direction setting by changing the signs of the numbers in the curve from plus (+) to minus (-) and vice versa.
Suggested defaults:
Clockwise rotation: -20, -10, 0, +10, +20% from low throttle to high.
Counterclockwise rotation: +20, +10, 0, -10, -20% from low throttle to high.
Adjust to the actual values that work best for your model.
Revo. Curves for idle-ups are often v-shaped to provide proper rudder input with negative pitch and increased
throttle during inverted flight.(Rudder is needed to counter the reaction whenever there is increased torque. In
inverted flight, throttle stick below half has increased throttle and negative pitch, therefore increasing torque
and rotating the helicopter unless the revo. Mix is also increasing appropriately.)
Note: The throttle and pitch curves for the normal condition is always on. They cannot be inhibited. The
other four conditions are activated with their throttle curves or throttle hold.
• 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.
• 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.
