64mm Marlin Operating Manual
Warning: This manual contains important information that will help you maintain and operate your model aircraft in a reliable and safe manner. Please read the instructions and warnings carefully prior to assembly, setup or use. As this model aircraft is a sophisticated hobby product, it must be flown with safety and common sense in mind, failure in doing so may result in injury or property damage. This product is not intended for use by children without direct adult supervision.
Introduction Arrows Hobby 64mm Marlin- The perfect entry-level jet! As a successor to the Arrows Hobby lineup of WWII warbirds and trainers, the Arrows Hobby engineers have decided to tackle the impossible- a jet that flies as easily as the best high winged trainers on the market.
Model assembly Wing installation HKM3.0*20mm 1. Attach the wing onto the fuselage, ensuring not to pinch any of the servo wires. 2.Secure the wing to the fuselage with included screws as shown. Do not over tighten the screws. Landing gear installation 1.Insert the landing gear assembly into the wing landing gear slot and pivot 90 degrees to lock the landing gear in place.
Model assembly Horizontal stabilizer installation 1.Connect the elevator servo connectors to the servo extensions in the fuselage. HKM3.0*20mm 2.Attach the horizontal stabilizer in the rear of the fuselage and secure it in place using the included screws. Ensure the control horn faces down as shown.
Battery installation 1. Remove the battery hatch. 2. Remove the hook and loop tape from the fuselage. Apply the looped surface to the battery. 3. Install the battery into the fuselage- securing it with the preinstalled battery straps. Note: The weight of each battery may vary due to different manufacturing techniques. Move the battery fore or aft to achieve the optimal center of gravity. Receiver diagram The cables from the servo connector board should be connected to your receiver in the order shown.
Preflight check transmitter and model setup After assembly and prior to your first flight, make sure all control surfaces respond correctly to your transmitter by referring to the diagram below. Control throws The suggested control throw setting for the Marlin are as follows (dual rate setting): Tip: The maiden flight should always be flown using low rates, fly the aircraft until you are familiar with its characteristics prior to trying high rates.
Control horn and servo arm settings 1. The table shows the factory settings for the control horns and servo arms. Fly the aircraft at the factory settings before making changes. 2. After flying, you may choose to adjust the linkage positions for the desired control response. Ailerons Rudder Elevator Horns Arms More control throw Less control throw Finding the center of gravity Finding the correct center of gravity is critical in ensuring that the aircraft performs in a stable and responsive manner.
Before flying the model Always turn your transmitter on first. Install a fully charged battery in the battery bay, then connect it to the ESC. In this process, make sure that the throttle cut functionality is on, and that the throttle stick is secured in its lowest position- otherwise, the propeller/fan will engage and possibly cause bodily harm. Note: Please refer to your transmitter manual that came with your radio control system to perform a ground range check.
Troubleshooting Problem Possible Cause Solution Aircraft will not respond to the throttle but responds to other controls. ESC is not armed. Throttle channel is reversed. Lower throttle stick and throttle trim to lowest settings. Reverse throttle channel on transmitter. Excessive vibration or propeller noise. Damaged spinner, propeller, motor or motor mount. Loose propeller and spinner parts. Propellor installed backwards. Replace damaged parts.
