Flown the Tribute. Very nice 3D plane. The wings flex a lot but not a problem.
The way the motor attaches to the carbon tube is a weak spot. In a crash the tube often breaks.
Could be reinforced with a couple tubes down the sides behind the motor or something to make it stronger.
I think you will like the plane. I found it a lot of fun to fly. Sounds like a good deal if the plane is in good shape.
