RE: OMP Hybrid Edge 540 Build
I built one a couple years ago. I have a MVVS Prosport 58 in it. It flies like a giant foamy. Mine turned out to be 16 pounds, 7 ounces.
It's my favorite fun-fly plane.
For a light plane and huge wing, I was surprised that it has wing rock in the high alfa stuff. The only thing I would do differently is move the horizontal stab and elevator ahead a couple inches. The elevator shape should be changed a bit to fit the modification.That should be a simple fix.
