6. One final note about flying your model Have a goal or flight plan in mind for every flight This can be learning a new maneuver s improving a maneuver s you already know or learning how the model behaves in certain conditions such as on high or low rates This is not necessarily to improve your skills though it is never a bad idea but more importantly so you do not surprise yourself by impulsively attempting a maneuver and suddenly finding that you ve run out of time altitude or airspeed Every maneuver should be deliberate not impulsive For example if you re going to do a loop check your altitude mind the wind direction anticipating rudder corrections that will be required to maintain heading remember to throttle back at the top and make certain you are on the desired rates high low rates A flight plan greatly reduces the chances of crashing your model just because of poor planning and impulsive moves Remember to think Have a ball But always stay in control and fly in a safe manner GOOD LUCK AND GREAT FLYING Make a copy of the identification tag shown below and place it on or inside the model This model belongs to Name Address City State Zip Phone number AMA number OTHER ITEMS AVAILABLE FROM GREAT PLANES Great Planes Ultra Sport 40 Plus Kit If you ve progressed past trainers and want an easy to fly sport model with a wide performance range the 58 5 span Ultra Sport 40

R C and other components so that the model operates correctly on the ground and in the air 6 You must check the operation of the model before every flight to insure that all equipment is operating and that the model has remained structurally sound Be sure to check clevises or other connectors often and replace them if they show any signs of wear or fatigue 7 If you are not already an experienced R C pilot you should fly the model only with the help of a competent experienced R C pilot 8 While this kit has been flight tested to exceed normal use if the plane will be used for extremely high stress flying such as racing the modeler is responsible for taking steps to reinforce the high stress points We as the kit manufacturer provide you with a top quality thoroughly tested kit and instructions but ultimately the quality and flyability of your finished model depends on how you build it therefore we cannot in any way guarantee the performance of your completed model and no representations are expressed or implied as to the performance or safety of your completed model Remember Take your time and follow the instructions to end up with a well built model that is straight and true Before starting to build compare the parts in this kit with the Parts List and note any missing parts Also inspect all parts to make sure they are of acceptable quality If any parts are missing broken or defective or if you hav
