Very well done 😊

dont underestimate the Cox .010 Keith, one person on youtube got a plane up to 118 mph with one! the incredible thing that allows the larger Cox .049 and .051 Tee Dee engines to go so fast is a tuned pipe exhaust, which allows them to make 120 Watts, which is rather impressive for such a small engine, when compared to electric motors that are used these days. If you think the .010 is small, then you should see the Ronald Valentine nano bee, which is an astounding .00037 cubic inches!

Thank you. Interesting. Chris.

Wonderful collection! I have a number of Cox engines, the smallest being a .010 Tee Dee. The Cox .049 was a staple at my neck of the woods back in the halcyon days of the 1970's. We built all kinds of crazy control line models, including a flying mandolin and a "German stick hand grenade" with wings. Great fun, golden memories. Thank you, bless you and stay healthy!

Keith, another great video as usual. I could watch a video of you describing grass growing and it'd be awesome. Keep up the good work.

enjoyed your presentation! I was a control line and free flight enthusiast back in the early 1960's, then sold all my stuff and left the hobby when I found girls and cars. Well decades later around 2015 I browsed ebay and got hooked again to acquire some engines and props. I don't know...something just compelled me to posses those wonderful little marvels called model engines. I found in my own experience that clean up was a chore, I had the best result with methyl alcohol in the solvent mix. And the real silver bullet for me was the use of heat, a hair dryer used to get the engine hot would free up the congealed/polymerized castor oil every time, then once you had the engine turning the solvents could reach their target much better. In this my second dive into the engine collecting hobby I found much, much more than when I was a kid back then, now I have some of the real old ones dating back to the 40's and very large displacement, even with conventional spark plugs! I never knew they even existed when I was a kid, just was focused on the popular engines of the era I was in, the ones we actually used to fly the small planes. By the way I sure do remember the cut and bruised fingers, we took a real beating using the McCoy and Fox .35 engines in our larger control line model airplanes, oh man that would hurt!!

A friend of mine that passed away last year would have approved of you wearing an engine tie pin to his funeral. He flew control line and RC planes starting when he was in high school in the late 40's up until a week or two before he died.

Interesting vid, I have owned several of those! If you run into an engine that has sat for decades and doesn't want to turn, try soaking it in a jar of model airplane fuel. The congealed castor oil will soften up and return to it's natural state in a few hours, and things should turn over nicely.

Wow, this takes me back! I recall that the Cox .049 in its most basic version, with a small tank, could be bought for just under six dollars. Double that would get you the .049 Golden Bee, with a larger tank and smart gold-anodized finish - it was a lovely thing to look at. Thanks for prodding the memories, Mr. Appleton!

Nice collection. I had a .49 engine once and ran it just because I thought it was cool. My Brother tried flying control line models when I was quite young and I always thought it was an inefficient way of making small crop circles.

Very cool. I still have a Golden bee and a Black Widow that I brought in back in 1975. Good video. Thank you

My brother used to be into model aircraft. Someone gave him one of those little spring start engines which I got to run. I dont think he ever put it in anything but I enjoyed it none the less. Memories!

the last engine with a muffler and carb is a queen bee 071 I believe, very rare and also very cool

Cheers Keith. I know you've mentioned your model aeroplanes interest in the past and its cool to see some of your collection.

Cox engines were marvels of engineering; constructed to millionths (!) of an inch. You could buy a Baby Bee .049 for $2.98 in the 60's. I hot-rodded a Tee Dee .051 for a 1/2A class pylon racer by drilling out the carb, adding a fuel pump and using 50% nitro fuel. The thing was a screamer for a minute or so and then stopped with a loud 'SNAP'. The conrod had broken and was sticking through the crankcase! Cox also made a more 'normal' cast block engine; the Conquest 0.15. All were potent and fun engines!

When you said "it sounds like a demented bumblebee" i laughed so hard the sun popped up. I would love to see them run, and as always great video Mr Appelton.

Thank you, Keith.

I own two really old .049's and a new one from Cox international. After a bit of cleaning they all ran wonderfully.

Thanks for awakening a childhood memory. I received a control line Piper Cub airplane. Neither my father nor I had any experience. He started the engine, released the plane, I made it climb and immediately descend at about 80 degrees. I think I might have made almost a half revolution.

The bees knees with a spring starter ! Look forward to seeing and hearing one run after 55 years hearing one !

This miniserie is awsome! Thank You for sharing Your childhood memories!

I'd love to see them running!!

I had until fairly recently two Cox .15s. They had a rear carburetors and a reed valve induction. Well made, reliable powerful control-line engines that were relative inexpensive. After hauling them around for 55 years it was time for a new owner. I knew of several of these large versions made into radials engines. Nice collection, Keith!

I got started with a bunch of old 0.049 engines many years ago, doing something similar (cleaning up a bunch of old gummed up engines). The number is displacement in cubic inches. A 0.010 engine is about 0.16cc displacement.

In the early 70's I had the 049 with the handle and line control. Fun memories.

Keith, what a nice collection of Cox engines. I believe the 0.010 and 0.020 were called Cox Tee Dee engines.

I think it would be a good idea for you to get every single one of these running again and make a video showing all of them, alongside your Wen Mac, buzzing away like they're meant to do! Absolutely love seeing this side of your hobbies. Always wondered what you flew when you mentioned in a comment you'd done model aircraft before; these engines speak volumes. It would also be rather neat to see you do a project combining a few 049 jugs into a multi-cylinder buzz box. Cox International is still selling any part you could ever think of for them, glow heads included, and even sells complete turn-prop engines. Where I've gotten my 049s from. You could easily source the parts you'd need to make such a creation from them, alongside any parts you might need to get your existing Cox engines running happily again.

I love this guy

I love little nitro engines. Right enjoyed that.

I have played with these my whole life. I would say the biggest problem people have is they try to use old fuel. Cox fuel is 35-50% nitro. The nitro will evaporate almost as soon as the can is open.

I had a couple of Cox engines, an 020 and an 049.

Oh yes. I have quite a collection myself ranging from a few NIB .010 to a box full of mostly older .09 and .049 from the late 70's. Anyone that's ever run these little beauties knows the pain of being bitten. I used to put a few drops of fuel into an .020 and start it while holding it in my hands.

You make me chuckle, thank you. A wasp on speed,reminds me of a girlfriend l had.

Your last engine was an 074 queen bee engine. It's a reed valve engine and it has a r/c barrel carburator. It is high compression. You had an .049 medallion throttle exhaust sleep r/c. I didn't see a Tee Dee competition engine. Cox also made a .15 engine one was a larger vision of the medallion 049 they also had the 09 medallion. It was a sport engine and throttled well was fairly easy to start. Cox also had another 15 sized engine that looked like a typical hobby engine with the block with sleeve and piston. My favorite was the medallion 09 probably. The Tee Dee 09 had tremendous power.

049 was most popular

Love the old Cox, Testor’s, and Fox. Careful with WD40, sometimes it will solve a plastic or vinyl back into the gooey petroleum distillates it came from in the first place.

They are measured in cubic inches. (americans). 0.049 is 0.8cc.

yes i have a radio control plane with a .049 cox engine on it the sound is like a mad wasp on speed.

I would find it most respectful if people showed up to my funeral, wearing an engine as a tie pin 🙂 Thank you for your videos!

They did a .15 Conquest. I have an unused one of those as well as a .09

The numbers were the displacement in cubic inches. Preferred the diesels myself, but not from Cox obviously.

Those look like TD010, TD020, TD051, TD09? Baby Bee 049 and a Quiet Bee049. Biggest hassle would be getting the Glow heads for the smaller engines. The little ones sell for good money on ebay

never planes but alot of tether cars with Cox engines but in 90's it all died down and no more track to run on

Love all your videos. In my opinion all these model engines are really diesel engines as they use a glow plug to state and compression to fire after they start. What do you think ?

I'd rather buy an Ultrasonic Cleaner. A must when cleaning Carburetors.

5:29 This is a cox .074 queen bee, the others are Tee Dee engines ( rotary valve ones )

Hi Mr. Appleton. I own a .049 Thimble Drome from a 63 Cox PT 19. Please, did you add WD40 to water ? Thanks.

Do you remember the Frog--E D --and Mills engines?

Cox engine capacities, are in cubic inches, not cc. Glow engines traditionally use c.i., and model diesels use cc - though there are exceptions.

⭐️😊👍

unless you are a know pilot for the tie clasp

That reminds me: I have 3 planes hanging from the ceiling of my garage that I haven't flown in a decade and a half. Also there's 2 full carry boxes of assorted tools, fuel bottles (some full), spare engines, radio gear, etc. I lost interest following the sudden death of my wife of 37 years and never went back. There's a standard high wing trainer, an electric (folding prop) glider and a semi scale model of a Neuiport (?sp?) WWI fighter biplane. That's a lot of 'dead money' in my current financial circumstances, so I'll have to look into contacting a local model flying club to see who might be interested in them.

This guy sounds like sir Paul McCartney

Since when are these engines 'vintage'?? I've boxes (tea chests) of these engines from my control line and rc days. To say they're vintage would suggest im beyond vintage!!! Or OLD!!!!!!. (Ps I have scars on my fingers too)
