Just to double check. I need a set of Quad IV intimadators NOT Quad IV-X. Right?

I'm running the Quad IV, I think they're the Intimidators, been awhile since I bought them. I just refer to them as Quad IV's. I KNOW there is no "X" involved with the props I run.

I got mine over five years ago.

I would call Hydromotive and tell them your set up. They might have some "updated" news that would best fit your own needs.
