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  Grin

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

Try this for throttle conversion.

@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.

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.
