STEP 2: INSTALLING THE MAIN LANDING GEAR DOOR ACTUATORS

❑ Glue one hinge into the precut slot in one end of each plywood plate.

❑ Glue one prebent wire bracket assembly onto the bottom of the

opposite end of each plywood plate. Each bracket assembly should be

centered over the plywood plate and ush with the back edge.

❑ Drill a 1/16" diameter hole through the center of each plywood plate.

Position each hole 1-3/8" (35mm) back from the hinged edge.

 The wire leg on one side of each prebent wire bracket assembly is longer than the other leg. When

assembling the main landing gear door actuators, make sure to make one right and one left.

 When you install the landing gear door actuator assemblies in the next procedure, make sure to install

the right actuator assembly into the right fuselage boom and the left actuator assembly into the left fuselage boom. It's

important that the shorter leg on the wire bracket assemblies is toward the inside of the fuselage booms. Also note that

the hinge should be toward the bottom of the plywood plate when mounted.

❑ Hook the outer hole in each actuator horn over the wire brackets and

install the actuator horn onto the landing gear doors, using epoxy and the

eight wood screws provided. Position the center of each actuator horn 5/8"

(16mm) in front of the back edge and 3/4" (19mm) below the outer edge

of the landing gear doors. Angle the actuator horns slightly to line up with

the angle of the wire brackets.

❑ Carefully cut the wood screws off ush with the outside of the landing

gear doors.

 Two of the four plastic actuator horns are cut shorter. These shorter actuator horns should be installed

onto the shorter leg of the wire brackets on the inside of the fuselage booms.

❑ Test the functionality of the landing gear doors. When the main gear is down, the landing gear doors should be held open by the

springs. When the main gear is retracted, the wheels will hit the plywood plates and pull the landing gear doors closed. When the main

gear is fully retracted, the landing gear doors should be fully closed and ush with the outside of the fuselage booms. If the landing gear

doors are pulled below the outside of the fuselage booms, glue a 1/8" (3mm) wide plywood stop to the front and back of the landing gear

bay to keep the landing gear doors ush with the fuselage booms. If the landing gear doors need to be held wider apart when down,

gently bend the wire actuator legs apart slightly.

❑ Install the landing gear door actuator assemblies into the fuselage

booms, using the four wood screws provided. The front of each plywood

plate should be 5/16" (8mm) down from the top of the landing gear bulkhead

and the inside edge of each plywood plate should be 3/8" (10mm) from the

inside edge of the fuselage boom.

❑ Drill a hole just below the top of each landing gear

bulkhead 1/8" (3mm) in from the edge of the plywood

plate, then install the spring, as shown.

STEP 3: INSTALLING THE NOSE LANDING GEAR DOORS

❑ Hinge the nose landing gear doors and install the actuator, using the

same techniques that you used to install the main landing gear doors

and actuators. There are only a few differences: Position each hinge

1" (25mm) in from the front and rear edges of the landing gear doors

and install the actuator assembly so that it's hinged from the top, not the

bottom, like on the main gear actuators. The bottom of the plywood plate

should be even with the bottom of the U-Shaped cutout in the bulkhead.
