Users Manual

The Tactic™ TTX403 Micro airplane radio system uses an advanced 2.4GHz spread spectrum technology to prevent unwanted outside interference from interrupting control of the model, ensuring error-free fl ying and eliminating the need to pull frequency pins before every fl ight. Tactic 2.4GHz transmitters and receivers are not compatible with other brand 2.4GHz equipment. For safe operation and best results, it’s strongly recommended to read this manual in its entirety before use ! Also read and understand the instructions included with the model. Damage resulting from misuse or modifi cation will void your warranty.

When confi gured for 4-channel operation the controls function like a normal Mode-2 transmitter with aileron + elevator on the right stick, and throttle + rudder on the left stick. Confi guring the Tx for 3-channel operation can help beginners concentrate on throttle control with one hand and full airplane directional control with the other hand. Here, the right stick operates elevator + rudder while the left stick will control the throttle. The aileron function will still be active, and now be on the left stick, but aileron control is often not needed for 3ch aircraft. To change the TTX403 transmitter between 3ch and 4ch confi gurations: 1. Turn off the Tx power switch. 2. Move the right stick to the top- right corner, and the left stick to the top-left corner, and hold in these positions. 3. Move the Tx power switch to the on position. The power LED will fl ash, accompanied by three short tones from the Tx which indicates the Tx confi guration has been changed. NOTE: Each time the Tx power switch is turned on you will hear either one short tone if the Tx is in the 3ch configuration, or two short tones if the Tx is in the 4ch configuration. Input Power Five “AA” batteries are required to power the Tx (not included with individual radio systems). Non-rechargeable 1.5V alkaline, or 1.2V rechargeable nickel-cadmium (NiCd) or nickel-metal hydride (NiMH) cells can be used. Do not mix cell types, old and new cells, etc. See the SERVOS AND ACCESSORIES section on page 12 for optional products available at local hobby retailers. 3 Slide the battery door down, and insert the cells as shown. Make sure to note proper polarity for each cell. Close the battery door. Power LED and Low Battery Alarm The red power LED should light when the power switch is moved upwards to the on position. The Tx should have adequate power for fl ight when the LED is on constantly. Anytime the LED begins to fl ash, accompanied by an audible tone, the Tx battery voltage has dropped too low and operation of the model should NOT be attempted! WARNING! Never operate an R/C model with weak Tx batteries! Reduced operational range and/or possible loss of control of the aircraft could result. Replace weak alkaline batteries, or recharge NiCd or NiMH batteries before attempting a fl ight! If during a fl ight audible tones sound and the Tx LED starts to fl ash the Tx batteries have become weak and the aircraft should be landed as soon as possible! Aileron (Ch 1) Controls the moveable surfaces at the trailing edge of the main wings to rotate the airplane about the “roll” axis (an imaginary line which extends from the airplane’s nose to the tail). Since every airplane is different, the direction of movement for the aileron channel may need to be reversed so that moving the aileron stick to the right will cause the airplane’s right aileron to defl ect up, thus causing the right wing to drop and the airplane will bank to the right. Moving the aileron stick to the left will cause the airplane’s left wing to drop and the airplane will bank to the left. This is one important method for turning the aircraft. When the Tx is set to the 3ch confi guration the aileron channel will not be used. Elevator (Ch 2) Controls the moveable horizontal surfaces on the airplane’s tail to rotate the airplane about the “pitch” axis (an imaginary line extending through the center of both main wings, from one wing tip to the other wing tip). The direction of movement for the elevator channel may need to be reversed so that pulling the elevator stick back (towards you) will cause the elevator to defl ect up, thus causing the nose of the 4 airplane to rise. Pushing the elevator stick forwards (away from you) will cause the nose of the airplane to drop. Throttle (Ch 3) Controls the speed (R.P.M.) at which the motor operates. Pulling the throttle stick back will cause the motor’s speed to decrease. Pushing the throttle stick forward will cause the motor’s speed to increase. Rudder (Ch 4) Controls the side-to-side movement of the airplane’s tail and will rotate the airplane about the “yaw axis” (an imaginary line from the top of the airplane’s fuselage to the bottom of the fuselage, located near the center-point of the fuselage). The direction of movement for the rudder channel may need to be reversed so that moving the rudder stick …
