“No hoverbike worth anything without a cute blondie posing on that” /Pauler’s 4th law/

1 Preface for our “Star Wars Real-Engineered” mini-series

It is very clear that no one can make Sci-Fi movie without departing from existing scientific knowledge. However, it can be done in the clever way, like Stanley Kubrick’s “2001 a space odyssey”. Alternatively, it can be done unnecessarily raping very basic laws of Physics valid through the Universe - like in Babylon 5 or in Star Wars - serving the marketing needs of target audience. Our mission is trying to re-create the fanciest Star Wars-gizmos from Lego Technic using strict engineering point of view, based on current or slightly extended technology.

2 The Star Wars gizmo real-engineered: Rey’s Speeder

Rey’s Speeder appeared first in 2014 trailers of Star Wars 7. Disney wanted to minimize risks, and re-vitalized here an old piece of concept art proposed originally for Star Wars 6 in 1983. George Lucas discarded it that time in favor of the famous Aratech 74-Z Speederbike designed by Ralph McQuarrie for its better look.


Figure 1: Rey’s Speeder

From engineering point of view, Rey’s Speeder is just as obsolete and awkward design as Aratech 74-Z:
- If you have pot-sized repulsorlift engines driven by laptop-sized energy cells capable of lifting several hundred pounds at several thousand feet, then why to tinker with primitive turbojets and clumsy jet fuel for level speed? So, it is illogical even at its own universe.
- The really bad news are that by general relativity theory, gravitation is not a force - which could be repelled somehow - but special geometry of spacetime around large masses. Even antimatter has positive gravity. So repulsorlifts are not only uninvented yet, but pretty much impossible by current fundaments of Physics.
From the several tons of MOCs modeling Rey’s Speeder, we just mention: Robert Lundmark’s MOC, which exceeds the official TLG set 75099 by magnitudes in almost photo-realistic brick usage:


Figure 2: Robert Lundmark’s Rey’s Speeder MOC

Star Wars concept art has destructive effect on engineering thinking of several generations. Lego 42063B-BMW Concept Hoverbike shows in crystal-clear way, how modern concept artists think about hoverbikes: it is a bike minus wheels and some winglets and nozzles added. How lifting force is generated? How stabilization/balance is maintained? Where is the landing gear? Where is any redundancy/rescue system? These are the inconvenient questions when the good old antigravity principle comes into the picture:


Figure 3: Lego-BMW Hoverbike

3 Prototype hoverbikes in real engineering

The funny thing is that while movie blockbusters still use 40 years old sci-fi concepts, with the advent of modern multicopter drone- and LiPo battery technology, hoverbikes moved from pages of pulp fiction into more or less working backyard prototypes and scale models:

- Malloy hoverbike is a compromised solution between control and compactness with 4 closely spaced, half-overlapping protected propellers. It performs well as commercial quadcopter with underslung droppable cargo. With a person riding on it, it performed only low level untethered flights, hovering in ground effect. One can see why: reduced roll stability + riding human (as unstable moving cargo with high center of mass) is not a healthy combination.


Figure 4: Malloy Hoverbike

- In current drone technology, FPV tilting rotor quadcopters have the best control combined with relatively high level speed. One of the finest is eXdrones Swift TR280 Tilt-Rotor FPV Racing Quadcopter with streamlined airframe:

eXdrones Swift TR280 Tilt-Rotor FPV Racing Quadcopter
Figure 5: eXdrones Swift TR280 Tilt-Rotor FPV Racing Quadcopter

In our current model, we aimed to extend tilting rotor quadcopter concept to full size, high speed attack hoverbike, with foldable propeller winglets to achieve additional lift at high speed and compact storability. As current LiPo battery technology is still far from providing sufficient energy source for it, we propose a hybrid drive: Besides small batteries useable in silent mode/emergency landing for 60-180 seconds, it uses latest advancements of range extender technology for drones. They are rotary engines or micro turbojet engines connected with an alternator (often called turbo generator). One fine example is Capstone C65 Microturbine generator: single rotating part on air foil bearing, no lubricant, no coolant results in high reliability and low maintenance requirement. Usage of new 3D printing technology (metal alloy powder + laser) can reduce weight and manufacturing costs of such sophisticated high-efficiency turbines considerably:

4 Our foldable tilting rotor quadcopter Hoverbike

Our Hoverbike MOC is a piece of concept art, but it is strictly tied to real engineering principles described above. It consists of 1216 bricks, resulting 4 power functions, 28 manual functions and 30 non-working features in scale 1:10:

Functions overview of Hoverbike
Figure 7: Functions overview of Hoverbike
See model in LDD

As real tilting rotor quadcopters are built from high tech carbon fiber reinforced composite materials instead of ABS bricks, this MOC very clearly exceeds the physical limits of Lego bricks (even we tried our best to reinforce it). Therefore, its playability is almost nil, and it serves as demonstration of a concept.

Hoverbike overview animated
Figure 8: Hoverbike overview animated
See model in LDD

One can see that Hoverbike not only have tiltable propeller arms, but they are profiled to form 4 winglets generating aerodynamic lift at high level speed. Foldable winglets are reinforced by one-piece slideable main wing spars made from ‘Technic axle 16 studs’ inside their internal cavity (see the spars in the following animated cutaway figure):

Cutaway view of Hoverbike animated
Figure 9: Cutaway view of Hoverbike animated
See model in LDD

Pitch of the 4 winglets can be set from -75° to +75° independently from each other using 4 mechanical, 2-stage worm+Z8 gear controls placed at the pilots leg, close to electronic yaw control pedals. This way at high level speed, they serve as combined ailerons/elevators. This is important because conventional tilting rotor FPV racing drones cannot tilt rotors more than 40° forward - otherwise there will have very strong Dutch roll tendency – and it limits their level speed. Here, Dutch roll can be compensated by winglets used as ailerons. Moreover, 4 winglets allow the craft to stay aloft at level speed with only 1-1 electric motors working side by side, providing some redundancy.

Figure 10: Hoverbike in hovering mode above desert location
See model in LDD

As Hoverbike is optimized for high level speed instead of extended hovering, the twin turbo generators placed at the tail produce not only electric current for batteries/electric propeller drive, but they provide some limited forward thrust by jet exhaust. Therefore, at hovering above single spot, propeller winglets are tilted somewhat backward to counterbalance thrust force of turbo generators. This solution results higher fuel consumption in hovering but enables attaining higher level speed.

Landing skids are manually retractable by a worm+Z8 gear mechanics placed at pilot’s leg, to reduce drag at high level speed:

Hoverbike is more compactly foldable – roughly in the volume of a smaller bobsleigh – than any other ultralight aircraft/rotorcraft capable to carry serious armament.

Hoverbike folded
Figure 13: Hoverbike folded

Folding/ opening propeller winglets and propeller blades is a simple manual activity can be performed by single person in 3 minutes. We show the sequence for the rear pair of winglets in the next animation:
1.Open rear right winglet 90° backward
2.Open its propeller blades setting their pitch to +20° with the small green arms at the propeller hub
3.Pull out wing spar from rear left winglet backward
4.Press wing spar through airframe into opened rear right winglet
5.Open rear left winglet 90° backward
6.Center wing spar among rear left/right winglets fixing them
7.Open propeller blades of rear left winglet and set their pitch

Folded Hoverbike can be transported even in the cargo space of a small hybrid tilting rotor multicopter / tracked personnel carrier called Flying Personnel Carrier (FPC).

Loading folded Hoverbike into Flying Personnel Carrier (FPC)
Figure 15: Loading folded Hoverbike into Flying Personnel Carrier (FPC)

Hoverbike is loaded through rear motorized cargo ramp of FPC, pulling it with motorized cargo winch into cargo deck. Hoverbike consumes space of all 3 crew of FPC, so FPC works as autonomous drone when carrying it.

Armament of Hoverbike consists of 2 spring driven, shooting, portable LM-7B light machineguns auto-loaded from drum magazine of 16 1.5×5mm projectiles. Both machineguns are equipped with 5 spring driven shooting Cradle Grenade Launchers (CGL) with 8×53mm projectiles. Between the machineguns, there is an RPG-6 spring driven shooting RPG launcher for 1 16×96mm projectile. Also, there are 2 light bombs detached manually. We can see all weapons firing in the next animation:

Hoverbike weapons animation
Figure 17: Hoverbike weapons animation
See model in LDD

Portable light machineguns are equipped with pistol grip, optical sights and gun lamps besides 5 CGL grenades, so they can be detached from Hoverbike and used as normal infantry weapons in case of emergency:

Hoverbike portable light machineguns

Every military aircraft worth as much as it save the pilot in emergency, as new aircraft can be manufactured in matter of weeks, but it takes 20-21 years to manufacture a new pilot. As Hoverbike cannot make dead engine crash landing at all, we designed there an extremely compact spring driven shooting ejector seat. It can be triggered by pulling 2 arms placed at pilot’s shoulders, and ejects pilot 45° backward up, safe distance from propellers and turbo generators:

Ejector seat of Hoverbike deployed
Figure 19: Ejector seat of Hoverbike deployed

Rescue parachute is stored in an openable box at the pilot’s belly, integrated in the harness of ejector seat. We modeled mockup of the opened rescue parachute made from ‘Palisade brick, transparent’ and ‘String 30 cm’ parts in an auxiliary model.

Parachute of ejector seat is opened
Figure 20: Parachute of ejector seat is opened

Behind the ejector seat, there is a fire extinguisher and droppable life raft inflatable from pressurized nitrogen bottle, in case of emergency above water:

Life raft of Hoverbike deployed

Hoverbike is equipped by rotatable camera turret forward part of underbelly, a very usual component of multicopter drones. Rear part of underbelly has a large mine detector coil. Hovering extremely low and slowly in ground effect, Hoverbike can detect landmines with reduced chance of triggering them, as it does not touch ground at all. In the next figure, we can see Hoverbike in a night mine sweeping mission, accompanied by Flying Personnel Carrier. The latter carries a small Tracked Foldable Shovel Machine locked on board, which picks up the landmines detected by Hoverbike from low level hovering. As FPC works without crew in autonomous mode, no human is endangered by mine picking:

In the middle of underbelly mine detector coil, here is a large LED searchlight panel can be used in Search & Rescue or law enforcement duties. Underbelly camera turret can shoot evidence video footage:

Hoverbike has retractable cargo hook in the middle of underbelly, where smaller underslung cargo (a light machinegun, or a chainsaw) can be airlifted:

5.1 Drivetrain

Drivetrain of Hoverbike
Figure 26: Drivetrain of Hoverbike
See model in LDD

The TLG drivetrain of the MOC consists of 4 LPF2 M-motors controlled by 2 LPF2 SmartHubs. In the real drivetrain there are additional elements of hybrid drive as non-working features: SmartHubs emulate not only (D3) small batteries, but in the larger portion of their volume, they model (D1) jet fuel tanks filled through (D2) fuel refill caps. Fuel is consumed by (D11-D17) twin turbo generators, which drive electric motors and charge small batteries. Battery-only mode is used for 120-180 sec at silent sneaking/ emergency landing flights. Manual quadcopter controls are non-working features: (D8) pitch/roll control column, (D7) yaw control pedals, (D9) main throttle.

We modeled turbo generators in conventional turbojet layout with (D13) oversized alternator on its main shaft between (D11) 10-blade axial compressor, and (D14) 3-stage centrifugal gas turbine. Besides electric current, some thrust is generated by (D16) jet exhaust nozzles:

5.2 Propeller tilting

Independent 4 propeller winglets tilting mechanism of Hoverbike
Figure 29: Independent 4 propeller winglets tilting mechanism of Hoverbike
See model in LDD

Independent tilting of 4 propeller winglets between -75°..+75° is performed by manual controls placed at pilot’s leg. 4 independent 2-stage worm+Z8 gear mechanics creates transmission with 1:224 gearing ratio between 4 Z28 turntables of propeller winglets and 4 propeller tilt roller pedals made from ‘Worm gears’.

5.3 Propeller folding

Propeller winglet folding and slideable wing spars of Hoverbike
Figure 30: Propeller winglet folding and slideable wing spars of Hoverbike
See model in closed position in LDD
See model in opened position in LDD

Propeller winglet/ propeller blade folding/opening is done manually by the process described earlier. In folded position, 2 (F3) winglet main spars are stored in forward right- and rear left winglets. When winglets are opened, spars are centered among left/right winglets, locking them in orthogonal position to airframe. Airframe has (F2) forward/rear mid-line supports of wing spars. 8 propeller blades are locked in open/closed position and in 0°..+20° pitch by 8 (D5) propeller blade locking arms.

5.4 Retractable landing skid

(L2) pivot axles of (L3) landing gear legs are rotated manually via worm+Z8 gear combo by (L1) driveshaft at gearing ratio 1:8.

5.5 Ejector seat

Ejector seat of Hoverbike
Figure 32: Ejector seat of Hoverbike
See model in locked position in LDD
See model in firing position in LDD

The main challenge was in creating such a compact ejector seat, that no space left at floor panel at all because of propeller tilting and landing gear mechanics. Therefore we had to design a harness, which wraps around torso of pilot, using (E8) ‘String with connectors’ and (E3) ‘Chain 6 studs’ parts. (E4) openable parachute box is integrated in belly part of harness. The back panel contains 6 (E9) propellant springs disassembled from ‘Shock absorber’. (E10) double launch rails are made from ’Standard 53mm’. (E6) launch triggers are placed at pilot’s shoulders. (E2) parachute connectors serve also as Pitot-tubes to measure air speed of ejected seat at parachute opening control. The seat has (E1) foldable armored headrest.

5.6 Navigation systems

Navigation systems of Hoverbike
Figure 33: Navigation systems of Hoverbike
See model in LDD

The very limited space on board allowed only very basic avionics of ultralight crafts, besides (W27) computing gun sight with HUD. Underbelly, there are (N8) rotatable camera turret, (N11) landmine detector coil and (N12) LED searchlight panel. There is a rearview camera in the foldable vertical stabilizer, and pilot has helmet camera and helmet display.

5.7 Armament of Hoverbike

Armament overview of Hoverbike
Figure 34: Armament overview of Hoverbike
See model in LDD
One of our main development goals was to squeeze surprisingly nasty armament pack compared to such a light and small craft. Besides the spring-driven shooting weapons detailed below, there are 2 (W26) light bombs and 12 (W31) jetissonable IR decoys to divert IR-homing missiles as non-working features.

5.7.1 LM-7B spring driven shooting, auto-loaded, portable light machinegun with Cradle Grenade Launcher (CGL)

Firing cycle of LM-7B animated
Figure 35: Firing cycle of LM-7B animated
See model in LDD

LM-7B is a compact spring-driven, shooting, auto-loaded, portable light machinegun. We show here working of the single grenade version for better visibility of parts: (W15) Propellant springs are from disassembling TLG part ‘Shock absorber extra hard’. Projectiles are non-TLG parts as Lego does not produce reasonably small parts due children safety reasons, moreover ABS material is not enough heavy to be efficient projectile. Therefore 1.5×5mm projectiles are made from copper electric wiring can be found in any hardware store. Mass of the projectile is so small that it can fly stabile flight path even without spin stabilization because of the density and drag of air. Drum magazines are not very popular in modern automatic weapons (although they were used extensively between WWI and WWII), but building from Lego Technic, they provide much more compact and easily moveable ammo feed than box magazines or belt feed. Z-16 gear from TLG ‘Gear shift’ rounded by ‘Tire 24×7mm’ can hold 16 rounds. (LDD cannot draw the tire pulled on Z-16 gear, so we mock it with the red rubber ring as placeholder.). The weapon is equipped with optical sight, gun lamp and Cradle Grenade Launcher (CGL) shooting 5 8×53mm flying spigot type grenades with the help of 2 propellant springs each (we show here single CGL grenade).

5.7.2 RPG-6 spring driven shooting RPG launcher

RPG-6 animated
Figure 37: RPG-6 animated
See model in LDD

The main difficulty creating any decent looking RPG launchers from Lego is the complete lack of thin long barrels with 1 stud inner diameter (probably due to children safety reasons). Any of such a barrel solution from TLG parts will result in nearly 3 studs outer diameter, which would look terrible. Therefore we invented pseudo-tube launcher. 2 stud / 1 stud diameter RPG is launched from among 4 parallel ‘Technic cross axles 12M’ spaced 1 stud vertical/horizontal gaping. This will result in reasonably sized launcher. Technically, real RPG launchers could be built this way also, but hot propellant gases would roast personnel to death. To create simple and compact launcher, our RPG has flying spigot type bolt: it flies out together with the projectile, leaving propellant springs behind.

5.7.3 Chainsaw used at airlift scene

Chainsaw animated
Figure 39: Chainsaw animated
See model in LDD

TLG produces chainsaw parts both in Bionicle and Minifig scales, but they are rather primitive, one-piece-molded stuff. The modeling challenge was there to create more realistic device using ‘Motorcycle chain’ and ‘Lego plastic motor’ parts. The most troublesome issue was the chain blade, but then I found Technic part ‘Wing 7M’, which is totally unsuitable for wing section rib, but almost perfect for chain blade.

7 Unsolved issues of Hoverbike

Our modeling of Hoverbike was enough realistic to pop up some basic problems, which can explain, why Hoverbikes won’t swarm above your favorite Wal-Mart megastore on Saturday mornings – at least very soon:
- Cost of high energy density range extenders: rotary (Wankel) petrol engines are relatively cheap and compact to drive alternators, but they have high fuel consumption from expensive high-octane petrol, require lot of maintenance, and not enough reliable because of their suddenly dying edge seals. Micro turbines are much more reliable and fuel efficient, can be fed almost any fuel, but more than ten times more expensive, because they require high grade heat resistant metal alloys, and they have highly complicated internal layout to be efficient. Although, modern 3D printing manufacturing methods can cause a cost revolution in micro turbines in the near future.
- Lack of dead engine crash landing: multicopters are mechanically much more simple and cheap than helicopters, but they are not capable of autorotation dead engine crash landing of helicopters. It is questionable whether FAA will ever certify any civilian aircraft carrying humans without dead engine crash landing capacity. Moreover, shopping grandmas don’t really like to be ejected by ejector seat, while usage of ballistic parachute saving the whole craft is troublesome at Hoverbike: too small space on board and too many rotating propellers to entangle/cut parachute lines.
- Redundancy issues: lack of dead engine crash landing risks can be mitigated using more than 4 electric engines and propeller (e.g. 2×4 contra rotating propellers on 4 winglets). Building from TLG parts, there is a problem that LPF2 M-motors are not enough compact for it. In real engineering, it means reduced ground clearance of propellers, which makes landing in crosswind more difficult.

Quoting Jeremy McCreary The loss of democracy in Hungary in a single administration is a tragedy. It should also be a warning to Americans, because Trump would love nothing more than to replace democracy with kleptocracy in the US as well. Unfortunately, we rarely hear about your plight here.
Democracy is not lost via administrations, but in people's soul. In the US there are still working institutions and some common sense in middle class to stop or at least slow down Trump's rampage. The real problem is when there is no middle class or it gets poorer, and masses of low-educated people in the landside have no any trust on institutions, and start to expect the 'advent of good and just emperor, who makes order in chaos'. Just like in Germany in 1933... Or in Star Wars 3...

The power of fake information is emerging not only in education. I live in Hungary, where a not so old democracy is just transforming back into a Putin-styled dictatorship. Yes, there is Russian economic pressure in it, but there was no any Russian military invasion (like in Ukraine). Lazyness, convenience and dark stupidness of my fellow Hungarian citizens led to electing a dictator on democratic elections, who did not really made secret from that he want to stop democracy (just like Hitler). Nobody did care about it, nationalist bla-blah was very attractive.

Quoting Henrik Jensen As usual an absolutely amazing post! Even though some parts are reused from earlier posts it Must have taken hours and hours to produce something like this. I really like the foldable Hover-bike design, very creative and imaginative!
Thanks. Yes, it is a perfection of an earlier model. In the meantime I am working on something really new and big one... maybe for next Christmas...
