-inch Wheels (pr)

Hinging the Control Surfaces

Required Parts

• Stabilizer (2) • Elevator (2)

• Wing (left and right) • Rudder

• Aileron (left and right) • Fuselage

• CA hinge (19)

Required Tools and Adhesives

• Rotary tool • T-pins

• Thin CA

• Drill bit: 1/16-inch (1.5mm)

   Step 1

Use a rotary tool and 1/16-inch (1.5mm) drill bit to drill a hole in the center of each of the three hinge slots in both of the stabilizers.

   Step 3

Position the hinge in the stabilizer. The slot in the hinge will align with the hole drilled in the stabilizer.

   Step 4

Slide the hinges in the elevator. Position the stabilizer and elevator so there is as little gap between the two as possible without restricting movement. Align the tips of the stabilizer and elevator.

Note: While your rotary tool is out, drill the holes in the elevators, ailerons, wing, rudder and fin as well.

   Step 2

Place a T-pin in the center of three CA hinges.

Hinging the Control Surfaces

   Step 5

Apply thin CA to the top and bottom of each of the three hinges. Make sure to saturate each hinge so there is enough CA to wick into the hinge and bond with the surrounding wood.

Note: Do not use CA accelerator on the hinges. The CA must be allowed to wick fully into the hinge to provide the best bond between the hinge and the surrounding wood.

   Step 7

Flex the elevator up and down a number of times to break in the hinges.

   Step 6

Allow the CA plenty of time to cure. Once cured, pull on the elevator and stabilizer to make sure the hinges are fully glued into position.

Hinging the Control Surfaces

  Step 8

Repeat Steps 1 through 8, and using five hinges per aileron, hinge the ailerons to the wing panels.

Landing Gear Installation

 Step 9

Repeat Steps 1 through 8, and using three hinges, hinge the rudder to the fin/fuselage.

Required Parts

• Fuselage • Wheel assembly (2)

• Wheel axle (2) • Cross brace

• Wing strut tab (2) • 4-40 locknut (6)

• 4-40 setscrew (2)

• Assembled shock strut (2)

• Wheel collar w/setscrew (2)

• Main gear strut (right and left)

• 4-40 x 1/2-inch socket head screw (2)

• 4-40 x 5/8-inch socket head screw (4)

• 8-32 x 3/4-inch socket head screw (8)

• #2 x 5/8-inch sheet metal screw (8)

Required Tools and Adhesives

• Threadlock

• Hex wrench (included in kit for wheel collars)

• Phillips screwdriver (#1)

• Hex wrench: 3/32-inch, 1/8-inch

• Nut driver: 1/4-inch

 Step 1

Locate the left and right main gear struts and the wing strut tab. Attach the front of the landing gear using two 8-32 x 3/4-inch socket head screws. The rear is also secured to the fuselage using four 8-32 x 3/4-inch socket head screws, but the wing strut tabs are positioned between the landing gear and fuselage.

Note: Be sure the 6-32 bolts that secure the landing gear legs to the landing brackets are snug to minimize vibration, but allow for movement

Note: Use threadlock on the 8-32 x 3/4-inch socket head screws to prevent them from vibrating loose in flight.

Landing Gear Installation

Note: In Step 2, leave the screws loose in the gear until all the struts and cross brace are in position.

 Step 2

Use two 4-40 x 5/8-inch socket head screws and two 4-40 locknuts to attach the shock struts to the main landing gear struts. The cross brace also uses two 4-40 x 5/8-inch socket head screws and 4-40 locknuts to attach to the gear near the fuselage. Last, use two 4-40 x 1/2-inch socket head screws and two 4-40 locknuts to attach the shock struts to the cross brace.

  Step 4

Secure the wheel collar to the axle by tightening the setscrew onto the flat of the axle with the included hex wrench.

Note: Use threadlock on the setscrew to prevent it from vibrating loose in flight.

  Step 3

Locate the main wheel and remove the front and rear hubs from the wheel.

  Step 5

Slide the rear hub into the wheel. The rear hub is identified as the one without the holes going through the hub for the screws. Slide the longer portion of the axle into the hub, then slide the front hub into the wheel.

Note: The photo does not show the wheel to illustrate how the wheel collar is placed between the two wheel hubs to hide the wheel collar.

Landing Gear Installation

  Step 6

The front and rear hubs will key together when installed properly. Once installed, use four #2 x 5/8-inch sheet metal screws to secure the hubs together. Check the rotation of the wheel when installing the screws. If the wheel does not rotate, loosen the screws slightly until it does.

  Step 8

To complete the wheel installation, snap the hub cap onto the wheel.

  Step 9

Repeat Steps 3 through 8 to install the remaining wheel.

  Step 7

Use a 4-40 setscrew to secure the axle to the main landing gear.

Note: Use threadlock on the setscrew to prevent them from vibrating loose in flight.

Stabilizer Installation

Required Parts

• Fuselage assembly • Stabilizer/elevator (2)

• 6

/8-inch (162mm) joiner • #6 washer (4)

• Tail wheel assembly • 2-56 nut (4)

• 4-40 locknut (3)

• Large strut support bracket (2)

• Small strut support bracket (2)

• #6 x 5/8-inch sheet metal screws (2)

• 4-40 x 5/8-inch socket head screw (3)

• Support rod w/clevis, 10-inch (254mm) (2)

• Support rod w/clevis, 9

/2-inch (241mm) (2)

• 6-32 x 3/4-inch socket head screw (4)

Required Tools and Adhesives

• Threadlock

• Hex wrench: 3/32-inch, 7/64-inch

 Step 1

Slide the 6 in the stabilizer.

/8-inch (162mm) joiner into the forward hole

 Step 2

Slide the stabilizer into the slot in the fuselage. Use two 6-32 x 3/4-inch socket head screws and two #6 washers to secure the stabilizer.

Note: Leave the screws loose until instructed to tighten them.

 Step 3

Slide the remaining stabilizer into the slot in the fuselage. The tubes from the first stabilizer will key into the second stabilizer. Use two 6-32 x 3/4-inch socket head screws and two #6 washers to secure the stabilizer. Once all four screws have been started, tighten each one, but avoid crushing the underlying wood.

Note: Use threadlock on the four 6-32 screws to prevent them from vibrating loose in flight.

Stabilizer Installation

 Step 4

Attach the tail wheel assembly to the fuselage using two #6 x 5/8-inch sheet metal screws. The forward screw goes through the gear and into the fuselage, while the rear screw goes through the two large strut support brackets, then through the gear and into the fuselage.

 Step 5

Attach the two small strut support brackets to the fin using a 4-40 x 5/8-inch socket head screw and a 4-40 locknut. There will be a bracket on the right and left of the fin when complete.

 Step 6

Remove the clevis from each of the support rods. Use a hobby knife to clean the paint from the threads. Thread a 2-56 nut onto the threads, then replace the clevis.

 Step 7

Use a 4-40 x 5/8-inch socket head screw and 4-40 locknut to attach the support rods to the stabilizer. The longer 10-inch (254mm) rod attaches to the top of the stabilizer, while the shorter 9 attaches to the bottom of the stabilizer.
