Step 18
Place the aileron servo between the mounting blocks and
use a felt-tipped pen to mark the location of the four servo
mounting screws. Note that the servo must not touch the
hatch in order to isolate engine vibration.
Note: Before mounting the servo, it is
suggested to electronically center the servo
using the transmitter, then install the servo arm
to avoid having to remove the servo and center
the arm later. It may be necessary to slightly
trim one of the servo mounting blocks to clear
the servo wire.
 
Step 19
Remove the servo and use a 1/16" drill bit to predrill
the holes for the servo mounting screws marked in the
previous step. Use the screws supplied with the servo to
mount it to the servo mounting blocks.

Step 20
Connect a 12" Servo Lead Extension (JRPA098) to the
servo lead. Secure the connectors by tying them in a knot
using dental floss (as shown) or by using a commercially
available connector clamp to prevent the servo leads from
becoming disconnected.
Note: It is always a good idea to
secure the servo connector and servo
extension together to prevent the wires
from becoming unplugged.
