McCoy engines

My Feedback: (16)
I had a George Aldrich version of the McCoy 40 Blue Head Stunt at one time. I liked my Johnson Stunt Supreme and ST G21-46 better. I just sold all those last year. I also had a Fox 40 Stunt and a Merco Black Streak. The Merco was pretty but that was about it.
The 2-4 break is pretty much a thing of the past for modern day stunt but the old McCoy Red Head Stunts, OS Max S 35's and Fox 35's sure did a good job of it.

For those interested, I have a NIB Series 21 Testors McCoy 19 engine - mine has the Dykes ring (maybe they all had a dykes ring?). I dont intend to ever run it, but to me it is an interesting curiosity if nothing else than the strange squarish looking crankcase. It has a really nice Perry carb installed.

Your right, and cadillac has been in production for 100 years but they aren't cadillacs anymore .Same with Corvette. 50 years but when you buy a corvette it really isn't one because they changed them over the last 50 years.

I would agree that the Fox was the better stunt engine of the period. I would not, however base the choice on period of production. Many fine engines did not stay around for long. Johnson for example.
I also seem to recall that the late George Aldrich said that the McCoy was actually a better design than the Fox but was hampered by quality control matters.
BTW, I think the Redhead was made until '71. Those
from 1966 onward had lightning bolts on the case. The "Lightning Bolt" models are not legal for Foxacoy, though I don't think there are any internal diferences.

The Fox 35 Stunt has been in continuous production since 1948. That's 58 years. The McCoy red head stunt was in production 11 years (57 to 68) Now which do you think was he better engine?? The Fox also won 100's of stunt contests, the McCoy just a few and that was because Ed Southwick used them and he was paid to advertise them.

My McCoy .35 Redhead has the lightning bolts cast into the crankcase. It ran just like the previous versions, as far as I'm concerned.
I bought my last McCoy .35 in 1969 from America's Hobby Center. Then I switched over to K&B Stallion .35s. They were selling for $11.95 in 69. I used to order two or three at a time.

Ed, The Type 21 does have a dykes ring. Looking was no problem, finding was. I have boxes full of old engines in my basement that I've collected over the years. Some day I'll have to dig through them and label what's in each box. All the really collectable stuff is displayed or in shelves or places that they can be easily seen. The stuff in the boxes are pretty much run of the mill engines. I have one 4 gallon fuel box full of Cox 1/2 A stuff and another full of the Cheap McCoys. I was going to sell them on ebay but never really had the time. Takes forever to list them one at a time. Most aren't worth the effort. I Used to give the 1/2A stuff to the local kids but it's all video crap now and no one plays C/L like when we were kids.

Ran one of my Redhead .35s this afternoon. I will confess to a bit of bias aganst the engine, having used so many of it's competititors years ago but it fired up instantly and ran well. I must say that I think the (tapered) needle was easier to set than the (stock) Fox .35.
The light was poor for my inexpensive tach, but it got about 9800 0n an old 10-6 Tornado wood prop with 5% nitro, 28% castor.
I purchased this engine a few years ago and do not know it's history. It seems to have been run a bit but not abused. It has the offset plug but is pre- lightning bolt.

Loughbd said the Fox 35 had been in production for 58 years. That statement has been completely refuted in earlier posts.
But there is an engine currently on the market that has been in production for more than 55 years. It has been made under two different brand names, but the parts from the earliest ones will still fit in the latest, and parts from the latest can be used to repair the earliest ones.
See pictures. A 55 year old Veco 61, and two brand new K&B 61s.

Cool Will...
Curious though...is that an r/c carb on the 1951 model?
I can't imagine that was a very big seller back then given that r/c was pretty rare indeed at the time.

Oops. Gentlemen, I erred. The time should have been FORTY-five years.
Race, yes that is n r/c carb on the Veco. It's an air bleed type, incidentally.

The Fox changed over the yrears and so did the K&B/Veco. Try and put the ringed piston in the ABC cylinder. The needle is now in the back and it used to be in the front. there have been several different Carbs and the parts from a K&B Carb will not work in the Veco carb. Just like the Fox it evolved but it is still the K&B61 and the Fox is still the 35 Stunt

the Cox Babe Bee 049 has been in production for 50 years because it came out in 1955. Just because there have been changes to an engine doesn't mean it hasn't been in production since it was first introduced.

The Veco 61 did not come out until 1965 and then it was only given to a few competition fliers. Wasn't sold to the general public until 1966. That makes it 40 years old. I remember well because my Dad's friend Ralph Brooke got one of the very first ones.

Wrong on the date? I'll allow that, but you are wrong about the ABC engine. The RINGED K&B 61 is still in production, and all the mechanical parts still interchange. Carb? The carbs were obviously different in the two pictures I posted.
The Veco 61 and the current K&B 6550 engines are still the same.
There is one internal difference that has no effect on parts interchange. The earliest Vecos had a plain skirted piston, but before K&B took over the design auxilliary bypass ports were cut in the piston skirt, with matching ports in the cylinder sleeve. Adn one more - the earliest Vecos had a Dykes ring. See picture.
But the sleeves and pistons still fit one to the other.

Bill,
This is not about McCoy, but instead, Veco. After reading your comments on several forums, I surmise that you are very knowledgeable about older engines. I grew up flying with O & R, Fox, Veco, K & B, etc. and still have a number of them. I'm in the process of cleaning up and rebuuilding some of my Veco 61's, and need some gaskets including the head shim. Do you or anyone else reading this know where I can find these?

You might find that some of the modern 60's head gasket will fit the K&B 61. As far as gaskets go, they aren't hard to make. I use a stamp pad to put the outline on the gasket material and then use a REAL sharp number 11 exacto to cut it out.

As stated, the parts for the K&B ringed 61 will fit the Veco 61 Just order the head gasket/shim for the K&B 6550 engine, and you have what you need.
As an alternate you can cut one from an aluminum drink can.

Bill,
Thanks for the info on the Veco. After reading your e-mail I tried your suggestion of cutting a head shim out of a drink can but the drink spilled out and got me all wet and sticky.

Bill,
I have several McCoy engines ranging from early 50's to late 60's. I'm going thru them and cleaning them up, getting them loose and lots of lube. Some have red or blue heads. I want to give the heads a fresh coat of paint. Do you know of a matching paint in spray cans? The red, I think I could match, but the blue is about gone and not enough left to get a match.
Also, do you know of a source for parts for .19, .29, & .35. All of these are the ones with cast fins and heads prior to the Testor days
Any info would be appreciated.
Thanks,
Richard

Sorry, I know of no parts source, nor do I have a match for your paint.
Some of the Testor's engines, esp the "Red Head Racing Engines" had anodized red heads, but the front and rear covers were still painted.

Bill,
Thanks for the fast reply. I have 3 ST Blue Head 61's that I would like to get the heads anodized. So far, I haven't found a place to have it done. Do you know of a company that could anodize these heads?
Thanks, and have a great weekend!!!!!!!!!!
