How do I make "long tail" particle on moving object?

Hi,

Actually I dont know the exact word to describe, so I call it "long tail" :)

It is like rocket fire effect, flying fairy sparkling, or the "whooossh" behind fast moving object

There is super awesome game "The Next Penelope" made wih Construct that describe more or less.

The "tail" effect behind the car when moving.

I tried use particle object, but It doesnt look close, especially the cone shape become bigger at the end

Anyone has idea how to achive this ?

For the trail, use a circle that has sine behaviour to shrink it and fade behaviour to make it disappear.

C2 Example: dropbox.com/s/0vfs88ovgm4gujy/Fade%20Trail.capx

Use arrow keys to move the blue circle (has car behaviour)

You can easily do this with particles:
