I had a Cox PT-109 plastic control liner back in the early 80's which had a 0.049 in it. That sound took me back but I don't miss it, I spent more time mucking around with the engine and getting covered in oil than actually flying.
I have found great satisfaction in dealing with Cox International. They are the most helpful and fast in supplying engines, parts and information. I highly recommend them.
I had a Cox control line plane in 1968 when I was a kid. I am sure my neighbors hated that plane due to the noise. My friends all had the same plane, the Cox blue and yellow trainer and we flew the planes in the street. I think this motor had a spring start and I remember cutting up my fingers a bit trying to get this darn motor to start on a cool winters day.
Yes I can buy one of these now. And the best part is its a Canadian website so the shipping coasts are reasonable, im going to splurge and put about a hundred in to a customized external gas tank one. Great video thanks
Wow, long time a go. I found an 049 engine in a junk drawer and expect that with fuel it to would start. For me it would be in the 1960's. free flights in the 70's.
Hi Bruce, I thought you might enjoy the video response I posted on throttling the Babe-Bee reed valve engine similar to what you're using on this project. I haven't seen any other videos that use this secondary needle concept. I like it because it's simple, straight forward, you can MAKE YOUR OWN... and it works. See my vid's "extended" text for more details. Happy modelling mate!
Entertaining and interesting video, as allways. Is there any way to control the throttle, when the plane is in the air? Or does it run on the same speed until the tank is empty?
Very nice video I love those engines, thanx for uploading!!! I have a couple of those but they say you should run those with at least 15% nitro to 25% nitro with methanol and castor oil only, not sinthetic oil to get the best performance of those little powerful jewels.
where do you get the clips and the battery box from also what volt batterys and persentage nitro are you using please comment back i have been wanting to know for years
Was Googling Cox .049, to see if they were around anymore. 11th Grade, Vegas,70's, Votech Automechanics, had access to a lathe, messed with dirt bike engines, understood the Principles, Sanded the head at first to increase Compression Ratio. Then put the head on the Lathe, turned it down till one cooling fin came off, but now head would not contact the copper gasket, had to put cylinder on the lathe to remove 1 cooling fin, it now seated, then would use Airplane Engines, not Dunebuggy or car, The Airplane Engine has 2 Transfer Ports, the Cars had 1 transfer port are inside the cylinder, you can see it dissembled, it is a channel that runs up the inside, when piston goes down, it pushes fuel up, piston passes too of transfer port, compression begins. These Engines had so much compression you would have no problem raising and widening the Transfer Ports, They Screamed louder, maybe even higher Pitch(higher (RPM)than when you had in Fast Forward, only difference, You would see the Flames shooting out the sides. When out of fuel, They would randomly fire, stop by throwing a Rag on it and Refuel. Never got to put on a Plane. Just a Mount I put in a Vice. Was not into RC yet, but if on strings, you would get dizzy. Have to do more searching on these and availability. With Company's going under, I never know who is still around. The Pull Starter Clutch on their cars had 2 rollers,y 1100 Magna was very similar, but had 3, Allows Starter to rotate engine, freewheel when running. Miss Em
hello what fuel are you running because these engines need castor oil anything with less that 20% castor oil you risk damaging it they wont run well with synthetic oil
never knew there was much of a "break in" for a cox since the piston can spin in the cylinder..i just run them a little fat for a flight or two then lean them out after about the 3rd flight..ive run the piss out of these things since i was a little kid and every one ive ever had still runs perfect with great compression.
I had a Cox Baby Bee clamped in a vice in my basement. It started fine, but vibrated loose from the vice.The darn thing was jumping all over the place because the propeller was hitting the floor. It eventually stopped. A good lesson learned...
I have a cox sure start 0.049 which I didn't know how to use, so it was lying for 5 yrs and got jammed. Now I have a trainer with a os 46 ax so I also got out the cox and cleaned it out. I am using 0%nitromethane that is 20% oil and 80% methanol. It gives me only 2 minutes on a 10 ml tank. Is it bcoz of the fuel, or does it only run for such little time and drain out a full 10cc? Please help.
Allways run the Cox out off fuel,if you leave any in it the alcohol evaporates and the flutter valve gums up,which means a strip down and wash with meths,(Same go,s for Iron Horse lawnmower engines) I consider %10 Nitro minimum,and Cox grey props work best,and keep fuel stoppered to prevent evaporation, and make sure the glow plug has a healthy glow, Do these things and you have a sweet little engine, enjoy
No! The genius of the glow plug, once the engine has started, is that the combustion phase of the 2-stroke cycle, heats up the glow plug filament coil, which retains enough of that heat to ignite the fuel during the next cycle's cumbustion phase, which re-heats the glow plug filament coil, etc. Pretty cool liitle system, huh? It was invented by Ray Arden in 1947.

Lovely childhood memories with these back in the 70's, the COX PT19, the staple must have to the lads.
Wow, just got a very good flashback to my teens!
Wow! I haven't had a .049 in years . . in all honesty that was very therapeutic to my sole :) Big Thumbs up for this video . . I could almost smell it

Boy, that sound brings back memories.

Yes, a big flash back for me!!!! Love the sound it makes
Bernie from Cox International is a hell of a nice guy.
Wow I remember my younger days... Flew a U-control airplane using this engine.
Wow, long time a go. I found an 049 engine in a junk drawer and expect that with fuel it to would start. For me it would be in the 1960's. free flights in the 70's.
I remember these little guys on the Cox EZ-BEE!! By the time you get it tuned, and launch the plane, the tank is almost empty!! LOL!
I like how it's able to vibrate the batteries sitting on that heavy bench.
Remind us to the good old days
Love it. Fond memories!
sweet ! I am really thinking about building myself a Cox plane. thanks

Aye its rcmodelreviews guy!
where do you get the clips and the battery box from
also what volt batterys and persentage nitro are you using
please comment back i have been wanting to know for years
Another thing, how long do they last before you have to rebuild or retire the engines?

damn that sounds like music to my ears! im thinking of buying one of these to just rebuild and get running
never knew there was much of a "break in" for a cox since the piston can spin in the cylinder..i just run them a little fat for a flight or two then lean them out after about the 3rd flight..ive run the piss out of these things since i was a little kid and every one ive ever had still runs perfect with great compression.
how big is the fuel tank? and what is the run time for a little nitro like that?
I had a Cox Baby Bee clamped in a vice in my basement. It started fine, but vibrated loose from the vice.The darn thing was jumping all over the place because the propeller was hitting the floor. It eventually stopped. A good lesson learned...
+metalmoto LMAO I did the same thing only it was my 46FXi, mine didn't fall on the floor but it sure cleared everything of the work bench.

Please help.
Does it have a throttle or is it a set rpm? Also what % would you run it on?
I’m gonna try making a 1/24th scale nascar die cast RC with this engine
This little baby deserves to be in a Pitts Python! Do it mate! Do the Python! >.
Allways run the Cox out off fuel,if you leave any in it the alcohol evaporates and the flutter valve gums up,which means a strip down and wash with meths,(Same go,s for Iron Horse lawnmower engines) I consider %10 Nitro minimum,and Cox grey props work best,and keep fuel stoppered to prevent evaporation, and make sure the glow plug has a healthy glow, Do these things and you have a sweet little engine, enjoy
@xjet also what ith the thrust/output of that little nitro?
bruce, bruce, bruce, tsk, tsk, tsk, never thought i'd see the day you sell out to the "nitro" crowd. these are GLOW ENGINES, DAMMIT!
what model are you putting it in?
I think he meant when you where messing with the small nob. idk, I don't mess with these things lol
how much will these cost
@xjet oops sorry i just feel its my duty to make sure all cox engines are safe ;]
pls how much nitro are you using? Thanks
will you be able to run an engine on regular gas?
No!! 😱
3 turns for the needle valve
Do you try to take off the table ?
Just to start the engine, after that the plug in the head will keep its self (hot)
can you run diesel is thes
Does a battery have to be attached
No! The genius of the glow plug, once the engine has started, is that the combustion phase of the 2-stroke cycle, heats up the glow plug filament coil, which retains enough of that heat to ignite the fuel during the next cycle's cumbustion phase, which re-heats the glow plug filament coil, etc. Pretty cool liitle system, huh? It was invented by Ray Arden in 1947.
A battery *does* need to be attached to the engine, but that's only for starting it. Once the engine is running smoothly, it is disconnected.
Too bad this little thingy has been deemed illegal at our venue. People find the noise annoying. Don't know why actually.
hmmmmm I have a small electric starter that I believe was intended for teh small Cox glow engines....Rgds...Laurie
my first plane cox .49 control line
Me too
that it is the price of this engine
there is no throttle on most cox engines including this one
Yup
Dude!! I was afraid that this shit was going to explode and catch your arm-hair on fire!!
@xjet so true lol
@rolgarcia1 no
