Check me out on this thought.

I was concerned about the angle of the EDF fan in the body. That really has no effect. Only the location and angle of the end of the exhaust stream ??
So a front -bottom- intake to a EDF unit blowing as straight as possible to a foot before the horizontal stabilizer should give me the least trim out out problems ? I Have measured the thrust angle of a rear most exhaust & it is about 5 to 7 degrees of up angle.
