This airplane is made from corrugated plastic (like they make durable signs from). It's basically a commercial SPAD (Simple Plasic Airplane Design) with all the pieces cut-out and smaller hardware included. It's very durable for a model airplane, and flies predictably.

AirCore 40 after 2 flights

This is my first plane. It was built from a flat box kit over a period of about a month, spending a couple of sessions a week on it. You also need 3 rubber wheels, 10x6 propeller, 2 1/2" spinner, and fuel tubing. It was completed in July 2004.
