Eklund Engineering, Inc. is an aero-mechanical consulting firm which holds the rights to the Thorp T-18 and John Thorp's engineering legacy.
The Thorp T-18 was designed by John Willard Thorp as the first good all metal homebuilt design. The two place side by side design was first envisioned as an open cockpit, uncowled, simple to build sport plane to use the converted Lycoming O-290G ground power engine. It soon grew into a high performance design which incorporated pressure cowl, canopy and slotted flaps. The T-18 can use any of the Lycoming engines in the following series: O-290, 320, 340, 360.
