Open-cockpit Speedster performance with 4-stroke V-Twin simplicity

The 1200S Speedster Sport is the 4-stroke Mini-Max path for builders who want a sportier single-seat aircraft without leaving the simple wood-and-fabric building approach. Engineering estimates list a 25 FT wingspan, 560 LBS max gross weight, 80 MPH top speed, 70 MPH cruise, and 1200 FPM climb rate.

What the 1200S is

The 1200S Speedster Sport is the 4-Stroke Sport Mini-Max path for builders who want a livelier single-seat aircraft while keeping the build simple and familiar. It keeps the classic Mini-Max wood-and-fabric approach, a compact 25 FT wingspan, and a 24" cockpit listed in current Mini-Max data.

This page is for builders comparing the 1200S as an open-cockpit sport aircraft project with a V-Twin engine direction. Engineering estimates list an 80 MPH top speed, 70 MPH cruise speed, 1200 FPM climb rate, and short-field numbers that keep the aircraft focused on simple, responsive flying.
