- Page 4 STEP A Step A-01: Hinging Introduction Hinging is one of the most important parts of assembly on an EPP Foamy, so it is very important to perform this step correctly. If performed incorrectly, your control surfaces may bind and not deflect properly.
- Page 5 STEP A Step A-03: Hinging - Creating the Elevator Hinge Spread the glue out with a used hobby-blade. Step A-04: Hinging - Aileron Hinging Repeat Steps A-01 through A-03 for both ailerons as shown...
- Page 6 STEP A Step A-05: Hinging - Rudder Hinging (Top Half) Repeat steps A-01 through A-03 for the TOP HALF of the rudder only You will hinge the bottom half of the Rudder during a later part of the assembly. Step A-06: Hinging - Completion Once satisfied, let the Elevator, Ailerons, and Rudder hinges sit for approximately 1-2 hours to allow the glue to dry.
- Page 7 STEP B Step B-01: Horizontal Fuselage Assembly - Nose Piece Your horizontal fuselage should now be in 3 pieces (The nose piece, a complete wing, and a rear horizontal fuselage with elevator). Using Welders Adhesive, glue these three pieces together. Apply a bead of Welders Adhesive to the rear of the Horizontal Nose where it meets the front of the wing.
- Page 8 STEP B Step B-03: Horizontal Fuselage Assembly - Wing Spar The wing spar is installed on the bottom of the horizontal fuselage into a pre-cut slot. Start by removing the excess foam from the wing spar slot, and test fit the wing spar in place. Rough up the sides of the carbon spars with a some sand paper or a sanding stick.
- Page 9 STEP C Step C-01: Lower Vertical Fuselage Assembly Now, you will attach the lower half of the vertical fuselage to the horizontal fuselage. Apply a bead of Welders Adhesive to the Lower Vertical Fuselage where it meets the horizontal fuselage, and temporarily install.
- Page 10 STEP C Step C-03: Lower Vertical Fuselage Assembly - Carbon Bracing On the bottom of the horizontal fuselage and on the sides of the vertical fuselage, you will see some small dots along the edges. These small dots are where your carbon braces will attach. Set your fuselage upside down on a flat surface, and start by attaching the two 5”...
- Page 11 STEP D Step D-01: Control Horn Installation - Ailerons Start by removing the Aileron Control Horn from the supplied ply-wood hardware kit, and find the slot in the ailerons where the control horns will be installed. Control horns are installed in a similar fashion to the wing spar.
- Page 12 STEP D Step D-03: Servo Installation - Ailerons Apply a generous amount of Welders Adhesive to the sides and bottom of the Aileron Servo, and slide it into the pre-cut slot in the TOP of the horizontal fuselage. Step D-04: Servo Installation - Z-Bends Using side-cutters, cut a 1.0”...
- Page 13 STEP D Step D-05: Servo Installation - Control Rods Tape the ailerons to the horizontal fuselage so that they are parallel to the horizontal fuselage. Cut a V-shape out of a piece of scrap ply-wood or card-stock. This piece will be used to protect the foamy in the next step. Step D-06: Servo Installation - Control Rods Cut two pieces of heat shrink tubing that are approximately 1”...
- Page 14 STEP D Step D-07: Servo Installation - Control Rods Center the servo, and verify again that the aileron is parallel to the horizontal fuselage, and then slide the V-shaped protector that you made earlier around the control horn and use a heat gun or lighter to shrink the heat-shrink tubing around the carbon rod and Z-bend on both ends.
- Page 15 STEP D Step D-09: Top Vertical Fuselage Installation Repeat step C-01 to install the top of the vertical fuselage onto the horizontal fuselage. Once installed, ensure the elevator is still able to achieve 45degrees of throw. If it cannot, trim any excess foam necessary to achieve maximum throw. Step D-10: Top Vertical Fuselage Installation - Hinging Rudder Bottom Repeat step A-01 through A-03 and hinge the bottom half of the rudder.
- Page 16 STEP D Step D-11: Top Vertical Fuselage Installation - Motor Mount Repeat step C-01 to install the foam part of the motor mount onto the fuselage. Glue should be applied everywhere that the foam motor mount will touch the horizontal and vertical fuselages. Step D-12: Top Vertical Fuselage Installation - Motor Mount (OPTIONAL) This step is optional.
- Page 17 STEP E Step E-01: Electronics Installation - Motor To install any bolt-on motor, simply install the X-mount to the back of your motor, center it on the ply-wood motor mount installed in step D-10, and screw in place with small wood screws. To install the recommended Hacker A10-9L, first install the phenolic x-mount to the motor.
- Page 18 STEP E Step E-03: Electronics Installation - Elevator Servo Repeat Step D-02 to install one of the single-side servo arms onto the elevator servo. Step E-04: Electronics Installation - Elevator Servo Repeat Steps D-03 through D-08 to install the Elevator Servo and Elevator Servo Pushrod and Z-bends.
- Page 19 STEP E Step E-05: Electronics Installation - Rudder Servo Repeat Step D-01 to install a LONG control horn into the LEFT side of the rudder. This is the side OPPOSITE of the carbon bracing. Step E-06: Electronics Installation - Rudder Servo Repeat Steps D-02 through D-08 to install the Rudder Servo and Rudder Servo Pushrod and Z-bends.
- Page 20 STEP E Step E-07: Electronics Installation - Speed Controller Using either bullet connectors or direct-soldering, connect the speed controller to the motor and adhere the speed controller to the fuselage with Welders Adhesive. Step E-08: Electronics Installation - Receiver Adhere your receiver to the side of the fuselage using Welders Adhesive. You can route wires to your receiver by poking small holes in the fuselage and running the wires through the holes.
- Page 21 SETUP Step F-01: Completion Congratulations! You have finished assembly of your 33” Extra 330 SC. Now it’s time for Setup. At this time, you can setup your control throws, exponential and center of gravity. Please refer to the recommended setup sheet at the end of the manual for our setup recommendation. Once you have determined where your battery must be located to obtain the correct Center of Gravity, install your preferred method of mounting the battery.
