100mm sky trainer 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 After the introduction of four fantastic 1100mm warbirds, Arrows Hobby is proud to announce the first trainer aircraft in the lineup! 6 months in the making, the 1100mm Sky Trainer is the perfect scale-looking trainer! Like traditional trainers, the 1100mm Sky Trainer has inherently easy and stable flight characteristics. Unlike traditional trainers, Arrows Hobby has added scale cockpit details, tricycle landing gears, struts and even functional flaps for unmatched slow-flight performance.
Model assembly Horizontal stabilizer installation 1.Install the horizontal stabilizer to the fuselage slot and secure it with foam safe CA. Required Adhesives: Medium CA Vertical stabilizer installation 1.Install the vertical stabilizer to the fuselage slot and secure it with foam safe CA. Required Adhesives: Medium CA Landing gear set installation 1.Insert the nose landing gear into its slot and secure the assembly using the included set screw.
Model assembly 2.With the left main landing gear strut pointing directly downwards from the fuselage, insert the landing gear assembly into the fuselage landing gear slot and pivot 90 degrees to lock the landing gear in place. 3.Insert the plastic landing gear clips into the gear slot, note that the two pieces are mirrored and only fit into either the left or the right side. Main wing installation 1.Install the left and right main wing struts onto the fuselage, secure them with the included R clips.
Model assembly 2.Using the included Y harnesses, connected the two aileron servos and the two flap servos. Insert the wiring into the fuselage pass through, then insert the wing on to the fuselage and secure with the included screws. 3.Connect the wing struts to the eyelets located on the wings, then secure using included R clips. Antenna installation 1.Install the antenna to the fuselage slot and secure it with foam safe CA. Required Adhesives: Medium CA 06 HKM3.
Model assembly Pushrod installation 1.With the elevator servo centered, connect the elevator servo to the elevator using the included linkage. 2.With the rudder servo centered, connect the rudder servo to the rudder using the included linkage. Propeller installation d c a 1.Assemble the spinner and propeller as shown. Note:the motor should rotate clockwise when viewing the plane from the rear.
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 sky trainer 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.
