ULTIMATE. Instruction Manual. INTRODUCTION. Thank you for choosing the ULTIMATE ARTF by SEAGULL MODELS. The ULTIMATE was 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 that most of the work has been done for you already.
www.seagullmodels.com NOTE: To avoid scratching your new aeroplane we suggest that you cover your workbench with an old towel. Keep a couple of jars or bowls handy to hold the small parts after you open the bags. Please trial fit all parts. Make sure you have the correct parts and that they fit and are aligned properly before gluing! This will ensure proper assembly as the ULTIMATE is made from natural materials and minor adjustments may have to be made.
ULTIMATE. Instruction Manual. 5) Turn the wing panel over and deflect the aileron in the opposite direction from the opposite side. Apply thin C/A glue to each hinge, making sure that the C/A penetrates into both the aileron and wing panel. 6) Using C/A remover/debonder and a paper towel, remove any excess C/A glue that may have accumulated on the wing or in the aileron hinge area. 7) Repeat this process with the other wing panel, securely hinging the aileron in place.
