Note that the normal throttle, pitch and revo curves are all available in the
BASIC
menu for simplicity. These may also be
updated later in the
ADVANCE
menu with the settings for the other 4 conditions [idle-up 1 (
IDL1
), idle-up 2 (
IDL2
) and idle-
up 3 (
IDL3
), plus throttle hold (
HOLD
)]. Note: The throttle and pitch curves for the normal condition are always on. They
cannot be inhibited. The other four conditions are activated with their throttle curves or throttle hold. For idle-ups, see p.
81. For throttle hold, see p. 79.
•
THR-CURV/NOR
: inputs the normal (
NORM
) throttle curve, which is usually not a linear response to
THROTTLE STICK
motion. Adjusting point 4 of the curve adjusts the engine’s RPM at the
THROTTLE STICK
midpoint . the desired
position for hovering. The other 6 points are then adjusted to create the desired idle and maximum engine speed, and a
smooth transition in-between. For more on throttle curves, see p. 80.
•
PIT-CURV/NOR
: inputs the normal (
NORM
) collective pitch curve, the collective pitch curve for flight near hover. The
normal collective pitch curve is adjusted to match the throttle curve, providing the best vertical performance at a constant
engine speed, with a starting curve of .4 base, +5 neutral, and +8 to +10 degrees of blade pitch maximum*. You can
program the response over a 7-point curve for the best collective pitch angle relative to
THROTTLE STICK
movement.
For more on collective pitch curves, see p. 80
•
REVO./NORM
: mixes collective pitch commands to the rudder (a
PITCH-RUDDER
mix) to suppress the torque generated
by changes in the main rotor's collective pitch angle, keeping the model from yawing when throttle is applied.
NOTE: There are three revo. mixes available: normal (
NORM
LGOHXS
IDL1/2
), and idle-up 3 (
IDL3
). All 3 are
adjustable in the
