Hello All:
I have a Fox .60 engine that has two glow plugs that are angled in the top of the engine, a single ring, a bolt on carb that is vertical, twin ball bearings and a brightly tumbled case. It is a RC engine
Any idea as what model engine this is?
Tia,
Frank

What you have is a 1966-67 RC .60. The head is - was blue in color.

Hi Phil:
You are correct! The engine is a 66-67 Fox .60. I think that they may have had needle bearing on both ends of the rod.
I sent it to a chap named Scott Reise in Portland. He cleaned it a bit and got it running. It was frozen into a ball of nasty corroded metal when I sent it to him. He claimed that it started on the first flip and had a ton of power. It has two rings instead of the single ring that I mentioned.
If you are looking for an engine man that is fast and inexpensive, contact Scott! I can not say enough good about his work or prices!
He has has my McCoy .35 Red Head that has very little compression. I am anxious to see what he can do with this engine. I got it for $5.00 and I thought the prop, glow plug and nva was worth $5.00. It is the Lighting Bolt model with the elongated front mounting holes that may interchange with the Fox .35 Stunt.
Stay well,
Frank McCune

Scott's tongue mufflers are simply the best!

The angled plugs stumped me as supplied from the factory, the plugs are vertical. And it uses a standard long plug on the exhaust side and a short plug on the intake side. The plug on the intake side sits directly over the baffle and a long plug will hit the baffle. This engine morphed into the Fox 78.

Hello Bill:
Thanks for the information re. the Fox .60 engine.
Scott told me that someone had placed a long plug in the engine in lieu of the short plug and it had struck the baffle. Since first seeing this engine, I have seen pictures of the glow plug arrangement. One thing for sure, Duke had a way with engine designs.
It was great getting to meet you at Lebanon. What were the chances that I would find you out of all of the people there on my first inquiry? Lol I should have bought a lottery ticket that day.
Be safe,
Frank

See you at Brodak's?

Hi Bill:
I am attempting to talk some of my colleagues into a day trip to Brodaks. I doubt that we could find lodgings near there but perhaps we could drive a bit to find a place to stay.
That area is my old stomping grounds as I worked construction in that area while I attended CSU.
If I get there, I will be sure to look you up and perhaps see your book about engines again.
Stay well my friend,
Frank

Getting back to the Fox .60...Duke made an "Eagle" and a "Hawk" .60 sometime in the '70's. The Eagle makes a pretty good stunt engine. It has a monoblock construction (fins integral), while the Hawk has steel fins/cylinder like a K&B Greenie. I've seen or owned a bunch of Eagles, and all had a bare aluminum cylinder head. The Hawk is said to be a much higher powered schneurle ported engine, and my recollection is that the head is anodized red on those. The prop driver on the Eagle is steel, but on the Hawk is anodized aluminum...and they swap. Both have the flanged venturi/throttle, and Fox has/had CL venturi/NV setups. The Eagle would be a pretty good ST .60 substitute, and the Hawk would be useful for Nostalgia Navy Carrier, I'd guess. I'd like to see a picture of Frank's engine. H^^ Steve

Here is Frank's engine, and Eagle 60, and a Hawk Frank can confirm this is his engine. Also the .74 RC, the .78 RC, and the final 78 RC. The .74 was a bored 60. The .78 was a stroked 74. The .78 had a 1" bore and stroke; displacement is easy to calc; .78 x 1 x 1 x1 = .78!

WOW Great INFO Guy's. The hard thing to refurbish this engine is making sure the the needle bearing's are put back correctly. They go between the crank pin and the con-rod. SMALL fingers are good. Thanks for the kind words guy's.

One tidbit about the Eagle .60's I remembered. I have three of them, two are the same, but one is different. I noticed that while the mounting bolt pattern is the same, the distance between the beams are different, and the backplates don't interchange. The bore for the backplate is bigger on one of them, bigger BP bolt pattern, etc. Everything else seems to be the same. The reasoning wasn't apparent, but maybe easier assembly. They're all apart and I haven't attempted to reassemble them yet. Maybe tomorrow. Nope, going fishing... ;D Steve
PS: That one with the blue head is kinda pretty!

More Eagle 60 tidbits. The 1st Eagle, 1972 had only muffler lugs above and below the exhaust. The head had what looked like gang slotted fins, shallower and finer than later, and the circumference was polished, not as cast. 1973 was the same, but had a head with cast fins and circumference.
In 1974 the exhaust valve was eliminated, muffler lugs were added ends of exhaust stack and the bottom of the rod was bushed making it larger. If you look inside the 72 or 73 case, you'll see there is about no clearance where the bottom of the crank misses the case on the right side; in fact the cast may have been ground here. Now look at the case of the 1975 Tower Sport 60 ( a 1974 Eagle clone). You'll see a fillet has been added under the stack and into the right mounting lug. This allowed for space inside the case to clear the new larger rod end. Look at the 72 and 73 cases in this area and you'll see the fillet is missing.
Now look at the 1978 Export Eagle. The head is obviously changed with the plug vertical and moved toward the exhaust side. A picture shows the deeper protrusion for much higher compression for running on no nitro fuel. But look at the fillet area; the fillet is shorter and no longer intersects the lug. That is because the bottom of the case is thicker and larger in diameter. This change was actually made in 1977. This rear cover is larger and won't fit earlier engines. The 1980 Eagle, the last one, was like the Export, but had a little lower compression and Fox's new MK-X carb.

Easier to see case changes here
