The Hobbico Avistar Select outfit has the wing that does not need to be glued together. That wing uses a steel rod as the carry-through support and is not glued. The wing halves are held together with a strap and screws. The verical and horizontal tail surfaces also bolt to the fuselage. The "Select" series of Hobbico R/C airplanes come virtually ready to fly. Minimal assembly and then charge the batteries and go!

The Hobbico Avistar ARF requires that you glue the wing halves together and use a plywood dihedral brace as the carry-through support. You also have to glue on the vertical and horizontal tail surfaces. Of course, the model does not have the engine and R/C system already installed.

Both models are the same airplane, but the construction has been executed in slightly-different ways. The Select version does not require glueing of any kind, and assembly is very fast. The other version requires more work by the modeler.

In either case, just follow the instruction book and you'll be fine.
