I bought one of these with a stunt model plane back in the late fifties. My first control wire plane. I was eleven at the time and a crowd of friends gather to watch me fly it the first time. I made it a half lap before crashing, destroying the plane and bending the prop shaft of the McCoy 35. I was the only one there that didn't think it was funny.
I still have an almost virgin unit still on an airplane I built in the 60's. The damn thing would sometimes run at home but always failed to start at the field! It always back fired more than any engine I own and spin the nut and prop off. The last time I attempted to fly it the nut and washer disappeared never to be seen again! I ended up mounting my old green head k&b 35 back on that airplane. The k&b was old even when I bought it used as a kid but it always ran great!
Nice job on getting it back to its hay day! I’ve had a few Redheads and Fox .35’s. The major flaw in the McCoy is the lack of a bushing on the connecting rod. If you were a little lean and pulled up into a wing over or loop it would blow out the rod. Even if you ran her perfectly that rod was short lived. I heard of a guy who would put in a bronze bushing into the rod but it’s been awhile. CL engines are getting harder to find nowadays. I’m thinking of turning my own venturi’s and converting RC to control line. Funny, back in the day we would take thumb tack heads, file them to fit the Venturi, silver solder a control arm to the head and we could throttle control the engines on the early RC models. Guess I’m backward engineering things now!
I bought one of these from a high school acquaintance in 1968. I may still have it packed away in storage. I used it on a control line Ring Master back in the day
Almost hit flying power. Nice motor. I guess I'll blow up a few before I get over it. I think they are built strong. Dick McCoy lived 100 years if I remember right. I saw his kid, he was an old man then, hahahahhahaha. Thanks a million, Paul in Thailand.
If you are going to flip a motor by hand, the compression position is important. A 2 Oclock position is best (to protect your fingers) Random compression postions will get you whacked more often than not. The motor is a lot quicker that our reflexes.
I have one I converted to R/C back in the 80s . Has vice marks on the mounting lugs so everyone told me it's junk. That's fine, it runs perfect and flown several planes. I used a carb from a Veco and Tatone muffler. I think I have a Blue head 29 also. Anyway I like those old McCoy engines!
@barnfres60: Thanks for the compliment mate! :) Yes, the glow plug clip is a standard unit. I too have had some troubles with the newer battery powered self contained igniters. Perhaps the dimensions of some of the newer clips do not match the size of the glow plug well.
you are running it way to rich turn the screw in a lot more, ive been running them and still have four since the early 60s and they still run. about 1 and 1/2 turns.
Where'd you pick this up? Assuming it wasn't just sitting around in your garage. My dad had a couple of the old McCoy redheads. I'm thinking they were pretty inexpensive back in the day.

Man, you need to lean that bad boy out and get her screaming!! I have a McCoy 19 redhead that I use on an Akromaster.....it really wails!!
Yeah, I was just worried that it being a sort of antique that I might damage it if I leaned it out.

Nice, you cannot beat the old mccoys or fox engines
Thanks for your comment. I love the older Fox engines also.
I was flying control line line models in the 60s 049 Cox. 35s were the bomb.stunt master kits with real silk and dope. Amazing memories.

Nice engine !
Thanks bud. The fuel is FAI with extra castor so it is about a 25% ratio.

I had one of those in a Frog Attacker when I was 16 , Great engine , Lots of line tension
I just looked up Frog Attacker and found plans and photos. Neat airplane! :)
@roosterinboro It was given to me by a club mate. Actually, I think it had been sitting around in a garage for decades!

+ronald miller Yeah, I was running it rich on purpose.
I use to own one of those. I had it on a Flight Streak Trainer by Top flight.
Hi, thanks for the comments. Do you still fly them?
Tom, that engine seems tight for a red head.
Like in a good way? :)
Maybe it was not run much in the past.
yes. in a good way. With lots of castor it will last. I still have mt 1953 red head and two 56 red heads, so far they're not clapped out.
Where'd you pick this up? Assuming it wasn't just sitting around in your garage. My dad had a couple of the old McCoy redheads. I'm thinking they were pretty inexpensive back in the day.
@dsldrvr69 No sorry, I do not know where you would be able to buy gaskets. I usually just make my own.
I must have had a bad McCoy 35 red head, mine fell in the category sometimes start.
check ebay sometimes you will find the gaskets.
wow! super cool old engine what fuel mix are you useing? and can i use heat as the methanol?
