The CA-2 is a light all metal legal ultralight (with Rotax 277) aircraft that can be built inexpensively from plans (approximately $2,000-2,500 for airframe) in 600 hours.  Easy construction from sheet, angle extrusions, tubing and pop rivets.  No welding, gluing, machining, or difficult forming required.  Fuselage assembly performed on a flat table and wing assembly using a simple wood jig.

Strong all metal wing (utility category +4.4, -2.2g), smooth push rod controls, large ailerons and rudder, wide landing gear stance for easy ground handling, and wing detaches with removal of three bolts.
