Checking the Steering Trim (Mode 1 and 2)
Note: Checking the steering trim must be done after
the aircraft has been flown and the rudder trimmed for
straight flight at the transmitter. The steering trim is a
mechanical adjustment and should never be corrected
using the rudder trim at the transmitter.
 9. Once the rudder has been trimmed for straight flight,
you can now adjust the steering trim of your Apprentice.
Taxi the aircraft to determine if it turns left or right when
the rudder stick is centered. Do not change the rudder
trim at the transmitter. If the aircraft turns right, thread
the clevis IN at the rudder servo, which will shorten the
steering linkage. If the aircraft turns left, thread the clevis
OUT at the rudder servo, which will lengthen the steering
linkage. Adjust until the aircraft will taxi in a straight line
without any rudder control inputs.
Aircraft turns right—
Thread clevis IN at rudder servo
Aircraft turns left—
Thread clevis OUT at rudder servo
