Note
: The P-47 retract system is designed
to use low profile retract servos, such as the
JRPS791. All adjustments to the retracts are
made before the final installation.
Step 1
Position the retract mechanism over the wing to determine
on which side to mount the retract servo. Use a 4-40 tap
to tap the appropriate holes in the mounting plate.
Step 2
Mount the retract servo to the mounting plate using four
4-40 socket head screws. It may be necessary to install
the spacer plates depending on the servo selected.
Step 3
Attach the servo horn to the retract servo. It is
positioned so the arm moves from one end of the
mechanism to the other.
Step 4
Assemble and install the linkage. Attach the clevis to the
retract actuator, and use a 4-40 screw to attach the ball-
link to the servo arm.
