I am only using Unreal to make a movie at this point. I have no control over export frame rate at all from Blender. Only a setting which seems to affect the sample rate, but it has a default of 1.00 But no place is is it explained what 1.00 is. Could be 1000x for all I know. I will have to experiment with that at some point.
At any rate you have been most helpful.
Thanks again!
