A friend gave me an old Mc Coy 19 that seems to have very little run time on it and I'm looking for a model to hang behind it. Suggestions

S1 Ringmaster.

Well, RSM's Ringmaster Lite, perhaps. That engine was not a powerhouse . . . A 23 - 25 oz. Ringmaster would be about it's limit, IMO.

Gotta go agin ya on this one Rich, only because of the weight problem. Everyone can't keep the weight down like Ralph suggests. Ralph is also correct in that the McCoy 19 was not a power house. If it were me and I was going Ringmaster there is a good choice in the Ringmaster Jr. I have seen quite a few in my time powered by Fox 19's. Then there is the Ringmaster 307 that will handle that puppy just fine.

Get another one, and build a Twin Flight streak.

Classic legal and a blast to fly. Or, consider a Veco Warrior, another classic design for one engine.

Ringmaster JR or any of the Midwest 15 size planes. Lots of fun!

Have fun Bruce

What is the wingspan of the Veco warrior, and I was considering the Veco TOM TOM.
Don't know the spanon this one either..
Thanks for all the suggestions, and please don't stop now...

Sorry to disagree on those choices but the 19 is too big and heavy for them, the ideal model is about the size of a Veco Tomahawk. The 19 was actually a very good runner. Kind of fun to find an old model that really did benefit from using a Mccoy 19RH.
Dennis

Edit
Incidentally there were quite a lot of Flite Streaks built in the day that used the Mccoy 19, they all flew well.

Tom Rounds · « **Reply #9 on:** August 11, 2008, 03:56:35 PM »

I also agree with Dennis on the full size Flite Streak with the McCoy .19. I built many of them with this combination. I had the .19 and there weren't enough pop bottles around at the time to afford a Fox .35.

I have to disagree with you old buddy! We sucessfully flew Sterling S1 in the late 60's on the 19RH, and Goldberg Busters too.It was not a powerhouse by today's standards, but was enough power for them nonetheless.Since RSM is the only one kitting the S1 variants as of this time, I thought you knew what I was referencing. And the 19RH would be too much weight and power for a Jr..

I think Gil probably has a S1 he can stick it on to try it if he wants to...

Jim Thomerson · « **Reply #11 on:** August 11, 2008, 05:28:18 PM »

I had one on a Mackey Profile from FM plans that was a fine flying combination. Classic legal.

Bootlegger · « **Reply #12 on:** August 11, 2008, 06:50:35 PM »

Bro Jim, Tell me more about the mackey profile. This is for my grandchildren.
Thanks Guy's

Steve Helmick · « **Reply #13 on:** August 11, 2008, 09:47:12 PM »

The Mackey Profile was published in the early '60's...maybe even late '50's...and used an Oliver Tiger 2.5cc diesel for power. I think this would be a great choice (it had flaps, if I remember rightly) if built light.

The Veco Warrior is a good choice, but I'd want a stronger .19 or modern .20 or .25 to make it fly up to its potential...mine did square vertical 8's well under 90 degrees...tho it was tailheavy...with a Fox 3 bolt .19, 10x3.5 TF and Missle Mist. It needed a tad more power. The wingspan is 36".

I'd suggest a Super Clown, built light, flaps fixed, for the McCoy .19 (+ your Grand Kids). With the typical stoopid clown motif (pokey dots), it might be something they'd get a giggle out of...probably a good thing.

No place in the first post, did I see any description of which McCoy .19 we're trying to place in a good home. They're not all equal...and I can think of at least 4 different designs of Mac .19's. The late Red Head ($10) variety wasn't a long lived engine...use 25%+ castor oil fuel. It'll work well with a 9-4 prop. The NV's are easily broken, so look for a suitable alternative ASAP.

Leo Mehl · « **Reply #14 on:** August 11, 2008, 09:59:38 PM »

My choises would be Profile Shark. Jr. Flight streak or anything with about 350b to 400 Inch wing area with a narrow airfoil. Jr Ringmaster or you could even Have plans reduced to make a plane the right size. There are a lot of options

john e. holliday · « **Reply #15 on:** August 12, 2008, 07:47:26 AM »

The last I seen of the McCoy 19 Redhead was when Charley's Hobby Shop had a big box of them at $3.00 each. No instructions or box, just bare engine. We flew them on all the profiles of the day, early 60's. Would have bought the whole box of engines, but, was into combat, rat race and navy carrier at the time. My brother had his in one of the Top Flite molded kits that flew well for him. DOC Holliday

John Miller · « **Reply #16 on:** August 12, 2008, 07:55:09 AM »

Doc's post reminded me of another great possibility. Consider George Aldriches Peacemaker. Long a favorite in England. The Red Head .19 wouod be perfect for it.

Just One-eye · « **Reply #17 on:** August 12, 2008, 08:58:22 AM »

My own personal experience with the McCoy RH 19s was better than with RH 35s; we used them in planes both too large and too small for the power output. The closest to "right" was when my immediate clique was into a variety of Speed Limit combat for practice purposes, and we were using Jr. Satans at first, on suction, then on pacifiers, when we moved up to Wooten's Flite Line Demons, and they worked pretty well, but we settled on Cox Medallion 15s because they were lighter, and balanced better with the original so-short booms on the Demons.

I recall that there were Lightning Bolt 19s that had the better bushing, same as the 35s. I probably still have one of those old RH 19s. I know I still have a RH 29, but whether it's any good or not, I don't know. I got it used, attached to a built plane.

walter weatherford · « **Reply #18 on:** August 12, 2008, 02:14:36 PM »

Everyone is assuming the engine is a Redhead. I have a McCoy 19 duromatic, that I got in 1952, that is sure not a Redhead. It has a removeable front end and dual rings!! It does not have the power of one of the later RH's

OK, so we have the Duromatic, the later Red Head. The one(S) left that I know of are the hot RR racing redheads of appx the same vintage as the Duromatic (plus a few years). I THINK it came in both spark and glow. Then there was the blackhead (with a dykes ring).

Are there any more?

Jim Thomerson · « **Reply #20 on:** August 12, 2008, 03:58:47 PM »

If you are talking a first airplane for your grandchildren, I would suggest a Lightning Streak Trainer from Brodak. Friend has one of these with the redhead front intake McCoy 19, and it has served very well. I have a #2 Trixter Trainer with McCoy 19 which has done a couple of hundred training flights. The Mackey Profile is a flapped, competitive stunt airplane, which will fly a pattern better than I can. I have copies of the FM article which has reduced plan with measurements, and full size on all curved parts.

Mike Lauerman · « **Reply #21 on:** August 12, 2008, 04:51:48 PM »

I agree with the S1 Ringmaster. I inherited a scale Stinson Reliant with a McCoy .19, pre-redhead. Friend and humble self installed it onto an S-1 Ringmaster, sanded it and sanded it.
(it had been painted with Latex!) Silkspan and Aerogloss clear dope, (3 coats) and it flew nicely, climbed without hesitation through graceful wingovers, loops, and inverted.
My friend flew it for a month before building his Sig Profile Fokker DVll.
S-1 w/.19 was a superb trainer.

Chucky · « **Reply #22 on:** August 12, 2008, 05:15:33 PM »

Dad gave me a Top Flite Peacemaker kit with a McCoy .19 for my 13th birthday. I'm sure the model wasn't too light the way I built things back then, but the little .19 didn't have the huevos for my Peacemaker. I reeplaced the McCoy with a K&B .25 and the plane flew great until I drove it into the ground one time too many.

Due to its weight, the McCoy .19 is too much for many classic class A profile designs, and not enough for most .35 size profiles, like the Flight Streak or Ringmaster. Modern light variations on the Ringmaster may be suitable, but great care must be taken to keep the weight down -- so why bother. Build a Pretender (Dick Sarpolus) or a profile Peacemaker (George Aldrich). The Pretender is purpose-designed for this size engine and would be my first pick. Blackhawk was making a kit, but I didn't see it on their web site at last visit. Vicstunt.com has plans for both for about $10 ea. Both are simple models that should be an easy build from plans.

Depends on which McCoy 19. The Duromatic/McCoy 19rr is a relatively strong engine, and while it flew my Skyray, it did not fly with the authority you would want. It would fly a Ringmaster if you kept it light and kept the controls slow enough. The later front-intake Red Heads are not as strong. I would have a tough time coming up with anything better than the usual 15-19-sized models like the Shark 15 or a Jr Nobler. They are pretty small but it will fly nicely with a Max 15, McCoy 19 Redhead, etc.

I graduated from 1/2A powered planes to my first "big" engine in 1957, a McCoy .19 RH. The first stunt ship I built for the engine was a Roy L. Clough design called the "Stunt Goat" and was published in the Aug. 54 issue of Flying Models. I finished the model just as the Russians launched Sputnik, the first earth satellite, of course, I had to rename the model.
Last year, on the 50th anniversary of both events, I again built the model and Ebayed an almost new McCoy just like the one I had 50 years ago. The engine with a 9 x 5 prop and a home-made tongue muffler has a great 2-4 break and hauls this 34" WS ship all over the sky. The original was designed for an O&R .23 so the McCoy .19 is a good match, balancing out just right. This is a really good flying model and is fast and cheap to build, requiring only 4 sheets of 1/8" x 3" x 36" balsa. The magazine article had full size and 1/2 size layouts so you didn't have to order plans.
Has anyone else built this model?

Orv.

LARRY RICE · « **Reply #25 on:** August 13, 2008, 07:36:57 AM »

The "Pretender" can still be purchased from Sam Stuff and Hobbies (573) 255-3514.

May as well jump in here. McCoy stunt .19 red-heads were used successfully in a Goldberg Buster, Flite Streak Trainer and the Super Clown (functional flaps) seen here. Latter flew the complete OTS pattern with authority. Excellent little engine. Use plenty of castor!

Gene O'Keefe · « **Reply #28 on:** August 25, 2008, 07:47:47 AM »

In my way younger years I flew one on a full size Flite Streak - it flew well. Lots of good memories there. Like it was said - use "plenty" of castor oil - I'd use 28-29% and 10% nitro for a little extra kick.

Hi Gil,

I know it isn't practical for your needs, but I use a RH 19 on my Fierce Arrow 400!

I also learned how to fly inverted on a CG Shoestring and a RH 19 (same one I am using now, 45 years later! LOL!!)

In 1970, I used the RH 19 FR in a Flying Clown. Lots of fun. I still have about 6 of those motors (new) from a whole display box I bought in the late 1960's.
