The Concept

The Panther is designed as a versatile, mid-sized, single seat low wing Sport or LSA aerobatic airplane with quick fold wings

Why?  We all know there are 10 different single seat airplanes in this class, so why do we need another one?  It comes down to compromises. Every designer picks their own set of compromises, whether it be engine choice, construction, technique or building modes (like plans versus kits), just to name a few.  It has always been and always will be a give and take.  The designs in the current market never seemed to fit my set of desired compromises.  They were either too small, very complex to build, designed around a specific engine or could only be kit built.  When thinking in terms of a single seat airplane I always thought there should be an aircraft with a much broader set of compromises.  The Panther offers un-paralleled versatility. The Panther is the Burger King of airplanes, “Have it Your Way”.  You choose the engine, landing gear configuration, wing length, safety features ….you make it how you want it.
