I was always impressed with the throttle ring on the Cox .049 because it seemed to always work and the engine didnt die. Also it gets really quiet! I remember a guy with a Q-Tee in the mid 1980s that had a plastic back top needle Shure Start type motor with a sleeve and he would throttle back and fly by five feet off the ground at about walking speed and it was soooo quiet! I seem to remember that it was quite fuel efficient. Thrifty!

Hola , disculpa la pregunta , no le quita vueltas ese escape. ??

So, this is an actual carburetor and ALSO an exhaust ring working in conjunction?

Exelente video Good Running Tee Dee…..❤

I would like to see some detailed photos of what you did, operates perfect but may i ask why you didn't used a throttle ring which has less parts?

This clever idea works perfectly! In 1979 I made a hovercraft from a slab of expanded polystyrene, or "tergopol". I wrongly thought it needed a more powerful lift motor than propulsion unit. I used my Cox .049 for the former and my .020 as the latter. It was a terrific struggle to get both motors running at once but, once I managed it, I topped up both tanks, placed the thing on the smooth flat playground of my school, and released it. It began to spin violently, took off, and flew away! I was heartbroken to lose the engines.

Nice, I had a combo like this as well, same plane and motor, back around late '90's. nice

Nice. What size prop and spinner did you put on it. Mine is getting a DLE 35cc Rear Exhaust on it.

Can i use only diesel eter and oil?

Hola Sr. Mauricio! Gracias por compartir sus conocimientos. Yo, ansioso de verlo volar con sus nuevas correcciones. Saludos!

Excelente Mauri!!! gracias por compartir esta informacion y exito en el proximo vuelo de prueba.👍

cant wait to see this baby fly!

Gran avión solo mejora el motor quedará de maravilla.

What an amazing job you did with this little jewel my friend, keep up the good work!!!

Replace engine w/ dead weight = engine weight and glide test to assure it's the engine.. I've had a zillion of the .049s and never had them pull left. also check lateral balance along with the cg balance. Carpenter scale in a vise works fine.

La construcción del avión es perfecta pero el motor no tenía las suficientes revoluciones ,era evidente antes del lanzamiento ,parece que el silenciador lo asfixia y no llega al máximo de rpm . Personalmente los 049 pienso que están fuera de contexto al día de hoy ,aunque tenemos cantidad de materiales buenísimos para construir y equipos de radios excelentes El 049 no se luce ,no tiene potencia para disfrutar un buen vuelo de un piloto experimentado ...en cambio el 09 si es una máquina digna para un vuelo a cuchillo o un invertido a raz del suelo

It idles down lower with the muffler... than they do without it

21k is pretty good for the .020 Pee Wee, and a 7k idle is even better. Especially for a home brewed throttle solution. I can get a stable idle to about 5.5k with a factory throttle ring, but never a 21k top speed with one. 👍

Buen trabajo de scratch build, Sr. Mauricio! 💪🏽

Well done. Liking the color scheme!!

Good work Mauricio. Thanks for video.

Muchas felicitaciones Sr. Mauricio! Alta capacidad de ingeniosa modificación y utilización de recursos reciclables.

What the musik in the begin of move?

Hermosa la Citabria Mauri, te felicito, seguramente va a volar de maravilla 👌😊

Mu bueno!!

Excelente trabajo!

Nice 🙂👍

Hola, le consulto: en que parte del cilindro va colocado el aro de aceleración, a la altura de las lumbreras de escape? Gracias!

I remember purchasing my first cox .049 engine when l lived in the Bronx in 1956. I was 11 years old and paid $3.95 for it. What a thrill it was! It was bubble packed in a blue container and purchased the cox fuel with it. With my father's help ran it in my bedroom and mounted it to a board clamped in a vice attached to a chair. Boy was it loud! Back then most flew U control planes because we couldn't afford RC with tube radios.

自分も、COX02PeeWeeのスロットルと、マフラ-付きの自動車模型用シャシ-を今でも、持っていますよ😮駆動方式はウオ-ムギヤとス-パ-ギヤとディスククラッチ付きです。自分のも、マフラ-付きなので室内走行出来ました😅

Fantastic job on the flight your buddy did a wonderful job 3d printing that whole front for you looks as good as new👍😎👍

Show,muito legal esses Cox Obrigado por postar videos assim. Abraço. 👍🤣🇧🇷🇧🇷🇧🇷

Sería el poder del Cox Babe Bee clásico (no SPI) bastante para este modelo? Tengo un avión con el Babe Bee/Cox RC Cruiser 049, peso 460 g, no hay demás poder, pero con 360 g no so... ¿ Has volado con el Babe Bee normal?

Nice job on the flying cool song choice too👍😎👍

Bravo👋👋👋on a job well done on getting a throttle set up on this engine to work just as well as 2 stroke 46 size engine amazing once again😁

Wow!! This has to be the very first time I ever seen a Cox PT-19 that didn't have that yellow and blue color scheme on it I actually had that one back in the late 80's sadly it crashed on the first flight☹️ But I really love this very unique color scheme you have on yours looking forward to seeing fly this one soon the engine is running a like dream BTW👍😎👍

Felicitaciones, hermoso. Que ocupes la radio original Sanwa-Cox de 2 canales le da un gran extra.

Un aplauso señor, usted si que es un aeromodelista!!! y de pura cepa. ; )

Buen día....por favor regalame el dato

Nice job! Cox also made a muffler, the QT engine, but it cut performance quite a bit.

loved your engine in wrong direction fix!!! gonna try it now but no worries I have had my fingers in many of 5 x 3iees and still have not learned, glad ur flight went well

Estava no aguardo desse momento. Belo voo. Abraço. 👍🇧🇷🇧🇷🇧🇷

Perfeito seu trabalho. 🇧🇷🇧🇷🇧🇷👍

buenisimoooo tengo varios 0.49 y ya me diste buenas ideas 😁🙃😉

You're welcome my good friend!!!

great!

HOOoow this is hardcore POWERRRRRRRRRRRrrrrrrrrrrrrrrrrrr 😵

HOOow nice run! When I was young I also had a COX with a line control aircraft, so of course I continued with that hobby... you did great sir!... good luck with...

Fantástico. Que bonito. Fue mi segundo avión U Control en el año 82. Pero el primero que volé bien. Es de los que mejor vuelan de toda la serie. Inolvidables recuerdos. Un fuerte abrazo.
