Pre-flight check

Checking the current setup

1. Assure that the transmitter is turned on (both the LEDs are on with the T8FB). Place all the trims in their neutral positions and set the throttle stick into the lowest position. Connect the flight pack to the ESC - the red LED on the receiver must glow. If it blinks or does not glow at all, the receiver and transmitter require establishing their link by the binding procedure - refer to page 6 in this manual.

2. Checking the control surface neutrals
   Please check that all the control surfaces are in the neutral position if the corresponding transmitter sticks and trims are in the centre position. If not, please loosen the setting screw of the corresponding push rod connector and set the control surface to the neutral position. The elevator and rudder have to be flush with the horizontal stabilizer (the fin). Both two ailerons have to be flush with the wing trailing edge. Once satisfied, apply a drop of threadlocker to the setting screw a tighten it.

   Caution: If the quick link gets loose during flight, your model will become partly or completely uncontrollable. Therefore, you should check the linkage regularly.

3. Testing the ailerons
   A. Move the aileron stick to the left; (looking from the tail to the nose) the left aileron must move up and the right aileron must drop down simultaneously.
   B. Move the aileron stick to the right; the left aileron must drop down and the right aileron must go up simultaneously.
   C. Return the aileron stick to the centre (neutral) - both two ailerons will return to the neutral position.

   Note: If the ailerons are moving in the opposite direction, you will have to reverse the direction by flipping the aileron reverse switch (AIL) on your transmitter.

4. Testing the rudder
   A. Move the rudder stick to the left; (looking from the tail to the nose) the rudder must move to the left.
   B. Move the rudder stick to the right; the rudder must move to the right.
   C. Return the rudder stick to the centre (neutral) - the rudder will return to the neutral position.

   Note: If the rudder is moving in the opposite direction, you will have to reverse the direction by flipping the rudder reverse switch (RUD) on your transmitter.

5. Testing the elevator
   A. The elevator stick is located on the left side of the Mode 1 transmitter or on the right side of the Mode 2 transmitter. Pull the elevator stick down; the elevator must move up).
   B. Push the elevator stick up; the elevator must move down.
   C. Return the elevator stick to the centre (neutral) - the elevator will return to the neutral position.

   Note: If the elevator is moving in the opposite direction, you will have to reverse the direction by flipping the elevator reverse switch (ELE) on your transmitter.
