Overview The focus of this project was to model an existing

SOLO-1 ARF (Almost Ready-to Fly) remote control airplane that is approximately fifteen years old.

The aircraft is equipped with a three point fixed landing gear system.

The controls consist of three servos that operate the throttle, elevator, and the rudder/front wheel steering.

The wing has a uniform cross section with a slight rise from tip to tip. Thrust is generated by the Saito FA-40 engine, which consists of many intricate components which work together to power propeller.
