Instruction Manual. KA8-B INTRODUCTION. Thank you for choosing the KA8-B ARTF by SEAGULL MODELS. The KA8-B was designed with the sports trainer flyer in mind. It is a High-wing aeroplane which is easy to fly and quick to assemble. The airframe is conventionally built using balsa, plywood and veneer to make it stronger than the average ARTF , yet the design allows the aeroplane to be kept light. You will find that most of the work has been done for you already.
