- Having lost my first .010 engine in the fire, I finally found one to replace it. Here I take it apart, clean it, and tighten the Piston to the Rod ball with a special tool. 14 grams or 1/2 ounce made it the smallest production engine in the world. 62 year old technology! See it run. For parts and engines, see www.coxengines.ca
These are lovely little engines. I have an original red 010 in a plastic case, and never run. I purchased one of the later black Cox 010 engines which is a real screamer. I have a collection of over 200 engines, mostly 'diesel' or compression ignition engines including a 1/20th cc Valentine engine from Germany. My Dynajet pulse jet is from the 1950s but I have never had the courage to fire it up. Thanks for the video mate.
That is a good collection for sure. I never had luck with my dynajet. It was always iffy to get it started. Thanks.
I am 64. Thanks for the memories. Cheers!
I am 75 and trying to keep the memories. Thanks much, Kevin!
My second ever cox engine is arrivng tomorrow from Canada. Following my first by about 42 years 🤠. This one is the .049 cruiser. Installing it on a WillieNillies model. My first build.
Way to go. That is a good reliable engine, so it should be fine. Have fun and happy flying, Bret.
My first build was a Sterling Citabria with an 020 PW around 85'. My old man had the real thing in the identical paint as the one on the box. Mowing lawns just couldn't finance a Canon so unfortunately it became toothpicks ala free flight 🫏💥😭😂
super cox fan here, funny just did the same thing to my .010, still havent run her yet though. but after just paying $84 from sig for a gallon of fuel shipped think ill run a tank or 2 and save the rest to fly my .049's. great vid mr herbert. always happy 2 see a nightflyer upload
Right on. Gee I'm only paying $69 a gallon, but for 20% from Torko Racing fuel. I know Sig is great fuel too. Thanks for being a long time subscriber and know I appreciate you. Happy flying and thanks so much!
Thanks Dave!, Great memories, great video! Still hard to believe after 60+ years that something as small and weights less than 1/2 oz. can turn a prop 1 full turn, 450 times in one second ! ! ! .... incredible ! ! ! ... Happy flying, be safe and all the best. ... George
Hi George and thanks so kindly for commenting. That was a great perspective! Happy flying to you as well.

I only messed around with the .049's but your video brought back some great memories! That .010" really spins!
Oorah and Semper Fi to the best RC pilot and mechanic in the world..!
Thanks kindly Bud, especially to hear that from an Artist like you. Semper Fi.
Great video Dave, I love the old Cox engines. My first was around 1977 from our local Kmart store, was a P51 Mustang control line cox powered. An old friend learnt to fly helis with an Hirobo Shuttle and helped set it up for him back in the day. I had the Kalt Baron Alpha 30 heli. Cheers from Mike in Perth Western Australia :)
Thanks so much, Mike. Great to hear your story.. Happy flying and Stay well.
😂😂 brother just the other day I came across my identical TD as well as two 020 PW'S, an 020 TD a 1/2 dozen 049 PW's, about 3/4 of an 074 QB and an 090 TD. Remember those ones?! With the aluminum collector and pipe? 😂 Sure u do u probably have 5 of each lol. I also found an unopened tin of cox 30%? I think from the 70s it's a blue can with a dark plane silhouette. 😄 I remember the 2 tiny ones actually approaching first flip starts and semi tuneable reliability once I got me a tin of 25% Anyways thanks for the show man, it seriously engaged a mystical state of clairolfactance 😭😂 I'll be digging it all out in a month or two, I've probably got some things you'd like if u have any interest. Cheers
That is great. I only wish this .010 was not lost. Pretty rare. Sounds like your another Nitro lover, and that is good to hear. Thanks much.
I mentioned to a cousin that's a jeweler here in Iowa that they used to make these into tie tacks back when I was a kid. He thought it would be cool to own one and wanted me to see if I could find him one.
A week into that rabbit hunt I learned they were scarce and even if I wanted to make one from an engine; those engines were now selling for crazy money.
I can get a Co2 powered motor that's even smaller for less money which is a bargain considering the skills needed to make such tiny components.
I seem to remember a version without the tank in the back but I haven't been able to find any. Maybe my memory ain't as good as I thought?
I never messed with the CO2 motors so can't help you there. As you saw, I made Key Chains and had the Pistons Gold Plated, So tie tacks sound cool too. The 010 on Cox engines international has a price tag of $395, so I passed on that too. Good luck with finding an engine and stay well. Thanks much.
Cute little thing, seems to work fine.
Just needed a little cleaning up. Thanks.
Those little engines were screamers! They liked to run best on 25% nitro fuel. Great video.👍
So true. Thanks kindly.
Fascinating little engine!
It sure is. Thanks Robert.
40 years ago I took a 049 and filed down the glow head and cylinder to raise the compression, drilled out the air inlet and needle hole and mixed up some Missile Mist with everything I could find that would burn to fuel it. There was some alcohol, acetone, gasoline and some regular oil mixed into the nitro fuel.
Amazingly it screamed so fast it was almost inaudible. I had to keep the fuel bulb I was using connected to the filler because it would empty the tank in about 10 seconds of running. The cylinder was glowing red from the heat and almost melted the glow head.
The good old days.
Glad it worked out for you! I’m glad you won the bid!
Me too. Thanks much.
Back in the mid to late 80's I ran a 051 with an aftermarket carb and it was great, having full control of the throttle gave my little plane a good life. Giving me more air time than any of the .40 size planes I built and flew. I always compared everything to the QTee. With the tiny radiiogear
Good memories! I had 1 on a 'pop bottle plane'. 1 liter mtn dew bottle, yank n bank!
Haha. Right on. Thanks.
Awesome to see this vintage engine run again. Also cool to see you got your hands on another Hirobo Shuttle vintage helicopter looking forward to seeing it in action once the weather gets better on your end Dave?
I was doing good till last night when a deer jumped out in front of me and hit my car. Now I have that to deal with along with the weather. I just want to fly,.....you know? Thanks much.
@@NightFlyyer Ouch! Sorry to hear about that Dave believe me I'm looking forward to flying this year also if the winds and temps got way better on my end lol.
Now I want to pick up some Cox engines
Right on! Thanks.
Very nice, thanks for the memories.🇺🇸👍
Your welcome and thank you as well.
Never gets old Dave, thanks 👍😁❤️
Thanks so much, Dave. Stay well.
I remember having a .49cc 50+ years ago that ran on ether. I made a UFO flier for it. Funnily enough, they have become popular again, i.e. the real UFO :)
That is a bigger engine for sure. I made many videos on our UFos. I call mine You FO's. Here are two of my favorites. This is my mini with a .049 ua-cam.com/video/DeWao5L6FLM/v-deo.html and this is my bigger Nitro version (I have electrics too) with a .32 heli engine. ua-cam.com/video/ujxDHp46knI/v-deo.html . Thanks much.
@@NightFlyyer: Yes Google says 0.49 cc is about 0.03 cubic inches so it was about 3 times bigger than your little one. I had the engine from a line controlled balsa wood and rice paper airplane. I didn't have any remote control then, so my UFO was not remote controlled but just flew vertically up in the air so it was important to not have too much fuel on it. So I used a small syringe as a tank, so I have some control over the fly time. Thanks for your reply, I was very surprised by the big UFOs, I hope you don't get into trouble for having leaked some "military secrets". Even though Denmark is also a NATO member, I've never heard of that project. I know of a plane I think was called the flapjack. Very interesting to see, thank you.
@@MitzaMaxwell Ritht on. You had a .049, not a .49 That is a big difference and why I was confused. A .49 is quite a bit bigger than these small Cox engines. Sounds like you had fun. Flapjacks were cool with twin motors. Thanks much.
That’s quite a lot of RPM’s!! I knew these engines did somewhere in the neighborhood of 21.000 RPM’s. It was very interesting 🧐 when I took one ☝️ apart. There was no magnet 🧲. The piston and connecting rod are very tiny, but these engines make A LOT of NOISE!! They’re approximately 1️⃣ horsepower, by what I have found out. I’m guessing that the plane does about 45 MPH, just by this engine. I never 👎 knew that the piston and connecting rod could be adjusted on these engines. Your friend, Jeff.
Very nice to see my friend :) I’m working on building a tee dee 020 from parts (can’t quite swing the cost of a full engine) I’m looking forward to getting back into the hobby. I collected these engines as a kid 2007-2012 but I’ve been out for over 10 years and have nothing in my collection thus far lol.
Yes, they have become quite pricey these days. Many parts can be found on www.coxengines.ca Thanks and good luck.
@@NightFlyyerthey most certainly have, I wish I still had my collection. I had nearly 40 engines all together, I’ve used coxengines before, they are a very great company. I lucked out on eBay and purchased a .020 piston, and the seller is throwing in a sky copter engine as well 😊 I’m working on creating a cad model based off a free flight model from 1947 that I hope to scale down and 3d print. What would you suggest for an all up weight for the model or an idea of wingspan? I’m thinking around the 24” mark and 2oz for the airframe
@@Miniaturerailwaymuseum That sounds like a good start. Nice and light. The engine will pull that great! Good luck and happy flying.
@@NightFlyyer thank you 🙏 I think that will be about right as well. I’m so excited to start flying again
I noticed that you angled the needle valve away from the prop to get more finger tip clearance, looks like a great technique. I have an .020 TeeDee that starts right up, but I've been too nervous to adjust it once it's running (been slicing my fingers on these props since I was a kid). Fun video, looking forward to trying what I learned.
LOL. Well, I still can nick my finger, but your right, this made it easier to adjust for sure. I recently ran my 020 and actually put it on an electric airplane. Maybe you saw that. Now go run yours and thanks much.
@@NightFlyyer I have also installed 020s (mostly PeeWees) on electric models, they work great on UMX planes. It's an easy way to get these engines into the air. As much as I enjoy running them on the bench, they are even more fun to fly! Take care, sir.
Me gusta mucho este motor yo tengo 4 unidades compradas en una subasta. Siempre quise tener ese motor
Gracias, Senor!
Thanks
Your Welcome!
I don't have any 010s, but I do have a couple 020s. Adorable little things!
The RPM isn't a big wow factor for me, but I also run glow cars, so to me a 27,500RPM engine isn't even particularly speedy. My sport use car engines rev to 32-33K under looad. Still, for how small that engine is, it's astonishing that it can hold together at those kinds of speeds!
Right, but remember this engine was first made in 1960, (63 years ago) not like the modern stuff today, so it still holds the title of the smallest production engine in the world. It worked well on planes and not designed for cars. 33 k on your cars under load!? Wow. What kind of nitro engine do you have that does that?
@@NightFlyyer That is NORMAL for RC cars. 33k under load is lazy for them and is the realm of mild mannered RTR sport engines optimized more for easy handling and reliability than raw performance. Kyosho KE-25, OS 18CV-RX(I own two of each), Associated AE 18(1x), and my OS 30VG which is designed to sling 20 pound monster trucks around like ragdolls also falls into that rev band. A race spec car engine will hit 40k under load!
I got tons of car videos on my channel. My Kyosho Scorpion XXL, my Mad Crusher GP both have KE-25s in them. The KE-25 is the OEM engine in the Mad Crusher and Kyosho still sells them to this day; if you wanna dabble with one and have the ~550 to spare pick up a Kyosho USA-1 GP. That truck is a blast to drive, the engine is a dreamboat, thing has a three speed auto trans in it, wheelies for days, sounds like an F1 car blasting across the yard....hehehe.
I started my adventures in hobby grade RC with cars, and with glow powered ones. Been doing that since 2003, when I was 13. Only got my 'wings' in 2019.
And ye, the little Cox td010 is an impressive li'l thing. They were pretty cheap back in the day, too. One of my holy grail engines alongside those OS wankels, but you covered the exact reason I don't own one in this video haha. Hell the only reason I got a couple of TD020s was I hit up the estate sale of a deceased aeroclub member and scored them for five bucks each.....
Beautiful ❤
Thanks kindly.
I forgot how small these were. Sneeze and you loose it small. :)
So true. I almost lost the first one in my Flying Shop Rag video. Maybe you saw that. Thanks. ua-cam.com/video/Q7MwFVHCRpY/v-deo.html
I can smell this video.
Right on. In my video on my other bigger ones, it set off the smoke alarm in my garage. LOL. Thanks much.
@@NightFlyyer ; Oh crap! At least you know the alarm is working! A good thing.
Smiley800, I was thinking the same thing. That fuel combustion is a very unique smell, seared into our olfactory nerves.
GREAT!
Thank you sir!
The engine I want was made by a guy named Ronald Valentine and it's the world's smallest diesel engine called the Nano Bee.
The last I heard they were over $500 bucks an engine.
Not sure what happened to that guy. Maybe he's still around making them?
If you lost any other cox engines in the fire.. I have a few doubles in my collection.. we could work something out..
I lost many engines for sure, and others have sent me these. I still do not have a .010. Do you have that one? Thanks so much.
@@NightFlyyer i do have an extra 20 but not a 10.. yet.. I’m going through my stuff. I have boxes of motors. I have 150 + in my cabinet but at least 2 boxes to look through yet
And the smell !!! 😋😋😋
Ah, yes...A truly unique smell for sure. Thanks Alan.
*I can't believe I threw over 100 of these in the trash in the 1970's rather than rebuild them. Live and learn and HOARD everything!!!!*
A hundred? Wow. My wife worked at Cox and even I never had 100 or even 10 of these .010's. What did you use them on?
@@NightFlyyer *In the 1960's and 70's my parents owned a family recreational center (Willy's Rec. Center) in Indiana. We had a Mini golf coarse, bowling, batting cages, bumper cars, arcade AND an RC Air Field where you could rent RC planes to fly. As you can imagine we lost money on the RC field end of the business while it did bring in lots of side business since RC rental was such a rarity.*
@@johnslugger That is a great story. Thanks. We used to fly ukies at Disneyland in the 60's, and I never knew there was another place to do that. Very cool.
Oil in the socket before resetting is a plus. The TD .010 rpm has been tested with small speed RC designs. I have hit 41K rpm unloaded with the stock prop! See test flight with a 2.56x4N prop down wind passes are shocking for such a small engine. ua-cam.com/video/3i4r2kDOBlQ/v-deo.html
I watched that and it really screams. How did you measure that engine ran 14,000 RPM over? Sounded the same on the ground as mine, but really great unloaded for sure. My wife worked at Cox when they were on West Warner in Santa Ana Cal. The chief engineer was a member of our club, and Joe Klause of Kustom Kraftmanship was a good friend. He made fine thread needle valves, chrome cranks, pressure backplates with nipples, etc. He would be impressed with a stock engine doing 41,000 RPM. Thanks and happy flying.
@@NightFlyyer Thank you and for sharing, regarding Joe over the years I have gathered up some of his offerings.😀 Per that last vid link best static peak hit 28,858 rpm. Prop used was a 2.56 x 4N it unloaded another 6,326 rpm to 35,184 rpm peak- data taken with a sound spectrum analyzer flown to apex rpm / speed in front of the camera. Best recorded static rpm data testing made 33,107 with an all carbon 3x3 prop. Here is the vid with the highest unloaded rpm mentioned previous post. Pass down wind with stock black prop 41,985 rpm / 50 mph prop pitch speed. The 3x1.25 is naturally low on speed for RC use given the pitch: ua-cam.com/video/IBf7OCBPTq4/v-deo.html
yeh ...buy new one.. collector's item class ...one nimrod posted $695.00...severe price gouge..OR collection value in the eyes of that collector ..never run it.(no flippin' fun)😉👍⏳🇬🇧🇨🇵🇸🇮🇩🇪🇸🇰🇺🇸🇦🇹🇺🇸🇺🇦😎☝️
