Well, they aren't cheap. I'd love that twin with the red anodizing. Did you watch the video? I could even be tempted to fly one of those.... It sounded that good to me.

Well, they aren't glow so I'll limit my coments about them to this post.
Back to your regularly scheduled program....

Wiz, they still make and sell those Kolm engines. So one can buy them. But they are really good and really expensive, especially with the value of the dollar declining like it is.
Kolm made that really spectacular 3 cylinder engine that sounds fantastic in the air. But I would have to spend my son's college savings for it though. I doubt my family would let me.
:-O

Thanks G-Willie, I must have totally missed out on the heli engines when Fox was making them. I must have had interests in something else at the time and didn't pay any attention to it.

My kids are in school now. We bought them education trusts when they were young. That pays for about half of what their education will actually cost. The rest is up to them. It seems to have been a pretty good program.... But I don't think a Kolm is in the cards for me any time soon. I did get that Irvine .40 the other day, though.

Comet Foxes

Here is the start of photos of the Comet Fox engines that John Krickel wrote of in his 049 Newslettter; it helps to have a copy ofhis article. I have captioned them according to Krickels article. IE, 59-K1-1 is the 1959 .07, Krickel item 1, and the first photo of this item. Item 59-K2.2-2 is the 1959 .07, Krickel's item 2, but I have 2 variations of it, so it is 2.2, and the 2nd picture of this item. It helps to have the index handy.

This first post has the engine from my Hornet. The Hornet pictures show how the engine is mounted using diagonal holes in the beam mounts to hold the engine in the half shell until it is assembled. Once assembled, the other diagonal holes are used to help hold the car together; clever. Many RTFs have the plastic mounting bosses split from years of internal stress or overtightening or crash damage. I found I can often push and epoxy a piece of aluminum tubing over the damaged boss to hold it together. It will function as new and not split again, and is unobtrusive.

Comet Fox engnes 2

Here is another K1 engine. I have called it K1.X as I don't know how it was used. It has undrilled mounts indicating it was radial mounted, but it has one of the radial mounting tabs missing. The K2 engines are short cases with the spacer. Note one is a plain, no cartouche case and the other has the comet.

Also note the tank orientation. Comet always mounted the engine with the cylinder horizontal.

Fox .049 and .07s

As John Krickel reported, when Fox quit supplying Comet, he had a huge number of unfinished engines and parts. He modified them a little and sold them out as Fox .07 Compact Stunt Motors. Later he used the same basic parts to make the .049.

Ok, Here are the Fox .07 and Fox.049. There is a comparison shot of the .07 and .049 cylinders, may eliminate some confusion and is a good "spotter" shot. I've also noted that Comet engines have tight fitting pressed on prop drivers, Foxes are loose slip on.

Fox .07 and .049

Here are K9, K10, and K11. Very interesting is as cast K11 crankcase. If Fox started out with the old .07 mold, it follows you can take stuff out of a mold, but not put it back in. That would explain why the old "dishpan" is still there! The .049 FAI must have been a new mold.

Comet Foxes Final

Here are all the case markings Krickel speaks of and can be used by collectors for ID. Note on K5, the Fox .07, you can still see remnants of where the Comet was ground off. The "bump" on the .049 case, K6, is sure hard to photograph.

Please note that although this series of pictures are all my engines, the original descriptions are all John Krickel's. John's marvelous small engine research is just a fraction of his engine work. Tim Dannels ( www.modelenginecollecting.com ) still has most of the back copies of Engine Collectors Journal available very reasonably where you can see more of Krickel's reports.

And don't forget, MECA ( www.modelenginecollectors.org ) is the group of folks who research and maintain engine history.

also some helpfull advice for guys using the .07 rc with the optional tank mount

you will need to add very thick handmade gasket to back of engine or shave a couple hairs off inside of most of those backplates when adding to engine because they will sit right on the back of the crank pin and hinder motion

I still have a couple of NIB Fox .07 RC engines myself. I am planning on using them one of these days, but it hasn't happened yet.
