TTX402 TRANSMITTER ( Tx ) The TTX402 4-Channel Micro airplane transmitter can be confi gured to operate as a 3-channel or 4-channel Tx. 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.
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.

THROTTLE (CH3) Controls the speed (R.P.M.) at which the motor operates. Pushing the throttle stick forward will cause the motor’s speed to increase. Pulling the throttle stick back will cause the motor’s speed to decrease. Always place the throttle stick at the low position before switching on the transmitter.

BUILT-IN 1S LIPO CHARGER A 1S LiPo charger is built into the TTX402 transmitter itself. This charger is designed specifi cally for charging a micro 1S 3.7V LiPo cell having a micro connector. Charge current is rated at 250mAh, with a maximum charge voltage of 4.20V. Charging will begin automatically when the battery is connected, and automatically stop when full charge is detected.

Tactic TSX21 Linear Servo Actuator (TACM0021), and an external brushless ESC. BIND THE RECEIVER TO THE TRANSMITTER If included with the TTX402, the TR421 Rx will auto-bind with the transmitter once powered. This bind ensures sole communication between the two, and prevents other transmitters from controlling your model.
6). If the Tx is confi gured for 4ch operation, connecting a linear actuator servo to this socket will allow for control of an airplane’s aileron surface (as well as elevator, rudder, and throttle). See your local retailer for Tactic’s TSX21 Linear Actuator Servo (TACM0021), which connects directly to this slot.
USING AN OPTIONAL BRUSHLESS ESC: A socket is provided on the Rx Control Board for the connection of an external 1S brushless electronic speed control. To use the Rx Control Board with a brushless ESC instead of the on-board brushed ESC, simply connect the brushless ESC to this socket.
FLYING THE AIRCRAFT 1. Once all setup procedures have been confi rmed, and power has been removed from the model and transmitter, re-attach the propeller to the model. IMPORTANT: Be very careful to stay clear from moving propellers!! 2. Make sure the airplane’s power batteries are fully charged. 3.

2009 OFFICIAL ACADEMY OF MODEL AERONAUTICS NATIONAL MODEL AIRCRAFT SAFETY CODE Effective January 1, 2006 GENERAL 1. A model aircraft shall be defined as a non-human-carrying device capable of sustained flight in the atmosphere. It shall not exceed limitations established in this code and is intended to be used exclusively for recreational or competition activity.
RADIO CONTROL 1. All model fl ying shall be conducted in a manner to avoid overfl ight of unprotected people. 2. I will have completed a successful radio equipment ground-range check before the fi rst fl ight of a new or repaired model aircraft. 3.
● Do not allow chemicals to come in contact with any parts of the radio system. Substances such as glow fuel, gasoline, CA glue, etc. could permanently damage plastic parts of the radio system. ● If NiCd batteries were installed in the transmitter, remove the batteries before placing the radio in long-term storage.
Tactic warrants this product to be free from defects in materials and workmanship for a period of one (1) year from the date of purchase. During that period, Tactic will, at its option, repair or replace without service charge any product deemed defective due to those causes.
