Just 2 screws hold the tail on my Dynam Me-262.... and it handles 110mph +
(EPO foam model)

Filling a gap to eliminate slop is always a good idea. If it wobbles it will flutter.
Shouldn't be necessary on a modern molded foam model though.

Flexible material will eventually flutter. Just a question of what airspeed.

You can induce flutter with rapid control movements, aggravating the flex of the structure. That's what the video looked like. The gyro's excess gain started a rapid servo oscillation which made the tail-planes start flexing and it progressed from there. After flutter was initiated, the gyro was still trying to smooth the flight path and maintained the flutter.

The only way to stop flutter is slow down to a point where the surface isn't flexing.
