Revo Mix - RadioLink AT9 Instruction Manual

• Normal: Collective pitch curve that results in points 1, 4 and 7 providing .4, +5, (+8 to +10)* degrees pitch.
A throttle curve setting of 0, 25, 36, 50, 62.5, 75, 100%.
• Idle-ups 1 & 2: Idle-ups 1 and 2 are typically the same except for the gyro settings, with one being
heading-hold/AVCS and the other being normal mode. The pitch curve will likely be similar to the normal
curve above.
• Idle-up 3: Collective pitch curve that results in points 1, 4 and 7 providing (.8 to .10), 0, (+8 to +10)
degrees. A throttle curve of 100, 75, 62.5, 50, 62.5, 75, 100 provide full throttle for inverted maneuvers.
• Throttle Hold pitch curve: Start with the normal pitch curve (for inverted autos, start from the idle-up 3
pitch curve), but increase the last point approximately 1-2°, if available, to ensure sufficient pitch at landing.
This default recommendation assumes you are doing forward flight. If you are just learning, please follow
your instructor's guidance. Some instructors like a +1 base point for training so that the helicopter comes
down very slowly, even if your instincts pull the throttle/collective stick to the bottom in a hurry.
ADJUSTABILITY:
• Normal condition curves are editable in the BASIC menu for convenience.
• All curves may be adjusted in the ADVANCE menu.
• Automatically selected with the proper condition.
• The idle-up curves are programmed to maintain constant RPM even when the collective pitch is reduced
during flight (including inverted).
• To change which condition's curve is being edited, cursor up to <COND> and change the curve named.
• For clarity, the name of the condition currently active (switched on in the radio) is shown in parentheses
behind name of condition whose curve is being edited. (Example: see curve displays below. Note that the
normal condition is active but the idle-up 1 condition's curves are currently being edited.
• Moving and deleting the curve point: The curve point (-stk-) can be moved to the left or right by turning
the DIAL (up to 2% in front of the adjoining point) and deleted/returned by pressing the DIAL for one
second alternately.
• Idle-ups and throttle hold pitch curves may be edited even before the conditions have been made active.
Activating their throttle curves activates these conditions.

5.3.2 REVO MIX:

This 5-point curve mix adds opposite rudder input to counteract the changes in torque when the speed and
collective pitch of the blades is changed.
ADJUSTABILITY:
• Three separate curves available: normal for hovering; idle-ups 1 and 2 combined; and idle-3.
• Normal condition curves are editable in the BASIC menu for convenience.
• All curves may be adjusted in the ADVANCE menu.
• Correct mix is automatically selected in-flight with each condition and automatically activated when the
throttle setup for that condition is activated in the programming (i.e. THROTTLE HOLD or THR-CURVE.)
• To change which condition's curve is being edited, cursor up above POINT5 and select. For clarity, the
name of the condition currently active (switched on at the radio) is shown in parentheses behind the name of
the condition whose curve is being edited.
Revo. Mixing rates are 5-point curves. For a clockwise-turning rotor, the rudder is mixed in the clockwise
direction when collective pitch is increased; for counterclockwise-turning, the opposite. Change the
operating direction setting by changing the signs of the numbers in the curve from plus (+) to minus (-) and
vice versa.
