machine can trigger annotation blocks to start and/or stop the automobile.
Engines tin also differ in bachelor directions and speed. The simplest tin simply move in a unmarried management, only ii-way and fifty-fifty diagonal motion are possible. Once again, defended docking stations are sometimes needed.
Schematic Gallery: Engines (Java Edition)
A ii-way engine can be fabricated with equally few as six blocks – ii Observers, 2 Slime Blocks, and 2 Mucilaginous Pistons. 2-way engines A and B (run across gallery above) show ii different ways to practise this. In both cases, the direction of flight depends on which observer is updated first. Note that in the diagram shown, each observer straight powers a slime block. The dock shown is placed so that the trapdoor will embrace the face up of the incoming car'due south near observer, which lets it send the machine back the manner it came.
Calculation honey blocks allows a role player to be carried with the machine in relative safety. The rideable engine shown adds two honey blocks, and a role player can stand on each of them. Information technology can be made with xiv blocks – 8 slimeblocks, 2 dearest blocks, 2 viscid pistons and 2 observers. Getting on and off is another problem....
Turbo engine A. Breaking the sign starts the engine. Turbo Engine A (encounter gallery) is a high-speed single-direction engine. It fits into 2×two×half dozen dimensions and uses fourteen blocks. Since zero ticking pistons is not possible on Bedrock Edition, this kind of flight auto will still be the aforementioned speed on Boulder Edition as normal flyers, yet, several 2.v meters per second flight machines have been created for specific use on Bedrock Edition.
An engine tin also move diagonally by moving alternately along two axes. The Diagonal Engine shown is best built out from level iii (the upper slime--and-piston layer). Information technology moves forth its slime-block diagonal, just is guided past immovable (e.g., obsidian) barriers on level 3, then it tin follow a straight or curved "rail", in whichever direction(s) it can move until information technology reaches a corner to block it. Information technology is started past activating either of the observers on superlative (placing a cake, flint-and-steel), and will move away from that corner (that is, it is also a ii-style flyer).

This video demonstrates two-way engine A above, with long slime-cake arms for harvesting, which shuttles between two prepared docks. Information technology can be triggered by placing a block atop the pistons, or by switches at the stations. Notation that the harvested crops will be launched at some speed, so this blueprint may be meliorate for an enclosed subcontract.
Extensions
Extensions are mechanical parts of a fully-automatic flying machine used to button an independent part of a large flying structure. A unmarried piston only tin push or pull up to 12 blocks. Extensions use additional pistons to "extend" a slime construction by assuasive more than blocks to be pushed.
1-style extension
A ane-mode extensinon has 2 parts: a normal piston in the rear, and a slime block (or more) with a power source in the front with space between them.
Once the rear role with the piston is pushed, the piston volition be activated by a power source from the front end office. It will button the slime block (and thus the adjacent role of the flying contraption and its extensions), which pulls the ability source with it. The piston volition then conciliate and prepare for some other button.
Some elementary engines are just made of looped extensions, such that, at any given time one piston is always powered (in these machines information technology is of import to identify the redstone blocks terminal).
A i-way extension. The piston volition be powered by quasi-connectivity.
Ii-way extensions
An example of how extensions can be used to create more circuitous structures such as this train. A two-way extesnsinor consists of an observer powering at least one sticky piston which pushes or pulls a function of the flying contraption. This is possible only in Java Edition because it's the merely version where pasty pistons (upon receiving a curt redstone pulse) tin push button a block and and so retract quickly without pulling information technology back. This type of extension will either continuously pull or push depending on whether the office information technology'due south supposed to move is initially retracted or not. If the role is initially retracted and the extension is continuously pulled, the gluey piston will continuously pull the function. On the other hand, if the part is ane block away ("not retracted") and the extensions is continuously pushed, the sticky piston will continuously button the part. This mechanism necessitates a switch within the flying automobile to independently retract and extend the extension before flying, because otherwise, the engine volition most likely be unable to push due to the "stuck" retracted extensions adding extra load to the engine's pistons.
Driveable flying machines
A flying auto tin can be designed to not only carry a player along, simply permit them to control the auto in flight, starting, stopping, or changing directions. Often due to lag, slime engines can bug assuasive the player to autumn through the automobile. This can be solved by placing the actor in a vehicle such as a minecart, past standing on superlative of a honey block, or by standing within a Composter. Note: Placing a minecart in any such build volition require a temporary rail, perhaps atop a temporary cake for convenience.
Starting the engine of a flight auto oft involves updating a piston or observer. Braking, on the other hand, isn't as straightforward to practise in survival considering a piston-immovable block must be present to stop the engine. A reliable braking method that was first popularized by SethBling is to attach a noteblock (or any similar redstone component movable by pistons) to the "face" of an observer that powers a piston. The piston is placed on the forepart of the engine, and since extended pistons cannot be pushed by other pistons, activating the noteblock at the correct time will stop the engine.
By using pasty pistons instead of pistons for the braking components, they also go 2-way extensions. These tin can be used to carry actress blocks, such as holders for minecarts/minecart chests, passenger roofs, TNT duplicators, etc.
Schematic Gallery: Driveable flying machines
Driveable flying machine A:
Dimensions: 8x4 collapsed
Materials: iv observers, x slime blocks, ii sticky pistons, 2 regular or mucilaginous pistons, 4 note blocks. For seating: 2 fences, 2 minecarts
Usage: To start left or right, click the note block with that pointer (backside you). To stop, spam-click the matching barred note block (alee of you).
Driveable flight car B is kurzawa6'south modified version of Drivable machine A, with minecart chests and a roof attached to the ii ii-manner spliters. One extension carries a roof to protect the commuter from phantoms, the other carries a cargo module with ii minecarts (optionally with chests)
Dimensions: 10x6, 2 high minimum, 5 high with roof.
Notes:
The slime block marked a can get another slime cake above it, with pinnacle slabs on each side sheltering the passenger/cargo minecarts.
The starred minecart is the "pilot's seat".
Before going either way, beginning make certain the roof is retracted by clicking the <̅ cake, and the cargo is retracted by clicking the >̅ block.
To get either mode , click the appropriate < >. To stop, spam-click the matching barred cake <̅ >̅ .

Driveable Machine C is a two-way machine which tin be reconfigured in the field to get the other ii ways, by mining and replacing four blocks. It can acquit ii passengers, and has two cargo bays for minecarts with chests (or manifestly minecarts, for passengers). It uses twenty slime blocks including the cargo trophy. Its utilise is complex, but may be worthwhile just for bragging rights.
Dimensions: 8x10, 3 high.
Diagram from video, showing ignition points and note blocks used for each direction. Annotation: This image is "sideways", with east and west shown equally equally upward and down. Usage: The auto is started past updating an observer (i of the 2 with open faces) twice, using a flint-and-steel or a h2o saucepan.
To go east:
Set fire (or water) behind the west-nigh observer.
Sit in the eastern minecart.
Before the burn down extinguishes, click the note block nearest you to release the brake.
Wait for the burn to burn down out (or remove the water) to trigger that observer once more and start the engine.
To terminate the engine, spam-click the same notation cake. Check that the carrier for your minecart is retracted, if non, click the note block again to retract it.
To go w, do the aforementioned in mirror paradigm.
To switch to northward-south motility:
mine the starred pistons (note the helpful logs beneath them) and rotate them a quarter-turn clockwise -- still facing outward, but the other outward
likewise, mine the starred observers, and put them in the positions and directions of the arrows.
To motion n and s, similarly twice trigger the "rear" observer, and use the nearer annotation cake to release the restriction and finish the engine.

Driveable Car D is a compact four-way engine that is controlled past applying a redstone torch to the key observer.
Outset with the central two slime blocks of layers ii and 3. The lower of these needs to be at least two blocks above "the ground" -- that is, the highest ground y'all intend to fly over.
Place the upper sticky pistons outward, and so use those to place the lower ones facing inward.
Add together the downward facing observer on the top of this, then the four-high slime pillars outside the pistons, extending above and below them. Use those to place the downwardly-facing observers on layer i.
Extend the slime pillars into T shapes, at the top on two opposing sides, on the bottom for the other 2. (this diagram has the summit T's at east and west). Identify the regular pistons at the ends of the T-bars, facing into the machine.
Place the layer-2 observers against the slime pillars, and then place the layer-4 observerd against the T-confined.
Note: the layer-4 observers alternately be placed atop their slime blocks (level five), each pair facing each (powering the next pistons). This placement fits the entire build in a 5x5x5 cube. All the same, that higher position slightly obstructs the rider's view, and then the original builder prefers the 4-level build.
Usage: The player stands on the pistons surrounding the superlative central observer, with a redstone torch in manus. The engine can be started in any direction by placing and quickly breaking the torch on that side of the fundamental observer. Information technology is stopped by once again placing the torch in the same identify (and leaving information technology until the engine stops). With the machine in motion, placing the torch may be hard, having a few spares may be wise. Note that it is entirely possible to fall through the corner holes, so step advisedly, and stay on the piston yous're riding while the machine is in movement.

More than circuitous engines
The following video shows a complex example, an infinitely expandable flying machine with a two-way engine and multiple extension (each conveying ii TNT Duplicators):
A iv-manner engine (ii vertical directions) that switches directions upon contact with a few blocks.
Flying machines are much more than restricted in Boulder Edition due to the lack of quasi-connectivity and other piston behaviors. In Coffee Edition, a sticky piston powered with a 1 tick pulse will driblet the block it is carrying. The absence of these behaviors makes it hard to create circuitous flying machines.
Simple engine 1
Simple engine i, observer and redstone cake provide the propulsion.
These are bones flying machine designs. The shown examples will move to the viewer'southward left.
Removing the block of redstone, or placing obsidian in forepart of the observer, volition crusade the machine to stop. This may be hard to do, unless in creative mode.
Simple engine 1 pattern, with added woodwork forming a gondola for the player. To start and end, add or remove a piece of wood (such as the piece of acacia forest shown here). For players who desire to ride their flying machine, it may exist hard to add together and remove the obsidian or redstone cake (especially in survival fashion). A slightly easier style is to add layers of another material (such as wood plank) to the auto, stopping just before the limit of what a piston tin can motion and doubling as a practical gondola for the player at the same time. From a position sitting on the machine somewhere, the role player may add together some other forest plank block to the machine, killing the speed. Removing the last block causes the auto to start again. Simple engine 2The elementary engine two provides a narrower but longer pattern, which requires less redstone than others (less redstone blocks). In this instance, the machine would brainstorm moving to the left once the observer on the right is activated. This can be done with a redstone pulse, or just lighting the face with flintstone and steel.
To reverse the direction of this machine, merely move one of the slime blocks to the back, and switch the piston and gluey piston.
This pattern is ideal when redstone is deficient, or when up to nine blocks demand to exist placed on the front end (the front half only consists of 3 blocks, with a total of 12 blocks able to be pushed by the piston).
Simple engine 2 with trailer
Trailer
By placing an observer and a sticky piston onto the side, 1 can build off of the Simple engine two design to brand the car bigger equally a whole. Keep in mind that multiple trailer attachments tin be placed on the side, up, and/or down simultaneously without exceeding the button/pull limit of 12 blocks. This is one way of creating a extension in Boulder Edition.
This addition can exist used to concur more cargo, whether it exist entities, chests (which are merely movable in Boulder Edition), or TNT (which can exist detonated by a following machine equipped with a redstone block).
Multi-directional engines
Bedrock multi-directional flying engine
Render station, side view
This design is multi-directional but it does require a return station to change the management. The observers are 1 block higher than everything else and take slime blocks below them. The render station is only an instance, anything that pushes the machine over so that the other viscid piston is unable to pull the terracotta should piece of work. It may assist to sentinel the videos below to come across some more examples.

Extensions
In Bedrock Edition, it is possible to create extensions, however they are only functional in one management. This first is the trailing extension (Trailer, shown above), and the leading extension. The leading extension can be made past attaching a backwards-facing observer directly backside a forwards-facing normal piston, both attached to slime blocks.
