THR-CURVE and PIT-CURVE: These 5-point curves are utilized to best match the blade collective pitch to the engine RPM for
consistent load on the engine. Curves are separately adjustable for normal, idle-up 1 and idle-up 2. In addition,
a separate collective pitch curve is available for throttle hold. Sample curves are displayed in the appropriate setup types
(ex: normal flight condition, p. 65) for clarity.
Suggested defaults:
• Normal: Collective pitch curve that results in points 1, 3 and 5 providing -4, +5, (+8 to +10)* degrees pitch. A throttle
curve setting of 0, 30, 50, 70, 100%.
• Idle-up 1: Idle-ups 1 is typically the same except for the gyro settings, with heading-hold/AVCS mode.
The pitch curve will likely be similar to the normal curve above.
• Idle-up 2: Collective pitch curve that results in points 1, 3 and 5 providing (-8 to -10), 0, (+8 to +10) degrees. A
throttle curve of 100, 75, 50, 75, 100 to provide full throttle for inverted maneuvers.
• Throttle Hold pitch curve: Start with the normal pitch curve (for inverted autos, start from the idle-up 2 pitch curve), but
increase the last point approximately 1-2¡, if available, to ensure sufficient pitch at landing.
*(These default recommendations assume 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 adjusted by the modeler to maintain constant RPM even when the collective pitch is reduced
during flight (including inverted).
• To change which condition's curve is being edited, simply press the M
ODE/PAGE BUTTON to scroll through the curves
available, or cursor up above point 1 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.
•
Idle-ups and throttle hold pitch curves may be edited even before the conditions have been made active or while they
are active but not selected.
REVO. MIX: This linear curve mix adds opposite rudder input to counteract the changes in torque when the speed and
collective pitch of the blades is changed.
Adjustability:
• REVO.MIX: normal for hovering and idle-ups (1 and 2) combined.
• REVO.MIX is editable in the BASIC and ADVANCE menu.
