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. )

so is 54 or 56 / span . a . 40 might be more sensable . But not quite the same .

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

Dan McEntee · « **Reply #15 on:** February 21, 2016, 08:16:40 AM »

   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.

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..........

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.

Glenn (Gravitywell) Reach · « **Reply #20 on:** February 21, 2016, 11:04:11 AM »

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"

Keep those pictures and memories coming.

FLOYD CARTER · « **Reply #21 on:** February 21, 2016, 11:15:34 AM »

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.

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.

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.

Very consistent runs and not too bad looking either. Only difference with mine is a carbon muffler.

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.

Paul Walker · « **Reply #35 on:** February 22, 2016, 12:44:55 PM »

Well, for electric power, the Plettenberg is tops.
For IC, I prefer the McCoy 40 for it's looks and stunt run.

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.

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.
