[13] ADJUSTMENTS AND FLIGHT TECHNIQUES REVERSE Servo Reversing This function is used to change the direction of servo operation in relation to control stick or /ever movement. Setting Method 1) Select the EDIT screen, the select the REVERSE screen by pressing the program key. 2) Select the desired channel with the and cursor keys. 3) Select NORMAL or REVERSE operation by pressing the or program key. In the display example, (Rudder) is set to REVERSE. 4) Return to the EDIT screen by pressing the program key. FAIL SAFE Fail Safe Fail Safe and Hold Functions The HOLD (Hold) and F/S (Failsafe) functions are designed to allow the aircraft or helicopter to "fly through" a momentary loss of signal or very strong interference, rather than experiencing the familiar "glitch" as the servos react violently to the unwanted signal. These functions cannot be expected to prevent a crash however, if the normal signal interruption is of sufficient duration. The HOLD function stops the servo at the position held just before the normal signal is lost. When a normal signal is again received, the Hold function is released. The FAILSAFE function will move a servo to neutral or a pre-set position when the normal signal is interrupted for 1 second or longer (The system will remain in HOLD for the first 1 second of signal loss). When a normal signal resumes, FAILSAFE is released. BFS (Battery Fail Safe) Function The BFS function moves the throttle (CH3) servo to the pre-set Fail Safe position when the airborne power supply is nearly exhausted. If no Fail Safe position has been set, the throttle servo will move to medium slow (neutral). BFS can be released by lowering the throttle Stick past the release point (adjustable), or with the CH9 switch. Throttle control is then regained for about 30 seconds. At the end of 30 seconds, BFS will re-engage and the throttle will again move to the Fail Safe position. Whenever BFS engages, land the aircraft as quickly as possible and recharge or replace the Nicd battery pack. [14] Fail Safe and Hold General Instructions Fail Safe · F/S or HOLD can be selected for each channel (1 to 8). ·Channels selected for HOLD will remain in HOLD until a normal signal resumes. Those selected for F/S will move to their pre-set positions after 1 second of signal interruption. · F/S SET simultaneously stores the desired Fail Safe position in the transmitter memory and sends it to the receiver. ·The F/S data is automatically sent to the receiver when the transmitter is first turned ON and at one minute intervals as long as the transmitter is left on. [. . . ] This is the same as AIL -> ELV -> RUD mixing. Setting MX1 as the MX2 Master channel in the example is the same as setting · Combinations are effective when the number of mixing circuits is insufficient, and when PROG-MIX circuits are mixed with built-in mixing circuits. ADJUSTMENTS AND FLIGHT TECHNIQUES · Activation of Programmable Mixing Circuits 1) Move the cursor to the "INH" position with the or cursor key. 2) To activate the circuit, press the key. "ON" or "OFF" will be displayed according to the position of the designated Mixing ON/ OFF Switch. 3) To deactivate the mixinq circuit, press the program key. Mixing Rate and Direction Setting The mixing rate setting determines the amount of deflection of the Slave servo in relation to movement of the Master channel control stick or lever. Both the amount (rate) and direction (+ or -) of movement can be set independently, either side of the mixing point (neutral). [. . . ]
