Other than the ugly RC carb on it, I personally think the ST .51 was the most beautiful and perfect stunt motor made. From the first time I saw one back in the early 80's, I wanted one. Not to be of course because they just cost way too much for me. Anyways, I recently saw a picture of one and it got me to thinking what others considered the most perfect stunt motor.
So fellow hobbyists....what do you think is the most beautiful and perfect stunt motor made? And remember, there are two criteria....
1. beauty
2. perfect stunt run.

Beautiful blue color and perfect stunt run everytime.
Other than that the SuperTiger G21-46 is/was a great stunt motor. Got one on my old time stunter.

Hmmm, well being that I'm both financially challenged and my patterns semi-suck, so... well I've recently developed a crush on my OS Max-S .35 with an aluminum Zambelli venturi and no muffler. That's for my lighter weight Goldberg Shoestring. It growls a 4-2 break like Swiss clockwerk. And for the bigger Cardinal, I hate to be common, but I kind of like the LA.46, no break, just steady smooth authoritative power.
Hope I didn't set the bar too high, Lol.
Rusty
EDIT: Oh, I missed the first criterion, beauty. My LA is blue, hope that doesn't disqualify me.

If your neighbours are connoisseurs of classic sounds , and live within 2 miles , theyll appreciate the aural delights of the 1958 FOX 59 .

probably a capitol offence to use one for Combat these days . Is Aeromuddler .15 plan @ 150% as the spars work out to be four foot ( 48 in. )
(http://www.outerzone.co.uk/images/thumbs/plans/1633.jpg)
so is 54 or 56 / span . a . 40 might be more sensable . But not quite the same . ;)

RO JETT 67

Ro Jett .61 with the BB mods and Brian Eather props and pipes. Darn near as consistent as any unemployed drone motor and actually sounds like a real model airplane when in use.

I have been running the same engine since mid-2007, and once I discovered the effect of the various blends of fuel types, it has been nearly magical, particularly in heavy air. Always the exactly the right amount of power at exactly the right time.

Hi Glenn,
Great post!
That st .51 really looks like the rotax engine in my 1970 skidoo ;)
I find the Brodak .40 looks great and gives a perfect stunt run.
Any of the enyas are also beautiful engines.
Cheers,
Dan
-
I'm fond of the ST G.51 but I believe they didn't appear until the early 90's. I had one in my first Shark.45 that I took to VSC in 1994, and they were new to Tower Hopbbies/Great Planes at about 89 bucks each. I think Gerry Phelps showed my the first one I saw at a Chicago area Fermilab contest. It's been my main engine of choice since them and have collected quite a few.
Type at you later,

That plan of GMA's English Peacemaker takes me back to 1960, when it was the first really aerobatic C/L model I ever built. It was powered by a (borrowed) Allen-Mercury AM35, a neat, lightweight, plain-bearing 3.5cc (.21 cu. in.) diesel that ran beautifully on a 9X6 nylon prop., never missing a beat, never sagging in the overheads and starting with a couple of choked turns and two or three flicks. No silencer, but we flew within a hundred yards of a cul-de-sac of ordinary homes and nobody ever complained - except once when we were still flying at nine o'clock at night... Perhaps nostalgia isn't what it used to be, but it's pretty good all the same.

I have to go with Brett and Ted. The BSE RO-Jett (any size) is a piece of "Jewelry" in my book having owned a couple of them. But I stupidly sold them.......... ???
Jerry
-
Does it have to be a CL run?
Since no one answered,I am just going to post this. For me this is the greatest. I happen to own 2 of these, so I know what I am talking about.
Second, I would have to agree with Bob Reeves. The Saito's are a joy to behold and use.
-
Any PA. Of all the PA's I've run so far, the 65 is my favorite.
-
wow....there are some really beautiful motors out there. I've never seen a Ro-Jet before....stunning! But I have to stay with the ST I'm afraid....its beauty is just too ingrained in my head. The ST .51 is one of those things that I have drooled after for so many years that it has become one of those untouchable dreams. "Heavy sigh" ;D
Keep those pictures and memories coming.
-
I can't exactly call the ST 51 "beautiful". Mine came from Tommie Lay, and performs perfectly in a Brodak Legacy.
I complained to Tommie about that "over-the-top" cylinder head, and we discussed machining it down to a reasonable size-both to save weight and to improve its "curb appeal".
Tommie also advised me to scrap that ugly stock muffler, which I did in favor of a lightweight tube muffler from Mr. Dinger.
Well, the ST is hidden under a cowling, so I don't have to look at it.

How about one for Old Time Stunt?
A really pretty engine.
Anyone know the size?
Bob Z

I will vote for Lauri's engine. The photo does not do it justice. His engine run at the 2014 Championships was superb.
For Classic engines, the OS 35S should be at the top of the list.

Jett bar stock

Robert Z. That is a Cunningham Blue Streak .64 cuin.. Uses the same piston/cylinder as the Orwick 64. Probably made by RJL. The Orwick is actually nicer!
-
How about the Marvin Miller version of the Anderson Spitfire, or any of the originals as far as that goes.
-
Sorry, Guys - the color fooled me. I thought it was an Orwick.
Floyd and De Hill set me straight!
Anyway, here's the Orwick.

The new K77 from Kaz Minato. Promises to be a great stunt powerhouse. Mine has run on bench only but will soon be in a Trivial Pursuit.
Very pretty in my humble opinion. 1/2 oz lighter than the PA75. One shown is with muffler mine will run with pipe.

What's the matter with you guys? No contest here. This progenitor of stunt motors has got to have won more stunt contests than any other. And, pretty is as pretty does................... ;<)

Of the stunt engines I own. The Stalker .51re is my favourite.
Very consistent runs and not too bad looking either. Only difference with mine is a carbon muffler.
-
I was wondering how long before someone posted the Fox .35! I always have a smile on my face when I see one. Always good memories. H^^
-
The ST 51 from Tom Dixon has one of the best runs I have.
-
Whew....I was beginning to think I was the only one! ST .51 forever! %^@ H^^
-
At the time it was the $10.00 McCoy Red Head .35 in a plastic box, blue base with clear lid. It was also my first .35. Next was the Green Head K&B .35. I was in my 20's when I got my first of many Fox .35 Stunt engines.
-
Well, for electric power, the Plettenberg is tops.
For IC, I prefer the McCoy 40 for it's looks and stunt run.
-
Of the motors that I've run, the 46LA. Because, blue (well, that and only having run cheap engines).

Are you still using the Pletts ? I thought you had switched to the Power32.

If it's one thing I wished I had gotten into, was some Stalkers. I would have loved to have at least one side exhaust version.

Silly me, I like my L&J Ceramic Fox .35 (actually, the only stunt motor I own) n~
-
I've always wondered....what makes a Ceramic Fox a Ceramic Fox? How is different?
-

Ceramic coated liner - lasts much longer, modern fits, and lighter with an aluminum piston and aluminum liner. Should also vibrate much less due to the lighter piston, but I haven't actually paid close attention to the few I have seen. Done correctly, should last forever
I would be interested in anyone's reports on the engine, preferably someone with experience with competitive stunt engines (from 2016, not 1955) because it sounds like a good idea.

Well, I ran a Cobra at the Nat's. Shortly after I returned, the bearings went. I replaced them and they didn't last long.
I had run the Scorpion earlier in the year, but the bearings in it went.
I was forced to switch back to the Power 32 as other than a occasional bearing going, it worked fine. Their bearings are not expensive, and simple and quick to change. So I used a Power 32 at the Team Trials.
I am now using Plettenberg's again. I still have the original ones ai used from late 2006 and they still work great.
I have used the Orbit series, in sizes from 30 to 25 to 20, and now 15. The Orbit 15 weighs 1 ounce less than the Power 32, and powers the plane no differently. No significant inefficiency using it the way I have to.
They are works of art, and cost like it though! If you use one, you better be serious.

Paul,, if you are using Plettenburgs again, why not the Predator H^^ instead of the orbitLOL,, I mean hey, you fly a Predator,, with a predator right,, how perfect would that be

The RO Jett .76 is by far my first choice. I am, however, aquiring this little gem to play with. It's a Russian Zeus .61.

Although used by many R/C modelers in the USA, this little puppy is known a bit better on the other side of the Pond.
The Jen engines can be purchased with an OEM venturi.
I'm building a model around the Jen 57 currently. #^

From a box of engines I unpacked from around twenty years ago.
Anyone ever run one? ??? ???
Bob Z.

We used to run one at Ward Hallenberg's house the day before the Model Engine Collector's Association Collecto held in Tulsa.
It didn't have the power of a Fox .35. The rod assembly would break after 20 or so runs.
Wild Bill Netzeband did a writeup on them in the 1960's. (The rod broke on one of his)
-
Thanks for the advice, De.
Mine is new, never mounted or run.
I guess it will get donated to the museum.

You must have "Lots Money" to be able to "Donate" a $600 engine to a museum! ~^
The last one that sold on Ebay went for $613..........Wish I'd bought a few of those when then first came out. Who knew? ???

A dear friend of mine who flies RC has one in a large Citabria, I think his is a >90 size? it seems rather less than stellar power wise,, I would put it as a decent .60 size,, it seems to be getting a bit better with time, but still no powerhouse, but it fits really nicely in the cowling
-
The Aero .35 was the only engine produced by this company. Your friend must have an engine produced by another manufacturer.

Bob Z.
Well, I was present when a friend ran one sometime in the early 70's I think in Denver Colorado. The guy owned a small hobby shop in Englewood CO and I built several combat ships for him. I was fresh out of the Army and looking for a job.
He ran the engine on a bench in the back of his shop. The engine was brand new and was hard to start but eventually start it did and ran for about three minutes. I was using about a 9-6 prop as I remember but not sure about that now. It ran rather unspectacularly and I left shortly there after.
I actually saw one at the flying field in Miami Florida a couple of years in a CL Scale ship. It was a mustang about the size of a Jetco Mustang but remember the guy seemingly got a little miffed when I asked him if it was a Jetco Mustang, and he said "No Way" and walked away from me. He didn't run it or attempt to start it!
That's the sum of my experience with them.

While I've only run mine on the bench so far, I have to agree Tom. It runs very smooth but very different than the rest of the RO Jet Stunt engines I have. A little more like a European engine. Lower RPM Growl. I'll get it in a plane soon if I can get finished with the Eye surgery and dental work and other medical crap that's been occupying all my time of late.

You are most likely correct, it looks like the same layout, but its definetly NOT a .35
-

I've stared at the exploded view of this odd thing, trying to understand it, till my eyes hurt. But here's proof, it's about all I could find, but it does run, sort of.

That sounds like one of the (several different) British designs by the outfit that made the rotary cylinder/geared things from just maybe a decade or less ago. You may recall Mr. Powell using one of their engines for a short while. It puked, if I recall correctly. Maybe multiple times? They were called "4-cycle" engines. I didn't understand why they worked at all, but I do know that gears are a short-lived deal at very high rpms...and 10k is relatively high for gears. I haven't seen the ads for them lately, so expect they're defunct. D>K Steve

Aeromodler has an in depth article this month on the Aero .35 and another in line engine. Very interesting. I remember seeing The Aero .35 in a local hobby shop in 1950, but it cost nearly an average weeks pay, and was way out of my meager funds then.

That carb isn't as easy to set as an OS, but it's a beauty once you get it set. My son has one on an R/C 40 sized Spitfire, plenty of power on a 6 pound Scale ship so it's great for two types of model flying.
I have two Tom Lay 51's and hope to use them in the near future now that I'm in Stunt Heaven.

I am truly surprised no one mentioned the perfect stunt engine, the Aero Tiger .36 by Randy Smith.. Consistant one flip starts, the power of a .46, light, strong, compact, and not bad looking. Fuel efficient as well. D>K
One of the best 4-2 break engines ever made, and extremely useful.
