ADJUSTMENTS AND FLIGHT TECHNIQUES •OPERATING INSTRUCTIONS. • When adjusting and setting the transmitter functions, connect the receiver and servos, and make the adjustments while observing the operation of the servos. • Alternatively, when studying the operation of transmitter functions, remove the transmitter RF module (to reduce battery drain). The effects of adjustments can be viewed on the SRV program screen (See page 50). • Set the power switch to the ON position.
Setting Instructions 1) Display the standard screen. 2) Reset the Total Timer by pressing the two RES program keys simultaneously. 3) Press the TIM key. The TIMER program screen will appear on the display. The Up Timer will be displayed first. 4) Select the UP (Up), DN (Down), or RYT (Rhythmic) timer mode by pressing the program key. The example shown is for the Up Timer. 5) To set the alarm time, switch to the TIMER SET display by pressing the SET key. Move the cursor to key will cursor keys.
ADJUSTMENTS AND FLIGHT TECHNIQUES TACHO METER Tachometer The tachometer function is used to measure the speed on one to five-bladed propellers, etc. Speed (rpm) is measured up to a maximum of 50,000 rpm fin 20 rpm increments). Setting Method 1) Display the standard screen, and press the program key. 2) Press program key to to select the number of blades. Ex: for a two-bladed propeller.
Back Up Warning When the stored data is lost, the characters "BACK UP" blink on the screen and a buzzer sounds. When the power switch is turned on again, the error display disappears and all the settings return to the factory-set values. When a Back Up error occurs, the back-up lithium battery is probably dead, or there is trouble in the system. To locate the cause, call your Futaba service center. The back up lithium battery life depends on the usage state, but is about 5 years.
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.
Battery Fail Safe Setting 1) Set the Failsafe position on the throttle channel (CH3) as described above. A position slightly above the minimum engine idle speed is recommended. 2) BFS Release Point Setting (When THR is designated as the release channel) • Move the cursor to the B/FS-RESET line of the FAILSAFE screen with the or cursor key. • Select the BFS release channel with the or program key. •Set the throttle stick to the desired BFS release point and press the program key.
ADJUSTMENTS AND FLIGHT TECHNIQUES ADJUSTABLE TRAVEL VOLUME • The ATV function is used to adjust servo travel limits. Servo travel can be adjusted independently in each direction from neutral. Adjustment from 30% to 110% of normal full travel (throw) is possible. • NOTE: When servo travel is changed by ATV, the limits of trim throw and the Dual Rate ON (Low Rate) limits are increased or reduced by the same percentage. • ATV limits are displayed by a bar graph and numbers.
ADJUSTABLE FUNCTION RATE AFR is a servo endpoint limiting function, similar to A TV with one exception: AFR limits only the Dual Rate OFF (High-Rate) servo travel. Trim throw/and Dual Rate ON (Low Rate) limits are unaffected (unless AFR is reduced below the D/R ON limit). Setting Method 1) The setting method for AFR is the same as for ATV (See page 16). 2) Select the EDIT screen and press the AFR program key.
ADJUSTMENTS AND FLIGHT TECHNIQUES DUAL RATE Dual Rate functions allow the modeler to switch servo travel limits in flight, thus varying the control sensitivity for different flight conditions or maneuvers. • Dual Rate functions are available on CH1 (Aileron), CH2 (Elevator), and CH4 (Rudder/Tail Rotor). • Dual Rate ON (Low Rate) limits can be adjusted from 30% to 100% of full throw. • If servo travel is reduced by ATV, the D/R ON throw will be 30% to 100% of the limit set by ATV (in D/R OFF).
Auto Dual Rate • Dual Rate functions may be switched ON and OFF automatically, according to the Throttle (CH3) control stick position. OFF Switch is set to OFF, Dual Rate will be OFF. • If the assigned D/R ON/OFF Switch is set to ON, then D/R will be ON even if the Throttle stick is still below the ON/OFF point. 6) When the Throttle stick is moved above the ON/OFF point, then D/R will be ON, regardless of the position of the D/R ON/OFF Switch.
ADJUSTMENTS AND FLIGHT TECHNIQUES Select the EDIT screen, and move the cursor to Line 2 with the Exponential Mixing Trim Parameter Model or cursor key. End EXPONENTIAL/VTR Exponential or VTR functions can be used to change the servo response curve from the normal Iinear operation. This can be very helpful if control response is either sluggish or too sensitive near the neutral position. Maximum servo deflection limits (set by ATV and/or AFR) remain the same.
TYPE 1 Positive With this type of curve, control response will be made more sensitive near neutral and less sensitive as the stick is deflected farther towards its extreme limits. TYPE 1 Negative TYPE 2 Positive With this type of curve, response will be most sensitive at the LOW end of control stick travel, and decrease as the stick is moved toward HIGH.
ADJUSTMENTS AND FLIGHT TECHNIQUES MIXING • Mixing allows two or more channels to be controlled by a single transmitter control stick or lever. This set features Programmable Mixing with four independent mixing circuits, along with special built-in mixing circuits. • NOTE: Only PROG-MIX Programable Mixing can be used in the BASIC Parameter mode. (See PARAMETER, page 46). •There are five types of mixing (including Prog. Mixing).
PROGRAMABLE MIX Programmable Mixing Four separate Programmable Mixing circuits allow almost infinite mixing combinations. The features of this program provide the modeler with unlimited versatility in trimming and controlling complex, high-performance models. • Mixing of any two channels is possible. • Four completely independent mixing circuits are available. • Mixing amounts can be adjusted independently in either direction from neutral or offset point. •The PROG-MIX ON/OFF Switch can be selected.

Indicates that Master channel is "slaved" to another circuit. 2) To activate XON or YON mixing, press the or key, The character will appear next to the appropriate channel on the left side of the screen to indicate that or has been set. •Combinations allow more efficient use of the number of mixing circuits. An example is shown below.
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 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.
