The fuselage and tail are welded from 4130 steel tube. There are two main wing configurations that can be built. An aluminum wing spar with hinges allows the wings to be folded for trailering or storage. A wooden wing spar configuration gives the plane a lighter weight, but leaves the wings fixed. The engine cowling is made from fiberglass.〔 The aircraft has had many engine choices available, but was marketed to use the Half VW engine first developed by Global engines, later bought by Mosler engines and finally marketed by TEC engines.〔(Global Machine Tool (US) )〕 The Total Engine Concepts MM CB-40 was the last purpose-built engine marketed for the Pup.
