Kit Contents

Before assembly, inspect all parts against the kit contents list. Key components include the fuselage, main wing, horizontal and vertical stabilizers, propeller set, landing gear, and optional float set.

Model Assembly

Landing Gear Installation

With the fuselage bottom facing up, install the landing gear into the designated slot and secure it with the provided screws.

Main Wing Installation

Slide the wing spar into the fuselage, attach both wings, connect the servo and LED leads, and secure the wings and supporting bars with the included screws.

Tail Installation

Install the horizontal and vertical stabilizers into the rear slots of the fuselage. Secure them with the provided screws and connect the tail struts and tail wheel assembly.

Propeller and Antenna Installation

Install the spinner backplate, propeller, and spinner adapter. Secure the spinner with the screw. Insert the scale antennas into the wing slots and slide them to lock.

Float Set Installation

Assemble the float struts and cross members, then attach the float set to the bottom of the fuselage. Connect the float servo lead to the rudder extension.

Battery and Receiver Setup

Use a 11.1V 2200-3200mAh 50C Li-Po battery. Ensure the battery is secured in the compartment and the center of gravity (CG) is balanced. The recommended CG is 60-70mm from the leading edge of the main wing. Connect servo cables to the receiver according to the provided diagram.

Transmitter and ESC Setup

Bind your receiver to your transmitter. Ensure all control sticks are in neutral and the throttle is in the OFF position. The included ESC is pre-connected but may require calibration. The ESC supports programming via an optional ZTW app or programming card.

Flying the Model

Perform a range check before every flight. During takeoff, apply power slowly to keep the model straight. Monitor flight time using a timer (recommended 4 minutes for the first flight). Land the model when the motor pulses (LVC) or when the timer expires.

Maintenance and Troubleshooting

Regularly check that all screws are tightened and the spinner is secure. Repair foam parts using foam-safe adhesives. If the aircraft does not respond, check the ESC arming, battery charge, and transmitter settings.
