Instruction Manual. ULTRA JET INTRODUCTION. Thank you for choosing the ULTRA JET ARTF by SEAGULL MODELS COMPANY LTD. The ULTRA JET was designed with the intermediate/advanced sport flyer in mind. It is a not 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 that most of the work has been done for you already.
