User manual FUTABA 4YF

[. . . ] In the US, use of 72MHz (aircraft only), 75MHz (ground models only) and 27MHz (both) frequency bands are strictly regulated by the FCC. This equipment must not be utilized to operate equipment other than radio controlled models. Similarly, other frequencies (except 50MHz, for HAM operators) must not be used to operate models. Modification, adjustment, and replacement of parts: Futaba is not responsible for unauthorized modification, adjustment, and replacement of parts on this product. [. . . ] Also, do not disassemble or rebuild the nicd battery. Breakage, overheating, and electrolyte leakage may cause injury, burns, or blindness. 4 When not flying the model, store the digital proportional R/C set with the nicd battery in the discharged state. Recharge the nicd battery before the next flight. If a partially discharged nicd battery is recharged many times, its memory effect will reduce the flight time substantially and may cause a crash, even if the battery is recharged. Nicd battery electrolyte The electrolyte in the nicd battery is a strong alkali and can cause blindness if it gets in the eyes. If you get the electrolyte in your eyes, immediately wash your eyes with water and see a doctor. If you get the electrolyte on your skin or clothes, it may cause a burn. Immediately wash it off with water. CAUTION Do not store the digital proportional R/C set in the following places: -Where it is very hot (40C/104F or more) or very cold (-10C/-14F or less). Storing the digital proportional R/C set in the places above may cause distortion and trouble. If the digital proportional R/C set will not be used for a long time, remove the batteries from the transmitter and the model and store them in a dry place. If the batteries are left in the transmitter and model, the battery electrolyte may leak out and degrade the performance and shorten the life of the transmitter and model. Nicd battery recycling Used nicd batteries are an important resource. : Normal side 7 BEFORE USE TRANSMITTER T4YF (Rear Panel) Trainer jack Connects the trainer cord when using the trainer function. ) (See page 15 for the trainer function operation instructions. ) BEFORE USE Battery cover Use when replacing the battery .

If a long screw is used, the interior of the servo may be damaged. 9 BEFORE USE Transmitter Operation and Movement of Each Servo Before making any adjustments, learn the operation of the transmitter and the movement of each servo. (In the following descriptions, the transmitter is assumed to be in the standby state. ) AILERON OPERATION When the aileron stick is moved to the right, the right aileron is raised and the left aileron is lowered, relative to the direction of flight, and the plane turns to the right. When the aileron stick is moved to the left, the ailerons move in the opposite direction. To level the plane, the aileron stick must be moved in the opposite direction. ELEVATOR OPERATION When the elevator stick is pulled back, the tail elevator is raised and the tail of the plane is forced down, the air flow applied to the wings is changed, the lifting force is increased, and the plane climbs (UP operation). When the elevator stick is pushed forward, the elevator is lowered, the tail of the plane is forced up, the air flow applied to the wings is changed, the lifting force is decreased, and the plane dives (DOWN operation). THROTTLE OPERATION When the throttle stick is pulled back, the engine throttle lever arm moves to the SLOW (low speed) side. When the throttle stick is pushed forward, the throttle lever arm moves to the HIGH (high speed) side. RUDDER OPERATION When the rudder stick is moved to the right, the rudder moves to the right and the nose points to the right, relative to the direction of flight. When the rudder stick is moved to the left, the rudder moves to the left and the nose points to the left and the direction of travel of the plane changes. Aileron(ch1) (Viewed from the rear) Left Left Right Right BEFORE USE Elevator(ch2) Down Down Down Up Up Up (Mode 1) (Mode 2) Throttle(ch3) High High High Engine throttle lever moves to the high speed side. Low Low Low (Mode 1) (Mode 2) Engine throttle lever moves to the low speed side.

[. . . ] It is the direction in which the trailing edge of the elevator is pointing down. Rod A bar that connects the servos and the fuselage control surfaces. Elevator (ELE. ) Control surface that moves up and down on the horizontal stabilizer of an aircraft. It usually controls up and down. Servo horn A part that is installed to the shaft of a servo and changes the rotating motion of the servo to linear motion and transmits the linear motion to a rod. Servo horns come in various shapes. Linkage Mechanism that connects the servos and the fuselage control surfaces. Servo mount Fuselage base for installing a servo to the fuselage. Modulation method Two modulation methods are used with radio control: AM (Amplitude Modulation) and FM (Frequency Modulation). Another method that encodes and transmits the modulated signals is called "PCM". Stick Rod for operating the transmitter. Throttle (THR. ) Part that controls the air mixture at the engine intake.
