The new Ultrafly Edge 540 (25e) is one of the best 3D models in its class. Constructed of hand-picked light balsa and lite-ply, the fuselage, wing, and tail groups carefully follow the lines of the full-size model. Ultrafly engineer design with their experience and create the best airfoil for the aerobatic performance in this size. Finally you don't have to give up scale beauty for performance. The hand painted fiberglass parts are work of art. The clear canopy on a wood hatch already comes with pre-installed magnetic retention system. Battery access in a few seconds keeps things easy and safe. This model has an extremely light wing loading. Its light weight coupled with a generous wing area, and extremely rigid construction makes this plane a razor sharp performer in the 3D arena. This is the kind of model that gets taken out every weekend. This sharpens the maneuvers of any pilot, and it's especially helpful if your eyes are not "what they used to be". Contrasting stripes on wing bottom really help with orientation.
