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°,ifavailable, 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 MODE/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.
