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.
• 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.
• 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), idle-up 1/2 (IDL1/2), and idle-up 3
(IDL3). All 3 are adjustable in the ADVANCE menu. Never use revo mixing in conjunction with
heading-hold/AVCS gyros. For details on revo, including default points for clockwise and
counterclockwise rotating rotors.
