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

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