The Beaulieus were
great cameras.... but notorious battery hogs, especially at high speed (and most took proprietary batteries) so be sure you have plenty of juice.
And yes, they will run up to 80fps, but resist the urge to
ever run the camera without film (even as a short "Is thing thing working?" test) at anything above 24fps. Many a Beaulieu has been seriously damaged by doing that. And while they were very expensive-to-buy cameras in their day, they are even more costly to repair.
Good luck!
