A clean-sheet design for private pilots

Computational fluid dynamics including longitudinal stability using USM3D Navier-Stokes.

Finite element analysis completed.  CFR-title 14, subpart 23 using AGATE design allowables.

Preliminary and critical design reviews completed including dynamic stability.

Safety and Performance

Predictable flight characteristics with excellent spin resistance and recovery.

Highest IO-360 speed possible while having a 50mph stall with standard flaps.
