Throttle control can be adjusted with the ATL trim lever 19 This completes the settings for basic 8 channel use. ·USING ATV (ADJUSTABLE TRAVEL VOLUME) GENERAL - ATV (Adjustable Travel Volume) allows independent adjustment of servo maximum throw in each direction (without affecting the neutral position). This is also sometimes referred to as "separate endpoint adjustment". ATV is very convenient when for example: a model requires more DOWN elevator deflection than UP for equal inside and outside loops (with equal control stick deflection). Other aircraft may require slightly different RIGHT or LEFT aileron or rudder deflection to give equal response in each direction (due to engine torque, precision of the model, etc. ). Two different ATV functions are possible with this system. Memory (Pushbutton) ATV and 2ND ATV. MEMORY (PUSHBUTTON) ATV This type of ATV is available on all eight channels. Servo travel is adjusted as outlined in the example below. NOTE: Memory ATV settings are retained in the transmitter memory circuit even when the power switch is turned OFF. They are lost however, if the transmitter Nicd battery nears full discharge or is removed for servicing. ATV SETTING Switch switches (S), [49] and (R) [48] Fig. 30 MEMORY (PUSHBUTTON) ATV - (Aileron CH1 used as example) First, set Function Select Switch [49] to ATV position. Set Channel Select Switch [48] to 1 (Ail. ). Set the transmitter and receiver power switches ON and check for proper servo operation. Move the Aileron stick to full RIGHT aileron, hold it in that position, and set servo movement to the desired Right aileron deflection angle by pressing Button [46] or 47. For other channels, select the channel with switch 48 and adjust ATV as desired. When all adjustments are completed, set the Function Select and Channel Select switches ([48]and [49]) to OFF. To clear the ATV settings on all channels, set the Function Select switch [49] to RESET and Channel Select switch 48 to POSITION 2 (Pos. 2 = ATV when 49 is on RESET) and press Buttons 46 and 47 simultaneously. ATV is cleared on ALL CHANNELS and servos will move to 100% of their maximum throw. If only one channel is to be cleared or changed, simply repeat Steps I through 5 with Channel Select Switch [48] set to the appropriate channel. ATV/FS BUTTON ·These two pushbutton switches are used for servo deflection angle setting of ATV, FS or HOLD function, servo test start & stop; reset; battery FS memory set, etc. This pushbutton switch is used when: Making the ATV servo deflection angle larger. This pushbutton switch is used when: Making the ATV servo deflection angle smaller. [. . . ] · Use a separate servo on each aileron and connect as shown in Fig. NOTE: Always connect the servo on the Right Aileron to CH1 (Aileron). · Set Switches 16 and 17 as shown in Fig. · Aileron differential can be varied to suit using Trimmer 15 .
