Follow the steps below to set up the elevator halves. This proce-
dure will help to ensure that excessive sub-trim values are not
used, while at the same time eliminating unwanted elevator dif-
ferential throw.
1. Plug the right elevator servo into the ELEV port of the receiver
and plug the left elevator servo into the AUX 3 port (channel 8)
of the receiver.
2. While in the Wing Type Function (Code 22), press SEL under
TAIL until D/ELEV appears. This selects the Dual Elevator
feature.
3. Turn on the receiver and check the direction of travel of both
elevator servos. If either or both servos are not traveling in the
correct direction, use the REV. SW function (Code 11) to
change the direction of the Elevator or AUX 3 (channel 8)
channels to achieve the proper direction.
4. Perform the following to help minimize the sub-trim settings
and to avoid differential throw in the elevators. Set the sub-
trims for the ELEV and AUX 3 channels to zero using the Sub-
Trim function (Code 15) and center the digital elevator trim on
the transmitter. With the receiver and transmitter turned on,
examine the two servos and notice if the servo arms are at 90°
or perpendicular to the vertical stabilizer. Reinstall the arm if
necessary to achieve as close to a perpendicular position as
possible. Now use sub-trim to adjust the arms so they are per-
fectly perpendicular to the slab.
5. Adjust both elevator halves so that they are perfectly centered
using the mechanical linkage.
6. Now adjust the overall travel of each elevator half using the
Travel Adjust function (Code 12). Adjust the right elevator
with the ELEV function in Travel Adjust in both the up and
down directions. Now adjust the left elevator using the AUX.3
Travel Adjust to match the travel of the right elevator in both
directions.
Note: Once the right and left elevator throws have been syn-
chronized, use the Trace Rate function (Code 14) to adjust the
throw of both elevators simultaneously. The Trace Rate function
eliminates the need to individually measure and adjust the throw
of each servo when more that one channel is used for the elevator,
aileron, or rudder.
