With the right wing panel once again upside down on the building
board, determine the aileron servo location (2nd wing bay in from the
inboard edge of the aileron). Using a felt tip pen, draw a cutting line

edges using a heating iron. (Photos 5, 6 & 7)

Obtain two servo extensions that give you the necessary lead
length for your aileron servos (12" or so). Join the aileron servo and
servo extension. Cover the connection with heat shrink tubing pro-
vided and using a heat gun shrink the tubing over the connectors.
