The Normal pitch curve function contained in the Basic Menu sets the normal
(NORM) curve. The Normal pitch curve is the basic pitch curve for flight near
hover. Together with the normal throttle curve, the normal pitch curve is adjusted
for best vertical performance at a constant engine speed. You can program the
response over a 5-point curve so that you may choose the best rotor pitch angle
relative to throttle stick movement. Each of the five points can be adjusted over a
0% to 100% range.
The T8U system helicopter programs contain five pitch curves: normal, idle-up 1
(IDL1), idle-up 2 (IDL2), hold (HOLD), and inverted (INVR). The basic normal
pitch curve is the only one displayed in the Basic Menu, but all of the pitch curves can
be viewed in the Advance menu. The Normal curve is the same in both the Advance
and Basic Menus.

Data input keys
These keys are used to move
between the five points in the
PI-CRV function.
1. Turn the PI-CRV function ON
by pressing the (+) key ("ON"
displayed). Turn off (INH) the
function with the (-) key.
2. Input 5-point curve values
Move the lower arrow to the
position you want to set with the
CURSOR keys (the curve point is
indicated by the arrow below the
numbers 1-5, and the current
throttle position is above the
numbers). Enter the desired curve
value with the (+)/(-) keys.
• If you're unhappy with what you've
set, you may return to the default
value by pressing the (+) and (-)
keys simultaneously.
Initial values:
POS1 = 0%
POS2 = 25%
POS3 = 50%
POS4 = 75%
POS5 = 100%

function is on at startup.
The bottom arrow shows the point on
the five-point curve currently being set.
The blinking item on the
setting screen is the
