i have a cox surestart 049 engine.... i am new to engine driven airplanesis it possible to control the speed of the engine without throttle conversion...or is there a throttle valve near me ? please help

no these are control line or free-flight engines, if you need speed control throttle mod is the way!

here are videos of my cox surestart .049



never run your cox inside, needs good ventilation

have you broken in your motor ? why don't you try making the throttle body 

@rajji You will always fly fast and once you are dead stick glide and land safely.  

Try this for throttle conversion.

Damn 15$ US its a rip off   i'm making few for myself 

Is there a shipment to India on it :-O

@sundaram sir,
Sure we/anyone can built a carb with a throttle, but
Can't help wondering when we'll attain the standard of workmanship shown by Leroy Cox /Bill Atwood over 50 years ago.
There's a guy i don't know and haven't met, called pline on this forum...
(The railway wallah)

@pline
Can't think of anyone else who could actually do stuff like this...

Iyer Sir, I would agree with you on that. Hats of to the creativity of the man, that engine design will last a century if not more.

Can any one send me the inner design of throttle valve for Cox 049 please?

Hi rajji,
Is your engine in a running condition?
Also, what fuel do you plan on using?

An exhaust restrictor may be easier to make.

I am using a Nitro fuel mixed with 20% Castor oil

Where do you fly in manipal?
