Most pilots today are using AVCS Mode. If
you are just starting out, it is recommended that
you use AVCS Mode exclusively from the start.
Normal Mode is rarely used today due to the per-
formance benefits of AVCS mode. When using
AVCS mode all trimming of the tail is automati-
cally handled by the gyro. If you should decide to
use Normal Mode than all trimming and mixing
must be setup by you.
If you will be using the Normal Mode (also re-
ferred to as Rate Mode) then a few changes to the
setup will be necessary. The tail rotor should be
set to 10 degrees of tail rotor pitch (to counteract
torque) when the tail rotor servo is centered. With
clockwise rotating main rotor blades this means
10 degrees of right tail rotor pitch will be neces-
sary to counteract torque. In addition to this it will
be necessary to use the tail rotor compensation or
revolution mixing functions of your transmitter to
help counteract torque. Please see your transmitter
instruction manual for more information on how
to set this up.
If you decide to switch between Normal Mode
and AVCS Mode in flight, you must have the
gyro re-learn the center position after mak-
ing a trim change within the transmitter. To
memorize the new center position simply flip
the gain switch on the transmitter three times
b e t w e e n N o r m a l M o d e a n d AV C S M o d e
(Normal
AVCS Normal AVCS) within one
second. The tail rotor servo will center, indicating
that the new center position has been memorized.
