Cox 049 Babe Bee - Manual start up
Вставка
- Опубліковано 29 вер 2024
- Manual start up of a 049 Cox Babe Bee (0,8cc) model airplane glow engine. This model is also powering my Kyosho RC car. The sound, which is deafening, on the video is tampered by using a noise damper on the camera.
The engine gets its fuel through a fuel inlet in the fueltank, the air goes through a hole in the backplate. Fuel/air mixture intake to the crankcase is controlled via a reed valve.

Brings back so many memories. I had some control line cars with this little guy. I remember my dad out in the back yard trying to start one up for me. I must have been 5 or so. Hard to believe that was 45 years ago
It is running way too rich, close down the needle valve.
A delightful sound that evokes so many memories and the smells that go with them!
I recently finished an ASMR engine just for the sound and smell :)
My first engine when I started in radio control. At that time there were single channel radios and I had one.
Ahh yes. Me too
Yup… That’s exactly why I came here. The smells and the sounds, and the cold fuel spitting out onto your hands… something never to forget!

Oh man, brings back a lot of memories...but it was running so rich it was driving me insane! LOL It should be a steady scream :D
It was indeed running rich. I have to make a better video of this little engine one day!
It was already running long enough for the neighbours, lol!
@@2stroke4me haha. I know what you mean about neighbors, mine are gonna get the treatment today lol thanks for the video!
That brought back memories. I got my first Baby Bee for about $4 back in 1955, made by Thimble Drome back then. My second was mounted to a Thimble Drome plastic hydroplane boat, and ran as a pusher. The props we used were 6" diameter with a 3" pitch. Fuel was made by K&B. They had K&B 100 which we used, and K&B 1000 which was for larger (.18, .29 and .35) engines. Somewhere around the house I still have a Wen-Mac .049 engine. Thanks
Running rich turn that needle
I leaned it out when it was mounted into an rc car. This was only a demonstration.
I think the baby bee cylinder was more horsepower and had a nice cone shaped intake.
Wow, I am 59 yo, and this brought back MEMORIES! Thanks!
You're welcome :)
64 years old now
Yea, I'm 73 and this brought back memories.
Thank you! It brings back many fond memories of my brother and me building balsa wood airplanes in the Winter and then flying them in the Summer. :)
Runnin' rich, but lots of memories brought back for sure. Had fun explaining it to my daughter.
Haha, that's awesome :D
Left lots of crap on the plane.
Started with Ukies, & Cox .049's, 1959. 1976 first Radio, been flying radio ever since. "Ridge Runt" kit, 2 channels, ail & elv, yank and bank flying , with 049's and the Tee Dee engines, 5x4,to 6x4 props. A quart of fuel for a sunny afternoon of flying. Flights are 4-6 minutes for the last 30 seconds to a minute, climb up high. This is were it runs out of fuel and becomes a fun glider to do loops and rolls on the way down, it's a great way to practice "dead stick" landings, 'cause they all are.
Largest engine I ever had was an .035.
Gosh does that bring back memories. Sitting here watching the video I could recall the smell of the fuel and the caster oil. Sad to think that they don't make the baby bee any more. Pretty sure I have at least one laying around, in addition to larger .35 or .40 that my dad was going to an r/c model around but never got to it. Guess I'll have to drag them out to run for the grand kids... Thanks again.!
You're most welcome and thanks for watching!
Look at Brodak engineering for .049 engines and parts. Brodak specializes in control line model aircraft, and stock kits, engines, flying lines, handles, etc.
Brought back my childhood.
Nice start. But you did not lean it out to operate at proper mixture and RPM. You ran it WAY to rich and slow.
It was a test to see if it ran before i put it into an RC car. ua-cam.com/video/X4q7jKUZtzY/v-deo.html
Terrific video, really enjoyed it. I want to get a cox engine myself sometimes. But there is one thing I don't understand. Is there a throttle on these little engines? In almost all the videos online I see these engines run on one constant rpm. Thanks
Thanks for the compliment! These engines run at constant rpm until it runs out of fuel. However, throttle conversions are available too.
2stroke4me Okay great. Thanks for the quick reply
No problem mate!
Just a tip on these smaller engines. When the piston is at top dead center, a small gap is opened up below the piston allowing some the prime to go into the crankcase. Adding prime to this area and getting fuel to the crankcase really improves the starting characteristics of these small engines. Thanks Dave
Not all cox had the port induction.. but yes a prime always helps.
Love the 0.20’s too! I wish those days could last forever...
Loved it. What memories!
I'm glad you liked it! Thanks for watching!
Cox planes and cars were so fun! I had several, Myers Manx dune buggy, ATC 3 wheeler, and a Jerobe rc car were my favorites! =)
I always loved the buggy and i've never seen the Jerobee in real life. I don't think they were sold here, which is a shame. The McLaren was my personal favourite :)
@@2stroke4me The Jerobee was the McLaren Can am car it was very cool but I never had it running as a RC car. I had several control line planes most did not really fly lol! The ATC was fun!
@@mikesrcgarage Never seen the ATC in person too, but they sure look awesome!!
@@2stroke4me It was fun cause when it was running out of fuel it would run lean for maybe 10 seconds and really take off! Lol!
@@2stroke4me Just for fun for I've never seen it run as a RC, mine the radio was no good.ua-cam.com/video/HE5HzAbM3_U/v-deo.html
After I tore up my pt-19 cruiser control line plane. I kept the engine and run it in my hand cuz I was bored 😂😂😂. It was so damn loud.
Those could tape back together if dry of fuel ant tape both sides . But they just kept crumbling
I grew up on these things, beginning in the late 1960s. No other engine got so many people hooked on model airplanes, and I heard that total production was around ten million engines. Since a lot of folks seem to be discovering the joys of 1/2-A engines for the first time, the one factor that affects success more than anything is fuel quality. These engines run best with a nitromethane content of 20--25%, mainly to hold a needle-valve setting, but the most important factor is lubrication. You want 20% oil--and ideally this will be all castor, or at least a 50/50 blend of synthetic and castor oils. Using fuel containing only synthetic oil will lead to accelerated wear of the connecting-rod ball joint. You can feel the looseness here on engines that have not been run on proper fuel, and you'll be able to hear the ball joint rattle when the prop is flipped over by hand. Another factor affecting performance is cleanliness. Keep the engine clean and always use clean fuel. Have fun!
This engine got me into RC cars in the early 80's. It was powering a Kyosho car that i recently restored and has been running like a champ ever since again. These engines are virtually indestructable and the design is briliant!
*sing fuel containing only synthetic oil will lead to accelerated wear of the connecting-rod ball joint. You can feel the looseness here on engines that have not been run on proper fuel, and you'll be able to hear the ball joint rattle when the prop is flipped over by hand*
Is this really dangerous?
I´m running this engine on standard R/C fuel but with castor oil.
I have this "ball joint rattle" long before I let this engine run again after more than 20 years.
I got it as nameless nitro engine, looked for some information about it, and now I got this fuel and the engine runs again.
But i broke my propeller last week... So I have to buy a new one...
The Cox engines are recommended to be used with fuel containing castor oil.So you shouldn't have a problem there.
Since a very long time, i use HPI fuel containing Klotz oil and I used to add a small amount of castor oil to the fuel but the Cox engine on my rc car still runs fine without the extra castor oil and very clean (no carbon build up on the piston).
Parts can be found at "Cox International" on e-bay.
2stroke4me Okay thank you for your feedback.
I already know the "Cox International" Website and of course the ebay shop.
I already bought some new gaskets on Ex Model Engines, they´re also selling some parts like gaskets, glow heads, needles and so on.
I had one of these when I was a kid. Nobody ever had the right spanners for the head and cylinder, so they all looked like that,..gnarled up from using pliers instead!
LOL, same here. I used to have 2 spanners, lost them both.
@@2stroke4me I don't think I ever had them to start with, as most of my first engines were swaps,.. engine for a crappy air rifle, that sort of thing!
That wonderful sound....and that amazing exhaust smell. I'm 8 years old again.
😎👍
You should have leaned it out some more to get max RPM. Thanks for the memories. I had many Cox .049 engines and airplanes as a child. Greetings from sunny Jamaica.
Looking back at it, i should have (it was very cold outside). I have one in an RC car and it runs fantastic!
Thanks for watching and greetings fom the rainy Netherlands!
Is this as simple as it gets, and runs on compression alone?
The fuel (methanol + nitromethane) reacts with the platinum filament from the glow plug under pressure causing the fuel to combust..
2stroke4me superbly simple. I note there’s quite a lot of fuel loss (as opposed to exhaust) and I remember this as being a problem on paintwork and tissue paper not properly doped. (My friend was/is an avid RC flyer since School Days (late 60s) but he’s now in America).
Presumably this has now been improved upon. It’s a hobby I’d like to get into but being in my 60s now, and having many other hobbies, I don’t think I have much time left!! My hobbies include Model Railways to a greater extent.
Thanks for sharing the demonstration. It has set my mind wandering on happier times of our childhood. Best wishes.
Bobby D Although the engine was quite rich, they always spit out some fuel and oil. Modern engines, especially the bigger ones, are more efficient and come with an exhaust. I don't fly, but most of my cars have engines, they all stay clean (except for where the exhaust exits the bodyshell).
If you really want to get into flying, and you can afford it, don't let age stop you. Life's short, take the most out of it!
@Andrew Trumbo 2 can'ts = can
I just ordered one and am in the process of learning how to use these. What do you use to light the glow plug and where can I get one? Also what propellers work for this?
I use a 1,5V battery, leads and a couple of (Olvis) plugs for the glow plug. As long as it activates the glow plug, the engine start up. I have no idea about what props you can use since i'm not into flying. This little engine is used in an RC car.
They're very easy engines, and as long as you don't let it run too lean, they last a very long time. Have fun with it :D
Used a 6"×3" on my RC models and CL, good all round size. Have fun!
thanks for the break down on the engine. i never knew they had an air intake. i thought it grabbed air from the cylinder and piston area.
You know what run times you can expect with the 5cc tank? I want to eventually build a plane kit and do a Cox engine powered free flight setup so knowing exact run times is important.
I think the run time is approximately 2 minutes, but i never timed it. This engine now sits in a Kyosho RC ca and has a large external fuel tank.
@@2stroke4me Thanks for the info, also very cool upgrade to a classic.
@@themadscientest You're welcome and thanks for watching!
@@2stroke4me Love to see the configuration of this engine.
@@themadscientest You can see it in action here: ua-cam.com/video/X4q7jKUZtzY/v-deo.html

Смесь богатая. В конце, когда топливо заканчивается, смесь нормализуется и он работает нормально. Из под головки сифонит (пропускает).
Коленчатый вал так и должен продольно перемещаться?
Lean it out man!, it's running way too rich, it picks up and starts to sing just as it runs out of fuel but it should be singing like that all of the time.
I leaned it out when it was mounted into an rc car. This was only a demonstration.
@@2stroke4me Fair enough!
Had a red 4 w2heel race car with a pusher .049 on the back. We called it a prop-rod. Fun days.
it starts very soon. i want to buy a cox 049 red arrow
I read somewhere that cox motors need more nitro because of the small surface area of the head
Depends on what they mean with more nitro. They run very nice with 16%, which is a lot for these engines. I tried 25% once but that's not something these engines are designed for. It's even too much for my .12 and .15 engines but my .21 (and above) engines run fine with 25% (except for my classic .21 engines)..
As it runs out of fuel, and leans out, it really picks up rpm!! 👍👍👍
👍👍 :)
Yes, because he dont know how to tune the needle and tighten the glow plug
I didn't know that 42 watts could slice and dice my finger so well!
First you need to tune it up a little. Running way to rich. Second this wasn't the smallest engines Cox built. There was the .020 and the .010. The .020 ran like the .049, but the .010 was a pain to start and keep running.
I didn't bother tuning it right since it wasn't propelling anything.
And where did i state that this was the smallest Cox engine?
It seems like it's running backwards, the excess fuel is just dripping and even being sucked up towards the propeller.
Estoy necesitando una de ésas. Donde la puedo conseguir en Colombia?
Head gasket needs replacing or the head needs to be torque down tighter
Brings back great memories I've owned several of them and lots of fun lots of hurt fingers especially trying to start in cold weather, but nonetheless great memories. Still very much into RC planes at 78 years old. Thank you for the Post.
Yes I remember hurt fingers I one time stuck my finger at the edge of the Propeller and it hurt. also if it kicked back when starting.
I remember the little guy smokn up the garage.... the good old smell
I have one red
I can LITERALLY smell this video………..
i can almost smell it
It's a great smell :)
The one I have has what looks like a Brass back plate!
As far as i know, a brass back plate indicates that it's much older than mine!
Golden bee ?
Thanks a lot . it brought back very fond memories of my childhood.my neighbour had it and he had mounted this on a BALSA wood SPITFIRE!!!!!!!!!!! Thanks so much
You're welcome, and thank you for watching!
do you happen to know how long the fuel will last the engine?
It's like a minute or so if i remember well. This engine is used in an RC car, which has an external fueltank.
What voltage du you use on the glowplug ? also do you use ordinary RC fuel ?
I used a single AA battery and HPI 20% car fuel.
1½ volts
Very sweet memories from my golden past.
after you remove battery how can it run without any volts i mean where did it get power for explosion
The methanol in the fuel reacts with the iridium on the glowplug's filament. Sometimes those filaments are made of platinum, which causes the same reaction (catalytic decomposition of methanol with a platinum catalyst).
The nitromethane helps to accelerate the combustion.
It's like a diesel, it has a glow plug.
The glow plug filament is heated red hot by the electric current. The ignition of the fuel keeps the filament glowing hot enough to ignite the compressed fuel mix. Glow engines run pretty hot.
what propeller do you recommend for a 049?
I have no idea, i don't fly. This engine is used in a car.
6×3
5 or 6 inch diameter . Pitch is like gears . Higher pitch higher speed but too much pitch it stalls when sitting still , will need a push to get moving.
Less pitch plenty of piwer going slow but no fast top speed .
6x4?
I have a Black Widow version of this, still running great 😎
They're indestructable little engines :D
1:27 yur glowplugs leaking gases and compression. U dont have a copper seal ring under the plug or its loose.
1:29
I’d this engine the engine top speed nitro World and then It I was a little rc nitro nitro car
i have no idea what youre trying to say
works good if somone has there stereo to loud
It would be nice if viewer's questions were answered.
As far as i know, every question gets an answer.
Andrew Trumbo I miss the foundation of your accusation. (sorry for the late response, your comment didn't show up in my inbox)
I recently inherited one of these and I'm interested in setting up something like a piper cub. What size plane is this ideal for?
I have no idea, since i use this engine in an RC car. I have no experience with RC planes, sorry.
We had Cox planes when I was a kid, DakGuy. They were pretty small...12" to 18" wingspans were about as much as a .049 would lift. Something like a 5cc engine would be more comfortable to fly with.
Hahaaa. . I remember so well , 40 yrs ago and my cylinderhead was leaking like that too ! ! !
They are always a little greasy after use :-)
Es la bujía para ese motor
Tie a rag to it and set it free!
Are these motors still being made?
I have no idea, but i think they're still being sold in Canada.
with how much power do you glow the glow plug?
I used a 1,5V AA battery. It doesn't need much to fire up the engine.
I have one more 30 years!!! Equipava um P-40 (Tiger Flight).
Cool! They are great little engines!
I have a COX p40 engine saved too . FROM THE 50'S i think . Beige plastic one it was .
+The8sidedcircle LOL! That must have hurt! That's why i stuck it in a car, much safer :)
Hi, this is quite a noob question since I am new to CI engines for rc butplease bear with me...
Can you "feed" the fuel tank while running? Also, I read that the tank must be airtight. How does it overcome the vacuum that is formed when the fuel is used?
Thanks a lot everybody!
Hello. Yes, you can feed the fuel tank while the engine is running. And on these kind of engines (Cox engines), the fuel tank is on the back of the engine and is always open. Otherwise it would indeed create a vacuum.
It's a bit different with engines that have a carburetor. The fuel tank is connected with the exhaust via a fuel tube, so that the pressure from the exhaust pressurises the fuel tank in order to feed the carburetor. There the fuel system must be airtight, otherwise the engine is barely tunable and runs inconsistent.
The Cox engine's intake is regulated with a reed valve. The vacuum created by the piston (going upwards) draws in the fuel/air mixture, so the fuel tank doesn't need to be pressurised.
The carburetor operated engines draw their fuel through a hollow crankshaft. The vacuum from the piston is not enough to draw in the fuel/air mixture. That's why a pressurised system is needed, like here: ua-cam.com/video/HHSzUomCWRc/v-deo.html
On this engine, it's the seal between the engine crankcase and the tank which must be airtight. For most engines, whether the tank is attached (as here) or separate, the tank needs a vent to prevent vacuum. Some engine-tank setups have the tank pressurized instead of vented.
I used to position a second fuel tank behind and slightly above the Cox engine. This extra tank fed into one of the Cox engine filler pipes and the other filler pipe was one was closed
off. I could get long flight times with this setup. I'd draw you a diagram and slap it in here IF I COULD.
There is a tube to fill the built in aluminum tank with a skinny hose from the fuel can . Ans a vent hole for over flow . Keep it right side up during flight or fuel will drip out .
It uses methynol alcohol and castir oil mix .
After all this time, thanks to all of you. I was worried back then about the risk of getting a messy fire because I had been told so with rc cars.
Car pilots complained about getting the engine running, and only having some minutes remaining after much fuel wasted on the warm-up
doubt what is the oil for the 049 engine?
Castor oil and methanol alcohol mix for .049 cox model engine .
My dad put everclear or moonshine and castor oil when once when the older neighbor kids were having trouble starting their cox stuka .
They were very enthusiastic with the results
Schöne Erinnerung, als ich 12 Jahre alt war war das mein erster Verbrennungsmotor für Modellflugzeuge. :-)
With wich voltage do you start the engine ?
I use a AA battery (1,5V).
SpAsTiKzOcKeR 77 we started them with 6 volt lantern batteries to fly them.
1 1/2 to 2 volts is the usual. Anything over that, including the mentioned 6-volt lantern battery, has a good chance of destroying the glow plug filament.
Et dire que ça se vendait en masse ces petits trucs !!! LOL J'en ai eu pas moins de 5 !! Dont 1 RC !!!!....
i killed my propeller... now i can´t start up my engine :(
I also have no idea what I should do with it...
MultiWirth Buy a new propeller.
❤❤❤❤❤❤❤❤❤❤❤❤❤
What percentage nitro fuel do you use? Thank you
I used 20% with a bit of extra oil added.
were is the muffler?
The muffler is optional, mostly used for populated areas.
In this video, it's running with a muffler: ua-cam.com/video/BcLQN3mQQQw/v-deo.html
Never used no mufflers on any of our engines. I don't think that hey were made yet in the early 60's.
I can smell this video
Thanks mate. i Love to play around with them :)
Sssooo.... (newby here) if I wanted to just have a running engine, is all i need the engine itself and the fuel? What about the electricity for the glow plug? Will it run on pure kerosene or ether? I kinda live far away from anywhere. ;D
Hi. These are glow engines and run on a nitro/methanol/castor oil fuel mixture. To start up the engine, the filament inside the cilinder head needs to be ignited first.
There are small model Diesel engines too. They run on Diesel fuel and need no ignition from a battery.
Model diesel engines run on a fuel very different from truck/auto diesels. You can't get it at a gas station. Kerosene and (usually) ether are part of the mix, and they are two-strokes so they have to have oil for lubrication. Davis Diesel Development sells ready-to-go fuel, or you can find recipes on the internet. If you decide to mix your own, pay close attention to how it is done.
whats the nitro % for this engine??
+Luke Shaw 25% 30%
that high ea?
It appears that the plug/head gasket is either bad or missing. Take a look at the blow-by at the bottom of the plug as the engine runs.
I forgot to tighten the head properly (as explained at 1:31).
It said that on screen 🧐
I fired up my .049s last summer for giggles... Man these little boogers are absolutely *deafening!!!* Even with the impossibility of buying inexpensive lipo batteries in Canada, I'm a fan of electrics. The I.C. engines are cool little machines, and the 4-strokes are less of an earsore, but in my country someone is liable to call the cops on you for disturbing the peace :)
Great little mill though, thanks for the U/L
Haha, yeah, they're noisy alright. Same thing here about the noise regulations, but fortunately my neighbors don't complain about it. Indeed, my fourstroke buggy is less painfull but produces more decibels although my Cox .49 powered Kyosho is as silent as a whisper.
Thanks for watching and i'm glad you liked it :)
@@2stroke4meHi mate what fuel do u use in it and what battery are the leads connected too I found one of these in a friend's garage here in new Zealand and really wanna run it
@@utubetattoodude I used HPI 20% fuel and a AA battery for the glowplug.
Hiya I bought a Baja car with this engine I'm and wondered what fuel I need? thanks
+Wesley morgan brain Hello, i use HPI fuel containing 20% nitro. I used to add a little bit of extra castor to it but it runs fine without it. The HPI fuel already contains the correct amount of oil.
+2stroke4me thanks very much I'll get some on order I bought it off eBay the other day because it took my interest, I got it all fixed up and ready to run but wasted sore what fuel so I youtubed it and found your vid very helpful
Cheers again
Wes
+Wesley morgan brain You're welcome, i'm always open for questions and suggestions!
Have fun with your car mate!
Whats the maximum voltage to put through run of the glow plugs or what set up do you recommend electricity wise as i keep going these glow plugs every to runs or so which cant be right what sort of current is best as well. Thanks
alex monk I use a 1.2 Volt AA battery.
ok cheers will try that next time.
In the way back days, 1 1/2 volt dry cells was standard. Some people figured out how to tap a wet cell battery to get two volts using just one cell. Much over that and there's a good chance of destroying the glow plug filament.
Man that's a lot of play in the prop shaft.
Yeah, but it still runs great!
how much nitro are you using on your fuel for the cox? is 10% enough?
i Use HPI 20% model engine fuel because it runs more stable that way. And i add a tiny amount of castor oil to the fuel.
10% is pretty low for good power. 20-25% usually better. Any higher in this engine is wasted.
Cool man nice sound
Thanks bro.
got two of theese, one is late 40s early 50s
Wow, they are indestructable, aren't they!
+2stroke4me I really believe that
Same one of them kinda works the other on wont move at all
Looks as though it was running backwards.
+GrizzlyRecoveryZone1 Well spotted! They sometimes do that. This is prevented with the snap starter spring.
Babe Bees are notorious for starting backward. Sometimes takes 4-5 tries. Spring starter helps a lot. Of course, If you have a pusher installation, you want reverse running. Just put the prop on backwards.
holy smokes, thats the smallest engine i have ever seen
And this isn't even the smallest one. Search for Xox .020 Pee Wee.
And teedee .010 Can't recall if they also had a bee .010 since I was there and ran them so too old to remember details :)
Rick - Cox made a .10TeeDee and these were great for light aircraft. No .10PeeWee's were made.
@@2stroke4me Cox also made a TeeDee .020. No PeeWee made in .010.
this is a great little video here...I just got a dune buggy with a Cox moter on it...and then just a spare motor as well...think I will try starting it soon...any word for the wise ?
+Ramsay R/C Thanks :) It's like any other engine. Make sure you've primed it before starting, inspect the glowplug and don't use more than 1.5 Volt for the glowplug driver.
2stroke4me sweet thanks...you say you are running 20% nitro in that ?
+Ramsay R/C Yes indeed, and without any problems so far.
2stroke4me sweet thank you very much for the info 👍
+Ramsay R/C No problem mate!
what voltage is needed to start it?
+Jose Torres It's recomended not to go over 1,5 Volt.
thank you
Prop, fuel used please
The prop says "5D 3P" and "Thimble Drome" on it. I think i used 16% HPI fuel for it back then.
How does it get fuel into the cylinder
It gets its fuel through a very small reed valve, just like a conventional 2 stroke engine.
The reed valve admits fuel into the crankcase. The down-stroke of the piston pushes the air/fuel mix from the case into the cylinder through a bypass port in the cylinder.
Andrew, assuming you meant to say, "He's incorrect.", in what way is either response incorrect?
Where is the muffler?
The annotations don't work anymore, i made a link which shows up in the upper right corner after 15 seconds.
My appologies.
No muffler. Straight out of exhaust ports.
What fuel does this use?
+JBpiification I use HPI 20% model engine fuel and it runs very stable with it. I used to add a small amount of castor oil to the fuel but the Cox engine on my rc car still runs fine without it.
Ok thanks!
+2stroke4me I have this exact motor, I think the glow plug isn't working, do you know we're I can get a new one. also can I make my own fuel out of isopropyl alcohal and oil?
Hello. Parts can be found at "Cox International" based in Canada and on E-Bay (where Cox International also seels parts).
I don't think it's a good idea to use isopropyl alcohol, i think it's going to dissolve oil instead of mixing with it.
You should hear one of these in real life, lol. i Had a thick piece of foam covering the microphone. It's deaffening but not an ugly sound.
MUITO LEGAL, BRASIL OK.
I like 👍 it!! 1:38!! Your friend, Jeff.
