5.3 HELI-SPECIFIC ADVANCE MENU FUNCTIONS
5.3.1 THR-CURVE and PIT-CURVE:
These 7-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, idle-up 2, and
idle-up 3. 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) for clarity.
Suggested defaults:
• 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 curves that result 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
