100mm F4U-4 V2 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 The F4U-4 is the last of the legendary Corsairs to serve in WWII. Delivered to the United States Navy in early 1945, the F4U-4 is powered by a Pratt and Whitney R2800-18W supercharged Twin Wasp engine- pushing 2100 horsepower. Retaining the six 12.7mm guns and load carrying capabilities of the F4U-1D, the F4U-4 achieved an unbelievable 11:1 kill ratio during its service life.
Model assembly Wing installation 1.Insert all leads on the wing into the fuselage via the fuselage passthrough. Attach the wing onto the fuselage and ensure that the wires do not interfere with any of the servos. 2.Secure the wing to the fuselage with included screws as shown. Do not over tighten the screws. HKM3.0*40mm Pitot tube installation 1.Carefully apply foam safe CA to the base of the shown pocket and place the pitot tube into the pocket as shown.
Model assembly Auxiliary fuel tank installation 1. Slide the auxiliary fuel tanks into the guide rails on the wing structure. 2. Carefully apply foam-safe CA to the horizontal stabilizer pass-through, then insert the two horizontal stabilizer halves into their slots. Horizontal stabilizer installation 1.Carefully apply foam safe CA to the shown pocket and place the two pieces of horizontal stabilizer into the pocket as shown. Required Adhesives: Medium CA Propeller and spinner installation b 1.
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 F4U-4 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.
