08/31/2014. Remarks by Walter van Tilborg: "N824G was built by Arlington Aircraft Development as SH-4 (c/n 01-P) in 1994, its airworthiness date was February 13, 1997. It is the prototype of the GlaStar series and has a Lycoming O-320 engine. The aircraft is at present registered in the name of the EAA Aviation Foundation, Inc., to which it was donated in 1999.
The SH-4 GlaStar (capital G and S) was designed by Stoddard-Hamilton Aircraft, Inc. and the first high wing type of the company. The GlaStar had a mixed construction, with a steel tube fuselage, metal wings and composite material fuselage shells and the type was available in kit form with a built-in provision to complete the aircraft with a tricycle or tail wheel undercarriage, in the builder's choice. The prototype GlaStar used an 125 hp Continental IO-240-A engine and (with a tricycle type undercarriage) first flew November 29, 1994. The same aircraft also flew with a tail wheel undercarriage in late-1995 and in 1997 underwent trials with several makes of floats. During the test program, a slightly taller vertical tail and rudder introduced and in 1996 it was finally fitted with an 160 hp Lycoming IO-320.
Stoddard-Hamilton ceased operations in 2000, but was soon followed by the newly founded New GlaStar, LLC (operating as Glasair Aviation, LLC) which continued development and production and which also launched a so called 2+2 variant as GS-2 Sportsman. During late-2012 the company was acquired by the Jiling Hanxing Group (Zhuhai Hanxing General Aviation Co. Ltd.) of China and was renamed as Glasair Aviation USA, LLC. The German OMF Model 160 Symfony was a development of the GlaStar."
