I am looking for an Old time kit that woud be good with an old McCoy .60 ignition engine from the late 40's.
Any one know of such an animal? I'm not much of a scratch builder from plans, but are there any suggestions for a plane for that .60 ignition engine that the plans may still be avaliable?
Never have been into ignition engines before.
Did they have as much power as a 2 cycle .60 engine?
Thankful for any wisdome that comes in. Jerry Bohn

Do you want a speed, carrier, or Old Time Stunt airplane?

Jim

Jim, I prefer stunt type models. I don't think I'll compete with it, but I usually fly stunt with my newer planes. I didnt realize that there would much of a choice out there.
Could you give me a close guess as to what kind of power I'm looking at compared to an average 2 cycle
engine, like a Super Tigre?
Thanks for taking an intrest and the time, Jerry

Jim asked that , more or less in the order that the engines were used when they were relatively popular. They were quite heavy compared to the usual "stunt" engines, although Hal deBolt liked to run one in his largest Stuntwagon.

Navy Carrier is the event in which more Mac 60's were used than all other uses put together. They were also used in Class "D" speed, and later in "C" when the engine sizes were changed around. I did see a RH 60 in the only ignition Viking that I saw as a youngster.

Gerald:

If your McCoy 60 is in really good condition you might want to think again about flying it. On the other hand, if it's not in good condition it wont have enough power to fly much of anything.

Collectors are currently paying $400 to $500 for a good one, even a poor one will sell for enough to buy a modern engine that will be a much better flier.

If you just want to fly an antique engine on spark ignition and gasoline fuel, there are others available with a much better power to weight ratio.

I've had a bunch of Mac 60 RH engines, I used them when I was flying C/L speed. They were heavy, but they were reliable at 18-20K rpm and did a good job, but the Schneurle ported engines have made the McCoys obsolete.

If you must fly the McCoy, and want to stay on gasoline, you'll need a relatively large plane with a light wing loading. Something like a 1/5 scale Cub. You aren't going to have sparkling performance, most likely it will have a hard time getting off the ground on a calm day - 10-15 mph wind down the runway will help a lot. You will have the power of a 0.35 glow and the weight of a 1.80 Saito.

If you are willing to run it on glow you have a lot more options, but there will still be a problem of throttling the engine, you'll have to find a large enough carb to feed it, and then a strap-on muffler.

Fifty years ago they were great engines, now they are best used as collector's items.

Jerry,

Is there an emotional attachment to this engine? Are you just wanting a challenge?

If not, you might consider putting it away in a collection or selling it and getting a modern engine to do what you want.

ASSUMING that it is in good condition, you need to get spark plug(s), coil, condenser and battery to run it on. Then you have to clean/check points, preset timing for starting position (that setting may still be good). You will have to learn how to run it, that is, how much to advance the spark once it's running (that may already be set too). Do you still have instructions for it?

To me it would be a fun thing to do. I would suggest bench-running it for awhile before considering a ship for it.

Good luck,
George

PS. I have an old McCoy .60 that I think was used for cars. In any case it is a heavy engine. The bearings are frozen in mine and it is sitting in a box...never ran it.

George, I inherited the engine from an old freind who passed, His wife gave it to me . I was just toying with ideas as to what to do with the engine, Didn't realize what it was worth, think I'll take all the advise about saving it , mabe running it once for a memorial run for my old high school flying buddy, he never had it then and I don't know why he ever got it.
Thank for the information about the old engines and planes they were used for. Jerry Bohn
