Nice Edge Jason. Not sure whether this is going to help you, but I usually prefer to receive more info than less..... even if it is half applicable...
I am currently building a Lanier Laser 200 33%, wingspan 2,44m, suggestion from the manual is a ZG62 or similar. When gathering info for this plane, I found these links:

In post number 6 from Yukon Bob you will find that he had the best results with the GT80 on the Lanier Laser.

with a nice video, flying great with a 3W75us
and in this thread:

a lot of people running a 75-80cc as well. In post #6 Fearless Flyer says he can hover his Laser with 3W75iUS at less than 1/2 throttle with a 26x10 menz prop.
and this one:

hovers at just half throttle with a ZDZ80
I know this is a different plane, but since an Edge is a newer model, I would expect it to be lighter than the Lanier Laser 200, so you should have plenty of power. I am still in the rebuilding phase of my Laser (which had a couple of owners before me) and based upon the threads above I decided to go for the GT-80, found one that later appeared to be a ZG-74, but I will try this engine on the plane.
Did you see this review of the H9 33% Edge?

Good luck in your hunt for information!
