Introduction

Meet the aircraft

The SeaMax M-22 is a light sport amphibian designed around both water and land operations. Its cockpit canopy provides a broad forward view, while retractable landing gear and a retractable water rudder serve its two operating environments. JRollon reports working with the real aircraft’s designer on the simulator model.

SeaMax support and water-handling limits

JRollon reports working with the real aircraft’s designer on the simulator model. This is an older product: his page says X-Plane 11 operation requires an updated file from the support forum and notes limitations in its water handling.

HOW IT CAME TO BE

History & design

Miguel Rosário’s twenty-second design

Seamax’s historical account dates the M-22 concept to 1998 and prototype-development work to 2001. The first aircraft was delivered in 2002. Its number reflects designer Miguel Rosário’s twenty-second project.

Seamax M-22 manufacturer history and equipment

A later company continues the aircraft

The company formed in 2017 acquired the M-22 intellectual property and brought Rosário into the business. That corporate date is therefore not the beginning of the airframe’s development. The manufacturer’s account describes resuming and expanding production of an already established aircraft.

Systems & details

Reading an older simulator implementation

JRollon describes help from the aircraft’s designer, plus a bilge pump, retractable water rudder and gear-viewing mirrors in the simulation. This is an older product account with older X-Plane compatibility statements; it does not establish current XP12 compatibility or inclusion of later M-22 factory changes.
