Optional Retract Door Installation - Horizon Hobby HANGAR 9 OV-10 Bronco 30cc Manuel D'utilisation

OPTIONAL RETRACT DOOR INSTALLATION

 The installation of the retract doors is optional and will
require the use of a computer radio that has a gear door
sequencer. A separate gear door sequencer unit can also be
used. The included retract controller is not compatible with
the number of servos required for this particular model.
 The gear doors are purely cosmetic and have no effect on
how the model flies. They can also be retrofitted at any time.
78. Use a hobby knife and #11 blade to remove the covering
for the nose gear retract in the fuselage. Also remove the
covering for the gear door hinges.
79. Center the retract gear door servo. Place the servo arm on the
servo so it is parallel to the servo centerline.
80. When attaching the linkage to the servo arm, use the hole in
the arm that is 1 inch (25mm) from the center of the arm.
81. Use side cutters to remove the arm that extends away from
the servo, keeping the arm that extends over the servo.
Assemble the link for the gear door, then attach it to the servo
arm using an M3 x 12 button head screw, M3 washer and M3
lock nut. Use a 2mm hex wrench and 5.5mm nut driver.

82. Mount the servo in the opening. The holes for the servo will
need to be drilled and prepared as outlined in earlier sections
of this manual. The output of the servo will face toward the
front of the airframe.
83. Repeat the previous steps to mount the second servo. The
output will mount toward the front of the airframe.
 Using a Y-harness will not work to operate the gear doors, as
one door will open as the other gear door closes. A computer
radio must be programmed to operate the gear door servos.
 Do not mix any epoxy until instructed to do so.
84. Fit the hinges in the gear doors.
85. Fit the hinges into the pockets in the fuselage. The hinges will
be fl ush with the bottom of the fuselage.

86. The gear doors will need to be adjusted to be centered over
the opening for the retract. A thin ruler or hobby knife can be
used to make small changes to their position. Once the fi t has
been checked, the hinges can be secured using 30-minute
epoxy. Make sure to check the position of the gear doors
as the epoxy cures. Allow the epoxy to fully cure before
proceeding.
