EXAMPLES OF PROGRAMMABLE MIXING

Programmable Mixing combinations are extremely versatile and can be as complex as de-

sired, limited only by the modeler's needs and imagination. A few examples of how mixing

functions can be used are shown below:

Eliminating Unwanted Control Interactions

Adverse

control

interactions

(caused

trim,

model inaccuracies, etc.) can be compensated for

automatically, with the use of the Programmable

Mixing function.

As an example, let's presume that when top

rudder is applied during "knife-edge" flight, an

unwanted movement toward the top of the air-

craft occurs. We can use a Programmable Mixing

circuit to automaticaJly apply a small amount of

DOWN Elevator control with the application of

top (Right or Left!) Elevator.

Setting Method

Select the PROGRAMABLE MIX screen and

press the SET key to display the CHANNEL

SETTING screen.

Select RUD as the Master "mas" channel on

MX1 circuit using the or

key.

Press

the

ACT key to activate the MX2 circuit.

Move the cursor to the R/U and L/D posi-

tions respectively, and set each to +100%.

Direction of mixing may need to be altered,

depending on servo installation, linkage, etc.

10) Flap deflection is more conveniently set in

this case using the AFR program for CH7

(See AFR, page 17).

EXAMPLES OF PROGRAMMABLE MIXING Programmable Mixing combinations are extremely versatile and can be as complex as desired, limited only by the modeler's needs and imagination. A few examples of how mixing functions can be used are shown below: Eliminating Unwanted Control Interactions Adverse control interactions (caused by trim, model inaccuracies, etc.) can be compensated for automatically, with the use of the Programmable Mixing function.
PAGE 2
ADJUSTMENTS AND FLIGHT TECHNIQUES Throttle (CH3) and collective pitch (CH6) are both operated from the Throttle/Collective stick (T/C). The servo response curves for both (collective) pitch and throttle functions can be independently adjusted to give optimum Throttle/Collective relationships at a l l T/C stick positions. (1) CURVE • There are five separate pitch curves: NORMAL — For hovering and normal forward flight. IDLE UP 1 - Used when the Idle Up 1 Throttle function is ON.
PAGE 3
Setting Method • Make the basic linkage settings according to the helicopter manufacturer's instructions, except allow for slightly more total collective pitch travel than specified. •Select the MIX screen and then press the (PITCH) program key. Select the CURVE program by pressing the (CURVE) program key. • Move the cursor to the top left corner of the screen and select the curve that you wish to set by pressing the program key.
PAGE 4
ADJUSTMENTS AND FLIGHT TECHNIQUES • A bar graph along the lower edge of the display indicates the corresponding T/C stick position. 1) Move the standard cursor to the POINT position using the cursor key. 2) Select the graph point to be adjusted with the cursor key. The points are numbered 1 through 12 from left to right on the graph. 3) The Point Cursor is designated by a "+" symbol on the graph.
PAGE 5
(2) PIT HOVERING/PIT-TRIM • HOVERING PITCH trims the pitch setting near the center (hover) point on the T/C stick. Adjustment is possible without changing the High or Low pitch limits. • PITCH TRIM makes parallel shifting of the pitch curve possible without changing the shape of the curve. Setting Method (PIT HOVERING) 1) Select the EDIT screen and move the cursor to Line 2 with the cursor key, the press the program key.
PAGE 6
ADJUSTMENTS AND FLIGHT TECHNIQUES (3) HOVERING OFFSET • The HOVERING OFFSET function programs the EXACT T/C stick hovering position into the computer. This position is incorporated into the pitch curves, and is also the changeover point between UP and DOWN Revolution (rudder or tailrotor) Mixing inputs. Setting Method 1) Select the EDIT screen and move the cursor to Line 2 with the cursor key, then press the program key. 2) Select the PITCH mixing screen by pressing the program key.
PAGE 7
RUDDER Rudder (tail rotor) mixing functions automatically provide trim changes and corrective inputs to the tail rotor to compensate for changes in main rotor torque (due to changes in the T/C stick position). Revolution Mixing Automatic trimming of the tail rotor neutral position is provided in response to Throttle/ Collective changes. As the T/C stick is raised above the center (hover) position, tail rotor pitch is increased and is reduced when the stick is moved below the hover point.
PAGE 8
ADJUSTMENTS AND FLIGHT TECHNIQUES REVO-MIX (Revolution Mixing Setting) 1) Move the cursor to the REVO-MIX line with the cursor key. 2) To set the UP and DN mixing rates, move the cursor to the rate setting position with the cursor keys. Then move the cursor to the UP or DN position with the or cursor key and set the rates with the program keys or the key. (Set the UP side to about 50% and the DN side to about 70% initially.) and 3) Trimming can be performed with the program keys or the REVO.
PAGE 9
SWASH MODE Functions of Swash Mode 1) Five types of swash plate mixing are possible. d) HN3 Type Elevator a) H-1 (normal plate) type b) H-2 Type Aileron (Aileron pitch) Pitch Aileron Fig. 1 Pitch Fig. 3 e) H-4 Type Elevator c) HR3Type Pitch (Aileron) Pitch (Aileron) Fig. 4 Elevator (2ND) (CH8) 2) The rate of the aileron, elevator, and pitch functions can be adjusted (except for H-1). Only Aileron and pitch can be set for H-2.
PAGE 10
ADJUSTMENTS AND FLIGHT TECHNIQUES 4) Set the servos for AIL, PIT, and ELV operation by using the reversing function for each servo. 5) Move the cursor to the rate line with the or cursor key and set the direction of operation of the servos with the program keys. 6) Use the ATV function to set the throw of each servo so that all are equal. 7) Move the cursor to the AIL, ELV, or PIT position with the cursor key and program set the rates with the key.
PAGE 11
5) Move the cursor to the RATE line with the cursor key and set the direction of operation of operation to the servos with the program keys. 6) Use the ATV function to set the throw of each servo so that all are equal. 7) Move the cursor to the AIL, ELV, or PIT position with the cursor key and set the rates with the program keys. 8) Because each servo performs two operations, be sure that the rates are not excessive for the servo mechanics.
PAGE 12
ADJUSTMENTS AND FLIGHT TECHNIQUES THROTTLE CURVE Throttle Curve/Hovering Throttle The throttle (CH3) servo response curve is represented by a graphic display on the right side of the THROTTLE CUR VE screen. The response curve is divided into 11 equal segments by 12 dots or "Points" on the graphic display. Each of the 12 Points can be adjusted up or down on the display to refine the shape of the curve.
PAGE 13
(1) CURVE 1) Move the cursor to the POINT position with the cursor key. 2) Select the curve point on the display that you wish to adjust by using the cursor key. The "Point Cursor" is denoted by a "+" symbol and will be on the point that is selected for adjustment. 3) The point number is displayed in ( ). Points are numbered 1 through 12 from left to right on the display. 4) Each point can be adjusted up or down with the program key. The rate setting for that point is displayed inside the standard cursor.
PAGE 14
ADJUSTMENTS AND FLIGHT TECHNIQUES IDLE UP 1.2 Idle-up 1 and 2 • Idle-Up or "High Idle" functions allow the collective pitch to be reduced while engine speed is reduced to a lesser extent. This allows a more constant engine and main rotor speed during hovering and certain aerobatics. Collective pitch response is improved. • Two separate Idle-Up circuits are provided.
PAGE 15
6) 7) 8) Move the cursor to the RATE line with the cursor key. Set the Idle Up Rate Knobs on the top left of the transmitter to "0". Set the rate for the desired throttle opening at full LOW position of the T/C stick, using the program key. (When the Idle-Up switch is ON.) Initially set the rate for about 40% carburetor opening on IDL1 and about 60 to 70% on IDL2 (actual opening, not the computer display figure). The rates can be trimmed with the Idle Up Knobs.
PAGE 16
ADJUSTMENTS AND FLIGHT TECHNIQUES TH-HOLD Throttle Hold • Throttle Hold is used for practicing autorotations. When the TH-HOLD Switch is pulled, the throttle (CH3) servo moves to a pre-set position (at or near idle) and remains there as long as the HOLD Switch is left ON. Throttle -> Pitch mixing is disconnected, and the collective pitch servo operates over the full range with the T/C stick. • Manual or Auto mode can be selected. In MANUAL mode, TH-HOLD is engaged as described above.
PAGE 17
5) When the T/C stick is moved above the AUTO ON/OFF position, OFF is displayed in ( ) and TH-HOLD is not engaged. As the stick is lowered past the memorized stick point, ON is displayed and TH-HOLD is engaged (if the HOLD Switch in ON). 6) When the stick is above the ON/OFF point and the HOLD Switch is set to ON, the word "PRE" will be displayed at the top left of the screen. As the stick is lowered past the ON/ OFF point, the "PRE" changes to "ON", indicating that TH-HOLD is engaged.
PAGE 18
ADJUSTMENTS AND FLIGHT TECHNIQUES TRIM Trim Authority When Trim adjustments are too sensitive (Ex: One notch on the trim lever in either direction is too much) the Trim Rate (Authority) can be reduced, allowing finer adjustments. Cross Trims Whether or not the Throttle (CH3) and Elevator (CH2) trim levers are "crossed" can be selected. Trim Memory Trim settings can be memorized by the computer, allowing the trim levers and knobs to be returned to neutral position.
PAGE 19
Trim Memory 1) After the model is "trimmed out" and flying well, land and select the TRIM screen. 2) Move the cursor to the TRIM-MEMORY line and press the program key. A message will be displayed asking if the trim data is to be renewed. Press the program key. All trim positions are then "memorized" by the computer. 3) All trim levers featuring Trim Memory can then be returned to their neutral positions.
PAGE 20
ADJUSTMENTS AND FLIGHT TECHNIQUES PARAMETER 4) D/R SW D I R : The ON/OFF directions of the D/R Switches can be selected. In Mode 1, the upper position is the D/R ON (Low Rate) position, and in Mode 2, the lower position is the ON position. 1) Servo Test: Each servo is operated in linear fashion from neutral, to its maximum and minimum positions. The operation is repeated sequentially for Channels 1 through 8.
PAGE 21
MODEL SELECT Model Select Functions 1) Settings and data for up to 6 different models can be stored independently in the transmitter memory. 2) Any one of the 6 programs (models) can be selected for use when desired. 3) Each model can be given a name of up to 8 characters using the NAME function (See page 49). 4) After the Trim Memory function has been performed, the trim positions for each model can be read by selecting the desired model and setting each trimmer to the center position.
PAGE 22
ADJUSTMENTS AND FLIGHT TECHNIQUES Model Copy Function No. 2 program only. The original settings will be retained as is, on the No. 1 program. The MODEL SELECT function can then be used to easily switch back and forth between the old and new setting for comparison (although not in-flight). • As another alternative, settings for a given model could be copied on two or more programs with modifications for different weather conditions, maneuver schedules, etc.
PAGE 23
Move the cursor to Line 3 of the EDIT screen with the cursor key. NAME A model name of up to 8 characters and a user name of up to 10 characters can be input. The user name has a security feature. Once a fourdigit ID number is input, the user name cannot be changed unless the same ID code in input first (The ID code does not appear on the screen after the initial input). The model name and user name are initially set to T9VHP and FUTABA, respectively.
PAGE 24
ADJUSTMENTS AND FLIGHT TECHNIQUES SERVO (Transmitter Test Mode) Transmitter control movements are shown on a bar graph representing servo movement for channels 1 through 8. The center of the graph is the neutral position. The bottom half indicates counterclockwise servo rotation and the top half represents clockwise rotation. Setting Method 1) Select the EDIT screen and move the cursor to Line 3 with the cursor key, then display the SERVO screen by pressing the program key.
