VW aircraft engine conversion, Lone Star Light Sport Javalina twin cylinder, 50 HP, 4 stroke aircraft engine.
One of the most common experimental aircraft engine conversions in the world is the VW Type 1 based, long block , 1600 cc.
It currently powers Aerodrome Airplanes replica aircraft, Aerosport Quail, Benson Gyro, Brock Gyro, BK-1, BK-1.3, Corby Starlet, Cygnet, Double Eagle, Dragonfly, Easy Eagle Bi-Plane, Fisher Avenger, Fisher Youngster, Flagor Scooter, Hummel Bird, Hummel Ultra Cruiser, Jodel D-9, KR-1, KR-2, KR-2S, Legal Eagle, Mini Coupe, Nieuport 11, Onex, Pober Pixey, Q2, SkyRanger, Sonerai 1, Sonerai 2, Sonerai 2S, Sonex, Stewart Headwind, Taylor Monoplane, Teenie Two, Thatcher CX-4, Thatcher CX-5, V-Max, VP-1, VP-2, Waiex, Xenos and many more!
The Javelina is a twin cylinder aircraft engine conversion based on the 1/2 VW. Using American motorcycle heads and cylinders Lone Star light sport aircraft has been able to increase the airflow over the heads and cylinders by over 30%, and the cooling area by over 130%.
We currently have 2 prototype engines.
The first is a cut aluminum case using twin cam style cylinders. 101/82mm bore and stroke. 1320cc 80 cubes.
Weight on this engine is 122 lbs.
The second engine features a full magnesium case 89/82mm bore and stroke. 64 cubes 1050cc.
Total weight is 106 lbs less starter.
We will be monitoring the temps closely. CHT and EGT are expected to be lower than a 7.5 : 1 half VW thanks to 100% more cooling fin surface area on the cylinders!.
This setup will allow for compression in the 9.5 : 1 range in the future. Hoping to achieve 60 hp at 9.5:1.

Goin on my max.. excited to see performance!
That thing sure sounded like serious motor! I like the look of it as well.
Hahaha good . I am running mine with a model A Ford updraft carburetor. I also used the full block. Cut crank and cam in half. Moved the thrust bearing to the middle. I am very happy with the engine.
You got 1/2 the crank & cam and replaced the 2nd or 3rd bearing with the thrust bearing? Niether one of those is strong enough for the thrust bearing. What about the rest of the case? Chop it off or leave it?
I gotta see that.
Can you imagine if someone built new CNC cases for 2,4,6, or even 8 cylinder versions with those cylinders on it!!! Also many other motorcycle cylinders could be used like those big Honda's
I understand the weight penalty on the 4 cyl Honda Horizontal Motorcycle engine is prohibitive .
Pretty cool little package
I was happy to see that at the end of the video they included the engine running.
I have to say the sound was impressive, kinda like comparing the sound of a chainsaw to a tractor or Harley Davidson.
Harley "Evo" top end, on VW cases... Love it!
Robert Quick Really? Well then why not use an off the shelf H/D or S&S engine for light sport planes?
Weight!

Harley Sportster
@@dam4274 Besides weight the power pulses can cause problems not being evenly spaced.
@@dam4274 Back when the sport pilot rule was going into effect, there was a company, i believe it was named Hogair, that had a HD Softail big twin engine, w/ the counterbalance shafts setup, and was working on an airframe... It's now called www.skyray.us/
Went online. Have you decided on the price for the two versions of the 1/2 VW
The engine block in the demonstration appears to be original 1600vw version. Assuming that flange is for the propeller, where the crank pulley and belt for gen/alt. would be. Distributor/fuel flange location. Cylinders 2 and 4 utilized, with 1 and 3 plugged. One serious question would be: What have you done to the bearing nearest the flange? (#4) The crank snout was not designed to withstand that kind of torque. Air Conditioned bugs were known to need O/H twice as often due to torque applied to crank snout from a/c compressor.
The angle of those pushrods has me concerned about excess wear on the lifter bores. Has that been addressed?
WOW!!!!!...These dudes are 60 miles from me...Small world, indeed....!!!!!
BMW "airhead" motorcycle engine: 143lbs. 65HP... ("dual-plugged" recommended)
Where can I find one of these I want one bad for an old chopper frame I have
Very good idea! Vwavidson motor! I like one!
I wanted to try it years ago myself but never got past the beer drinking/thinking stage lol
Can this be used as a pusher? Thanks
Bangin on 2 cyls though. Doesnt that put alot of stress on the crank and bearings?
And why not go with 4 cyls? Heads & cyls can be modified with deeper cooling fins and scoops. At stock a duel port 1600 is 56 hp. I dunno what the weight is, but alot of it can be either reduced, replaced with lighter metals or eliminated all together.
I just recently pondered the VW air cooled for small aircraft idea. So I'm just curious.
Parts used indicate that this is one of the most advanced 1/2 VW aircraft engine conversions.
Is the Javelina offered for sale as yet? Or still under testing and development?
Just came across this on you tube seems like a decent idea but I can't find any information on it and the web sites won't come up did this flop?
When will you have a 75 hp version ready to go... need for Benson B-8M Gyrocopter?
Are those HD Evo sportster heads and jugs?
I'll believe it when I see it flying and meeting those claims.
cut some ports into it to make a 2 stroke out of it, some vw air cooled were modified in to 2 stroke with boost, would make a nice uniflow dfi with dry sump, a vro oil injection pump and amsoil dominator 2 stroke oil. thats what i would run if i had one.
A prudent approach to any claims about technological offerings, doubly so in aviation.
Yes, and the proper question, would be after expecting tbo of at least 1,600 hours, would be to name one, or at least the one that has accumulated the most hours. The fact that this is a new engine, it’s probably best not to be suggesting those kind of hours. Seems like a nice enough guy to me though, hope things go well for him.
Would be great to put it in a Baja Bug with custom made cooling tin and fan.
did this engine ever go into production?
This gentleman is pushing out some fantastic performance words. Sure would be nice if it actually works out to be true. I rebuilt some 1500 cc VW's that never quite hit 55 hp.Higher compression ratio's produce more power, but also a lot more heat. An air cooled engine has a hard time getting rid of that heat. The principal reason why VW finally went to liquid cooling in their cars. And motorcycle engines are mostly liquid cooled now as well. Also, noting that the work end of the motor is now reversed to where the accessories were once driven, wonder if the snout of that crankshaft can take the prop load. It does look sweet though.
The 1/2 VW engines put out about 45 HP using just the standard cylinders and heads. These units use, as described are using modern cylinders and heads from the motorcycle industry.
If you just look at the cylinders and compare them to a standard VW cylinder you can see why they can easily get rid of the heat.
The Ultralight Flyer
An engine's ability to make horsepower is largely determined by the Flow of the Cylinder Head and the design of the camshaft. HP gains from compression increase are nominal.
How much money is the magneto 1/2vw?
Dang that thing is loud!!!!!!
Dual plugs per cylinder?
Where has this engine gone??????
Have flown behind a couple of VW engines but the last one I had on a Cygnet SF 2A had an oil leak that could not be found. The engine ran great but it spewed oil out at only about 4 to 5 ounces per hour but it was enough to cover the belly of the airplane every time I flew it. Not a huge issue but enough to make me concerned. The only way to fix it would have been to take the engine out to find the leak. I've talked to others that had the same issue and just accepted it.
Is it under or near the oil cooler in/out on the case? Thats where I found mine. I thought it was the oil cooler replaced it and seals a few times. Then I happened to see this itty bitty crack on the case that went from the inlet down about 1/4 in. Across and back up, but stopped before cracking off.
It was driving me nuts trying to find it.
@@AngryHybridApe Was yours a half VW?
@@AngryHybridApe My 4cyl VW was burning oil on a warped cylinder that coated the bottom of the KR2 . It was barely visible as smoke but consumed enough oil to cause the oil pressure to fluctuate after 1/2 hour of flying.
I need such an engine. Please tell me how much it costs
Why was the price not mentioned??
What do they cost??
Kind of like burger king, Good one
Very impressed... Does anyone know if the crank full length or some kind of half shaft?
It looks full length on their website. All full case 1/2 VW's that I've seen so far have modded full length cranks in them.
The crank is cut just behind the mid bearing area. Take a tad of machine work to get the spacers and the H bearing right for crank end thrust cam cut also.
There is space shims that allow for thrust adjustment. And the crank journal has to be drilled and taped for a bolt to hold a thrust plate on back of cut crank.
Also the cam needs retarding on cam shaft because of RPM of prop. Cannot turn prop tip faster than speed of sound. It will throw the wood prop if RPM is too HIGH. Needs horse power developed at a lower RPM than a auto engine.
@@jlyle51
Ok, got it. But wouldnt have been easier to just counter balance the unused rod connections and leave the case whole?
Damn. It just doesnt sound like it would run for long. Those little engines put up with enough as is.
Btw. Do you run 1&3, or 2&4?
Harley sportster cilinderhead?
I thought it looked just like a Harley cylinder, & heads too.
Harley-Wagen or Volks-Davidson?
Pound for pound can this replace a half VW like in a hummel bird ?
I'd love to see this engine in a Motorcycle
Without running it ONCE: "We expect an over 1300+ hour TBO...." This is the number 1 way to kill a design. Once this has a few thousand hours on it, THEN set a TBO. HKS started with a 300 hour TBO and PROVED it could do a 1000 TBO over the span of a few years. Understand me, I DO want this to succeed, it seems like a decent design(on paper...), but please prove it a bit before you say this is the next best thing out there, thanks!
David miorgan So...you've been running a half VW engine with BRAND NEW Harley Davidson EVO heads while adapting it's hydraulic lifter setup for 40 years now, eh? Wow, do allow me to borrow that time machine of yours someday ok? 🤣Do at least LOOK at the video before commenting, OK....sheesh....
Michael Livote is there a conversion for hours to miles since this is automobile engine base. It would be easier I think to see what the TBO would be??
@David miorgan This is NOT a VW engine. It's cobbled together out of different bits in a configuration never tried before. I agree that their TBO is pure imagination until it's been proven.
@@tphone720 Most of this is a proven VW engine...but then there's the motorcycle parts that are not nearly as proven. Usually it just takes time for the manufacturer of these engines to see if they will pan out and work properly---this isn't always the case of course. As for converting miles to hours, I don't think I've ever seen a chart anywhere that standardizes this, that's why I tend to go by hours only as this is now an aircraft engine and that's how they are measured. Time will tell on the hours this one can go.
He didnt say the TBO was 1300, thats just what they are expecting it to be.
More or a little less vibration than the hardware stores paint shaker? Ive seen several of these and better glue the rivets in also ....how much weight?
Video I watched of it running - does not show an excess of vibration.
The Ultralight Flyer
@@ultralightnews
Ive seen a few vids of them ...its like a paint shaker is under the bonnet was considering one. Told forget it by experts
@@davebar2017 internet "experts", right?
55 hp? I sure would like to see the dyno numbers...
how is it that 1/2 the engine is making twice the HP?
Higher compression ratio, better flowing heads, and far greater cooling surface.
Thats what I was wondering. 2 cyls are gonna make that thing shake too. I dunno. I just gotta see this shit to get a better understanding.
So what makes that motor dissipate the heat to make over 42 or 43 HP? Must be climb out power for short bursts.
The large cylinder cooling fins get rid of the heat vs the standard cooling fins on the VW engine.
The Ultralight Flyer
@@ultralightnews plus there's a lot more air moving by the engine in an aircraft rather than a motorcycle.
There is also a very large propeller acting as a giant fan.
IF THESE JUGS ON A MOTORCYCLE CAN MAKE MORE POWER, WHY WOULDN'T IT MAKE THAT RELATIVELY LOW POWER OUTPUT WHEN AMPLE COOLING IS AVAILABLE?
Very nice
Quanto custa qual o.peso e quantos CV para esse motor?
Let me know when you will actually be able to buy one.

S&S Harley top end?
Sounds like they are using Harley cylinders, I would prefer to see aftermarket cylinders like the S&S, they would probably be more reliable.
how meny price sir
I want to put it back in Bug with the weight loss !
So, I'm watching this and thinking.
Is that a mini-MAX back there?
steve
Yes it is a TEAM Mini-Max, probably one of the VW engine models.
The Ultralight Flyer
That thing would kick but on a legal eagle
well there is a 2 stroke potential with a high power laser burning ports into the aircooled liners. nothing new here
Harley heads on vw block
HKS700E !
can those even be bought brand new anymore? Are they still in production?? Enquiring minds want to know....
@@MrZrryan2 www.greenskyadventures.com/
Рад вас здесь приветствовать. Вы на своём пользуетесь mixture kontrol ?
I'd put it back in a Beach Buggy less weight .
Bit more HP .... win win ..!
Really, 55 hp on Harley jugs and head, less than 3000 rpm. Not gonna happen.
looks like they repurposed Harley Sportster cylinders and heads to fit on that engine.

I’m going to throw my two cents in about the VW engine conversion I’m 57 years of age and over the years I’ve owned several Aircooled VW vehicles and about 12 SeaDoo brand watercraft as far as a Airplane engine I personally would want reliability in comparing VW to bombardier , hands down to the VW I’ve had several SEaDoo motors seize on me and my brother in law parts from local distributors could be difficult to obtain and even sometimes incorrect we had a brand new Watercraft that blew several pistons in the same block although it was covered under factory warranty after a investigation from the main company they found their factory authorized repair facility was using the incorrect piston each time they rebuilt the engine and even that the entire Watercraft had under 50 total hours on it the Dealership tried to tell us it wasn’t going to continue fixing the machine under the warranty any longer because the machine was over a year old ? Keep in mind the machine was over a year old but because of the time of which I had the machine being winter and cold the new machine sat covered inmy garage witerized by the dealership for months and months that ironically was one of the first machines with a high tech computer and the dealership and factory did have all the information on how the machine was operated when it did run in SeaDoos defense we spoke to their President in Canada about the problem and he personally authorized a brand new engine to be shipped fromCanada and installed at another Dealership at no cost to me so the Company did do the right thing mainly because I didn’t want a new machine with a rebuilt motor because I paid and ordered a brand new Watercraft and engine , now on a 1972 VW Beetle that I owned , although the original motor was refreshed in the 1980s with new pistons,rings ,and gaskets despite having over 1000K miles on the engine it is still running in another Beetle today on the original block and Crankshaft , in a car if the motor dies you can coast to the side of a road in a Airplane that’s a little more complicated so I would go with the old reliable VW
...damn...That wuz THOROUGH!!!
I don't think he's going to get anywhere near the TBO he is estimating.
And the reason for thinking that is? You already have VW conversions that are getting that kind of TBO. Using more modern proven technology would seem to give an even better result.
The Ultralight Flyer
The average Harley engine will require several top end overhauls before the average air cooled VW engine will need its first one. If air cooled VW engines needed rings and valve work every 25k they wouldn't have the reputation the VW Bug had.
Why not?I've got VW pd ,engine 265,000 miles equating to near 8000hrs and never touched so 1500 to 1800 hours would be a doddle.
50hp is not very powerful. That may be the reason Rotax stopped making/selling the 503 back in 2011.🙂
I've been hoping to find someone who makes a type IV VW engine (used on '72 and newer VW Bus, 914 Porshes + 912 Porshe) that was made for aircraft. This engine has a much beefier bottom end than the Type I used on VW Bugs. I was in Advertising for 30 yrs and one of my clients made Only Racing Type IV engines that put out 200+HP! The builder installed an additional head bolt on each head to prevent oil leaks due to this whopping HP increase. I had one of these Type IV engines with dual webbers in my VW Bus. I would drive up to Reno, NV from SF going 80mph with ease. It was oil cooled with a 2.5qt deep sump and external radiator (mounted 3ft away from my engine with an electric temp. controled fan. Total 7qt system! I think a water cooled head system would be better and lighter.
Harley Davidson Cylinders .......humm .
