V-TAIL (FIND IN ACRO FUNCTION MENU 3.3.10)

4.3.4 OFFSET (GLID 2A+2F):

Additional flight conditions are available specifically for sailplanes.

 

 

These additional flight conditions contain different offset trims to make the sailplane perform certain maneuvers more easily. Aileron differential functions may be set to provide separate rates per condition selected.

Prior to setting up OFFSET, you must active the conditions and assign the switches in the CONDITION/FUNCTION.

Unnecessary fuselage motion is generated when there are sudden changes in the servo position and variations in the operating time between channels can be suppressed by using the delay function.

Note: The same delay amount for elevator and rudder is recommended when using V-tail function.

The AT9 provides 5 additional setups along with the normal flight condition. (NORMAL,

START, SPEED, DISTANCE and LANDING) These offset trims have same setting abilities basically except the switch and dial assignment. For an example of trim settings, please see the following:

ADJUSTABILITY:

• Separate adjustments for each aileron, elevator, rudder and flap servo, for each condition.

• SWITCH G (AT10) or E (AT10) is programmed for NORMAL, START, and SPEED trims. SWITCH C is programmed for DISTANCE and LANDING trims. These switch/position assignment is adjustable. (CONDITION/FUNCTION)

• TRIM item (Digital trim operation mode):

NORM: normal trim operation mode.

MIX: offset rate trim operation mode while mixing is on.

• Optional assignable knob (CAMBER MIX) to allow trimming in flight of the aileron and flap action of each flight condition.

• During OFFSET operation, the aileron and elevator travels are displayed on each trim display in the Startup screen.

 

 

Goals	Steps	Inputs
Set up a START to gain maximum possible lift on launch. Each Aileron: 50%. Each Flap: 100%. Elevator: -5% to compensate. SWITCH (AT9=G, AT9=E.) Note: switch is assignable. (CONDITION) KNOB(null) Note: knob is assignable. (CAMBER MIX)	Open OFFSET function	to BASIC. again to ADVANCE to OFFSET,
Switch to the START condition.	G or E from NORMA to START

4.3.5 START DELAY (GLID 1A+1F only):

 

START DELAY automatically switch the offset trims (OFFSET) from the START condition's trims to the normal conditionЎЇs trims after proceeding the delay time (max.10sec.) which is set by the -dly- item when activating the START condition. (It is convenient for hand launch glider.)

Note: The same delay amount for elevator and rudder is recommended when using V-tail function.

ADJUSTABILITY:

• Delay time (-dly-) range of 0 to 100%. The delay time is 10 second at 100%.

 

 

Goals	Steps	Inputs
Ex: delay time=5 second.	Open ADVANCE menu,then open START DELAY.	to BASIC. again to ADVANCE to START-DLY,
Activate the function	to MIX Ј to OFF or ON
Set the delay time. (Ex:50% each surface)	to ELEV Ј to 50% to RUDD Ј to 50% Repeat as needed.

CHAMBER-FLP

CAMBER FLAP assigns the primary flap control [defaults to VR(A)] to allow trimming in flight of the flap action. The up and down travel of each flap (camber flaps: FLP1/2) can be adjusted independently. Also the center position of flap servo can be offset.

Note: If FLAP-TRIM is activated, you can not use CAMBER FLAP function simultaneously.

 

ADJUSTABILITY

• Rate: -100% to +100%, with a default of +30%

• Center position (CENTER): The operation reference point of flap can be offset. -100% to +100%, with a default of 0%.

Note: When changing the polarity of a rate, "change rate dir?" is displayed for a check. Please set up after pressing DIAL for 1 second and canceling an alarm display.

 

Goals	Steps	Inputs
Ex: Set the maximum travel of 35% of the total flap travel.	Open the CAMBER FLAP function.	to BASIC. again to ADVANCE to CAMBER-FLP,
Adjust the up/down trim amount separately.(Ex: adjust to 35%)	to FLP ЎЈ VR (A)Ј to 35%Ј VR (A)Ј to 35%Ј ЎЈ Repeat.
Or: adjust the center position of flap servo	to CENTER Ј to desired point.

4.3.7 Camber Mixing:

This function adjusts the mixing rate of camber operation which operates the wing camber (ailerons and flaps) in the negative and positive directions. The aileron, flap, and elevator rates can also be adjusted independently and attitude changes caused by camber operation can be corrected.

Also the operation reference point of camber control can be offset. (PRE)

 

Note: Camber control is not assigned at initial.

ADJUSTABILITY:

• Rate: -100% to +100%, with a default of +30%

• Reference point (PRE): The operation reference point of camber control can be offset. -100% to +100%, with a default of 0%.

 

 

Goals	Steps	Inputs
Ex: set the mixing amount for aileron to 40%, camber control to VR (E), reference point to desired point.	Open the CAMBER MIX function.	to BASIC. again to ADVANCE to CAMBER-MIX,
Choose desired slider.	to VR Ј to VrA
Adjust the mixing amount for AILE. (Ex: adjust to 40%)	to FLP to VrA Ј to 40%, to VrA Ј to 40%Ј
Set the reference point.	to PRE Ј or VrA to desired point for 1 sec.

BUTTERFLY (crow) mixing

 

 

BUTTERFLY simultaneously moves the flaps, twin ailerons and elevator, and is usually used to make steep descents or to limit increases in airspeed in dives. Separate two BUTTERFLY settings are available. (CRI1/CRI2)

ADJUSTABILITY:

• Activation: Get proportional by moving the THROTTLE STICK.

• Switch: Mix SWITCH is selectable. A to H: SWITCH A to H. Also LOGIC SW (Lsw1 to 3) may be assigned. NULL: always on.

• Inversely proportional to THROTTLE STICK: provides a proportional increase in amount of airbrake action as THROTTLE STICK is lowered (when SWITCH A (assignable) is in down position). Includes selectable stick position where airbrake begins. If you would like to have the airbrake be directly proportional to throttle stick, you will need to reverse the THR-REV function.

Note: this changes the throttle stick direction for all models.

INSTRUCTIONS:

• Elevator settings: (Adjustable in the B.FLY-ELE)

B.FLY-ELE works linking with BUTTERFLY function. Elevator rate is adjustable in a 3 point curve.

Point 1: PRESET point. (Fixed)

Point 2: MID point. Position and rate are adjustable.

Point 3: END point. Position and rate are adjustable.

• Delayed reaction: You can suppress sudden changes in your model's attitude when BUTTERFLY is activated by setting the delay (DELAY) item, to slow down the elevator response, allowing the flaps/ailerons/elevator to all reach their desired end point together. A setting of 100% slows the servo to take approximately one second to travel the prescribed distance.

• Channels controlled: Twin ailerons, flap and spoiler may be set independently in BUTTERFLY, including set to 0 to have no effect.

• Twin aileron servos: If AIL-DIFF function is inhibited, then AIL1 and AIL2 settings will have no effect. If AIL-DIFF is active, then CH1 and CH7 may be independently adjusted.

• Normally both ailerons are raised equally in BUTTERFLY, and the elevator motion is set to maintain trim when the ailerons rise. Different amounts may be set for each aileron to correct for torque reactions and other unique characteristics of the model.

Be sure you understand what dropping ailerons will do when in BUTTERFLY. Along with creating an enormous amount of drag (desirable for spot landings), this also creates "wash-in", a higher angle of attack where the ailerons are, and encourages tip stalling. If you are using this for aerobatic performance and not "sudden stops", consider raising the ailerons and dropping the flaps in stead as shown in the diagram above.

 

 

Goals	Steps	Inputs
Activate BUTTERFLY. Adjust the aileron and flap travel to 75% Elevator setting are adjustable in the B.FLY-ELE.   MIX switch is selecable	Open the BUTTERFLY function	to BASIC. again to ADVANCE to BUTTERFLY,
Activate the function	SWA to UP position to MIX Ј to OFF
Adjust the travels as needed. (Ex: Aileron each 75%,Flap 75%)	to AIL1 Ј to 75%Ј to FLP Ј to75%Ј to AIL2 Ј to 75%Ј

AILE/ RUDD MIX

 

You can select a pre-programmed mix which is used to mix the rudders with aileron operation or the ailerons with rudder operation.

Aileron-to-rudder mix (AILE􀄺RUDD): automatically creates a "coordinated turn".

Rudder -to-aileron mix (RUDD􀄺AILE): used to counteract undesirable roll (roll coupling) that happens with rudder input, especially in knife-edge.

ADJUSTABILITY:

• RATE range of -100 to +100. Negative setting would result in opposite rudder (aileron) action from aileron (rudder).

• SWITCH A-H fully assignable. Also LOGIC SW (Lsw1 to 3) may be assigned.

• POSITION fully assignable, including NULL (mix always on) and Up&Cntr and Cntr&Dn to activate the mix in 2 separate positions of the same SWITCH.

• Condition: The separate AILE􀀒RUDD setting for each flight condition can be set.

 

Goals	Steps	Inputs
Ex:RUDD-AILE,25%,no switch,corrects roll coupling.	Open AIL/RUD-MIX submenu.	to BASIC. again to ADVANCE to AIL/RUD-MIX,
Select the mixing mode.	to MODE Ј to RUDD-AILE
Activate the function	to MIX Ј to ON
Set the rate (Ex:100% each way)	to RATE RUDDER STICK Ј to +25% RUDDER STICK Ј to +25%
