Doesn't that look good!

Oops,stupid computers! When you get there,click on to ENYA and search
out the new SS 15 Diesel.

Here's the link you want. I find it interesting that although they call this a deisel and it looks like a deisel, when you hover over the picture, it says "glow powered". (Edit inserted by Leonard Neumann. By the way, I moved this from the Product Reviews section since that forum is reserved for actual reviews of products or sources that people have used.)

Great to see a new Enya 15 diesel. Just don't try and get one from Altech. They will not import them and will not special order them. Your just as well of ordering them from Australia. Thats how I got my Enya 11 Diesel

Notice the price difference between the 11 and 15. The 11 is $115 US and the 15 is $50 US. Wonder which one is the strongest?

There's a "gotta have!"

SCHWEET looking motor. Knowing that it is also Enya quality is a real plus. I flew control line stunt diesels with Larry Renger/aka Designman a while back and while they can be somewhat cantankerous,
they were alot of fun. A lot of power in a small package.

Spend half the money and buy a MVVS .15 diesel, you won't be disappointed ..... jusy my opinion. You can buy it right here in the States at www.mvvs.com .... this is Morris Hobbies. The newest MVVS .15 diesel engines have a neat blue anodized head too .... you can turn the exhaust left, right, or rear to suit your model installation needs .... these engines are true dual ball bearing schneurle ported power houses, plus they are very fuel efficient.

It says $126.95 USD, I don't see that being any kind of bargain for a plain bearing .15 diesel. Yeah, it says it's a BB, but the picture is not a BB engine. Sometimes webmasters post the wrong photo, but not me, no, I wouldn't do that! Steve

It is the wrong picture! I emailed them about it a while ago, and the motor they have on sale (or have on order) is a TBR. One of the reasons why it's nearly USD130 is the "slipage of the USD in comparison to the Australian dollar (and almost everyone else). Today it's about
0.73AUD = 1.00USD! Eighteen months ago AUD 0.54 = USD 1.0
You blokes had it real good!!

It's still a hundred and thirty bucks for a stinkin SPORT 15 engine!

If this was a high performance TR diesel I'd be excited, but for a sport 15?

Whoooo whoooo I can't wait to stand in line for that. Maybe I can slurp down a couple of 15 dollar Cokes while I stand in line with the thousands of other guys.

William mate!,

where would you get a high performance twin ball team race diesel for 130USD? A PAW TBR diesel "sports engine" would cost you about the same. It is an Enya, it would probably last a lifetime. It will be snapped up here by collectors and probably won't even be released in the US. If it wasn't for this thread you wouldn't even know about it. As for your $30 cokes, our local hobby shop has a Topflite FliteStreak ARF onsale for AUD250. About USD185! An LA .46 Costs about USD103, and thats the RC version. Count your blessings.

Hi Ray,
William Crane and Injunut are correct...In the USA we can get MVVS and
Paw engines much cheaper than You can In OZ,I guess. An MVVS .15BB costs about $55.00 from Ed Carlson and a .15TBR costs $84.00....the .19TBR is $87.00 and the 249 GTS-2 Race Tuned C/L F/F Double Ball Bearing is a Whopping $126.00....any of these engines will be better choices(except the GTS-2)for sport and stunt flying than the Enya. I would be willing to pay $75.00 for the Enya if it were equal in performance to a PAW .15 plain bearing. So maybe you should check into the costs for a getting a .15TBR "sports engine" fromm the USA.....? I Really hope You can do it.
Tony G

I keep forgetting you are in the land of Oz and are not privy to good prices and therefore are stuck with Enya's, shame really.

All kidding aside, I know they are good, stout little engines that last quite a long time once you get them broken in, IF you can get them broken in. Here however, they are just overpriced, usually heavy for the same size, lumps. We have too many better options and the fact that Altech is in the dictionary under Fecal Matter doesn't help any either.

Collectors will snap them up over there? Thats a good place for an engine, in the hands of a collector. I'll buy the MVVS and go fly, when I get some funds to play diesel again.

William,

these new diesel motors are ABC type(possibly AAC it's not clear yet) the .15's may be schnurle ported, the .11's are based on the very successful Enya r/c pylon racing motor. My son's version of the latter has been converted to a c/l speed motor for the ozzie class 1 speed event. It turns the 5.5" single bladed prop at well over 30000 rpm! It's aac and now has a nelson type plug head button, runs on 50% nitro. Hardly a heavy underpowered "lump"!

I'm familiar with the MVVS, a friend had one but it's performance was rather disappointing. These new ones may be improved, but the earlier ones had quality control problems. Apparently thr man that made the pistons didn't talk to the one that made the liners!

Cool pan man. Yes, I didn't think that all the MVVS engines were high output and don't have experience with that particular one, however, if I wanted to run one I could get one of them easy. Far as the Enya goes, I have to go on the limited availablity of Altech who is far more responsible for the bad taste in my mouth of Enya engines than Enya itself.

Ray,
I am impressed with your efforts and results with your Enya 11CX. Have you ever tried the Supertigre X-11 BB (not the PB Blue Head one) engine or the OS Max .11 Pylon engine, or how about the Webra .12 ABC engine. I have tested all of these engines "box stock" except the OS Max (it is still NIB). I find the Webra to be top dog, with the Supertigre a close second .... to be honest I was a bit disappointed with the Enya.
I would like to hear your findings if you have tried any of these other .11 / .12 size engines besides the Enya ..... your Enya with your mods is very impressive, THANKS!

BTW, the latest MVVS .12 ABC dual BB glow engine is highly touted, but I need to buy one to test, only about 55 bucks at Morris Hobbies. I do have one of the latest MVVS .15 diesel engines and it is a real Power House as near as I can tell (although I have done no comparative tests so far, still breaking it in). This MVVS .15 diesel is also the winner every year in the Old Timer 'A' Texaco RC endurance event ..... it always wins and usually takes about 5 or more places in the top ten finishers. The MVVS 12 diesels do very well also in this Duration event. I have never experienced any ill fitting MVVS engines, in fact the older style MVVS .15 diesel engines are highly sought after and bring top dollar on eBay ..... of course so does the older Enya .15 diesels. But that screwed-up older designed OS Max .15 diesel brings the TOP $$dollars$$ and it has a "baffled piston" running in a specially keyed and grooved (to clear the piston baffle) contra-piston!

BTW again, I do own a LOT (many, many) of Enya engines .... they are great engines! I have two of the Enya 11CX engines too, plus many of the older smaller types, .049, .06, .08, .09, .15,. 19., etc. ..... also various .29, .35, .40, many .45s, .60, etc.

I can attest to the effectiveness of Rays CX11, Rays son & my son competed for some time in the same speed class, my son running the OS CZ11P, the score was pretty even. I see from the pic that we(they) used the same prop, & I think the same model design. My take is that the CX11 is faster than the original CZ11P, & maybe the later "pylon special"(PS) OS was a little better than the Enya, but not much.

FWIW, I ran MVVS D7's in F1C (FF) in the 70's & they were pretty good, needed a little cleaning up & better bearings but they would keep a ST G15 or steel Cox conquest honest, but not in the same ballpark as a GMA tuned Rossi. What was interesting was using a flood off on a Diesel..... broke several conrods before we got it figured.The engine shut off was, well, entertaining...

I reckon that the 2bb Enya diesel could be useful - Ray, how about obtaining one & letting us know how it goes?

Dave,

I don't need any more motors!!! At last count there were over 30 .15's down in the shed. It does look cute though doesn't it!

I've been flying the Enya CX11 model myself, it gets a little ahead of me but the 52'3" lines help. We also have a OS CZ11 ps powered Arrow, and it's proving a little bit more of a handful. It did a torque roll coming out of the dolly last sunday and broke a wing. It's back in one piece now ready for another try, but I'm not sure I'm brave enough.

Donald,

the cx11 was modified internally to a speed engine by a local called Robin Hiern, I can supply his contact details if you like. The "MRS" you can just make out on the Enya lug is his business name. Robin also does a mean modified OS .25 FP for local (plain bearing) B class team racing as well. Turns the fairly mild sport engine into a rip snorting screamer. His motors in such models exceed 115 mph.
The Enya spinner etc was done by a friend who is what we call a "model engineer".

The Enya has been outclassed by the OS CZ11 PS lately. I have only really seen the enya, OS and CS 11's run in the speed class. The others you mention havn't been seen down here yet. I'm not so sure that they would hold together at the rpm that the cz-11 pulls. It is a rather expensive motor and you do get what you pay for! Recently Robin has been modifying .12 OS car engines since the .11 went out of production. They sound real promising. The CZ-11 is 1.8cc and the .12 is 2.2cc, a considerable increase in size.

I'm rather disappointed that my son decided that model flying with dad was much less interesting than football and the other attractions of adolesence. Dave's son went on to be the present junior world champion in F2A speed!

I suspect that during the early 90's the MVVS motors available down here were of much lower quality than earlier examples. I'm sure that the current model is of high quality again. My favorite is the PAW .15 TBR-GTS2 (the British Goodyear one) Both Dave and son and us used them in junior rat race. Ours held together and still runs strongly. How about a Oliver for Texaco. Powerful, easy to tune, and very economical!

Here is a photo of the Webra "Speedy .12" I was telling you about ... except for a custom Dick Tyndall "peep-hole" head which runs Glo-Bee flat coil 1/4-32 long Racing-II glow plugs, the engine is factory stock. It will turn a stock wide blade Rev-Up 7-3 prop at over 27,000 RPM. I guarantee you this engine will "hold up" to this type of RPM range .... this engine was specifically developed to Go Fast! Unfortunately it is no longer produced by Webra ($$no$$ or not enough demand). This engine was first produced as a "Speedy .10" size with regular steel cylinder / iron piston technology which was a bad as_ engine in it's own right .... I use to blow away Q-Midget and Quickee 500 pylon racing model airplanes running this "Speedy .10" engine in beefed up 1/2A pylon racers. This here later .12 size (in same case) Webra "Speedy" was the latest production unit and it uses more modern ABC technology. These smaller Webra "Speedy" engines were never $$cheap$$ to purchase. I will post a photo of the SuperTigre X.11 BB engine tomorrow night .... a relatively "dark horse" because they did sell relatively cheap (50 bucks from Tower Hobbies) and hardly anyone realizes their true potential.

Sounds like a good deal but dont forget the original and best (in my humble opinion)the good old Oliver Tiger is still available in many replica forms. I got my MkIII CS version with chromed bore from the US for $113 as it was cheaper than UK! Nice handling motor.

Mike,

I have one of these as well. Check your bore to see if it's really chromed. Apparently not all of them are!

>>>

Yes, in the current production series both chromed and non-chromed versions are made and sold, non chrome version is less expensive. Mined was purchased from Jim Booker as a chromed version but I have not dismantled it to check. Latest series has beefed up crankcase too. I have one of the much earlier series too (none of these was chromed - very nice but very tight in the bore.

I have genuine Ollies as well but use them more sparingly after breaking a lug on contact with hard ground in a profile job.

Steve,
Sorry mate, but you are wrong on both counts!
The engine depicted is the SS15 Diesel and it has a single ball-race shaft. The p/cyl is ABC.
cheers

I have an ENYA CXDS .11 diesel and the sport ENYA SS .15D diesel. Both C/L versions. Recently obtained both as part of a trade. Have bench run both but haven't done any testing. My inititial impressions are: Both engines handle well. Easy to start from new using Aerodyne fuel. The .11 is not happy unless it is really turning fast. The .15 seems to be like a typical modern style sport diesel with greater needle and compression range than the .11. This is a good thing for my purposes. Both work well with stock mufflers and are easy to prime using the pre-installed prime jet.

A fiend's son has an R/C car with an ENYA .11 CX glow engine installed. This car screams! My double ball race .11 diesel uses the same crank case and is probably derived from this car engine. Andy

Andy,

can you describe the construction of the .15D. For example is it schnurle ported? Does the backplate come off? Is it abc, aac etc.
What range of props do they recommend? Any pictures?

regards Ray

My comments on the Enya 11 diesel are given in Product review #73.

Here is a photo of the Super Tigre X-11 BB engine. It has only a single rear ball bearing, but it honks right out of the box, that is after you bore out the tiny stock venturi opening ..... it must not be over propped though. The venturi incorporates full peripheral jet induction (á lá Cox Tee Dee).

I've been outa town and haven't been keeping up. I'll be leaving again tomorrow. When I get back I'll send photos. I've not taken the .15 or the .11 apart. They are different in basic layout. The .15 is schnuerle or similar porting. The .15 might be a B.B. but I'd have to look. I've only used an 8x3 prop. for bench running both engines and I didn't tach them. Again, when I get back I'll do some disassembly, take photo's, weigh the engines, test some props and answer any questions I can. Andy

Here is a photo of the crankshafts from 4 of the engines in this discussion. From left to right is the ST X-11 BB shaft, then the Webra .12 shaft, then the OS .11 pylon shaft, and lastly the Enya .11 shaft. All of the shaft's O.D. measure 10mm except the ST which is 9mm diameter. The inside diameters are as follows: ST X-11 is 6.5mm .... the Webra is 7mm .... the OS is 7.4mm .... and the Enya is 6.45mm. The crank pin diameters are: ST is 4mm ... Webra is 4mm ..... OS is 4mm .... and Enya is 4.5mm. The Crank's counter weight webs thicknesses are as follows: ST is 3.8mm .... Webra is 4.95mm .... OS is 4.1mm ..... and the Enya is 4.5mm thick. The OS has the largest passage for fuel to enter the c'case, the Enya the smallest. The Webra has the biggest intake rectangular port opening ..... Interesting perhaps?

Donald,
yes, an impressive argument. I didn't mean to imply that the Webra lacked potential. There a quite a few small r/c motors available right now that can be converted into excellent c/l power plants.

I've posted a few pics below (hopefully!)

The first is our Robin Hiern modified OS .11 cz ps. It has a nelson type head button and all the other mods to make it a very impressive little speed motor. These were rather expensive and are out of production now. The Australian class 1 speed rules have been changed to allow .12 motors. The OS.12 car engine and the Nova Rossi equivalent look promising.

The second pic is of an oldie. It's a Tiapan 1.9cc Tyro diesel. That makes it a .11. This one is about 30 years old but isn't fully run in yet. A really nice docile sports motor.

The third is an AP .09 Hornet. This is a r/c motor with a homemade venturi and a small st needle and spraybar. The are for sale locally for AUD85 (about USD62 or GBP35) I notice that Tower sells them for under USD50. It's in a c/l 1/2A combat wing and it really sings on a small prop. Looks like a baby Rossi. I'm interested to see how long it holds together. It's real ABC, TBR, and comes with a cute adjustable muffler. Made in China but quality seems excellent sofar.

I also like the look of the Norvel .074 for 1/2A combat. (Australian and British rules allow up to .10's) Converted to a c/l venturi, with a slightly smaller model and prop it should really perform considering the claimed power output!

No argument really, just trying to share with you guys ..... actually it is refreshing to swap lies (share info) with someone on the high end (RPMs) of things! The AP engine was on the market MANY moons ago ..... it was imported by World Engines and sold under the name of S.Y. See mine here in photo that I bought at least 10 years ago ..... I increased the cylinder's exhaust timing and retarded the c'shaft timing a bit, it "honks" with small prop. There was no RC version then, and as you see it came race-ready with it's own unique Spinner and Venturi system.

Donald,

re: the SY,
amazing!! How did it hold together? I love the spinner. Did they ever make a .15?

A friend has the .15 version of the AP which has the same case as the .09. Performs very well with a c/l venturi in a sports model. Really cheap too. Hasn't had enough running to draw any conclusions about lifespan though. I notice that they don't have a high regard amongst the r/c crowd but this could be through lack of oil in the fuel etc.

There is also a superficial simularity to the CS range of small glow and diesel racing engines. I have a cs .09 diesel which is on it's third crank. I guess they are all based on the rossi layout but the knurled screwed in backplates are very similar.

Have you seen the Fora .09? Some people are using them over here for 1/2A combat. Comes as a diesel but both examples I've seen have been converted to glow. Real screamers too.

As you say, great to share lies with you!

regards Ray

I only ran mine on the test stand, proably 30 minutes total at most, it is still like new except for my mods. Yes, too bad they dropped the nice spinner assembly, probably simply a matter of economics ..... at least someone was wise enough to develop a carburetor and muffler for it so it would sell enough to stay in existence! Yes, there was indeed a .15 S.Y., but it was a totally different animal (bigger case) as I recall and it was produced solely for Speed events as it had pipe timing and might have even came with the tuned pipe included? I might run accross an old Indy R/C ad stuck in a corner somewhere ..... if I do I will post it. These engines were not imported for too very long by World Engines and as I recall, it might have been around about the time of the Great Planes buy-out? I might have seen the Fora .09 in a magazine article, not sure. And BTW, it's "SWAP lies" or "SHARE information"

Ray,
it was quite a few years ago that that I damaged my Oliver and as I had a few at that time and this was not my best running one I swapped it for an Enya 15 diesel! This is the single ball bearing late 1950s or early 60s version which I still have - very nice engine (they made this over several years in Mk1 and Mk2 versions) - and shows that Enya have been making performance diesels for quite a few years.

I do not think that John Oliver has any crankcases left now anyway.
Mike

Mike,

A mate has a mark 2 Enya diesel in a Bluepants stunter. Also
there is a very nice looking Enya .06 diesel on ebay right now. I suspect that these date from the 60's as well.
I guess they mainly service the Japanese market and that we simply don't see a lot of their products. I'm really intrigued as to whom they are aiming these diesels.

regards Ray

Ray,
quite a few came to the UK and although the power was on a par with the Oliver they never really caught on with the team race boys. I always thought that they were aimed at the American market!
