6. Install the tail wheel onto the wire and secure it in place
with a nylon retainer. Confi rm that the tail wheel rotates

INSTALL THE TAIL SERVOS
AND PUSHRODS
The tail servos can be installed in either the forward or aft 
position for balancing purposes. If using the recommended 
equipment, you will want to install the servos in the forward 
position. If you plan to use a motor and/or battery that is 
heavier than our recommended setup, you may wish to install 
the tail servos in the aft position to minimize or eliminate any 
additional tail ballast that would be needed to balance the 
plane at our recommended C.G. For aft servo installation 
directions, look ahead to the end of this section.
