Here's what I read about flutter ...

This is another whole article in itself, but for the sake of this writing, just accept the fact that gaps are the cause of flutter about as much as my dog is responsible for WWII.''

Hmm the gap in itself may not cause flutter but as any long time modeller will tell you that flying surfaces with substantial gaps WILL FLUTTER more often than those without. Maybe it is because the hinges flex or some aerodynamic slot effect .
Whatever it is hinge gapes are likely to lead to a second or so of buzzing on a high speed pass followed by bits coming off the model and a lawn dart job.
Keep those hinges tight, horns stiff and pushrods meaty to avoid flutter.
