(1) RUD Ntr: Rudder servo neutral setting
This parameter is used to set the neutral position of the rudder servo. Po-
sition the rudder servo arm as perpendicular as possible to the tail rotor
pushrod prior to making adjustments with this parameter.
Setting ranges: -240 ~ 0 ~ +240 Initial value: +0
(2) EXP. AVCS / EXP. NORM: Rudder exponential
This parameter sets the feel of the tail rotor control around center. When
set to [0] the control curve is linear. Using a [+] value the tail rotor will be
more sensitive around neutral conversely, using a [-] value will soften the
feeling around neutral. The RUD EXP parameter in your transmitter can
also be used to tune the tail rotor to a desired feeling.
Setting ranges: -100 ~ 0 ~ +100% Initial value: AVCS = -20%, NORM = -20%
Sports = AVCS -60% / NORMAL -40%, 3D = AVCS -20% / NORMAL -20%>
