Fireteam can almost outrun the disc, so its rather worthless to use if the fireteam is running away from you :/
Give it a wee bit more speed when holding the button for speed boost.
And imho, the “reach limit” on it should be decided on the times you turn and direct it.
It should go in a straight line much further, but go shorter if you constantly kept turning it and adjusting its path. Just my thoughts
