INTRODUCTION.

Thank you for choosing the 

RYAN NAVION

designed with the intermediate/advanced sport flyer in mind. It is a  semi scale airplane  which is easy
to fly and quick to assemble. The airframe is conventionally built using balsa, plywood to make it
stronger than the average ARTF , yet the design allows the aeroplane to be kept light. You will find

are pre-installed . Flying the 

RYAN NAVION
